android客户端从服务器端获取json数据并解析的实现代码

android客户端从服务器端获取客户端从服务器端获取json数据并解析的实现代码数据并解析的实现代码

今天总结一下android客户端从服务器端获取json数据的实现代码，需要的朋友可以参考下

首先客户端从服务器端获取json数据

1、利用HttpUrlConnection

复制代码 代码如下:

/**

* 从指定的URL中获取数组

* @param urlPath

int len = 0;

URL url = new URL(urlPath);

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

InputStream inStream = conn.getInputStream();

while ((len = inStream.read(data)) != -1) {

outStream.write(data, 0, len);

}

inStream.close();

return new String(outStream.toByteArray());//通过out.Stream.toByteArray获取到写的数据

}

* @param url

* @return

* @throws Exception

*/

public static String doPost(List<NameValuePair> params, String url)

throws Exception {

String result = null;

// 获取HttpClient对象

HttpClient httpClient = new DefaultHttpClient();

// 新建HttpPost对象

}

/*// 连接超时

httpClient.getParams().setParameter(

CoreConnectionPNames.CONNECTION_TIMEOUT, 3000);

// 请求超时

httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,

3000);*/

// 获取HttpResponse实例

HttpResponse httpResp = httpClient.execute(httpPost);

// 判断是够请求成功

return result;

}

其次Json数据解析：

json数据：

[{"id":"67","biaoTi":"G","logo":"http://www.nuoter.com/wtserver/resources/upload/13508741845270.png","logoLunbo":"http://www.nuoter.com/wtserver/resources/upload/13509015004480.jpg","yuanJia":"0","xianJia":"0"},

{"id":"64","biaoTi":"444","logo":"http://www.nuoter.com/wtserver/resources/upload/13508741704400.png","logoLunbo":"http://172.16.1.75:8080/wtserver/resources/upload/13508741738500.png","yuanJia":"0","xianJia":"0"},

{"id":"62","biaoTi":"jhadasd","logo":"http://www.nuoter.com/wtserver/resources/upload/13508741500450.png","logoLunbo":"http://172.16.1.75:8080/wtserver/resources/upload/13508741557450.png","yuanJia":"1","xianJia":"0"}]

复制代码 代码如下:

/**

* 解析

JSONArray jsonArray = null;

// 初始化list数组对象

ArrayList<HashMap<String, Object>> list = new ArrayList<HashMap<String, Object>>();

jsonArray = new JSONArray(jsonStr);

for (int i = 0; i < jsonArray.length(); i++) {

JSONObject jsonObject = jsonArray.getJSONObject(i);

// 初始化map数组对象

HashMap<String, Object> map = new HashMap<String, Object>();

map.put("logo", jsonObject.getString("logo"));

map.put("logoLunbo", jsonObject.getString("logoLunbo"));

return list;

}
