CORS飞行前通道未成功

Question

我试图在本地构建一个用PHP REST框架作为我的api的Ember应用程序。Ember应用程序在http://localhost:4200提供，而api只在http://localhost提供。这导致了一个CORS问题。我已经尝试了我能想到的一切，但我不断得到一个错误返回，说请求被阻止，飞行前通道没有成功。它在Firefox或Chrome上都不成功。

我已经将以下内容添加到API的.htaccess文件中：

Header set Access-Control-Allow-Methods "GET, POST, OPTIONS"
Header set Access-Control-Allow-Origin "http://localhost:4200"
Header set Access-Control-Allow-Credentials true
Header set Access-Control-Allow-Headers "accept, content-type"

有什么想法或解决办法吗？任何帮助都很感激。谢了！

Answer 1

您的飞行前选项请求返回200吗？您可以尝试用您的.htaccess返回一个200响应，如下所示：

Header always set Access-Control-Allow-Methods "GET, POST, OPTIONS"
Header always set Access-Control-Allow-Origin "http://localhost:4200"
Header always set Access-Control-Allow-Credentials true
Header always set Access-Control-Allow-Headers "accept, content-type"

RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L]
