從邏輯應用中的響應中獲取 cookie 數據

Question

在 postman 中，我可以看到我的 cookies 及其附加值：

當我在邏輯應用程序中運行帖子時，我得到了回復並且它有效。 問題是我不知道如何從響應中獲取 cookie 值，因為我在響應中看不到它。 我想知道如何從我的 HTTP 響應中獲取我的 cookie 值。

試試這個尺寸。

在 Azure 門戶中，使用 .NET 堆棧創建一個新的 HttpTrigger Azure Function 並使用此代碼將其稱為 HttpProxy ，請注意此代碼應該適用於您，但如果您希望 8830603067s7488 超出范圍，則可能需要進行調整...

現在在 LogicApps 中，添加您在上一步中創建的Azure Functions操作和 select HttpProxy function。

對於正文，您現在需要（首先調整）將 this 作為正文傳遞，並將 select POST作為方法傳遞...

{
  "url": "https://yoururl.com",
  "method": "POST",
  "headers": [
    {
      "key": "Username",
      "value": "YourUsername"
    },
    {
      "key": "Password",
      "value": "YourPassword"
    }
  ]
}

執行時，將產生一個結果，該結果在響應中也包含 cookies。 您會發現響應的正文包含在Body參數中，您可以提取和解析它。

這是我撥打我公司暴露的URL的例子...

... 是的，那里有很多，但這是結果，如您所見，響應底部有一個 cookies 數組，所有標頭和響應正文...
