resty_functions/file_upload

部署文件上传功能

• 配置openresty

  # 配置文件路径
  # /usr/local/openresty/nginx/conf/nginx.conf
  # http contex 中添加lua脚本的路径
  lua_package_path "/usr/local/openresty/resty_funcs/?.lua;;";
  

  # 子域名配置文件路径
  # /usr/local/openresty/nginx/conf.d/music-room.conf
  
  # server contex 中添加文件存储路径变量
  set $store_dir "/file_upload/"; # 文件存储路径
  
  # server contex 中添加location
  # Test location
  location /test_hello_world {
      #设置content type
      default_type text/html ;
      # HTTP Status Code 和 内容
      return 200  "hello world! ";
  }
  
  # Upload dir
  location /append_file_output {
    default_type "";
    alias /file_upload;
    autoindex on;
    autoindex_exact_size off;
    autoindex_localtime on;
  }
  
  # Upload image file
  location /upload_image {
    content_by_lua_file /usr/local/openresty/resty_funcs/upload_image.lua;
  }
  

• 添加lua脚本

  将file_upload文件夹下的所有文件copy到如下路径

  /usr/local/openresty/resty_funcs
  .
  ├── redis.lua
  ├── upload_image.lua
  ├── upload.lua
  └── uuid.lua
  

• 重启服务

  $ sudo openresty -t
  nginx: the configuration file /usr/local/openresty/nginx/conf/nginx.conf syntax is ok
  nginx: configuration file /usr/local/openresty/nginx/conf/nginx.conf test is successful
  #首先要openresty nginx配置文件无误
  $ sudo systemctl restart openresty
  #重启openresty服务不报错
  

• 测试curl命令

  curl -v -F 'up_load_json=@./test_files/test0.jpg' -F 'up_load_json=@./test_files/test1.jpg' -F 'up_load_json=@./test_files/test2.jpg' https://music-room.alchemy-studio.cn/upload_image
  

  ⚠️ ./test_files/test0.jpg ./test_files/test1.jpg ./test_files/test2.jpg 为三张上传拼接的图片的路径和文件名
