我想要一个JSON对象发送到我的web服务的方法，该方法是这样定义的：
公共字符串SendTransaction（串反）
{
VAR json_serializer =新JavaScriptSerializer（）;
交易transObj = json_serializer.Deserialize＆其中;交易＆GT;（反式）;
返回transObj.FileName;
}
在哪里我想回到我得到作为参数此JSON字符串的文件名。
在code的Android应用程序：
HttpPost请求=新HttpPost（
http://10.118.18.88:8080/Service.svc/SendTransaction）;
request.setHeader（接受，应用/ JSON）;
request.setHeader（内容型，应用/ JSON）;
//构建JSON字符串
JSONStringer jsonString;
jsonString =新JSONStringer（）
.object（）键（IMEI）。值（2323232323）。键（文件名）
.value的（Finger.NST）endObject（）。
Log.i（JSON字符串：，jsonString.toString（））;
StringEntity实体;
实体=新StringEntity（jsonString.toString（），UTF-8）;
entity.setContentEncoding（新BasicHeader（HTTP.CONTENT_TYPE，
应用/ JSON））;
entity.setContentType（应用/ JSON）;
request.setEntity（实体）;
//发送请求WCF服务
DefaultHttpClient的HttpClient =新DefaultHttpClient（）;
HTT presponse响应= httpClient.execute（要求）;
HttpEntity httpEntity = response.getEntity（）;
XML字符串= EntityUtils.toString（httpEntity）;
Log.i（回应：XML）;
Log.d（WebInvoke，状态：+ response.getStatusLine（））;
我只得到很长的HTML文件了，还告诉我服务器遇到了错误处理请求。并且状态code是 HTTP / 1.1 400错误的请求
我的交易类在C＃中这样定义的：
[DataContract]
公共类交易
{
[数据成员（NAME =IMEI）
公共字符串维明{获得;组; }
[数据成员（名称为文件名）]
公共字符串文件名{获得;组; }
}
我怎样才能做到这一点的方法不对？

@Tobias，这是不是一个答案。但是，由于这是一个有点长的评论，我在这里张贴。也许这可以帮助诊断问题。 [一个完整的工作code]。的

I'm trying to send a JSON object to my webservice method, the method is defined like this:
public String SendTransaction(string trans)
{
var json_serializer = new JavaScriptSerializer();
Transaction transObj = json_serializer.Deserialize<Transaction>(trans);
return transObj.FileName;
}
Where I want to return the FileName of this JSON string that I got as a parameter.
The code for the android application:
HttpPost request = new HttpPost(
"http://10.118.18.88:8080/Service.svc/SendTransaction");
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
// Build JSON string
JSONStringer jsonString;
jsonString = new JSONStringer()
.object().key("imei").value("2323232323").key("filename")
.value("Finger.NST").endObject();
Log.i("JSON STRING: ", jsonString.toString());
StringEntity entity;
entity = new StringEntity(jsonString.toString(), "UTF-8");
entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,
"application/json"));
entity.setContentType("application/json");
request.setEntity(entity);
// Send request to WCF service
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
HttpEntity httpEntity = response.getEntity();
String xml = EntityUtils.toString(httpEntity);
Log.i("Response: ", xml);
Log.d("WebInvoke", "Status : " + response.getStatusLine());
I only get a long html file out, which tells me The server has encountered an error processing the request. And the status code is HTTP/1.1 400 Bad Request
My Transaction class is defined in C# like this:
[DataContract]
public class Transaction
{
[DataMember(Name ="imei")]
public string Imei { get; set; }
[DataMember (Name="filename")]
public string FileName { get; set; }
}
How can I accomplish this in the right way?
EDIT, this is my web.config
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>

@Tobias, This is not an answer. But since it was a little bit long for comment, I post it here. Maybe it can help to diagnose your problem. [A full working code].
public void TestWCFService()
{
//Start Server
Task.Factory.StartNew(
(_) =>{
Uri baseAddress = new Uri("http://localhost:8080/Test");
WebServiceHost host = new WebServiceHost(typeof(TestService), baseAddress);
host.Open();
},null,TaskCreationOptions.LongRunning).Wait();
//Client
var jsonString = new JavaScriptSerializer().Serialize(new { xaction = new { Imei = "121212", FileName = "Finger.NST" } });
WebClient wc = new WebClient();
wc.Headers.Add("Content-Type", "application/json");
var result = wc.UploadString("http://localhost:8080/Test/Hello", jsonString);
}
[ServiceContract]
public class TestService
{
[OperationContract]
[WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
public User Hello(Transaction xaction)
{
return new User() { Id = 1, Name = "Joe", Xaction = xaction };
}
public class User
{
public int Id { get; set; }
public string Name { get; set; }
public Transaction Xaction { get; set; }
}
public class Transaction
{
public string Imei { get; set; }
public string FileName { get; set; }
}
}
