Okhttp系列：简单的不用传参的Get请求示例

上一篇：Okhttp官方文档

网络权限

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

引入okhttp包：

implementation 'com.squareup.okhttp3:okhttp:3.14.4'

在app module下的build.gradle文件中配置java8，否则会报错。

android { compileSdkVersion 30 buildToolsVersion "30.0.3" defaultConfig { ... } buildTypes { ... } // 增加java8的配置 compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } }

MainActivity代码

public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); new Thread(new Runnable() { @Override public void run() { String url = "https://publicobject.com/helloworld.txt"; //初始化okhttp客户端 OkHttpClient client = new OkHttpClient(); //创建请求体 Request request = new Request.Builder().url(url).get().build(); //执行请求 Response response = null; try { response = client.newCall(request).execute(); //获取服务器响应数据 if (response.isSuccessful()) { String result = response.body().string(); Log.e("xxx", result); } } catch (IOException e) { e.printStackTrace(); } } }).start(); } }
