What are Nginx proxy axios requests and precautions?

1. nginx.conf configuration information

Since nginx.conf has a lot of configuration information, this article only focuses on axios and static resource request settings, and will also cover common Note some configuration items. The specific settings are as follows:

# 设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
 #连接超时时间
 keepalive_timeout 120;
 
 #gzip压缩开关及相关配置
 gzip on;
 gzip_min_length 1k;
 gzip_buffers  4 32k;
 gzip_http_version 1.1;
 gzip_comp_level 2;
 gzip_types  text/plain application/x-javascript text/css application/xml;
 gzip_vary on;
 gzip_disable "msie [1-6].";

 #设定实际的服务器列表 
 upstream zp_server{
 server 127.0.0.1:8089;
 }
 
 #http服务器 
 server {
 #监听80端口
 listen 80
 
 #定义服务名称
 server_name localthost;
 
 #首页
 index index.html
 
 #指向项目根目录
 root d:\project\src\main\webapp;
 
 #编码格式
 charset utf-8;
 
 #代理的路径（和upstream绑定），location 后面设置映射的路径
 location / {
  #代理配置参数
  proxy_connect_timeout 180;
  proxy_send_timeout 180;
  proxy_read_timeout 180;
  proxy_set_header host $host;
  proxy_set_header x-forwarder-for $remote_addr;
  proxy_pass http://zp_server/;
  
  #跨域相关设置
  add_header 'access-control-allow-origin' '*' always;
  add_header 'access-control-allow-credentials' 'true';
  add_header 'access-control-allow-headers' 'origin, x-requested-with, content-type, accept' always;
  }
  
  #配置静态资源 解决js css文件无法加载无法访问的问题，注意末尾不能有 /
  location ~ .*\.(js|css|jpg|png)$ {
  proxy_pass http://zp_server;
  } 
 }
}

2. The slash problem of proxy_pass

##nginx divides proxy_pass into two types:

• One type only contains the ip and port number (not even the / after the port, special attention should be paid here), such as proxy_pass http://localhost:8080, this method is called the without uri method;

• The other one has other paths after the port number, including those with only a single /, such as proxy_pass http://localhost:8080/, and other paths, such as proxy_pass http ://localhost:8080/abc.

2.1 For the method without uri

For the method without uri, nginx will retain the path part of the location, for example:

location /api1/ {
 proxy_pass http://localhost:8080;
}

When accessing http://localhost/api1/xxx, it will be proxy to http://localhost:8080/api1/xxx

2.2 For the uri method

For the uri method, nginx will use replacement methods such as alias to replace the url, and this replacement is only a literal replacement, such as:

location /api2/ {
 proxy_pass http://localhost:8080/;
}

When accessing http When ://localhost/api2/xxx, http://localhost/api2/ (note the / at the end) is replaced by http://localhost:8080/, and then the remaining xxx is added, so it becomes http://localhost:8080/xxx.

2.3 Summary

server {
 listen    80;
 server_name localhost;

 location /api1/ {
  proxy_pass http://localhost:8080;
 }
 # http://localhost/api1/xxx -> http://localhost:8080/api1/xxx


 location /api2/ {
  proxy_pass http://localhost:8080/;
 }
 # http://localhost/api2/xxx -> http://localhost:8080/xxx


 location /api3 {
  proxy_pass http://localhost:8080;
 }
 # http://localhost/api3/xxx -> http://localhost:8080/api3/xxx


 location /api4 {
  proxy_pass http://localhost:8080/;
 }
 # http://localhost/api4/xxx -> http://localhost:8080//xxx，请注意这里的双斜线，好好分析一下。


 location /api5/ {
  proxy_pass http://localhost:8080/haha;
 }
 # http://localhost/api5/xxx -> http://localhost:8080/hahaxxx，请注意这里的haha和xxx之间没有斜杠，分析一下原因。

 location /api6/ {
  proxy_pass http://localhost:8080/haha/;
 }
 # http://localhost/api6/xxx -> http://localhost:8080/haha/xxx

 location /api7 {
  proxy_pass http://localhost:8080/haha;
 }
 # http://localhost/api7/xxx -> http://localhost:8080/haha/xxx

 location /api8 {
  proxy_pass http://localhost:8080/haha/;
 }
 # http://localhost/api8/xxx -> http://localhost:8080/haha//xxx，请注意这里的双斜杠。
}
