Android向Rest服务Post数据遇到的Date类型数据问题

  今天在Android端向Rest服务Post数据时,总是不成功,查了很多资料,才知道Rest端将json串反序列化时,需要的时间格式必须是UTC类型,及Date(12345678+0800)格式。

Android端序列化方法 

//利用Gson实现对象序列化为Json
public static String toJson(Object object) {
  GsonBuilder builder = new GsonBuilder();
  // 不转换没有 @Expose 注解的字段
  builder.excludeFieldsWithoutExposeAnnotation();   //对Date类型进行注册事件   builder.registerTypeAdapter(Date.class, new UtilDateSerializer());   Gson gson = builder.create();   return gson.toJson(object); } class UtilDateSerializer implements JsonSerializer<Date> {   @Override   public JsonElement serialize(Date src, Type typeOfSrc,    JsonSerializationContext context) {     //拼凑UTC时间类型
    return new JsonPrimitive("/Date(" + src.getTime()+ "+0800)/");   } }

Android端Post方法

/**
 * 通过POST方式发送请求
* 
 * @param url
*            URL地址
* @param params
*            参数
* @return
* @throws Exception
 */
public String httpPost(String url, String json) throws Exception {
  String response = null;
  int timeoutConnection = 3000;
  int timeoutSocket = 5000;
  HttpParams httpParameters = new BasicHttpParams();
  HttpConnectionParams.setConnectionTimeout(httpParameters,timeoutConnection);
  HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
  HttpClient httpClient
= new DefaultHttpClient(httpParameters);
  HttpPost httpPost
= new HttpPost(url); // 添加http头信息
  httpPost.addHeader("Content-Type", "application/json");
  httpPost.addHeader(
"User-Agent", "imgfornote");
  httpPost.setEntity(
new StringEntity(json,"UTF-8"));
  HttpResponse httpResponse
= httpClient.execute(httpPost);   int statusCode = httpResponse.getStatusLine().getStatusCode();   if (statusCode == HttpStatus.SC_OK) {   response = EntityUtils.toString(httpResponse.getEntity());   } else {   response = String.valueOf(statusCode);   }   return response; }


C#Rest服务端

[OperationContract]
[WebInvoke(UriTemplate = "/yyxTest", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
string MensarTest(XCJCQK model);

自己的一点小结,希望对遇到相同问题的人有帮助。
