刚开始学习Android网络请求记录一下
- OKhttp提示错误
android.os.NetworkOnMainThreadException看意思就是不能再主线程中写。 - 提示
not permitted by network security poliy看意思跟iOS里面的策略差不多，iOS使用http请求需要设置一下安全策略，可是我这是百度HTTPS啊，参考文章和解决办法
public class NetWorkACT extends AppCompatActivity { final private static String TAG = "log"; private Button button; Handler handler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); Bundle bundle = msg.getData(); String value = bundle.getString("value"); Log.i(TAG,"请求结果"+value); } }; Runnable runnable = new Runnable() { @Override public void run() { OkHttpClient okHttpClient = new OkHttpClient(); String string = "https://www.baidu.com"; Request request = new Request.Builder().url(string).build(); try { Response response = okHttpClient.newCall(request).execute(); String res = response.body().toString(); System.out.println(res); Message message = new Message(); Bundle bundle = new Bundle(); bundle.putString("value",res); message.setData(bundle); handler.sendMessage(message); } catch (IOException exception){ } } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_net_work_act);// if (android.os.Build.VERSION.SDK_INT > 9) {// StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();// StrictMode.setThreadPolicy(policy);// } button = (Button)findViewById(R.id.start); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { startRequest();// OkHttpClient okHttpClient = new OkHttpClient();// String string = "https://www.baidu.com";// Request request = new Request.Builder().url(string).build();// try {// Response response = okHttpClient.newCall(request).execute();// String res = response.body().toString();// System.out.println("请求接口"+res);// Message message = new Message();// Bundle bundle = new Bundle();// bundle.putString("value",res);// message.setData(bundle);// handler.sendMessage(message);// } catch (IOException exception){//// } } }); } private void startRequest() { new Thread(runnable).start(); }}更多相关文章
