Question

我正在尝试获取当前url并希望将其存储为字符串但是.then总是返回undefined。以下是功能代码：

navigateToLandingPage() {
          let EC = protractor.ExpectedConditions;
          let currentURL: string;
          browser.getCurrentUrl().then ( (url) => {
            currentURL = url;
          } );
          if (currentURL !== 'operator') {
           browser.get('localhost:3000/#/operator');
           browser.wait(EC.urlContains('/operator'), 10000);
      }

我用这种方式称它为表单规范：

describe('Checking Module', () => {
  let page: CalendarModule;
  let EC = protractor.ExpectedConditions;
  beforeEach(() => {
    page = new CalendarModule();
  });
  it('Clicking on Calendar should redirect to Calendar Module', () => {
      page.commonMethodObj.navigateToLandingPage();
      let calendarLink = page.getCalendarLink();
       calendarLink.click().then(() => {
       browser.wait(EC.urlContains('/calendar'), 50000);
       expect(browser.getCurrentUrl()).toMatch('/calendar');
      });
  });
});

我正在使用以下版本的依赖项：

"@angular/core": "2.3.1",
"jasmine-core": "2.5.2",
"jasmine-spec-reporter": "2.5.0",
"protractor": "~4.0.13"

代码执行的整个行为和流程是异步并由WebDriver Control Flow编排。换句话说，您不能指望currentURL变量实际上会获得此行中的当前网址值：

if (currentURL !== 'operator') {

相反，在回调中工作：

browser.getCurrentUrl().then ( (currentURL) => {  
    if (currentURL !== 'operator') {
        browser.get('localhost:3000/#/operator');
        browser.wait(EC.urlContains('/operator'), 10000);
    }
});

量角器：browser.getCurrentUrl（）。then（（url）=＆gt; {return url;}）;总是返回undefined
