【Nginx】Nginx location 中root alias error_page 404 路径部分是否/开头的理解

注意：路径中 所有// nginx已/处理 ， root和alias的区别请另百度一下

第一种 error_page 404 /开头，正常访问localhost:8080:work-order ，404访问localhost:8080:work-order/home

root

location ^~ /work-order/ {
   
        root   basePath/test/;
        index  index.html index.htm;
        error_page  404           /work-order/index.html;
      }
status 200: basePath/test//work-order//index.html 
status 404: basePath/test//work-order/index.html  /开头代表从basePath后开始替换

location ^~ /work-order/ {
        root   basePath/test/;
        index  index.html index.htm;
        error_page  404           /wen/index.html;
      }
status 200: basePath/test//work-order//index.html
status 404: basePath//wen/index.html  /开头代表从basePath后开始替换 注：此时访问的是localhost:8080:wen 匹配不到/work-order了

alias

location ^~ /work-order {
       alias   basePath/test/work/;
       index  index.html index.htm;
       error_page  404         /work-order/index.html;
     }
 
status 200: basePath/test//work//index.html
status 404: basePath/test//work/index.html  /work-order/index.html;  /开头代表从basePath后开始替换

location ^~ /work-order {
       alias   basePath/test/work/;
       index  index.html index.htm;
       error_page  404           /wen/index.html;
     }
 
status 200: basePath/test//work//index.html
status 404: basePath//wen/index.html   /开头代表从basePath后开始替换 注：此时访问的是localhost:8080:wen 匹配不到/work-order了

第二error_page 404 没有 /开头，访问localhost:8080:work-order，404访问localhost:8080:work-order/home

root

location ^~ /work-order/ {
   
        root   basePath/test/;
        index  index.html index.htm;
        error_page  404           work-order/index.html;
      }
status 200: basePath/test//work-order//index.html 
status 404: basePath/test//work-order/work-order/work-order/work-order/index.html   没有/开头表示相对路径  因为一直404所以/work-order/work-work-order/wen

location ^~ /work-order/ {
        root   basePath/test/;
        index  index.html index.htm;
        error_page  404           wen/index.html;
      }
status 200: basePath/test//work-order//index.html
status 404: basePath/test///work-order/wen/wen/wen/index.html 没有/开头表示相对路径  ,因为一直404所以/wen/wen/wen

alias

location ^~ /work-order {
       alias   basePath/test/work/;
       index  index.html index.htm;
       error_page  404     work-order/index.html
     }
 
status 200: basePath/test//work//index.html
status 404: basePath/test//work/work-order/work-order/work-order/index.html; 没有/开头表示相对路径,因为一直404所以/work-order/work-work-order/wen

location ^~ /work-order {
       alias   basePath/test/work/;
       index  index.html index.htm;
       error_page  404           wen/index.html;
     }
 
status 200: basePath/test//work//index.html
status 404: basePath/test//work//wen/wen/wen/wen/index.html   /开头代表从basePath后开始替换 因为一直404所以/wen/wen/wen
