nginx根据url参数动态代理

nginx根据url参数动态代理

请求url格式，其中参数proxy后面的url就是需要访问的真实地址：
http://localhost:9388/?proxy=http://localhost:8038/Content/layui/font/iconfont.woff?v=256
http://localhost:9388/?proxy=http://localhost:8072/article/ArticleInfo/12309f4e71be45bf943f5b1346162e42
http://localhost:9388/?proxy=http://localhost:8038/user/login
http://localhost:9388/?proxy=http://99.89.11.137:8833/
