Android向Rest服务Post数据遇到的Date类型数据问题

时间:2022-06-18 15:45:08

  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。
