以下是nginx.conf的一个例子：

server \{

listen       8040;  
        server\_name  localhost;  
  
  
        \#charset koi8-r;  
  
  
        \#access\_log  logs/host.access.log  main;  
  
  
        location / \{     
            root   D:/Users/Administrator/workspace;  
            index  index.html index.htm;  
        \}  
  
location /files/ \{  
            root   D:/statusfile/data;  
            index  index.html index.htm;  
        \}  
  
location /data/ \{  
            root   D:/statusfile/data;  
            index  index.html index.htm;  
        \}  
  
  
location /check/ \{  
add\_header Access-Control-Allow-Origin \*;  
         add\_header Access-Control-Allow-Headers X-Requested-With;  
         add\_header Access-Control-Allow-Methods GET,POST,OPTIONS;  
         proxy\_set\_header X-Real-IP $remote\_addr;  
         proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
           proxy\_pass http://10.10.1.77:8088;

location / \{     
            root   D:/Users/Administrator/workspace;  
            index  index.html index.htm;  
        \}

当访问的地址是http://localhost:8040/index.html的时候 ，实际上是访问D:/Users/Administrator/workspace/index.html

location /files/ \{  
            root   D:/statusfile/data;  
            index  index.html index.htm;  
        \}

当访问的地址是http://localhost:8040/files/upload/sheet/201707251516571.png的时候，实际上是访问D:/statusfile/datafiles/upload/sheet/201707251516571.png

location /check \{  
 add\_header Access-Control-Allow-Origin \*;  
         add\_header Access-Control-Allow-Headers X-Requested-With;  
         add\_header Access-Control-Allow-Methods GET,POST,OPTIONS;  
         proxy\_set\_header X-Real-IP $remote\_addr;  
         proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
           proxy\_pass http://10.10.1.77:8088;

proxy\_pass: nginx的代理转发

当访问的地址是http://localhost:8040/check的时候，实际上是访问http://10.10.1.77:8088/check

add\_header Access-Control-Allow-Origin \*;  
         add\_header Access-Control-Allow-Headers X-Requested-With;  
         add\_header Access-Control-Allow-Methods GET,POST,OPTIONS;  
         proxy\_set\_header X-Real-IP $remote\_addr;  
         proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;

以上的配置为跨域的配置。

注意：location 后面那个虚拟路径的配置location /files/  location /check这些 必须是捕获访问路径的第一级，就是端口号后面接着的路径，不能捕获第二级或者之后的。
