409

我的表單可以在我的電腦上的 Brave 中運行,但不能在我的電腦上的 Safari 或 Google 中運行。它也不適用於行動裝置。如果它不起作用,它會傳回 POST 409 錯誤。

這是我的 html 程式碼。

<div class="row">

不同的瀏覽器之間經常存在差異,有些瀏覽器比其他瀏覽器更寬容。像這樣的錯誤通常是由於某些內容無法正確呈現(因此您的程式碼無法找到正確的欄位等)。要檢查 HTML,請透過 w3c 驗證器運行它並查看它的建議。

如果這沒有幫助,那麼要準確查看每個瀏覽器發送和接收的內容,我建議使用中間人代理(例如 burp) 攔截請求和回應。透過查看原始數據,通常很快就能看出問題所在。
