正如Trevor Halvorson指出的那样,您可以callTimeout在客户端 构建期间设置,方法是:
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(20, TimeUnit.SECONDS)
.callTimeout(20, TimeUnit.SECONDS)
.writeTimeout(20, TimeUnit.SECONDS)
.readTimeout(20, TimeUnit.SECONDS)
.retryOnConnectionFailure(false)
.build();
我已经在使用以下版本3.14.0
的虚拟项目中进行了个人测试okhttp3:
implementation 'com.squareup.okhttp3:okhttp:3.14.0'
And setting a timout of 5 seconds and my emulator connection to and connectivity I get
java.net.socketExcpetion: Socket closed: timeout
This is my full :
package com.example.shadowsheep.myapplication;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import java.io.IOException;
import java.io.InterruptedioException;
import java.util.concurrent.TimeUnit;
import androidx.appcompat.app.AppCompatActivity;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TextView helloTextView = findViewById(R.id.helloTextView);
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(5, TimeUnit.SECONDS)
.callTimeout(5, TimeUnit.SECONDS)
.writeTimeout(5, TimeUnit.SECONDS)
.readTimeout(5, TimeUnit.SECONDS)
.retryOnConnectionFailure(false)
.build();
Request request = new Request.Builder()
.url("https://www.versionestabile.it/blog")
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
Log.d("OKHTTP3", e.getMessage());
// You get this failure
runOnUiThread(() -> helloTextView.setText("TIMEOUT - FAILURE -> " + e.getMessage()));
}
@Override
public void onResponse(Call call, Response response) throws IOException {
try {
final String _body = response.body().string();
Log.d("OKHTTP3", _body);
runOnUiThread(() -> {
helloTextView.setText(_body);
});
} catch (InterruptedioException e) {
runOnUiThread(() -> {
// Or this exception depending when timeout is reached
helloTextView.setText("TIMEOUT EXCEPTION->"+ e.getCause() + ": " + e.getMessage());
});
}
}
});
}
}
I’ll give you also my app build.gradle
file.
