Android开发之HttpClient网络请求以Json方式提交Post请求代码

public class PayHttpUtils {
    /**
     * @param url 请求的网址
     */
    public static String GetSingleCabCollect(String url) {
        HttpPost httpPost = new HttpPost(url);
        JSONObject jsonParam = new JSONObject();
        try {
            jsonParam.put("loginName", "admin");
            jsonParam.put("loginPwd", "admin");
        } catch (JSONException e) {
            e.printStackTrace();
        }
        StringEntity entity = null;//解决中文乱码问题
        try {
            entity = new StringEntity(jsonParam.toString(), "utf-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        if (entity != null) {
            entity.setContentEncoding("UTF-8");
            entity.setContentType("application/json");
        }
        httpPost.setEntity(entity);
        HttpClient httpClient = new DefaultHttpClient();
        // 获取HttpResponse实例
        HttpResponse httpResp = null;
        try {
            httpResp = httpClient.execute(httpPost);
        } catch (IOException e) {
            e.printStackTrace();
        }
        // 判断是够请求成功
        if (httpResp != null) {
            if (httpResp.getStatusLine().getStatusCode() == 200) {
                // 获取返回的数据
                String result = null;
                try {
                    result = EntityUtils.toString(httpResp.getEntity(), "UTF-8");
                    Log.e("HttpPost方式请求成功，返回数据如下：", result);
                    return result;
                } catch (IOException e) {
                    e.printStackTrace();
                }
            } else {
                Log.e("打印数据", "HttpPost方式请求失败" + httpResp.getStatusLine().getStatusCode());
            }
        }
        return null;
    }
}

如何调用呢？

 final String result = PayHttpUtils.GetSingleCabCollect("http://10.168.65.144:8012/wallet/admin/login");

我们来看下返回值：
