Angular 7 e2e连接ETIMEDOUT，无法建立隧道套接字

Question

我想使用量角器在Angular项目中使用e2e测试。 运行ng e2e会导致错误

Error: connect ETIMEDOUT 216.58.201.112:443
at Object._errnoException (util.js:992:11)
at _exceptionWithHostPort (util.js:1014:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1186:14)

我遵循此设置。 首先，我设置Windows环境的HTTP_PROXY变量。

然后，我创建了src/proxy.conf.js ，使其看起来像这样。

var HttpsProxyAgent = require('https-proxy-agent');

// https://angular.io/guide/build#proxying-to-a-backend-server
var proxyConfig = [{
  context: '/api',
  // target: 'http://your-remote-server.com:3000',
  target: 'http://172.24.61.70',
  secure: false
}];

function setupForCorporateProxy(proxyConfig) {
  var proxyServer = process.env.http_proxy || process.env.HTTP_PROXY;
  if (proxyServer) {
    var agent = new HttpsProxyAgent(proxyServer);
    console.log('Using corporate proxy server: ' + proxyServer);
    proxyConfig.forEach(function(entry) {
      entry.agent = agent;
    });
  }
  return proxyConfig;
}

module.exports = setupForCorporateProxy(proxyConfig);

最后，我在angular.json serve添加到architect 。

"architect": {
    "e2e": {
      ...
    },
    "serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "options": {
        "browserTarget": "my-portal:build",
        "proxyConfig": "src/proxy.conf.js"
      }
    },
    "lint": {
      ...
    }
  }

现在我得到一个错误：

Error: tunneling socket could not be established, cause=getaddrinfo ENOTFOUND 8080 8080:80
at ClientRequest.onError (C:\projects\star-card-frontend\node_modules\tunnel-agent\index.js:177:17)

编辑

出于某种原因， tunnel-agent接收到错误的代理选项：

{  
   host:'8080',
   port:0,
   proxyAuth:null,
   headers:{  
      host:'chromedriver.storage.googleapis.com:443'
   }
}

Answer 1

尝试在量角器配置中设置代理。 像这样设置stg：

config = {
    capabilities: {
        proxy: {
            proxyType: 'system'
            httpProxy: process.env.http_proxy || process.env.HTTP_PROXY
        }
    }
}

Answer 2

好的，挖掘node_modules发现， url.js使用的tunnel.js中的解析器解析了我的HTTP_PROXY环境变量，但它期望使用协议完全ulr。 因此，将协议添加到HTTP_PROXY => http://172.24.72.10:8080解决此问题。
