与无服务器结合使用时，NestJs Body() 不会填充请求信息

Question

当运行 SLS Offline 或 SLS Deploy 时，nest 中的主体装饰器未填充传递的对象。

我已经收集了一个小的 repo 来为任何感兴趣的人调查这个问题。

所以

经过大量探索 - 我仔细检查了传入请求

中的 headers

关于来自美联储的传入 POST 请求 - 仔细检查您正在设置 headers - 不像我那样节省几个小时 :)

    headers: {
        "Content-Type": "application/json"
    },

与无服务器结合使用时，NestJs Body() 不会填充请求信息

NestJs Body() is not populating with request information when coupled with serverless

serverless

nestjs
