如何在Windows Phone中發送/發佈JSON請求

Question

任何人都知道如何在windowsphone中使用JSON內容發送請求。我有JSON參數如何發佈。

Answer 1

簡單地使用JSON序列化數據，並將其作爲POST請求寫入服務器。以下是我在其中一個應用中執行的操作：

private static IObservable<T> GetDataAsync<T, TRequest>(TRequest input, string address) 
{ 
    var request = HttpWebRequest.Create(address); 
    request.Method = "POST"; 

    var getRequestStream = Observable.FromAsyncPattern<Stream>(
     request.BeginGetRequestStream, 
     request.EndGetRequestStream); 

    var getResponse = Observable.FromAsyncPattern<WebResponse>(
     request.BeginGetResponse, 
     request.EndGetResponse); 

    return getRequestStream() 
       .SelectMany(stream => 
       { 
        try 
        { 
         using (var writer = new StreamWriter(stream)) 
          writer.WriteLine(JsonConvert.SerializeObject(input)); 
        } 
        catch 
        { 
         // Intentionally ignored. 
        } 

        return getResponse(); 
       }) 
       .Select(webResponse => 
       { 
        using (var reader = new StreamReader(webResponse.GetResponseStream())) 
         return JsonConvert.DeserializeObject<T>(reader.ReadToEnd()); 
       }); 
}
