堆栈内存溢出
  繁体   English   中英

消息：读取ECONNRESET，堆栈：错误：从Docker容器内的Go客户端调用HapiJs服务器时读取ECONNRESET

[英]message: read ECONNRESET, stack: Error: read ECONNRESET when calling a HapiJs server from a Go client inside a docker container

问题描述

  • 节点版本 ：6.11.1
  • 平台 ：Docker容器中的Ubuntu 14.04。
  • 子系统 ：http

在运行hapijs服务器的Node项目中调用端点时，会遇到一个非常独特的问题。 当直接命中端点时，没有任何问题。

但是，当我们从gohaqd实例中找到它时，我们得到：

170809/044343.745, [log,connection,client,error] message: write EPIPE, stack: Error: write EPIPE at exports._errnoException (util.js:1018:11) at WriteWrap.afterWrite (net.js:800:14)

而且更经常

170809/040643.248, [log,connection,client,error] message: read ECONNRESET, stack: Error: read ECONNRESET at exports._errnoException (util.js:1018:11) at TCP.onread (net.js:568:26)

我知道错误代码的意思是，该应用程序正试图在某个地方写入关闭的连接。 但是对于我的一生，我不知道在哪里。 日志本身来自hapijs，如果我没记错的话， 这行代码 ，但是无论如何都无法弄清楚为什么节点试图写入关闭的连接。

注意，这没有副作用。 该应用程序运行良好：|

我们打开NODE_DEBUG=http, net ，得到以下结果。 读取这些内容时唯一突出的问题是，第二行中， write ret = true行出现两次，如果这意味着任何意义的话。 有人可以帮助我理解它的意思吗？

第一个是直接命中端点时：

    var err error

    endpoint := url

    if endpoint == "" {

        err := json.Unmarshal([]byte(msg), &m)
        if err != nil {

            return false
        }
        endpoint = m["url"]

    for {

        log.Printf("Error hitting endpoint, retrying after 1 second... Error: %s", err.Error())
        time.Sleep(time.Second)
    }
    defer resp.Body.Close()

    // return true only if response is 200 OK
    if resp.StatusCode != 200 {
        bodyBytes, _ := ioutil.ReadAll(resp.Body)
