java.net.SocketTimeoutException：timeout

Question

使用OkHttp库，应用程序正面临以下SocketTimeoutException问题。如果请求大小较小，那么它工作正常（小于1MB）。我在10秒内收到此异常，即使我的套接字超时（readTimeout）值更高。它总是失败的请求（大小是1.8MB）。当我用HttpUrlConnection执行请求时它工作正常。什么可能是失败的原因？

Answer 1

对于OkHttp 3，OkHttp的默认值是10秒。您可以将超时增加到30秒。

OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS); // connect timeout
client.setReadTimeout(30, TimeUnit.SECONDS);    // socket timeout

Answer 2

我解决了增加writeTimeout()的问题。

尝试：

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.connectTimeout(5, TimeUnit.MINUTES) // connect timeout
.writeTimeout(5, TimeUnit.MINUTES) // write timeout
.readTimeout(5, TimeUnit.MINUTES); // read timeout

okHttpClient = builder.build();

Answer 3

这解决了我的问题：

OkHttpClient innerClient = new OkHttpClient.Builder()
            .connectTimeout(5, TimeUnit.MINUTES) // connect timeout
            .writeTimeout(5, TimeUnit.MINUTES) // write timeout
            .readTimeout(5, TimeUnit.MINUTES) // read timeout
            .build();

Answer 4

用于Kotlin

 val client1 = OkHttpClient.Builder()
                .connectTimeout(2, TimeUnit.MINUTES)
                .writeTimeout(2, TimeUnit.MINUTES) // write timeout
                .readTimeout(2, TimeUnit.MINUTES) // read timeout
                .addInterceptor(
                    BasicAuthInterceptor(
                        AmvaccAppConstants.AUTHENTICATE_USER_NAME, AmvaccAppConstants.AUTHENTICATE_USER_PASSWORD
                    )
                )
                .addInterceptor(interceptor)
                .build()
