“Access-Control-Allow-Origin"标头的值不等于提供的原点 [英] The 'Access-Control-Allow-Origin' header has a value that is not equal to the supplied origin

问题描述

我正在尝试使用 ajax 登录 API，但出现此错误:

I am trying to login with ajax to an API and I get this error:

XMLHttpRequest 无法加载.'Access-Control-Allow-Origin' 标头具有不等于提供的原点的值.起源'http://localhost' 因此不允许访问.

XMLHttpRequest cannot load. The 'Access-Control-Allow-Origin' header has a value that is not equal to the supplied origin. Origin 'http://localhost' is therefore not allowed access.

我在互联网上阅读了有关此错误的所有信息，并且尝试了所有可以在网上找到的解决方案.我根据此处的 CORS 说明修改了 .htaccess 和 apache httpd 配置文件:http://enable-cors.org/server_apache.html

I read all about this error, all over the internet, and I've tried all the solutions I could find online. I modified the .htaccess and apache httpd configuration file according to the CORS instructions here: http://enable-cors.org/server_apache.html

Access-Control-Allow-Origin: *

似乎没有任何效果.如果你们能帮我解决这个问题，我真的很感激.谢谢！

Nothing seems to be working. I'd really appreciate if you guys can help me out with this. Thank you!
