lua-resty-tencent-cos-signature

Overview

This library implements request signing using the Tencent QCloud Signature XML Version specification. We can use this signature to request objects from COS an proxy them with Nginx (Openresty or lua-nginx-module).

这个库用于生成腾讯云 COS 对象储存的请求签名 (XML version)，故可用于配置 Nginx (需要安装 Openresty 或者编译 lua-nginx-module) 反代理私有仓库。

Usage

This library uses environment variables as credentials.

使用以下环境变量定义 ACCESS_KEY_ID 和 SECRET_ACCESS_KEY。

export COS_ACCESS_KEY_ID=AKIDEXAMPLE
export COS_SECRET_ACCESS_KEY=AKIDEXAMPLE

To be accessible in your nginx configuration, these variables should be declared in nginx.conf file.

之后还需要在 nginx.conf 中声明。

#user  nobody;
worker_processes  1;

pid logs/nginx.pid;

env COS_ACCESS_KEY_ID;
env COS_SECRET_ACCESS_KEY;

# or specify them in Nginx config file only
#env COS_ACCESS_KEY_ID=AKIDEXAMPLE;
#env COS_SECRET_ACCESS_KEY=AKIDEXAMPLE;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /dev/stdout;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

You can then use the library to add COS Signature headers and proxy_pass to a given COS bucket.

之后就可以在 server 块中添加配置了。

server {
  listen 80 default_server;

  set $cos_bucket 'example-1200000000';
  set $cos_host $cos_bucket.cos.ap-hongkong.myqcloud.com;

  location / {
    resolver 127.0.0.53 valid=300s;
    resolver_timeout 10s;

    rewrite (.*) /$1 break;

    access_by_lua_block {
      require("resty.cos-signature").cos_set_headers()
    }

    proxy_set_header Host $cos_host;
    proxy_pass http://$cos_host;
  }
}

It is recommend to install script with OPM.

建议用 OPM 安装。
