AWS X射线跟踪在Node.js中的传出请求上中断 [英] aws x-ray tracing breaks on outgoing requests in Node.js

问题描述

嘿，我正在尝试跟踪Express应用程序的传出请求，但是我无法使它正常工作.

Hey I'm trying to trace outgoing requests from an express app, but I can't get it to work.

当我不使用AWSXRAY.captureHttpsGlobal函数时，一切都能很好地处理传入请求，并且我可以在服务映射"中看到我的应用程序，并且传入请求跟踪也将传入AWS，但是我想尽快跟踪传出请求我添加了AWSXRAY.captureHttpsGlobal，那么什么也没用，也没有任何异常，并且我的守护进程没有打印通常的成功发送一批1段(0.058秒)"

When I dont use the AWSXRAY.captureHttpsGlobal function everything works fine with incoming requests and I can see my application in "Service Map" and my incoming request traces coming in on AWS, but I want to trace outgoing requests and as soon as I add AWSXRAY.captureHttpsGlobal then nothing works and I get no exception or anything, and my Daemon doesnt print the usual "Successfully sent batch of 1 segments (0.058 seconds)"

这是我的代码.

var AWSXRay = require('aws-xray-sdk');
const express = require("express");

var app = express();
app.use(AWSXRay.express.openSegment('MyApp'));

AWSXRay.captureHTTPsGlobal(require('https')); // works when i comment this out
var http = require('https');


app.get('/', function (req, res) {
    http.get("https://google.com", (resp) => {
        res.send("googlefetched")
    });
    //res.send("hello world")

});

app.use(AWSXRay.express.closeSegment());
app.listen(3000, () => console.log('Example app listening on port 3000!'))

推荐答案

可以共享您的代码在哪个节点运行时版本上运行以及您在使用哪个X-Ray SDK版本，以便我们可以尝试重现此问题. ?

could you share which node runtime version your code is running at and which X-Ray SDK version you are using so we can try to reproduce this issue on our side?

同时，我想分享一个自v1.2.0版本以来已解决的先前问题 https://github.com/aws/aws-xray-sdk-node/issues/18 如果不使用响应主体，则整个段将永远不会刷新到守护程序

At the meantime I would like to share a previous issue that has been fixed since v1.2.0 https://github.com/aws/aws-xray-sdk-node/issues/18 where if the response body is not consumed then the entire segment will never be flushed to the daemon.

请让我知道.
