死磕nginx系列--proxy_pass后端斜杠问题

Posted on Edited on In ,

假设nginx服务器的IP地址：192.168.56.11
当我们访问：http://192.168.56.11/test/test.html 时

如果proxy_pass 后端包含反斜线，后端服务器得到的URL为：192.168.56.12:8002/test.html
如果proxy_pass 后端不包含反斜线时，后端服务器得到的URL为：
192.168.56.12:8002/test/test.html

实例

proxy_pass 包含反斜线

}
http {
    include       mime.types;
    default_type  application/octet-stream;
