如何在 cypress 中测试错误请求

我正在使用不正确的凭据测试 cypress 中的 POST 方法的日志记录。这会返回 400 个错误请求，我需要对其进行测试。

这就是我所拥有的：

describe('Login API Test - Correct user login', () => {
  it('Validate the header', () => {
    cy.request({
      method: 'POST',
      url: 'https://myrAPI',
      auth: {
        username: 'user@user',
        password: 'user123',
      },
      headers: {
        'Authorization': 'Basic dXNlckB1c2VyOnVzZXI=',
        'Content-Type': 'text/plain'
      }
    }).then((response) => {
      // expect(response.body).to.exist // true
      // expect(response.body).('User.Access: Exception occured:User.Access : CheckUser: Exception occurred:Error with Authentication Header. result =') // true
      // expect(response.headers).should.contain('text/plain; charset=utf-8')
      // expect(response.body).statusCode.should.equal(400)
      response.status.should.equal(400)
      //expect(response).to.have.property('headers')
    })
  }})

发送的请求：

Method: POST
URL: https://myapi
Headers: {
  "Connection": "keep-alive",
  "Authorization": "Basic dXNlckB1c2VyOnVzZXIxMjM=",
   "Content-Type": "text/plain",
   "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 
(KHTML, like Gecko) Chrome/75.0.3770.100 Safari/537.36",
  "accept": "*/*",
  "accept-encoding": "gzip, deflate",
  "content-length": 0
  }

这是我得到的回应：

Status: 400 - Bad Request
 Headers: {
  "content-length": "239",
   "content-type": "text/plain; charset=utf-8",
 "request-context": "appId=cid-v1:d994e38c-9493-4dd6-ac8c-5395bb9ce790",
   "date": "Tue, 02 Jul 2019 13:35:18 GMT"
}
 Body: User.Access: Exception occured:User.Access : CheckUser: Exception occurred:Exception when checkin...

我想知道响应或正文中的内容

您的问题的答案在错误消息中：

如果您不希望状态代码导致失败，请传递选项：'failOnStatusCode: false'

So pass failOnStatusCode: false为了不因错误状态代码而失败：

    cy.request({
        method: 'POST',
        url: 'https://myrAPI',
        failOnStatusCode: false,
        auth:
        {
            username: 'user@user',
            password: 'user123',
        },
        headers:
        {
            'Authorization': 'Basic dXNlckB1c2VyOnVzZXI=',
            'Content-Type': 'text/plain'
        }
    })
