Java 如何使用OkHttp设置连接超时

我正在使用OkHttp库开发应用程序，我的问题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();

---

从OkHttp3开始您可以通过类似的方法来实现这一点

您还可以查看配方

对于旧版本，您只需执行此操作

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，

setReadTimeout

中设置的值是在

OkHttp

类的

Socket

内部使用的值

在

OkHttpClient

上不设置任何超时相当于在

setConnectTimeout

或

setReadTimeout

上设置值

0

，将导致根本没有超时。可以找到描述

正如@marceloquinta在注释

setWriteTimeout

中提到的，也可以进行设置

---

从版本

2.5.0开始，

read/write/connect超时值默认设置为10秒，如@ChristerNordvik所述。可以看出这一点。

对于

改装2.0.0-beta1

或

beta2

，代码如下所示：

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();

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();

OkHttpClient okHttpClient = new OkHttpClient()
    .newBuilder()
    .connectTimeout(10,TimeUnit.SECONDS)
    .writeTimeout(10,TimeUnit.SECONDS)
    .readTimeout(30,TimeUnit.SECONDS)
    .build();

---

对于okhttp3来说，这有点变化

现在，您可以使用生成器而不是setter设置时间，如下所示：

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(10, TimeUnit.SECONDS)
        .writeTimeout(10, TimeUnit.SECONDS)
        .readTimeout(30, TimeUnit.SECONDS)
        .build();

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(Duration.ofSeconds(5)) // timeout: 5 seconds
    .build();

更多信息可在其wiki中找到：

对于改装

改装：2.0.0-beta4

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();

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();

OkHttpClient okHttpClient = new OkHttpClient()
    .newBuilder()
    .connectTimeout(10,TimeUnit.SECONDS)
    .writeTimeout(10,TimeUnit.SECONDS)
    .readTimeout(30,TimeUnit.SECONDS)
    .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();

---

添加渐变文件和同步项目：

compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.google.code.gson:gson:2.6.2'

在Java类中添加：

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();

---

现在变了。将

.Builder（）

替换为

.newBuilder（）

从http:3.9.0开始，代码如下所示：

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();

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();

OkHttpClient okHttpClient = new OkHttpClient()
    .newBuilder()
    .connectTimeout(10,TimeUnit.SECONDS)
    .writeTimeout(10,TimeUnit.SECONDS)
    .readTimeout(30,TimeUnit.SECONDS)
    .build();

这对我很有用：

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(10, TimeUnit.SECONDS)
    .readTimeout(10, TimeUnit.SECONDS)
    .writeTimeout(10, TimeUnit.SECONDS)
    .retryOnConnectionFailure(false) <-- not necessary but useful!
    .build();

OkHttpClient=new OkHttpClient.Builder（）
.connectTimeout（10，时间单位为秒）
.readTimeout（10，时间单位为秒）
.writeTimeout（10，时间单位。秒）
.retryOnConnectionFailure（false）如果要自定义配置，请先使用以下方法创建OKhttpclient，然后在其上添加生成器

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：
3.11.0
或更高版本

来自http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.
 *
 * <p>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;
}

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
我已经从版本
3.12.0
向OkHttp添加了新的API，您可以这样设置超时：

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(10, TimeUnit.SECONDS)
        .writeTimeout(10, TimeUnit.SECONDS)
        .readTimeout(30, TimeUnit.SECONDS)
        .build();

OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(Duration.ofSeconds(5)) // timeout: 5 seconds
    .build();

注意：这需要API
26+
，因此如果您支持旧版本的Android，请继续使用
（5，TimeUnit.SECONDS）
您可以设置调用超时，以覆盖解析DNS、连接、写入请求正文、服务器处理和读取响应正文的整个周期

val client = OkHttpClient().newBuilder().callTimeout(CALL_TIMEOUT_IN_MINUTES, TimeUnit.MINUTES).build()

有没有办法为每个请求设置不同的超时（每个请求都有相同的静态客户端）？您可以为每个请求设置特定的超时：这里有一些信息：不要忘记写入超时：client.setWriteTimeout（10，TimeUnit.SECONDS）@MiguelLavigne仅供参考，OkHttp在2.5.0中更改为默认超时10秒。过时的答案您选择的答案不再有效。也许您应该编辑问题以指定okhttp的版本。
