如何将 HttpEntity 转换为 JSON? [英] How to convert HttpEntity into JSON?

问题描述

我想从网络服务中检索 JSON 并解析它.
我走对路了吗?

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) {
    }

很遗憾我不知道如何将 HttpEntity 转换为 JSONObject.

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

这是我的 JSON(摘录):

This is my JSON (extract):

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

推荐答案

您可以将字符串转换为 json 为:

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) {
  }
