RWIHttpClient is deprecated and has been replaced by RWHttpClient. Changes were necessary to take advantage of new features in HTTP/1.1:
The RWIHttpVersion class is no longer necessary. Information concerning how a request should be sent is stored in the RWHttpRequest class, not in the client itself.
Executing a request is a two-step process. RWIHttpClient sends a request and retrieves the reply using a single member function. RWHttpClient splits the function into two member functions.
RWIHttpClient returns an RWIHttpReply instance wrapped in an IOU, and automatically spawns a thread in order to execute the request. RWHttpClient is no longer multithread-hot, so the IOU is no longer in the return. This adds flexibility in determining when RWHttpClient requests need their own threads and how those threads are organized.
The following examples show a request for the root document of the www.roguewave.com Web server using RWIHttpClient and RWHttpClient. They are simple, but will help you to convert larger requests to the RWHttpClient.
RWIHttpVersion_1_0 httpVersion;
RWIHttpClient client(httpVersion);
RWTIOUResult<RWIHttpReply> iouReply;
client.connect("www.roguewave.com");
RWIHttpGet getRequest("/");
iouReply = client.execute(getRequest);
RWIHttpReply reply = iouReply.redeem();
RWSocketPortal portal = reply.portal();
RWCString body, temp;
while (!(temp = portal.recv()).isNull())
body += temp;
|
RWHttpClient client = RWHttpSocketClient::make();
client.connect("www.roguewave.com");
RWHttpRequest getRequest(RWHttpRequest::Get, "/");
client.submit(getRequest);
RWHttpReply reply = client.getReply();
RWCString body = reply.getBody();
