• extract_content_type -- Whether to extract the content type and any options.

• extract_cookies -- Whether to extract cookies.

• extract_headers -- Whether to extract headers.

• extract_method -- Whether to extract the HTTP method, (for requests only).

• extract_path -- Whether to extract the path.

• extract_path_params -- Whether to extract path parameters.

• extract_query -- Whether to extract query parameters.

• extract_scheme -- Whether to extract the http scheme.

• obfuscate_headers -- headers keys to obfuscate. Obfuscated values are replaced with '*'.

• obfuscate_cookies -- cookie keys to obfuscate. Obfuscated values are replaced with '*'.

• parse_body -- Whether to parse the body value or return the raw byte string, (for requests only).

• parse_query -- Whether to parse query parameters or return the raw byte string.

• skip_parse_malformed_body -- Whether to skip parsing the body if it is malformed

__call__(connection: ASGIConnection[Any, Any, Any, Any]) → ExtractedRequestData

Extract data from the connection, returning a dictionary of values.

备注

• The value for body - if present - is an unresolved Coroutine and as such should be awaited by the receiver.

返回:

The connection's scope["path"] value

extract_headers(connection: ASGIConnection[Any, Any, Any, Any]) → dict[str, str]

Extract headers from an ASGIConnection

参数:

connection -- An ASGIConnection instance.

返回:

A dictionary with the connection's headers.

extract_cookies(connection: ASGIConnection[Any, Any, Any, Any]) → dict[str, str]

参数:

connection -- An ASGIConnection instance.

返回:

A dictionary with the connection's path parameters.

参数:

request -- A Request instance.

返回:

A tuple containing the request's parsed 'Content-Type' header.

async extract_body(request: Request[Any, Any, Any]) → Any
