NgInx作为Kong的反向代理 [英] NgInx as reverse proxy with Kong

问题描述

我想使用Kong作为在Docker容器中运行的API网关.每个请求必须首先通过NgInx服务器，如果请求的uri与example.com/api相匹配，则必须生成在Kong内注册的api.

I wanna use Kong as my API Gateway, running in a Docker container. Each request must go first through a NgInx server and if the requested uri matches example.com/api it must result in the api, registered inside Kong.

为此，我已使用以下命令将API添加到Kong:

To achieve this I've added my API to Kong with the following command:

curl -i -X POST --url ipnumber:8001/apis -d 'name=my-api' -d `enter code here`'upstream_url=http://httpbin.org' -d 'hosts=example.com' -d 'uris=/api/my-api'

通过执行以下命令，我会得到正确的答案，所以我认为Kong可以正常工作.

By executing the following command I get the correct answer, so I suppose Kong is working correctly.

curl -i -X GET --url ipnumber:8000/api/my-api --header 'Host: example.com'

我的NgInx配置如下:

My NgInx configuration looks like this:

upstream kong {
  server 127.0.0.1:8000;
}

location /api {
   proxy_pass: http://kong;
}

在我的主机文件中，我已使用example.com域配置了NgInx服务器的IP.

In my host file I've configured the IP of the NgInx server with the domain example.com.

问题是:当我浏览到example.com/api/my-api甚至example.com/my-api时，结果是NgInx的404错误页面.

The problem is: when I'm browsing to the example.com/api/my-api or even example.com/my-api the result is a 404 error page of NgInx.

当我浏览到ipnumber:8000/api/my-api时，它会显示一条消息，说Kong没有匹配给定值的api，这是正确的，因为主机名不是example.com

When I browse to ipnumber:8000/api/my-api it results in a message of Kong saying there's no api matching the given values, which is correct because the hostname isn't example.com

很长一段时间以来，我一直在寻找这个问题，但是我无法解决它.我也在寻找 https://getkong.org /docs/0.10.x/configuration/#custom-nginx-configuration-embedding-kong ，但由于我已经拥有自己的nginx配置，因此我不确定是否必须这样做.

I'm looking to this problem already a long time but I have not been able to fix it. I was looking also to https://getkong.org/docs/0.10.x/configuration/#custom-nginx-configuration-embedding-kong but I'm not sure if I have to do it that way because I've already my own nginx configuration.

在此先感谢您的反馈.

推荐答案

您需要告诉NGINX将Host标头转发到Kong.您可以像这样使用proxy_set_header来做到这一点:

You need to tell NGINX to forward the Host header upstream to Kong. You can do that with proxy_set_header like so:

location /api {
   proxy_pass: http://kong;
   proxy_set_header Host $host;
}
