问题
I am developing app using OkHttp library and my trouble is I cannot find how to set connection timeout and socket timeout.
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder().url(url).build();
Response response = client.newCall(request).execute();
回答1:
You simply have to do this
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();
Be aware that value set in setReadTimeout is the one used in setSoTimeout on the Socket internally in the OkHttp Connection class.
Not setting any timeout on the OkHttpClient is the equivalent of setting a value of 0 on setConnectTimeout or setReadTimeout and will result in no timeout at all. Description can be found here.
As mentioned by @marceloquinta in the comments setWriteTimeout can also be set.
As of version 2.5.0 read / write / connect timeout values are set to 10 seconds by default as mentioned by @ChristerNordvik. This can be seen here.
As of OkHttp3 can now do this through the Builder like so
client = new OkHttpClient.Builder()
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build();
You can also view the recipe here.
回答2:
For okhttp3 this has changed a bit.
Now you set up the times using the builder, and not setters, like this:
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build();
More info can be found in their wiki: https://github.com/square/okhttp/blob/b3dcb9b1871325248fba917458658628c44ce8a3/docs/recipes.md#timeouts-kt-java

For Retrofit retrofit:2.0.0-beta4 the code goes as follows
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();

For Retrofit 2.0.0-beta1 or beta2, the code goes as follows
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();
回答6:
It's changed now. Replace .Builder() with .newBuilder()
As of okhttp:3.9.0 the code goes as follows:
OkHttpClient okHttpClient = new OkHttpClient()
.newBuilder()
.connectTimeout(10,TimeUnit.SECONDS)
.writeTimeout(10,TimeUnit.SECONDS)
.readTimeout(30,TimeUnit.SECONDS)
.build();
回答7:
like so:
//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();
回答8:
this worked for me ... from 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();
回答9:
okhttp version:3.11.0 or higher
from okhttp source code
/**
* 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 can be any value of below
TimeUnit.NANOSECONDS
TimeUnit.MICROSECONDS
TimeUnit.MILLISECONDS
TimeUnit.SECONDS
TimeUnit.MINUTES
TimeUnit.HOURS
TimeUnit.DAYS
example code
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();
}
Updated
I have add new api to okhttp from version 3.12.0, you can set timeout like this:
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(Duration.ofSeconds(5))/*timeout: 5 seconds*/
.build();
NOTE: This requires API 26+ so if you support older versions of Android, continue to use (5, TimeUnit.SECONDS).
回答10:
If you want to customize the configuration then use the below methodology of creating OKhttpclient first and then add builder on top of it.
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);
}
回答11:
You can set a call timeout to cover the entire cycle from resolving DNS, connecting, writing the request body, server processing, and reading the response body.
val client = OkHttpClient().newBuilder().callTimeout(CALL_TIMEOUT_IN_MINUTES, TimeUnit.MINUTES).build()
