java - 如何使用OkHttp设置连接超时
我正在使用OkHttp库开发app，我的麻烦是我找不到如何设置连接超时和套接字超时。
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder().url(url).build();
Response response = client.newCall(request).execute();
谢谢。

你只需要这样做
OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(15, TimeUnit.SECONDS); // connect timeout
client.setReadTimeout(15, TimeUnit.SECONDS); // socket timeout
Request request = new Request.Builder().url(url).build();
Response response = client.newCall(request).execute();
请注意，setWriteTimeout中设置的值是237332210281768652 setWriteTimeout setWriteTimeout内部的0中使用的值。
未在setWriteTimeout上设置任何超时相当于在setConnectTimeout或setReadTimeout上设置值0，并且将导致根本没有超时。 说明可以在这里找到。
正如@marceloquinta在评论setWriteTimeout中提到的那样也可以设置。
从版本2.5.0开始，默认情况下，如@ChristerNordvik所述，读/写/连接超时值设置为10秒。 这可以在这里看到。
从OkHttp3开始，现在可以通过Builder这样做
client = new OkHttpClient.Builder()
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build();

对于okhttp3，这已经改变了一点。
现在您使用构建器设置时间，而不是设置器，如下所示：
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build();

对于Retrofit改造：2.0.0-beta4，代码如下
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(logging)
.connectTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://api.yourapp.com/")
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();

对于Retrofit 2.0.0-beta1或beta2，代码如下
OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
client.setWriteTimeout(30, TimeUnit.SECONDS);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://api.yourapp.com/")
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();

//add in gradle and sync
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.google.code.gson:gson:2.6.2'
import okhttp3.OkHttpClient;
import okhttp3.OkHttpClient.Builder;
Builder b = new Builder();
b.readTimeout(200, TimeUnit.MILLISECONDS);
b.writeTimeout(600, TimeUnit.MILLISECONDS);
// set other properties
OkHttpClient client = b.build();

像这样：
//New Request
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BASIC);
final OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(logging)
.connectTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)
.build();

它现在改变了。 将.Builder()替换为.newBuilder()
从okhttp：3.9.0开始，代码如下：
OkHttpClient okHttpClient = new OkHttpClient()
.newBuilder()
.connectTimeout(10,TimeUnit.SECONDS)
.writeTimeout(10,TimeUnit.SECONDS)
.readTimeout(30,TimeUnit.SECONDS)
.build();

这对我有用...来自[https://github.com/square/okhttp/issues/3553]
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(10, TimeUnit.SECONDS)
.readTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.retryOnConnectionFailure(false)
.build();

如果要自定义配置，请先使用以下方法创建OKhttpclient，然后在其上添加构建器。
private final OkHttpClient client = new OkHttpClient();
// Copy to customize OkHttp for this request.
OkHttpClient client1 = client.newBuilder()
.readTimeout(500, TimeUnit.MILLISECONDS)
.build();
try (Response response = client1.newCall(request).execute()) {
System.out.println("Response 1 succeeded: " + response);
} catch (IOException e) {
System.out.println("Response 1 failed: " + e);
}

okhttp版本：3.12.0或更高版本
来自okhttp的源代码
/**
* Sets the default connect timeout for new connections. A value of 0 means no timeout,
* otherwise values must be between 1 and {@link Integer#MAX_VALUE} when converted to
* milliseconds.
*
*
The connectTimeout is applied when connecting a TCP socket to the target host.
* The default value is 10 seconds.
*/
public Builder connectTimeout(long timeout, TimeUnit unit) {
connectTimeout = checkDuration("timeout", timeout, unit);
return this;
}
3.12.0可以是以下任何值
TimeUnit.NANOSECONDS
TimeUnit.MICROSECONDS
TimeUnit.MILLISECONDS
TimeUnit.SECONDS
TimeUnit.MINUTES
TimeUnit.HOURS
TimeUnit.DAYS
示例代码
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(5000, TimeUnit.MILLISECONDS)/*timeout: 5 seconds*/
.build();
String url = "https://www.google.com";
Request request = new Request.Builder()
.url(url)
.build();
try {
Response response = client.newCall(request).execute();
} catch (IOException e) {
e.printStackTrace();
}
更新
我从版本3.12.0向okhttp添加了新的api，你可以像这样设置超时
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(Duration.ofSeconds(5))/*timeout: 5 seconds*/
.build();
