func (*Client) Proxy

func (c *Client) Proxy(proxyURL string) *Client

Proxy is a chaining function, which sets proxy for next request. Make sure you pass the correct `proxyURL`. The correct pattern is like `http://USER:PASSWORD@IP:PORT` or `socks5://USER:PASSWORD@IP:PORT`. Only `http` and `socks5` proxies are supported currently.

Example

ExampleClientChain_Proxy a chain version of example for `gclient.Client.Proxy` method. please prepare two proxy server before running this example. http proxy server listening on `127.0.0.1:1081` socks5 proxy server listening on `127.0.0.1:1080` for more details, please refer to ExampleClient_SetProxy
