How to configure multiple WeChat under Nginx reverse proxy port 80

nginx reverse proxy configures multiple WeChat projects under an 80 port Detailed explanation

If we want to access the WeChat public account platform for development, we need to fill in the server configuration and then implement it according to the interface document Business logic. However, the WeChat official account interface only supports interface 80 (port 80). Due to business needs, we need to publish two projects that require WeChat authorization under one official account domain name. What should we do?

We can use nginx server as a reverse proxy to solve this problem. The nginx server externally accesses port 80, and then accesses different projects internally based on different url parameters.

　

The nginx configuration is as follows:

Open /usr/local/nginx/conf/nginx.conf

worker_processes 4;
error_log logs/error.log;
events {
  worker_connections 1024;
}
http {
  include    mime.types;
  default_type application/octet-stream;
  sendfile    on;
  keepalive_timeout 65;

gzip on;
gzip_min_length 1k;
gzip_buffers 16 64k;
gzip_http_version 1.1;
gzip_comp_level 6;
gzip_types text/plain application/x-javascript text/css application/xml application/javascript;
gzip_vary on;

  #指向项目一

    server 192.168.1:8081;
  }
  #指向项目二

  }
  proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache:128m inactive=1d max_size=1g;
  include vhosts/*;
}
