Public Member Functions

 HttpRequest (const String &url, const String &verb, const Vector< String > &headers, const String &postData)
 Construct with parameters.
 
virtual ~HttpRequest () override
 Destruct. Release the connection object.
 
virtual void ThreadFunction () override
 Process the connection in the worker thread until closed. More...
 
virtual unsigned Read (void *dest, unsigned size) override
 Read response data from the HTTP connection and return number of bytes actually read. While the connection is open, will block while trying to read the specified size. To avoid blocking, only read up to as many bytes as GetAvailableSize() returns.
 
virtual unsigned Seek (unsigned position) override
 Set position from the beginning of the stream. Not supported.
 
virtual bool IsEof () const override
 Return whether all response data has been read.
 
const StringGetURL () const
 Return URL used in the request.
 
const StringGetVerb () const
 Return verb used in the request. Default GET if empty verb specified on construction.
 
String GetError () const
 Return error. Only non-empty in the error state.
 
HttpRequestState GetState () const
 Return connection state.
 
unsigned GetAvailableSize () const
 Return amount of bytes in the read buffer.
 
bool IsOpen () const
 Return whether connection is in the open state.

 Increment reference count. Can also be called outside of a SharedPtr for traditional reference counting.
 
void ReleaseRef ()
 Decrement reference count and delete self if no more references. Can also be called outside of a SharedPtr for traditional reference counting.
