如何使用proxy_pass重写URI nginx反向代理? [英] How to rewrite URI nginx reverse proxy using proxy_pass?
问题描述
我正在尝试使用nginx将代理反向转换为运行各种Web应用程序的kubernetes pod.我的问题是，仅当位置设置为/而不是/someplace
I'm trying to use nginx to reverse proxy into kubernetes pods running various web apps. My issue is that I can only proxy when location is set to / and not /someplace
我知道内部IP正在工作，因为当我将它们与location /一起使用时，两个Web应用程序均成功加载，并且可以在内部卷曲网页.
I know the internal IPs are working because both web apps load successfully when I use them with location /, and I can curl the webpages internally.
我想发生的事情
http://ServerIP/app1 路由到 http://Pod1IP:3000 http://ServerIP/app2 路由到通过这种方式，我可以轻松地在同一端口上运行所有应用程序.
In this manner I could easily run all my apps on the same port.
我相信正在发生的事情 http://ServerIP/app1 -> httpL//Pod1IP:3000/app1
What I believe is happening http://ServerIP/app1 --> httpL//Pod1IP:3000/app1
我尝试通过重写如下所示的URI来解决此问题，当我尝试访问/app1
I tried solving this by doing a rewrite of the URI like below, that resulted in a blank page loading when I tried to access /app1
server {
listen 80;
location = /app1/ {
rewrite ^.*$ / break;
proxy_pass http://10.82.5.80:80;
}
location / {
proxy_pass http://10.106.228.213:15672;
}
}
有什么想法让我搞砸了吗?
Any ideas where I messed up?
我要使用的Web应用程序称为RabbitMQ UI.为了尝试调试我的情况，我卷曲了三个不同的URL，以查看nginx响应了什么.
The webapp I am trying to use is called RabbitMQ UI. To try and debug my situation I curled three different URLs to see what nginx was responding with.
卷曲/会加载正确的html页面，并且可以在浏览器中使用.
Curling the / loads the correct html page, and it works in the browser.
curl http://10.82.5.80/

卷曲/rabbitmq找不到返回或已永久移动
Curling /rabbitmq returns not found or Moved Permanently
curl http://10.82.5.80/rabbitmq

卷曲/rabbitmq/位置可提供正确的页面，但会在浏览器中加载空白.我认为这是因为浏览器无法引用html文档中存在的js文件?
Curling the /rabbitmq/ location gives the correct page, but loads a blank in the browser. I think this is because the browser cannot reference the js files present in the html doc?

推荐答案
尝试在您的代理位置中添加URL，如下所示:
Try adding the URL in your proxy location like this:
location = /app1/ {
proxy_pass http://10.82.5:80/;
}
在proxy_pass的末尾添加尾随/会强制nginx从请求中剥离/app1前缀，同时将其发送到后端.
Adding a trailing / at the end of the proxy_pass forces nginx to strip the /app1 prefix from your requests while sending it to the backend.
Explanation on how it works on the official nginx page: http://nginx.org/en/docs/http/ngx_http_proxy_module.html?&_ga=1.74997266.187384914.1443061481#proxy_pass
If the proxy_pass directive is specified with a URI, then when a request is passed to the server, the part of a normalized request URI matching the location is replaced by a URI specified in the directive:
