It is recommended to add a timeout option to the client code in the quick start of the sofa-rpc official website document.

建议 sofa-rpc 官网文档 快速开始 中Client代码增加超时选项

• 官网文档 快速开始
• 这个文档中client的代码没有.setConnectTimeout() 导致有可能跑demo的时候超时导致提示服务不可用

• 而github中对应demo的client代码中含有.setConnectTimeout()
• 建议将官网代码添加setConnectTimeout

Start with the linked SOFA-RPC website Quick Start section, specifically the client implementation, and compare it with the corresponding GitHub demo client mentioned in the issue. Update the website example to include the timeout option, then verify that the documented client matches the demo and avoids the reported connection-timeout failure.
