基于请求正文内容的nginx条件代理传递 [英] nginx conditional proxy pass based on request body content
本文介绍了基于请求正文内容的nginx条件代理传递的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
仅在$ request_body变量与特定正则表达式匹配时,我才尝试配置nginx代理将请求传递给另一台服务器.但这对我不起作用.
I am trying to configure nginx to proxy pass the request to another server, only if the $request_body variable matches on a specific regular expression.But it is not working for me.
server{
listen 80 default;
server_name www.applozic.com;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
if ($request_body ~* (.*)appId(.*)) {
proxy_pass http://apps.applozic.com;
}
}
}
请求正文是::
{
"applicationId": "appId",
"authenticationTypeId": 1,
"enableEncryption": false,
"notificationMode": 0,
"deviceType": 4,
}
推荐答案
我找到了解决方案.
我在nginx(打开Resty)配置文件中做了以下更改
I did following changes in nginx(open resty) config file
upstream algoapp {
server 127.0.0.0.1:543;
}
upstream main {
server 127.0.0.1:443;
}
location /rest/ws/login {
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Url-Scheme $scheme;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_redirect off;
if ($request_method = OPTIONS ) {
proxy_pass https://127.0.0.1:543;
}
if ($request_method = POST ) {
set $upstream '';
access_by_lua '
ngx.req.read_body()
local data = ngx.req.get_body_data()
local match = ngx.re.match(ngx.var.request_body, "appId")
if match then
ngx.var.upstream = "algoapp"
else
ngx.var.upstream = "main"
end
';
proxy_pass https://$upstream;
}
}
