发出http post请求以在WP7中发送JSON文件
我想JSON file from my WP7 device to my local server发送一个JSON file from my WP7 device to my local server 。 在iOS上，我使用了ASIHttpRequest库，我所做的是：
//send json file , using ASIHttpClass NSURL *url = [NSURL URLWithString:urlStr]; ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; request.timeOutSeconds = TIME_OUT_SECONDS; [request setRequestMethod:@"PUT"]; NSString *credentials= [self encodeCredentials]; [request addRequestHeader:@"Authorization" value:[[NSString alloc] initWithFormat:@"Basic %@",credentials]]; [request addRequestHeader:@"Content-Type" value:@"application/json; charset=utf-8"]; [request appendPostData:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; [request startSynchronous]; if([request responseStatusCode]==200){ return true; } else { return false; }
我如何在WP7应用程序中实现相同的function？
到目前为止我发现了什么，我认为我很接近：
//Making a POST request using WebClient. Function() { WebClient wc = new WebClient(); var URI = new Uri("http://your_uri_goes_here"); wc.Headers["Authorization"] = "Basic (here goes my credentials string which i have)"; wc.Headers["Content-Type"] = "application/json; charset=utf-8"; wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc_UploadStringCompleted); wc_cart_session.UploadStringAsync(URI,"POST","Data_To_Be_sent"); }
其中：
void wc__UploadStringCompleted(object sender, UploadStringCompletedEventArgs e) { try { MessageBox.Show(e.Result); //e.result fetches you the response against your POST request. } catch(Exception exc) { MessageBox.Show(exc.ToString()); } }
我想“Data_to_be_Sent”应该是utf8编码中的jsonString？
编辑
我注意到"Data_To_Be_sent"是一个字符串。 但是这应该是UTF8编码吗？ 所以它应该是一个UTF8格式的字节数组。 但是我只能在那里放一根绳子。 我在这里缺少什么？
WebClient类具有UploadStringAsync和DownloadStringAsync方法使用的Encoding属性。 在那里设置你的编码。
wc.Encoding = Encoding.UTF8; wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc_UploadStringCompleted); wc.UploadStringAsync(URI,"POST","Data_To_Be_sent");
