在使用 curl 命令时，如果你需要通过代理服务器进行网络请求，可以使用 -x 或 --proxy 选项来指定代理服务器。下面是使用代理的一些基本示例：
使用 HTTP 代理
如果你的代理服务器是 HTTP 代理，你可以这样使用：
|
1 |
curl -x http://代理服务器地址:端口 http://目标网址 |
使用 HTTPS 代理
如果你的代理服务器支持 HTTPS，使用方法类似：
|
1 |
curl -x https://代理服务器地址:端口 https://目标网址 |
使用 SOCKS5 代理
curl 同样支持 SOCKS4 和 SOCKS5 代理，例如使用 SOCKS5 代理：
|
1 |
curl -x socks5://代理服务器地址:端口 http://目标网址 |
验证代理服务器
如果你的代理服务器需要认证，可以通过在代理地址前添加用户名和密码来实现：
|
1 |
curl -x http://用户名:密码@代理服务器地址:端口 http://目标网址 |
请将 代理服务器地址、端口、用户名、密码 和 目标网址 替换为实际使用的值。
使用配置文件
linux 下使用当前用户目录下的 .curlrc, Windows 下使用当前用户目录下的_curlrc
文件内容如下：
|
1 |
proxy=http://127.0.0.1:18081 |
注意事项
- 使用代理时，请确保代理服务器的地址和端口号正确无误。
- 如果代理服务器需要认证，请确保提供的用户名和密码正确。
- 有些网络环境可能会限制或阻止代理服务器的使用，请确保你有权使用指定的代理服务器。
这些是 curl 使用代理的基本方法，可以根据你的具体需求进行选择和调整。
例子
1. Windows 下获取OpenAI API 的模型列表，需要设置环境变量 OPENAI_API_KEY
|
1 |
curl -x http://127.0.0.1:18081 https://api.openai.com/v1/models -H "Authorization: Bearer %OPENAI_API_KEY%" |
2.linux 下获取OpenAI API 的模型列表，需要设置环境变量 OPENAI_API_KEY
|
1 |
curl -x http://127.0.0.1:18081 https://api.openai.com/v1/models -H "Authorization: Bearer $OPENAI_API_KEY" |
运行结果：

重定向使用 -L
在下载文件的时候，可能会有重定向发生，这个时候需要使用 -L 参数
