java.net.SocketTimeoutException：超時

Question

使用OkHttp庫，應用程序面臨以下SocketTimeoutException問題。 如果請求大小更小，那么它工作正常（小於 1MB）。 我在 10 秒內得到了這個異常，即使我的套接字超時（ readTimeout ）值要高得多。 請求始終失敗（大小為 1.8MB）。 當我使用HttpUrlConnection執行請求時，它工作正常。 失敗的可能原因是什么？

Answer 1

對於 OkHttp 3，OkHttp 的默認值為 10 秒。 您可以將超時增加到 30 秒。

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

Answer 2

我解決了增加writeTimeout()問題。

嘗試：

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

這解決了我的問題：

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

將此用於 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

您需要了解僅添加此內容並不能解決您的問題：

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進行網絡操作，例如，

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

其中，Exception 是kotlin類型，而不是java.lang

這將處理每個異常，例如，

1. 異常
2. 套接字超時異常
3. 致命例外：DefaultDispatcher 等

這是我的usersList()函數

@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

檢查您的網址是否正確。 此錯誤可能是由於錯誤的 url 行

Answer 8

跑進追趕

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

在我的情況下，將ping 間隔添加到 OkHttp 有助於減少應用程序中的SocketTimeoutExceptions數量。

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

但我不確定這些超時是否與請求大小有關。 我在 github 上的這個 issue 中也提到了它，報告給 OkHttp 庫
