}
}
已经配置了这段代码，但是依旧提示跨域问题
Access to XMLHttpRequest at 'https://xxx.com/activity/faceCompare' from origin 'https://bb.xxx.com' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values 'https://bb.xxx.com, *', but only one is allowed.
求解决方案，谢谢

The 'Access-Control-Allow-Origin' header contains multiple values 'https://bb.xxx.com, *', but only one is allowed。这不是说只允许一个你配了俩？

mifar OP @Kyle18Tang 所以 Nginx 配置没问题是，是前端地址配置多了么？

看情况是多配置了一个，我之前遇到过类似的，是因为有多层 nginx，然后有两层都配置了 add_header，就会出现这种情况，不知道你这个是不是？可以先把你自己设置的去掉，然后发个 options 请求看下响应头

@mifar #2 你 location 外层是不是也配了 add_header?

可以看出你的 origin 里包含了*和域名，域名现在看不出来哪里加的。
你可以考虑先去掉 nginx 的这一条，如果能正常访问，你就要找这个域名是哪里加上去的。 btw，可能是前端开发环境影响？ |

kimchan 2019-01-25 09:13:07 +08:00
额.. 难道不是因为 allow-origin 配的"*" 的缘故吗? 你试试把 * 改成单域名试试?

这种情况是你配了两个一样的 header，我以前遇到过，我在 php 中输出了 header，结果测试环境的 nginx 也有人配置了跨域，就会报这个

都是直接后端进行这个配置。。

yc8332 2019-01-25 09:58:58 +08:00
还有一种情况是，配置* 是不行的。。。有些必须要具体域名，不能*
