python搭建简单本地服务器

没搭建过服务器的人想搭建一个确实有点头疼，ME…

不过搭建出来后，如标题，没搭过的骚年继续，assert(reader instanceof 没服务器经验);

环境

Ubuntu15.04

Server

• 创建webserver3g.py

• 运行

$ python webserver3g.py

Client

private void httpGet() {
    String url = "http://192.168.0.101:8888/hello";
    OkHttpUtils.get().url(url).build()
            .execute(new StringCallback() {
                @Override
                public void onError(Call call, Exception e) {
                }

                @Override
                public void onResponse(String response) {
                    Log.d(TAG, response);
                }
            });
}

**注意：**1.添加INTERNET权限;2.添加compile 'com.zhy:okhttputils:2.2.0'作为网络请求;3.将192.168.0.101换成自己Server的IP;4.手机与Server在同一路由
