Setup

设置

In most cases, LocalSend should work out of the box. However, if you are having trouble sending or receiving files, you may need to configure your firewall to allow LocalSend to communicate over your local network. 在大多数情况下，LocalSend 开箱即用。但是，如果您在发送或接收文件时遇到问题，可能需要配置防火墙以允许 LocalSend 在本地网络上进行通信。

Also make sure to disable AP isolation on your router. It should be usually disabled by default but some routers may have it enabled (especially guest networks). 此外，请确保关闭路由器上的 AP 隔离（AP Isolation）。该功能通常默认关闭，但某些路由器（尤其是访客网络）可能会将其开启。

How It Works

工作原理

LocalSend uses a secure communication protocol that allows devices to communicate with each other using a REST API. All data is sent securely over HTTPS, and the TLS/SSL certificate is generated on the fly on each device, ensuring maximum security. LocalSend 使用一种安全通信协议，允许设备通过 REST API 相互通信。所有数据均通过 HTTPS 安全传输，且 TLS/SSL 证书在每台设备上即时生成，从而确保了最高级别的安全性。

Troubleshooting

故障排除

If your device is not visible, make sure to disable AP-Isolation on your router. If you are on Windows, ensure your network is configured as a “private” network, as Windows might be more restrictive when the network is configured as public. 如果您的设备不可见，请确保关闭路由器上的 AP 隔离。如果您使用的是 Windows，请确保将网络配置为“专用”网络，因为当网络配置为“公用”时，Windows 的限制可能会更严格。
