如何转换HttpEntity成JSON？ [英] How to convert HttpEntity into JSON?

问题描述

我想从web服务检索JSON和解析它，然后。
我是在正确的道路？

  HttpClient的HttpClient的=新DefaultHttpClient（）;
    HTTPGET HTTPGET =新HTTPGET（URL）;
    HTT presponse响应;
    尝试 {
        响应= httpclient.execute（HTTPGET）;
        HttpEntity实体= response.getEntity（）;

        如果（实体！= NULL）{
           //解析JSON
        }

    }赶上（例外五）{
    }
 

不幸的是，我不知道如何转换 HttpEntity 成JSONObject的。

这是我的JSON（摘录）：

  {
    名：
        {
            名：扎卡里
        }，
        {
            名：悦
        }，
        {
            名：威廉
        }
    ]
}
 

解决方案

您可以将字符串转换为JSON作为：

 尝试{
        响应= httpclient.execute（HTTPGET）;
        HttpEntity实体= response.getEntity（）;

        如果（实体！= NULL）{
           字符串retSrc = EntityUtils.toString（实体）;
           //解析JSON
           JSONObject的结果=新的JSONObject（retSrc）; //字符串转换为JSON对象

             JSONArray tokenList = result.getJSONArray（名称）;
             的JSONObject OJ = tokenList.getJSONObject（0）;
             字符串标记= oj.getString（姓名）;
        }
}
 赶上（例外五）{
  }
 

I want to retrieve JSON from a web-service and parse it then.
Am I on the right way?

    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet(url);
    HttpResponse response;
    try {
        response = httpclient.execute(httpget);
        HttpEntity entity = response.getEntity();

        if (entity != null) {
           // parsing JSON
        }

    } catch (Exception e) {
    }

Unfortunately I don't know how to convert HttpEntity into a JSONObject.

This is my JSON (extract):

{
    "names": [
        {
            "name": "Zachary"
        },
        {
            "name": "Wyatt"
        },
        {
            "name": "William"
        }
    ]
}

解决方案

You can convert string to json as:

try {
        response = httpclient.execute(httpget);
        HttpEntity entity = response.getEntity();

        if (entity != null) {
           String retSrc = EntityUtils.toString(entity); 
           // parsing JSON
           JSONObject result = new JSONObject(retSrc); //Convert String to JSON Object

             JSONArray tokenList = result.getJSONArray("names");
             JSONObject oj = tokenList.getJSONObject(0);
             String token = oj.getString("name"); 
        }
}
 catch (Exception e) {
  }
