  它现在改变了 . 用 .newBuilder() 替换 .Builder()

  截至 okhttp:3.9.0 ，代码如下：

  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();

  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();

  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， setReadTimeout 中设置的值是 OkHttp Connection类内部 Socket 上的 setSoTimeout 中使用的值 .

  不在 OkHttpClient 上设置任何超时相当于在 setConnectTimeout 或 setReadTimeout 上设置 0 的值，并且根本不会导致超时 . 描述可以找到here .

  正如@marceloquinta在评论中提到的 setWriteTimeout 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 . 这可以看作here .

  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();

  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) <-- not necessary but useful!
          .build();

  okhttp版本： 3.11.0 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.
   *
   * <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;
  }
  

  unit 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();
  

  NOTE: 这需要API 26，因此如果您支持旧版Android，请继续使用 (5, TimeUnit.SECONDS) .

  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);
      }
