MIME Class

Properties   Methods   Events   Config Settings   Errors  

The MIME class allows for the simple encoding and decoding of MIME structures, such as message attachments and file uploads.

Syntax

ipworkssmime.mime()

Remarks

The class may be used for decoding or encoding of messages. Message holds the content of the encoded message or the filename that holds the encoded data. The decoded data are provided in Parts properties.

To decode a MIME message, you should first assign either the whole message (headers and body) to Message or put the message headers into the MessageHeaders property and the message body or the filename holding it into the Message property. Calling DecodeFromFile or DecodeFromString directs the class to start parsing the message: it will fill out the ContentType and ContentTypeAttr properties with message content-type information, and it will enter information about message parts into the Parts properties, which includes part sizes, part content types, part content type attributes, part content disposition, part content disposition attributes, part encoding, part name, part filename, part headers, or part content (part-decoded string or part-decoded file) for each decoded part.

Calling the DecodeFromString or DecodeFromFile to decode does not actually decode the message but only parses it. The real decoding is done when the part content in the Parts properties is first accessed.

To encode data into a MIME message, you should first assign values for each part to either a part-decoded string or a part- decoded file in the Parts properties property, and optionally assign values to the other part attributes in the Parts properties. Assigning a value to the part-decoded string or a part-decoded file through the Parts properties, fills out automatically the part headers into the Parts properties for the respective part. Calling EncodeToFile or EncodeToString directs the class to fill out the Message with the message body and the MessageHeaders with the headers.

The Progress event is fired as the message is parsed and the data are decoded/encoded.

MIME.Boundary Property

This property includes the boundary separating the MIME parts. It has a maximum length of 80 bytes.

Syntax

getBoundary(): string;
setBoundary(boundary: string): void;

Default Value

""

Remarks

This property contains the boundary separating the MIME parts and has a maximum length of 80 bytes. The class automatically generates a random boundary value during encoding, if no value is given. During decoding, this property is filled with the boundary from the actual MIME message.

The class will truncate any string longer than 80 bytes if assigned to Boundary.

MIME.ContentType Property

This property includes the value of the content-type header of the message that was encoded/decoded.

Syntax

getContentType(): string;
setContentType(contentType: string): void;

Default Value

""

Remarks

This property contains the value of the content-type header of the message that was encoded/decoded. The class filters it out from the MessageHeaders. It shows the user information about the type of the parts and their relation to each other.

The content-type attributes, such as filename, boundary, and charset, are held in this property.

MIME.ContentTypeAttr Property

This property includes the attributes of the content-type header of the message that was encoded or decoded.

Syntax

getContentTypeAttr(): string;
setContentTypeAttr(contentTypeAttr: string): void;

Default Value

""

Remarks

This property contains content-type attributes such as "filename", "boundary", and "charset".

MIME.Message Property

This property contains the encoded message text or a path to a file that contains the encoded message text.

Syntax

getMessage(): Uint8Array;
setMessage(message: Uint8Array): void;

Default Value

""

Remarks

This property contains the encoded message text or a path to a file that contains the encoded message text. The class fills out this property with the message body and MessageHeaders during encoding. The user may assign both the headers and the body to this property and leave MessageHeaders empty before decoding.

This property is not available at design time.

MIME.MessageHeaders Property

This property includes the headers of the MIME message.

Syntax

getMessageHeaders(): HeaderList;
setMessageHeaders(messageHeaders: HeaderList): void;

Default Value

Remarks

This property contains the headers of the MIME message. The class fills out this property upon encoding. The user should use them as additional headers when emailing the Message.

During decoding, if this property is empty, the class will try to find the headers in the beginning of the Message and then will fill out this property accordingly.

Please refer to the Header type for a complete list of fields.

MIME.MessageHeadersString Property

This property includes the string version of the MIME message headers.

Syntax

getMessageHeadersString(): string;
setMessageHeadersString(messageHeadersString: string): void;

Default Value

""

Remarks

The component fills out MessageHeadersString upon encoding. The user should use these strings as additional headers when emailing the Message.

This property contains a string version of the MIME message headers. During decoding, if this property is empty, the class will try to find the headers in the beginning of the Message and will fill out this property accordingly.

MIME.Parts Property

This property contains information about all parts of a MIME message.

Syntax

getParts(): MIMEPartList;
setParts(parts: MIMEPartList): void;

Default Value

Remarks

This property contains information about all parts of a MIME message. A MIME message consists of different parts, separated by either a user-specified or an auto-generated boundary. Each part has its own set of headers that are contained in the field.

The MIMEPARTS collection is filled out by the class when a call to either DecodeFromFile or DecodeFromString is made. However, when the EncodeToFile or EncodeToString methods are called, the class encodes the data given in either or into a MIME message.

Please refer to the MIMEPart type for a complete list of fields.

MIME.config Method

Sets or retrieves a configuration setting.

Syntax

async mime.config(configurationString : string): Promise<string>

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

MIME.decodeFromFile Method

This method decodes from a file.

Syntax

async mime.decodeFromFile(): Promise<void>

Remarks

This method decodes the data file given in Message and optionally MessageHeaders and fills out the Parts properties for each decoded part.

Example. Decoding from a File:

MIMEControl.Message = "C:\filename.txt" MIMEControl.DecodeFromFile

In this example, C:\filename.txt must contain the MIME headers and body. If not, the MessageHeaders property must be set to the appropriate MIME headers.

MIME.decodeFromString Method

This method decodes from a string.

Syntax

async mime.decodeFromString(): Promise<void>

Remarks

This method decodes from a string. It is the same as DecodeFromFile, but now the Message denotes the real encoded message rather than a filename.

This method decodes the data given in Message and optionally MessageHeaders and fills out the Parts properties.

Example. Decoding a Mail Message:

MIMEControl.MessageHeadersString = MailControl.MessageHeaders MIMEControl.Message = MailControl.MessageText MIMEControl.DecodeFromString

MIME.decodePart Method

This method decodes the specified part.

Syntax

async mime.decodePart(index : number): Promise<Uint8Array>

Remarks

This method decodes the part specified by Index and returns the decoded part data.

DecodeFromString or DecodeFromFile must be called before calling this method. Calling this method will return the decoded bytes, and in addition, the PartsDecodedString property will be populated with the string representation of the decoded data.

Example. Decoding a Specified Part: mime.MessageHeadersString = myMessageHeaders; mime.Message = myMessageBody; mime.DecodeFromString(); byte[] myPartContent = await mime.DecodePart(0);

MIME.decodePartToFile Method

This method decodes the specified part to a file on disk.

Syntax

async mime.decodePartToFile(index : number): Promise<string>

Remarks

This method decodes the part specified by Index to a temporary file. The full path to the temporary file is returned by this method. The user is responsible for deleting the temporary file.

DecodeFromString or DecodeFromFile must be called before calling this method.

MIME.encodeToFile Method

This method encodes to a file.

Syntax

async mime.encodeToFile(): Promise<void>

Remarks

This method encodes the data given in Parts properties (either a decoded file or a decoded string) into a MIME message at Message and MessageHeaders using the values optionally given in Parts properties. To encode several objects into a MIME envelope, the user should first clear any old values left in the Parts properties.

The class will check for each item in Parts properties (first the decoded file and then the decoded string) for the data to encode.

The encoded message will be saved in the file pointed to by Message; the message headers will be held by MessageHeaders.

Example. Encoding Data:

MIMEControl.ResetData() MIMEControl.PartCount = 2 MIMEControl.PartDecodedString(0) = "This is plain text data" MIMEControl.PartEncoding(0) = peQuotedPrintable MIMEControl.PartContentType(0) = "text/plain" MIMEControl.PartDecodedFile(1) = "C:\filename.txt" MIMEControl.Message = "temp.tmp" MIMEControl.EncodeToFile()

MIME.encodeToString Method

This method encodes to a string.

Syntax

async mime.encodeToString(): Promise<void>

Remarks

This method encodes to a string. It is the same as EncodeToFile but the encoded data are held in the Message property rather than saved to a file.

This method encodes the data given in the Parts properties into a MIME message. The message gets stored in Message and MessageHeaders using the values optionally given in Parts properties. To encode several objects into a MIME envelope, the user should first clear any old values left in the Parts properties by calling ResetData.

The class will check each item in the Parts properties (first the decoded file and then the decoded string) for the data to encode.

The encoded message will be stored in the Message property; the message headers will be held by MessageHeaders.

Example. Encoding Data:

MIMEControl.ResetData() MIMEControl.PartCount = 2 MIMEControl.PartDecodedString(0) = "This is plain text data" MIMEControl.PartEncoding(0) = peQuotedPrintable MIMEControl.PartContentType(0) = "text/plain" MIMEControl.PartDecodedFile(1) = "C:\filename.txt" MIMEControl.EncodeToString()

MIME.reset Method

This method will reset the class.

Syntax

async mime.reset(): Promise<void>

Remarks

This method will reset the class's properties to their default values.

MIME.resetData Method

This method resets the values of all headers and part properties.

Syntax

async mime.resetData(): Promise<void>

Remarks

This method resets the values of all headers and part properties. It is an easy way to reset the class's properties before starting to populate the part properties with new values.

MIME.Error Event

Fired when information is available about errors during data delivery.

Syntax

mime.on('Error', listener: (e: {readonly errorCode: number, readonly description: string}) => void )

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class .

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

MIME.Header Event

This event is fired every time a header is parsed.

Syntax

mime.on('Header', listener: (e: {readonly partIndex: number, readonly field: string, readonly value: string, readonly valueB: Uint8Array}) => void )

Remarks

The PartIndex parameter contains the index of the part containing the current header. If the header is from the MIME body, this value will be -1. The Field parameter contains the name of the MIME header. The Value parameter contains the header contents. The Header event is fired when a header is parsed, which occurs for each header of the message when DecodeFromFile, DecodeFromString, or DecodeFromStream is called.

MIME.Progress Event

This event shows the progress of decoding or encoding the input data.

Syntax

mime.on('Progress', listener: (e: {readonly percentDone: number}) => void )

Remarks

The Progress allows the user to visualize the progress of processing the input data.

The PercentDone parameter shows what percentage of the input has been read.

Header Type

This is an HTTP header as it is received from the server.

Remarks

When a header is received through a Header event, it is parsed into a Header type. This type contains a , and its corresponding .

The following fields are available:

Fields

Field
string

Default Value: ""

This property contains the name of the HTTP Header (this is the same case as it is delivered).

Value
string

Default Value: ""

This property contains the Header contents.

Constructors

public Header();
public Header(String field, String value);

MIMEPart Type

This is a part of the MIME message.

Remarks

Each MIME message is split into parts. A message must have at least one part to be a valid MIME message. The message itself is split into the MessageHeaders and the Message body. The body is then split into MIME parts by a specified or generated Boundary. Each part of a MIME message has its own as well. These headers describe the MIMEPart and its contents.

The decoded data will be held in or otherwise will be saved in a temporary file given by when the user asks for the value of the respective field.

If the encoded data are file data, the decoded file(s) will be given in the field. Otherwise, the decoded data will be in the field.

When the EncodeToString method is called, the class will check for each item in the Parts properties (first the and then the ) for the data to encode.

The following fields are available:

Fields

ContentDisposition
string

Default Value: ""

This property contains content disposition for each part.

The value in this property is used in the Content-Disposition header. Typical values include "form-data" and "attachment". The class fills it out each time the is changed. Changing the recalculates the as well.

ContentDispositionAttr
string

Default Value: ""

This property contains the content disposition's attribute (if any) for each part.

Typical values for this property are the names of the form-variables used while creating an HTTP post or the values for filenames.

Setting this property recalculates the .

ContentId
string

Default Value: ""

This property contains the content identifier for each part. The value of this property is used in the Content-Id header. The class fills it out each time the is changed. Changing this property recalculates the as well.

ContentType
string

Default Value: ""

string

Default Value: ""

This property holds the actual content of each part. The class decodes the actual part of Message to when 's value is first queried.

Setting a value to fills out the corresponding with the string size if the corresponding is empty.

The class checks during encoding first : if it is empty, then the class uses the value of .

Note: It is recommended to use the DecodePart method instead of querying this property.

DecodedStringB
Uint8Array

Default Value: ""

This property holds the actual content of each part. The class decodes the actual part of Message to when 's value is first queried.

Setting a value to fills out the corresponding with the string size if the corresponding is empty.

During decoding, this property is filled with the size of that part.

Constructors

public MIMEPart();
public MIMEPart(String decodedFile);
public MIMEPart(byte[] decodedString);

Config Settings (class ipworkssmime.mime)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

MIME Config Settings

DecodeMessageHeaders:   Instructs the component to automatically decode message headers.

Message headers that have been Quoted-Printable or Base64 encoded are automatically decoded when this configuration setting is True. The default value of this setting is False.

IncludeHeaders:   Tells the class whether to include the headers when encoding the message.

If True, the class will include the headers when EncodeToFile or EncodeToString are called. If False, only the message will be encoded.

The default value for IncludeHeaders is False.

RequireVersionHeader:   Specifies whether or not the class should require the version header.

If True, the class will require that the "MIME-Version" header be included in the MessageHeaders. If the header is not present during decoding, the component . This configuration setting is False by default.

SanitizeFileName:   Whether invalid characters are replaced in MIME part filenames.

If True, the class will replace invalid characters with an underscore when decoding the MIME message. This applies to the filename held in the PartsFileName property. When True, the following characters are considered invalid:

  • \
  • /
  • "
  • :
  • ?
  • *
  • <
  • >
  • |
Any characters with ASCII values between 0 and 31 are also considered invalid. The default value is False.
TempFilePath:   If set, the temporary files created during MIME decoding and encoding will be put in the path specified.

The TempFilePath property sets the path at which the temporary files will be created.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).
