typescript - 使用 GOT 发起 API 请求时量角器脚本失败

Question

我正在尝试从request迁移到got。

使用节点执行独立 javascript 文件时，我可以使用got成功执行 API 调用

但是我在执行来自量角器规范文件的相同请求时面临挑战。

./tsconfig.js

{

    "outDir": "build",

    "esModuleInterop": true 
  }
}

./src/GotImpl.ts - 这个类有一个方法executeGetRequest来根据提供的 requestURL 执行一个 get 操作

const got = require('got');

export class GotImpl {
    options: any;
    responseBody: any;

    constructor() {
        this.options = {};
        this.options['headers'] = {};
        this.options['method'] = "GET";
        this.options.https = {};
        this.options.https.rejectUnauthorized = false;
    }

    async executeGetRequest(requestURL: string): Promise<any> {
        return new Promise<any>(async (resolve, reject) => {
            let successfulExecution: boolean = false;
            let apiRes = await got(requestURL, this.options);
            resolve(await apiRes.body);
        })

    }
}

./src/basic-node-test.ts - 这个文件是一个简单的 TypeScript 文件，通过调用GotImpl类的executeGetRequest方法来执行 get 操作

import { GotImpl } from "./GotImpl"

(async () => {

    const gotTest = new GotImpl();
    await gotTest.executeGetRequest('https://jsonplaceholder.typicode.com/todos/1').then(async (responseBody) => {
        console.log('Response Body: ' + (await JSON.stringify(JSON.parse(responseBody), null, 5)));
    });
})();

执行 basic-node-test.ts 文件时的输出【执行成功】

$ node ./build/basic-node-test.js 
Response Body: {
     "userId": 1,
     "id": 1,
     "title": "delectus aut autem",
     "completed": false
}

问题

现在，我正在尝试在 Protractor 脚本中执行executeGetRequest方法（GotImpl类）

./src/protractor-test.ts - 量角器规范文件

import { GotImpl } from "./GotImpl";

describe('Got in Protractor', () => {
    it('Get Access Managers based on TIN', async (done) => {
        console.log("Start of GOT Test");
        const gotTest = new GotImpl();
        await gotTest.executeGetRequest('https://jsonplaceholder.typicode.com/todos/1').then(async (responseBody) => {
            console.log('Response Body: ' + (await JSON.stringify(JSON.parse(responseBody), null, 5)));
        });
        console.log("End of GOT Test")
        await done();
    });

    process.on('unhandledRejection', (reason) => {
        console.error(reason);
        process.exit(1);
    });

});

./globals.js - 捕获全局变量

var path = require("path");
var fs = require("fs");

module.exports = function setGlobals() {
  global.__root = path.dirname(fs.realpathSync(__filename));
  global.__specs = path.join(__root, "/build/");
};

./config/protractor.config.js

require('../globals').call();

var chromeHeadless = {
    browserName: 'chrome',

    chromeOptions: {
        args: [
            "--no-sandbox",
            "--headless",
            "--disable-gpu",
            "--window-size=800,600",
            '--disable-extensions',
            '--disable-plugins',
            '--disable-infobars'
        ],
        prefs: {
            'profile.password_manager_enabled': false,
            'credentials_enable_service': false,
            'password_manager_enabled': false
        }
    }
}

exports.config = {
    framework: 'jasmine',
    capabilities: chromeHeadless,
    directConnect: true,
    specs: [__specs + 'protractor-test.js']
}

使用 got 执行 API 请求时在 Protractor 中引发异常

  }
}

迄今为止采取的方法

1. 已禁用 NODE_TLS_REJECT_UNAUTHORIZED
2. 在选项中设置隧道（在GotImpl.ts中）

const tunnel = require('tunnel');
this.tunnelingAgent = tunnel.httpOverHttps({
            proxy: { // Proxy settings
                host: process.env.PROXY_HOST, // Defaults to 'localhost'
                port: process.env.PROXY_PORT, // Defaults to 80  
                proxyAuth: process.env.PROXY_AUTH,
            }
        });

this.options.agent = {};
this.options.agent.https = this.tunnelingAgent;
