Member Function Documentation▲
QHttpServerResponder::QHttpServerResponder(QHttpServerResponder &&other)▲
Move-constructs a QHttpServerResponder instance, making it point at the same object that other was pointing to.
QHttpServerResponder::~QHttpServerResponder()▲
Destroys a QHttpServerResponder.
void QHttpServerResponder::write(QIODevice *data, QHttpServerResponder::HeaderList headers, QHttpServerResponder::StatusCode status = StatusCode::Ok)▲
Answers a request with an HTTP status code status and HTTP headers headers. The I/O device data provides the body of the response. If data is sequential, the body of the message is sent in chunks: otherwise, the function assumes all the content is available and sends it all at once but the read is done in chunks.
This function takes the ownership of data.
void QHttpServerResponder::write(QIODevice *data, const QByteArray &mimeType, QHttpServerResponder::StatusCode status = StatusCode::Ok)▲
Answers a request with an HTTP status code status and a MIME type mimeType. The I/O device data provides the body of the response. If data is sequential, the body of the message is sent in chunks: otherwise, the function assumes all the content is available and sends it all at once but the read is done in chunks.
