java.net.SocketTimeoutException：超时

Question

使用OkHttp库，应用程序面临以下SocketTimeoutException问题。 如果请求大小更小，那么它工作正常（小于 1MB）。 我在 10 秒内得到了这个异常，即使我的套接字超时（ readTimeout ）值要高得多。 请求始终失败（大小为 1.8MB）。 当我使用HttpUrlConnection执行请求时，它工作正常。 失败的可能原因是什么？

Answer 1

对于 OkHttp 3，OkHttp 的默认值为 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()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

将此用于 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()

Answer 5

您需要了解仅添加此内容并不能解决您的问题：

OkHttpClient.Builder()
            .connectTimeout(10, TimeUnit.SECONDS)
            .readTimeout(10, TimeUnit.SECONDS)
            .writeTimeout(10, TimeUnit.SECONDS)

如果您使用的是Kotlin + Retrofit + Coroutines，那么只需使用try和catch进行网络操作，例如，

viewModelScope.launch(Dispatchers.IO) {
        try {
            val userListResponseModel = apiEndPointsInterface.usersList()
            returnusersList(userListResponseModel)
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

其中，Exception 是kotlin类型，而不是java.lang

这将处理每个异常，例如，

1. 异常
2. 套接字超时异常
3. 致命例外：DefaultDispatcher 等

这是我的usersList()函数

@GET(AppConstants.APIEndPoints.HOME_CONTENT)
suspend fun usersList(): UserListResponseModel

Answer 6

If you are using Retrofit and Kotlin then use following code:
    var BASE_URL:String="Your URL"
    val clientSetup = OkHttpClient.Builder()
        .connectTimeout(1, TimeUnit.MINUTES)
        .writeTimeout(1, TimeUnit.MINUTES) // write timeout
        .readTimeout(1, TimeUnit.MINUTES) // read timeout
        .build()

    val getClientApi: ApiInterface
        get() {
            var retrofit: Retrofit =  Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(ScalarsConverterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .client(clientSetup)
                .build()
        }

Answer 7

检查您的网址是否正确。 此错误可能是由于错误的 url 行

Answer 8

跑进追赶

runCatching {
       service
}
 .map {
       if (it.isSuccessful && it.body() != null) {
           Success(Unit)
       } else {
           Error(Failure.AuthError.error(it.errorBody()))
       }
}
 .getOrElse {
       Error(Failure.Throwable(it))
}

Answer 9

在我的情况下，将ping 间隔添加到 OkHttp 有助于减少应用程序中的SocketTimeoutExceptions数量。

OkHttpClient.Builder()
        .pingInterval(3, SECONDS)
        .build()

但我不确定这些超时是否与请求大小有关。 我在 github 上的这个 issue 中也提到了它，报告给 OkHttp 库
