超过 30 秒的 connectTimeout 对 OKHTTP 不起作用 [英] connectTimeout more than 30 seconds does not work for OKHTTP

问题描述

我正在尝试将 connectTimeout 设置为 2 分钟，但仅在 30 秒后尝试仍然失败.

I am trying to set connectTimeout to 2 minutes, but still the tries fails after 30 seconds only.

我的客户是这样的:

client = new OkHttpClient.Builder()
            .callTimeout(2, TimeUnit.MINUTES)
            .connectTimeout(2, TimeUnit.MINUTES)
            .writeTimeout(2, TimeUnit.MINUTES)
            .readTimeout(2, TimeUnit.MINUTES)
            .build();

public Call callReq(Callback callback) {


    Request.Builder builder = new Request.Builder()
            .url("http://203.0.113.1");

    //Create request builder
    final Request request = builder
            .build();

    Call call = client.newCall(request);

    call.enqueue(callback);
    return call;
}

我在 30 秒内收到的此呼叫的失败响应.我想让它等 2 分钟.如果我将超时减少到 15 秒，它会起作用.

The failure response of this call I am receiving in 30 seconds. I wanted that to wait for 2 minutes. It works if I reduce the timeout to 15 seconds.

推荐答案

我怀疑您遇到了一些额外的平台超时，例如我的测试在 1:15 后超时.

I suspect you are hitting some additional platform timeouts, e.g. my test timed out after 1:15.

package okhttp3.curl

import okhttp3.OkHttpClient
import okhttp3.Request
import okhttp3.Response
import okhttp3.logging.LoggingEventListener
import java.util.concurrent.TimeUnit

fun main() {
  val listener = LoggingEventListener.Factory()
  val client = OkHttpClient.Builder()
      .eventListenerFactory(listener)
      .callTimeout(2, TimeUnit.MINUTES)
      .connectTimeout(2, TimeUnit.MINUTES)
      .writeTimeout(2, TimeUnit.MINUTES)
      .readTimeout(2, TimeUnit.MINUTES)
      .build()
  val response: Response = client.newCall(
        Request.Builder().url("http://203.0.113.1").build()).execute()

  println(response.request.url)
}

输出
