CY请求重试

Question

我正在尝试创建一条电子邮件服务，CY请求将获取并返回电子邮件的正文，但是从逻辑上讲，可能没有立即到达电子邮件，所以我认为正确的方法是每3秒获取一次，并且如果没有电子邮件尝试再次获取，因此基本上一遍又一遍地重试同样的操作，以便说每3秒钟2分钟。柏树在API中是否有东西？

it('Should be able to reset password', () => {
         let emailContent: string = '';
         cy.request(
          'GET',
          `https://api.testmail.app/api/json?apikey=${TestMailService.APIKEY}&namespace=${TestMailService.NAMESPACE}&tag=test&livequery=true`,
        ).then((response) => {
            emailContent =  response.body.emails[0].text;
        });
      })

从文档请求投票

// a regular ol' function folks
function req () {
  cy
    .request(...)
    .then((resp) => {
      // if we got what we wanted

      if (resp.status === 200 && resp.body.ok === true)
        // break out of the recursive loop
        return

      // else recurse
      req()
    })
}

这是一个递归功能，所以我会我在无限呼叫的情况下添加警卫（没有显示电子邮件）。

等待3秒只是cy.wait（3000）

// a regular ol' function folks
function req (attempts = 0) {

  if (attempts === 100) throw 'Too many attempts'

  cy.request(...)
    .then((resp) => {
      // if we got what we wanted

      if (resp.status === 200 && resp.body.ok === true)
        // break out of the recursive loop
        return

      // else recurse
      cy.wait(3000)
      req(++attempts)
    })
}

传递特定电子邮件主题

// TestMailService class

static getLatestEmail(subject: string, attempts = 0): string {

  const NAMESPACE: string = '...';
  const APIKEY: string = '...';

  if (attempts === 40) throw 'No email reached within 2 minutes ';

  return cy.request('GET',         // return the async request
    `api.testmail.app/api/…${APIKEY}&namespace=${NAMESPACE}&tag=dev`)
    .then((response) => {

      if (response.body.emails.length != 0) {
        response.body.emails.forEach((email: any) => {
          if (email.subject === subject) {
            return email.text;       // this modifies what request returns
          }
        });
      }
      if (response.body.emails.length === 0) {
        cy.wait(3000);
        // another return here passes inner results outwards
        return TestMailService.getLatestEmail(subject, ++attempts);   
      }
    })
}

...

TestMailService.getLatestEmail('Registration').then(emailBody => {
  ...
})
