我无法将值的 JSONArray 发布到我的 WCF 服务。当我从 Fiddler 或 .Net Test Client 发布数据时，它工作正常。每次我尝试从我的 android 应用程序发布时，我都会收到请求错误
这是我从 android 应用程序发送到我的 WCF 服务的 JSON 数据。我已经尝试了来自 Fiddler 的确切数据并且它有效
[{"date":"2013-02-22 15:30:374:021","id":"1","description":"test","name":"test"},
"date":"2013-02-25 11:56:926:020","id":"2","description":"ghy","name":"fhh"},
"date":"2013-02-25 11:56:248:026","id":"3","description":"ghfm","name":"run"}]
我的安卓代码
public JSONObject makeHttpPost(String url, String method, JSONArray params) {
try {
if (method == "POST") {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-Type",
"application/json; charset=utf-8");
StringEntity se = new StringEntity(params.toString(),"UTF-8");
se.setContentType("application/json;charset=UTF-8");
httpPost.setEntity(se);
Log.e("Gerhard", params.toString());
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
我的 WCF 服务
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "updateOrderAddress")]
String UpdateOrderAddress(Stream JSONdataStream);
public String UpdateOrderAddress(Stream JSONdataStream)
{
try
{
// Read in our Stream into a string...
StreamReader reader = new StreamReader(JSONdataStream);
string JSONdata = reader.ReadToEnd();
// ..then convert the string into a single "wsOrder" record.
if (JSONdata == null)
{
// Error: Couldn't deserialize our JSON string into a "wsOrder" object.
return "null";
}
return JSONdata; // Success !
}
catch (Exception e)
{
return e.ToString();
}
}
我得到的错误
02-26 14:00:56.185: E/Gerhard(31064): <p>The server encountered an error processing the request. The exception message is 'Incoming message for operation 'UpdateOrderAddress' (contract 'IService1' with namespace 'http://tempuri.org/') contains an unrecognized http body format value 'Json'. The expected body format value is 'Raw'. This can be because a WebContentTypeMapper has not been configured on the binding. See the documentation of WebContentTypeMapper for more details.'.

我已经从 android 应用程序向同一个 WCF 服务调用了多个 GET 请求并且它工作得很好，但现在我需要将一组数据发送到 wcf 服务。请帮助我。提前致谢
最佳答案
删除
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-Type", "application/json; charset=utf-8");
