OkHttp

OkHttp协议介绍

OkHttp是一个第三方类库，用于android中请求网络。
这是一个开源项目,是安卓端最火热的轻量级框架,由移动支付Square公司贡献(该公司还贡献了Picasso和LeakCanary)。用于替代HttpUrlConnection和Apache HttpClient(android API23 里已移除HttpClient)

OkHttp完成get请求

Java代码

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";
    private Handler handler=new Handler();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.get_button:
                get("https://news-at.zhihu.com/api/4/news/latest");
                break;
        }
    }
    private void get(String url) {
        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        builder.readTimeout(30, TimeUnit.SECONDS);//读取超时
        builder.connectTimeout(20,TimeUnit.SECONDS);//连接超时

        OkHttpClient client = builder.build();//获得一个客户对象
        Request request = new Request.Builder().get().url(url).build();//请求对象

        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                final String json = response.body().string();
                Log.i(TAG, "onResponse: "+json);
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(MainActivity.this, json, Toast.LENGTH_SHORT).show();
                    }
                });
            }
        });
    }
}

OkHttp完成post请求

Java代码

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";
    private Handler handler=new Handler();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.post_button:
                post("https://www.apiopen.top/createUser?key=00d91e8e0cca2b76f515926a36db68f5&");
                break;
        }
    }

    private void post(String url) {//map.keyset():所有键的集合   values():所有值得集合
        OkHttpClient client = new OkHttpClient.Builder().build();
        //表单体（放上传的内容）
        FormBody.Builder formBody = new FormBody.Builder();
        FormBody formBody1 = formBody.add("phone","18019173757").add("passwd","666").build();
        
        final Request request = new Request.Builder().post(formBody1).url(url).build();
        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                final String ok = response.body().string();
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(MainActivity.this, ok, Toast.LENGTH_SHORT).show();
                    }
                });
            }
        });
    }
}
