Send-WebDAV Cmdlet

Parameters   Output Objects   Config Settings  

The Send-WebDAV component implements an easy-to-use interface to the Web Distributed Authoring and Versioning protocol (WebDAV).

Syntax

Send-WebDAV [parameters]

Remarks

The cmdlet allows the adding new resources and posting data to existing resources.

Depth is used to determine how the properties are retrieved. A depth of "0" will return only the properties associated with ResourceURI. A depth of "1" will return those properties, plus those of the member URIs. A depth of "infinity" (default) will return all properties of all the resources in the hierarchy.

The cmdlets support pipeline input for some of their parameters. Prebuilding an object and piping it to the cmdlet is very useful, but should be used with caution to prevent security conflicts. Steps have been taken to decrease the risk of a possibly accidental pipe to the cmdlet, for instance, the Credential parameter cannot be piped to the cmdlet and must be specified manually.

# create a new resource at http://localhost/temp/test.html send-webdav -uri http://localhost/temp/ -localfile C:\test.html -method put # create a new resource at http://localhost/test1.html send-webdav -uri http://localhost/test1.html -localfile C:\test.html -method put # post data to an existing resource send-webdav -uri http://localhost/temp -data $data -method post

Parameter Alias

CertificatePassword

CertStore Property (Send-WebDAV Cmdlet)

The name of the certificate store for the client certificate.

Syntax

Send-WebDAV -CertStore string

Remarks

The CertStoreType parameter specifies the type of the certificate store specified by CertStore. If the store is password protected, specify the password in CertPassword.

CertStore is used in conjunction with the CertSubject parameter in order to specify client certificates. If CertStore has a value, and CertSubject has been set, a search for a certificate is initiated during logon. Please refer to the CertSubject parameter for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this parameter must be set to the name of the file.

Default Value

"MY"

Parameter Alias

CertificateStore

CertStoreType Property (Send-WebDAV Cmdlet)

The type of certificate store for the client certificate.

Syntax

Send-WebDAV -CertStoreType string

Remarks

This parameter can take one of the following values:

User (default)This specifies that the certificate store is owned by the current user (these are the user's registry certificate stores such as MY, CA, etc.).
MachineThe certificate store is a machine store.
PFXFileThe certificate store is the name of a PFX (PKCS12) file containing certificates.
PFXBlobThe certificate store is a string (base64 encoded) representing a certificate store in PFX (PKCS12) format. You should use this option if storing a pfx file's content in a shell variable.

CertSubject Property (Send-WebDAV Cmdlet)

The subject of the certificate used for client authentication.

Syntax

Send-WebDAV -CertSubject string

Remarks

During the user authentication phase of the logon process, the cmdlet will search the store specified in CertStore for a certificate that matches this parameter. If the store contains a private key for that certificate, it is used to verify the user's identity with the secure server.

When this parameter is set, a search is performed in the current certificate store certificate with matching subject.

If an exact match is not found, the store is searched for subjects containing the value of the parameter.

When setting the parameter to a partial subject, CN= should be omitted. For example, the following code would find the certificate with subject CN=Test Certificate, OU=People, C=US

Example (Searching with partial subject)

-certsubject "Test"

If a match is not found, the parameter is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

Default Value

"*"

Config Property (Send-WebDAV Cmdlet)

Specifies one or more configuration settings.

Credential Property (Send-WebDAV Cmdlet)

The PSCredential object to use for user/password authentication.

Syntax

Send-WebDAV -Credential PSCredential

Remarks

Every cmdlet that supports user authentication will expose a Credential parameter. A PSCredential object should be specified for this parameter. Alternatively, the User and Password parameters can be set to represent the credential information.

If the cmdlet supports client key authentication it uses the password field of this object for the certificate's password. This setting is enabled by using public key authentication. Note: Due to security reasons, it is recommended that you use the Credential parameter rather than User and Password to specify the authentication information.

Default Value

null

ProxyUser Property (Send-WebDAV Cmdlet)

The User value to authenticate with.

Syntax

Send-WebDAV -ProxyUser string

Remarks

If authentication is required with the proxy server, the ProxyUser parameter specifies the username.

Default Value

""

SSLAccept Property (Send-WebDAV Cmdlet)

The encoded public key of the certificate which is to be trusted explicitly.

Syntax

Send-WebDAV -SSLAccept string

Remarks

Ordinarily, the certificate presented by the server will be checked against the system certificate stores to see if the Certificate Authority is trusted, and if not, the cmdlet will prompt the user to accept the certificate. Setting this parameter will override the system settings and trust the certificate provided.

After each connection, regardless of whether or not the certificate was trusted, the cmdlet will store the certificate presented by the server in the $SSLServerCertificate session variable. This variable can be inspected to view details of the server's certificate.

If the Force parameter is set, the cmdlet will accept the server's certificate unconditionally.

In cases where the certificate presented by the server is not trusted, a prompt will be shown to the user. This prompt will allow the user to decide whether or not they would like to accept the certificate presented by the server.

There may be cases where you do not want a prompt to be displayed or would like to handle the response supplied directly within your script. This can be done by setting the $SSLAcceptPreference variable prior to running the cmdlet. The available values for this variable are:

None (default)Maintains the default behavior. If the certificate is not trusted by default, the user will be prompted.
AcceptAccepts the certificate without prompting the user, even if it is not trusted by default.
RejectRejects the certificate without prompting the user only if it is not trusted by default. Thus if the certificate is found to be trusted or the Force parameter is set, the connection will still be accepted.

Default Value

""

Parameter Alias

Accept

Timeout Property (Send-WebDAV Cmdlet)

The maximum time allowed for the operation.

Syntax

Send-WebDAV -Timeout int

Send-WebDAV -URI string

Remarks

The cmdlet will use this URI for all operations on the webdav server.

Default Value

""

Parameter Position

0

Parameter Alias

URL

This is a required parameter.

User Property (Send-WebDAV Cmdlet)

The username to use for authentication.

Syntax

Send-WebDAV -User string

Remarks

Every time User and Password are set, the cmdlet will authenticate with the server. It is recommended that the Credential parameter is set instead of User/Password because of security reasons. If both Credential and this parameter is set, the Credential value is used.

Default Value

""

DAVFile Output Object (Send-WebDAV Cmdlet)

This object is created after a file has finished transferring.

Syntax

Object DAVFile {
   string URI;
   int Time;
   string Text;
}

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a cmdlet is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these cmdlets: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Tells the cmdlet whether or not to use the system security libraries or an internal implementation.

When set to false, the cmdlet will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments this is not desirable. To use a completely managed security implementation set this setting to true.

Setting this setting to true tells the cmdlet to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all cmdlets used in the application.

When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.
