如何使用OkHttp设置连接超时 [英] How to set connection timeout with OkHttp

问题描述

我正在使用OkHttp库开发应用程序，我的麻烦是我找不到如何设置连接超时和套接字超时。

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();

谢谢。

推荐答案

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 中设置的值为在 OkHttp 套接字内的 setSoTimeout 中使用的那个> 连接 类。

Be aware that value set in setReadTimeout is the one used in setSoTimeout on the Socket internally in the OkHttp Connection class.

未在 OkHttpClient上设置任何超时相当于在 setConnectTimeout 或 setReadTimeout 0 的值c $ c>并且根本不会导致超时。可以在找到说明这里。

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.

正如@marceloquinta在评论中提到的 setWriteTimeout 也可以设置。

As mentioned by @marceloquinta in the comments setWriteTimeout can also be set.

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。这可以在这里。

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.

从OkHttp3开始，现在可以通过Builder 如此

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();
