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();
答案 0 :(得分:284)
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setSoTimeout
Connection
类内部Socket
OkHttp
中使用的值。
未在OkHttpClient
设置任何超时相当于在0
或setConnectTimeout
上设置setReadTimeout
的值,并且根本不会导致超时。可以找到说明here。
正如@marceloquinta在评论中提到的setWriteTimeout
也可以设置。
自版本2.5.0起,读/写/连接超时值默认设置为10秒,如@ChristerNordvik所述。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();
您还可以查看食谱here。

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改装: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();

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();

//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();

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();
}
我已经从3.12.0
版本向okhttp添加了新的api,您可以这样设置超时时间:
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);
}

您可以设置一个呼叫超时,以覆盖从解析DNS,连接,编写请求正文,服务器处理以及读取响应正文的整个周期。
val client = OkHttpClient().newBuilder().callTimeout(CALL_TIMEOUT_IN_MINUTES, TimeUnit.MINUTES).build()
