使用nginx，使用https进行访问ollama，并添加api-key的校验

1. 安装nginx

sudo apt install nginx

2. 自己申请https需要的key，修改nginx配置，增加如下配置

server {
        listen 443 ssl;
        server_name xx.xxx.com;
        
		#ssl证书配置
        ssl_certificate      /home/wei/pem/fullchain.pem;
        ssl_certificate_key  /home/wei/pem/privkey.pem;
        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;
        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;
        
 	# 反代到 Ollama API
    location / {
    	# Ollama 默认端口是 11434
        proxy_pass  http://localhost:11434;  
        # 请求时的origin请求头
        proxy_set_header origin http://localhost:11434;
        
        # 关闭 Nginx 的响应缓冲，强制数据实时传输到客户端
        proxy_buffering off;
        # 使用 HTTP/1.1 以支持长连接，避免 HTTP/1.0 的短连接问题
        proxy_cache off;
        # 确保流式传输的实时性
        proxy_set_header Connection '';
        proxy_http_version 1.1;
        # 关闭 Nginx 的分块编码处理（根据实际情况调整）
        chunked_transfer_encoding off;

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # 添加 CORS 头部
        add_header 'Access-Control-Allow-Origin' '*' always;
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
        add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization' always;
        add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range' always;
        
        set $auth_header $http_authorization;
        if ($auth_header != "Bearer sk-595b92eba33c4c1b91f08314abf21234") { 
            add_header 'WWW-Authenticate' 'Bearer realm="Access to the API"'; 
            return 401; 
        }

        # 处理预检请求 (OPTIONS)
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization';
            add_header 'Access-Control-Max-Age' 1728000;
            add_header 'Content-Type' 'text/plain; charset=utf-8';
            add_header 'Content-Length' 0;
            return 204;
        }
    }
}

其中这部分是对apikey进行验证，不匹配则返回

        set $auth_header $http_authorization;
        if ($auth_header != "Bearer sk-595b92eba33c4c1b91f08314abf21234") { 
            add_header 'WWW-Authenticate' 'Bearer realm="Access to the API"'; 
            return 401; 
        }

以上就兼容好了openai的api请求，本地将外网的8092转发到本地443端口，最终请求的url为

https://xx.xxx.com:8092/v1/

api key填写nginx 配置里的key
