Tencent Cloud Serverless

对于中国用户，若需自行部署，目前作者找到的较好方案是腾讯云的 Serverless 云函数：

• 新用户前三个月免费
• 假设每月调用 30 次，每次 60 分钟，流量共 300M，则费用约为 1 元
• 实测单程延迟（client -> host）约为 35ms

腾讯云 Serverless 云函数部署步骤

部署步骤：

1. 打开腾讯云 Serverless 云函数（不是 Serverless Container）

2. 新建函数，选择以下配置：

• 创建方式：从头开始
• 函数类型：Web函数
• 运行环境：Go 1
• 函数代码：选择“本地上传 zip 包”，上传 serverless.zip
• 高级配置：
  • 内存：64MB
  • 请求多并发：自定义静态并发，设置为 100
  • WebSocket 支持：启用，空闲时间设置为 120 秒
• 函数 URL 配置：开启公网访问

3. 部署完成后，进入“函数 URL”栏目，复制公网访问的 wss:// 地址。在 VSCode 中点击 Share 后，填入该地址即可。
