Public Member Functions

 HttpRequest (const String &url, const String &verb, const Vector< String > &headers, const String &postData)
 Construct with parameters.
 
 ~HttpRequest () override
 Destruct. Release the connection object.
 
void ThreadFunction () override
 Process the connection in the worker thread until closed. More...
 
i32 Read (void *dest, i32 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. More...
 
i64 Seek (i64 position) override
 Set position from the beginning of the stream. Not supported. More...
 
bool IsEof () const override
 Return whether all response data has been read. More...
 
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.
 
i32 GetAvailableSize () const
 Return amount of bytes in the read buffer.
 
bool IsOpen () const

An HTTP connection with response data stream.

Member Function Documentation

◆ IsEof()

bool Urho3D::HttpRequest::IsEof ( ) const
overridevirtual

Return whether all response data has been read.

Reimplemented from Urho3D::Deserializer.

◆ Read()

i32 Urho3D::HttpRequest::Read ( void *  dest,
i32  size 
)
overridevirtual

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.

Implements Urho3D::Deserializer.

◆ Seek()

i64 Urho3D::HttpRequest::Seek ( i64  position)
overridevirtual
