nginx 配置根据请求头分发问题

 location /aa { proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header X-real-ip $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; if ($http_environment_name = "loc" ) { proxy_pass http://127.0.0.1:28080; break; } if ($http_environment_name = "pro" ) { proxy_pass http://127.0.0.1:8011/api/; break; } proxy_pass http://127.0.0.1:8022/api/; }

以前写过一个判断是否移动端的，可以参考我这个写法：![]( https://tendcode.com/cdn/2024/202501131703259.png)

使用 map ,测试了一下没问题
```
# 根据请求头 environment_name 映射目标地址
map $http_environment_name $backend {
default http://127.0.0.1:8022/api/; # 默认地址
loc http://127.0.0.1:28080; # loc 的地址
pro http://127.0.0.1:8011/api/; # pro 的地址
}

server {
listen 80;

location /aa {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;

# 动态选择后端
proxy_pass $backend;
}
}
```

```
~ cat test_njet.sh 130 xtcc@xtcc-b560m-power
curl -H "environment-name: " http://127.0.0.1:8089/aa
curl -H "environment-name: ssss" http://127.0.0.1:8089/aa

写 map 设置变量值即可

要不你统一一下，
http://127.0.0.1:28080
http://127.0.0.1:8011/api/
http://127.0.0.1:8022/api/
在 api 后面去掉 /，

不然你替换后的路径看着有问题，会有两个 //

api//test 这样，可能有些语言会兼容，但是有些语言就直接报错。

proxy_pass api 后边不要加左斜杠，否则转发时会将 location 里的 /aa 去掉，实际转发到了 api/*** 而非/api/aa/***

@smallparking @guanzhangzhang 还是不太行，使用 map 配置 pro http://127.0.0.1:8011/api/;这种情况访问不通，只有 url 没/api/的是可以正常访问，还是统一一下/api 好些

发现 rewrite 可以解决
location /aa {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-real-ip $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
if ($http_environment_name = "loc" ) {
proxy_pass http://127.0.0.1:28080;
break;
}
if ($http_environment_name = "pro" ) {
rewrite ^/aa /(.*)$ /api/$1 break;
proxy_pass http://127.0.0.1:8011;
break;
}
proxy_pass http://127.0.0.1:8022/api/;
}

应该 map 也是可以的，发现 pro 服务有点问题，没重新试，当前用 rewrite
