QgsBufferServerResponse

Class defining buffered response

class qgis.server.QgsServerResponse

class qgis.server.QgsServerResponse(a0: QgsServerResponse)

Bases: object

clear(self)

Reset all headers and content for this response

data(self) → QByteArray

Gets the data written so far

This is implementation dependent: some implementations may not give access to the underlying and return an empty array.

Note that each call to ‘flush’ may empty the buffer and in case of streaming process you may get partial content

Return type:

QByteArray

feedback(self) → QgsFeedback | None

Returns the socket feedback if any

Added in version 3.36.

Return type:

Optional[QgsFeedback]

finish(self)

Finish the response, ending the transaction. The default implementation does nothing.

flush(self)

Flushes the current output buffer to the network

‘flush()’ may be called multiple times. For HTTP transactions headers will be written on the first call to ‘flush()’. The default implementation does nothing.

header(self, key: str | None) → str

Returns the header value

Parameters:

key (Optional[str])

Return type:

str

headers(self) → Dict[str, str]

Returns the header value

Return type:

Dict[str, str]

headersSent(self) → bool

Returns True if the headers have already been sent

Return type:

bool

io(self) → QIODevice | None

Returns the underlying QIODevice

Return type:

Optional[QIODevice]

removeHeader(self, key: str | None)

Clear header Undo a previous ‘setHeader’ call

Parameters:

key (Optional[str])

sendError(self, code: int, message: str | None)

Send error This method delegates error handling at the server level. This is different from calling setReturnCode() which let you return a specific response body. Calling sendError() will end the transaction and any attempt to write data or set headers will be an error.

Parameters:

• code (int) – HHTP return code value

• message (Optional[str]) – An informative error message

setHeader(self, key: str | None, value: str | None)

Set Header entry Add Header entry to the response Note that it is usually an error to set Header after data have been sent through the wire

Parameters:

• key (Optional[str])

• value (Optional[str])

setStatusCode(self, code: int)

Set the http status code

Parameters:

code (int) – HTTP status code value

statusCode(self) → int

Returns the http status code

Return type:

int

truncate(self)

Truncate data

Clear internal buffer

write(self, data: str | None)

Write string This is a convenient method that will write directly to the underlying I/O device

write(self, byteArray: Union[QByteArray, bytes, bytearray]) -> int Write chunk of data This is a convenient method that will write directly to the underlying I/O device

Returns:

the number of bytes that were actually written

write(self, ex: QgsServerException) Write server exception

Parameters:

data (Optional[str])
