我们要接入微信公众号平台开发，需要填写服务器配置，然后依据接口文档才能实现业务逻辑。但是微信公众号接口只支持80接口（80端口）。我们因业务需求需要在一个公众号域名下面，发布两个需要微信授权的项目，怎么办？
我们可以用nginx服务器做反向代理来解决这个问题。nginx服务器对外80端口，然后根据URL参数不同，对内访问不同的项目。
nginx配置如下：
打开/usr/local/nginx/conf/nginx.conf
1 worker_processes 4; 2 error_log logs/error.log; 3 events { 4 worker_connections 1024; 5 } 6 http { 7 include mime.types; 8 default_type application/octet-stream; 9 sendfile on; 10 keepalive_timeout 65; 11 12 gzip on; 13 gzip_min_length 1k; 14 gzip_buffers 16 64k; 15 gzip_http_version 1.1; 16 gzip_comp_level 6; 17 gzip_types text/plain application/x-javascript text/css application/xml application/javascript; 18 gzip_vary on; 19 20 #指向项目一 21 upstream backend1 { 22 server 192.168.1:8081; 23 } 24 #指向项目二 25 upstream backend2{ 26 192.168.1.1:8082; 27 } 28 proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache:128m inactive=1d max_size=1G; 29 include vhosts/*; 30 }
打开/usr/local/reverse_proxy_nginx/conf/nginx.conf
1 worker_processes 2; 2 events { 3 worker_connections 1024; 4 } 5 http { 6 include mime.types; 7 default_type application/octet-stream; 8 access_log /home/nginx_log/reverse_proxy_no1_access.log; 9 sendfile on; 10 keepalive_timeout 65; 11 upstream backend1 { 12 #server 192.168.1.1:8181; 13 server 192.168.1.1:8081; 14 } 15 upstream backend2 { 16 #server 192.168.1.1:8082; 17 server 192.168.1.1:8082; 18 } 19 proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache:128m inactive=30m max_size=1G; 20 server { 21 listen 8081; 22 server_name h5.xxxx.com; 23 24 location / { 25 proxy_pass http://backend1; 26 #Proxy Settings 27 proxy_redirect off; 28 proxy_set_header Host $host; 29 proxy_set_header X-Real-IP $remote_addr; 30 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 31 proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504; 32 proxy_max_temp_file_size 0; 33 proxy_connect_timeout 90; 34 proxy_send_timeout 90; 35 proxy_read_timeout 90; 36 proxy_buffer_size 4k; 37 proxy_buffers 4 32k; 38 proxy_busy_buffers_size 64k; 39 proxy_temp_file_write_size 64k; 40 add_header Nginx-Res "http://backend1"; 41 } 42 43 location ~ ^/(h5)(.*)$ { 44 proxy_pass http://backend2; 45 proxy_redirect off; 46 proxy_set_header Host $host; 47 proxy_cache cache; 48 proxy_cache_valid 200 302 1d; 49 proxy_cache_valid 301 1d; 50 proxy_cache_valid any 1m; 51 expires 1h; 52 add_header Nginx-Res "http://backend2"; 53 proxy_ignore_headers "Cache-Control" "Expires" "Set-Cookie"; 54 add_header Nginx-Cache "$upstream_cache_status"; 55 } 56 57 58 error_page 500 502 503 504 /50x.html; 59 location = /50x.html { 60 root html; 61 } 62 location ~ .*.(gif|jpg|png|css|js|ico)(.*) { 63 proxy_pass http://backend1; 64 proxy_redirect off; 65 proxy_set_header Host $host; 66 proxy_cache cache; 67 proxy_cache_valid 200 302 30d; 68 proxy_cache_valid 301 1d; 69 proxy_cache_valid any 1m; 70 expires 30d; 71 proxy_ignore_headers "Cache-Control" "Expires" "Set-Cookie"; 72 add_header Nginx-Res "http://backend1"; 73 add_header Nginx-Cache "$upstream_cache_status"; 74 }
当我们打开URL包含h5时，就会跳到8081端口项目中，但是对外还是80端口。所以两个项目可以同时实现微信授权登录等。
