无法运行Angular>2 e2e在代理后面使用量角器

问题描述

将感谢您的帮助！

• 我正在Windows上运行
• 我在全球范围内安装了量角器版本5.3.0
• 在更新Webdriver之前，我运行过: webdriver-manager clean
• 和更新的版本如下:

• 节点版本9.2.1
• npm版本5.7.1
• 在启动e2e之前先启动开发服务器.

我的protractor.conf文件如下:

my protractor.conf file is as follows:

     const { SpecReporter } = require('jasmine-spec-reporter');

    exports.config = {
      allScriptsTimeout: 11000,
      specs: [
        './e2e/**/*.e2e-spec.ts'
      ],
        capabilities: {
    'browserName': 'chrome',
    'proxyType': 'manual',
    'httpProxy': 'http://my-proxy:8080'
  },
      directConnect: true,
      baseUrl: 'http://localhost:4200/',
      framework: 'jasmine',
      jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,
        print: function() {}
      },
      beforeLaunch: function() {
        require('ts-node').register({
          project: 'e2e/tsconfig.e2e.json'
        });
      },
      onPrepare() {
        jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
      }
    };

尝试通过以下方式首先运行测试: ng e2e 第二个:

Tried to ran tests first by: ng e2esecond by:

ng e2e --config ./protractor.conf.js --specs ./e2e\app.e2e-spec.ts

仍然出现此代理错误:

events.js:136
      throw er; // Unhandled 'error' event
      ^

    Error: getaddrinfo ENOTFOUND chromedriver.storage.googleapis.com chromedriver.storage.googleapis.com:443
        at errnoException (dns.js:55:10)
        at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:97:26)

推荐答案

ng e2e 将在后台执行 webdriver-manager启动/更新，而 webdriver-管理员启动将访问"chromedriver.storage.googleapis.com"以查询最新的webdriver二进制文件，您的错误来自此处.

ng e2e will execute webdriver-manager start/update in background, and webdriver-manager start will access "chromedriver.storage.googleapis.com" to query latest webdriver binary, your error comes from here.

因为 ng e2e 无法接受来自cli或预配置文件的代理，这是为 webdriver-manager启动/更新设置代理的唯一方法，code> ng e2e 是通过环境变量来实现的.

Because ng e2e can't accept proxy from cli or pre-configured file, the only way you can set proxy for webdriver-manager start/update triggered by ng e2e is by Environment Variable.

添加以下3个环境变量:


Add below 3 Environment Variables:


HTTP_PROXY = http://my-proxy:port
HTTPS_PROXY = http://my-proxy:port
NO_PROXY = localhost,127.0.0.1, .yourcompany.com

在新的cmd窗口中尝试 ng e2e (不要在旧的cmd窗口中尝试)

Try ng e2e in new cmd window (don't try in old cmd window)

仅供参考，一旦添加了3个环境变量，就无需在执行 webdriver-manager start/update 时在cli中传递-proxy .

FYI, once you add the 3 Environment Variables, you no need to pass --proxy in cli when execute webdriver-manager start/update.
