github-actions - Github 节点操作 http 错误总是导致作业失败

问题描述

我有一个看起来像这样的 github 操作：

const http = require('http');
const core = require('@actions/core');


const options = {
    hostname: 'mydomain.com',
    port: 80,
    path: '/webhook',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
    }
};

const postData = {
    foo: 'bar'
}

try {
    
    const strPostData = querystring.stringify(postData);
    options.headers['Content-Length'] = Buffer.byteLength(strPostData);

    const req = http.request(options)
    req.write(strPostData)
    req.end()

} catch (error) {
    core.info(error.message);
}

如果mydomain.com/webhook处于脱机状态，我的工作将在此操作上失败，记录：

events.js:187
      throw er; // Unhandled 'error' event
      ^

Error: connect ECONNREFUSED xxx.xxx.xxx.xxx:80
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1129:14)
Emitted 'error' event on ClientRequest instance at:
    at Socket.socketErrorListener (_http_client.js:406:9)
    at Socket.emit (events.js:210:5)
    at emitErrorNT (internal/streams/destroy.js:92:8)
    at emitErrorAndCloseNT (internal/streams/destroy.js:60:3)
    at processTicksAndRejections (internal/process/task_queues.js:80:21) ***
  errno: 'ECONNREFUSED',
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: 'xxx.xxx.xxx.xxx',
  port: 80
***

为什么它失败了，为什么没有try catch抓住这个？

如果此操作失败，我不希望整个作业失败，那么如何捕获此失败并将其隐藏在 GitHub 运行器中？

解决方案

您将需要收听该'error'事件才能捕捉到这个

const strPostData = querystring.stringify(postData);
options.headers['Content-Length'] = Buffer.byteLength(strPostData);

const req = http.request(options)

req.on('error', (err) => {/*Error Caught*/})

req.write(strPostData)
req.end()
