[代码] 运行说明

01	其中http://10.0.2.2为Android访问本机url的ip地址。对应电脑上测试的http://127.0.0.1

02

03	另外执行代码时会抛出异常

04

05	java.net.SocketException: Permission denied

06

07	此为应用访问网络的权限不足 在AndroidManifest.xml中，需要进行如下配置：

08	<uses-permission Android:name="android.permission.INTERNET" />

09

就加在

10	</manifest>

11

之前就好了

12

然后测试通过。
