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) { }

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）{ }
