从Protractor中的REST端点进行异步调用以获取测试数据的正确方法？

const { browser } = require('protractor');
const { protractor } = require('protractor/built/ptor');

describe('Test Suite', function() {
  let http;

  beforeAll(function() {
    http = browser.$http; // 导入$http服务
  });

  // 测试用例...
});

describe('Test Suite', function() {
  let http;

  beforeAll(function() {
    http = browser.$http;
  });

  it('should retrieve test data from REST endpoint', function() {
    const endpointUrl = 'https://example.com/api/data'; // REST端点的URL

    http.get(endpointUrl).then(function(response) {
      const testData = response.data; // 获取返回的测试数据
      // 对测试数据进行断言或其他操作
    });
  });
});
