java模拟表单 json数据格式问题，大神请进

String url = "http://120.25.102.84:8000/creditAudit";
PostMethod postMethod = new PostMethod(url);
// 填入各个表单域的值
NameValuePair[] data = {
new NameValuePair("message", JSON.toJSONString(ll))};

  System.out.println("推送成功");
  // 将表单的值放入postMethod中 commons-httpclient.jar  
 postMethod.setRequestBody(data);
  postMethod.getParams().setContentCharset("utf-8");
  postMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET,"utf-8");
  // 执行postMethod
  int statusCode = 0;
  try {
      statusCode = new HttpClient().executeMethod(postMethod);
  } catch (HttpException e) {
      e.printStackTrace();
  } catch (IOException e) {
      e.printStackTrace();
  }
  // HttpClient对于要求接受后继服务的请求，象POST和PUT等不能自动处理转发
  // 301或者302
  if (statusCode == HttpStatus.SC_MOVED_PERMANENTLY
          || statusCode == HttpStatus.SC_MOVED_TEMPORARILY) {
      // 从头中取出转向的地址
      Header locationHeader = postMethod.getResponseHeader("location");
      String location = null;
      if (locationHeader != null) {
          location = locationHeader.getValue();
          System.out.println("diandianLogin:" + location);
      } else {
          System.err.println("Location field value is null.");
      }
      return;
  } else {
      System.out.println(postMethod.getStatusLine());
      String str = "";
      try {
          str = postMethod.getResponseBodyAsString();
      } catch (IOException e) {
          e.printStackTrace();
      }
      System.out.println(str);
  }
  postMethod.releaseConnection();
  return;



          new NameValuePair("message", JSON.toJSONString(ll))};    messages是个list 但是转成json  但是  格式如下

[name=message, value=[{"BAL":"5273.84","BILLDTLS_ID":"AazLIsjsMYnlKYirmNOx","LOANID":"NJGL20160428002","PRERETUAMT":"3052.40"}]]

单我想 修改格式为：

[{"BAL":"5273.84","BILLDTLS_ID":"AazLIsjsMYnlKYirmNOx","LOANID":"NJGL20160428002","PRERETUAMT":"3052.40"}]

请问如何修改，大神勿喷

转换成jsonarray 然后遍历下得到一个

并且我这个是 模拟表单，给别人接口推送数据的

Android6.0已经不支持HttpClient了，建议你换个框架吧

什么东西 ，JsonArray.fromObject(Object obj)这个可以转list，map集合，直接不行么

String str=json.split("value="); str[1]就是你想要的，这种就用字符串分割吧。

//[name=message, value=[{"BAL":"5273.84","BILLDTLS_ID":"AazLIsjsMYnlKYirmNOx","LOANID":"NJGL20160428002","PRERETUAMT":"3052.40"}]]
//把你的JSON转换成以下格式
String json = "{\"name\":\"message\", \"value\":[{\"BAL\":\"5273.84\",\"BILLDTLS_ID\":\"AazLIsjsMYnlKYirmNOx\",\"LOANID\":\"NJGL20160428002\",\"PRERETUAMT\":\"3052.40\"}]}";
JSONObject obj = JSONObject.fromObject(json);

    System.out.println(obj.get("value").toString());
