symbian 使用http get post方式获取网页信息

核心提示：void CClientEngine::IssueHTTPGetL(const TDesC8& aUri)//以get方式获取一个网页 { SetupConnectionL(); // Parse string to URI (as defined in RFC2396) TUriParser8 uri; uri.Pa

void CClientEngine::IssueHTTPGetL(const TDesC8& aUri)//以get方式获取一个网页 { SetupConnectionL(); // Parse string to URI (as defined in RFC2396) TUriParser8 uri; uri.Parse(aUri);//把传入的uri转化为标准格式 // Get request method string for HTTP GET RStringF method = iSession.StringPool().StringF(HTTP::EGET, RHTTPSession::GetTable());//设置以get的方法读取 // Open transaction with previous method and parsed uri. This class will // receive transaction events in MHFRunL and MHFRunError. iTransaction = iSession.OpenTransactionL(uri, *this, method);//打开一个连接 使用设置好的方法和指定的uri // Set headers for request; user agent and accepted content type RHTTPHeaders hdr = iTransaction.Request().GetHeaderCollection();//设置一个http头 SetHeaderL(hdr, HTTP::EUserAgent, KUserAgent); SetHeaderL(hdr, HTTP::EAccept, KAccept); // Submit the transaction.
