關於nginx如何配置多域名【http或https跨域】跨域【注意：*通配符所有域名跨域有時候不會生效,建議使用指定多域名跨域配置】

重點nginx跨域參考：https://www.cnblogs.com/gaoyuechen/p/12880939.html

 

務必注意：add_header Access-Control-Allow-Origin *; 通配符配置所有的域名跨域在nginx會無效,多次測試依然如此，建議使用指定多域名跨域！

 

【我跨域成功的配置】指定多域名配置跨域：

		#使用正則表達式配置多個域名跨域信息【nginx配置*全部域名跨域不安全,也不建議使用,其次本人配置全部跨域一直未成功,具體原因還未知...】
				set $cors_origin "";
				if ($http_origin ~* "^https://aaaa.org$") {
						set $cors_origin $http_origin;
				}
				if ($http_origin ~* "^https://www.aaaa.org$") {
						set $cors_origin $http_origin;
				}
				# http或https跨域必須配置的三條記錄！
				add_header Access-Control-Allow-Origin $cors_origin;
				add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
				add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
