on_header Event

Fired every time a header line comes in.

Syntax

class S3ClientHeaderEventParams(object):
  @property
  def field() -> str: ...
  @property
  def value() -> str: ...

# In class S3Client:
@property
def on_header() -> Callable[[S3ClientHeaderEventParams], None]: ...
@on_header.setter
def on_header(event_hook: Callable[[S3ClientHeaderEventParams], None]) -> None: ...

Remarks

The Field parameter contains the name of the HTTP header (same case as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).
