\membersection{wxHTTP::GetResponse}\label{wxhttpgetresponse}
|
|
|
|
\constfunc{int}{GetResponse}{\void}
|
|
|
|
Returns the HTTP response code returned by the server. Please refer to the RFC
|
|
2616 for the list of the responses.
|
|
|
|
|
|
\membersection{wxHTTP::GetInputStream}\label{wxhttpgetinputstream}
|
|
|
|
\func{wxInputStream *}{GetInputStream}{\param{const wxString\&}{ path}}
|
|
|
|
Creates a new input stream on the specified path. You can use all except the seek
|
|
functionality of wxStream. Seek isn't available on all streams. For example,
|
|
http or ftp streams doesn't deal with it. Other functions like Tell and SeekI
|
|
for this sort of stream.
|
|
You will be notified when the EOF is reached by an error.
|
|
|
|
\wxheading{Note}
|
|
|
|
You can know the size of the file you are getting using \helpref{wxStreamBase::GetSize()}{wxstreambasegetsize}.
|
|
But there is a limitation: as HTTP servers aren't obliged to pass the size of
|
|
the file, in some case, you will be returned 0xfffffff by GetSize(). In these
|
|
cases, you should use the value returned by \helpref{wxInputStream::LastRead()}{wxinputstreamlastread}:
|
|
this value will be 0 when the stream is finished.
|
|
|
|
\wxheading{Return value}
|
|
|
|
Returns the initialized stream. You will have to delete it yourself once you
|
|
don't use it anymore. The destructor closes the network connection.
|
|
The next time you will try to get a file the network connection will have
|
|
to be reestablished: but you don't have to take care of this wxHTTP reestablishes it automatically.

\membersection{wxHTTP::SetHeader}\label{wxhttpsetheader}
|
|
|
|
\func{void}{SetHeader}{\param{const wxString\&}{ header}, \param{const wxString\&}{ h\_data}}
|
|
|
|
It sets data of a field to be sent during the next request to the HTTP server. The field
|
|
name is specified by {\it header} and the content by {\it h\_data}.
|
|
This is a low level function and it assumes that you know what you are doing.
|
|
|
|
\membersection{wxHTTP::GetHeader}\label{wxhttpgetheader}
|
|
|
|
\func{wxString}{GetHeader}{\param{const wxString\&}{ header}}
|
|
|
|
Returns the data attached with a field whose name is specified by {\it header}.
|
|
If the field doesn't exist, it will return an empty string and not a NULL string.
|
|
|
|
\wxheading{Note}
|
|
|
|
The header is not case-sensitive: I mean that "CONTENT-TYPE" and "content-type"
|
|
represent the same header.
