POST 請求 cypress for 循環

Question

我正在編寫一個腳本來測試自動。 首先，我創建了一批隨機物品。 之后我發出一個 POST 請求。 一切正常，但 POST 請求一直提供相同的數據。 但是我的控制台打印了其他數據。

有人知道我做錯了什么嗎？ 在 for 循環中執行 POST 請求可能是不可能的嗎？

For 循環不能很好地與cy.request()等異步命令配合使用，但如果不運行它，我希望您的代碼能夠正常工作。

一個快速嘗試的技巧是將cy.request()包裝在 cy.then( cy.then()中。 這會延遲請求設置，並希望每次都能為您提供正確的copyShipment值。

...
cy.log(JSON.stringify(copyShipment))

cy.then(() => {
  cy.request({
    method: 'POST',
    url: '<url>',
    headers: {
      ...
    },
    body: copyShipment
  })
  .should(...)
})
