ASP.NET Core Web API 无法在 Azure 上运行

Question

我对这个主题很陌生，但我已经使用 .Net 5 编写了一个 ASP.NET Core Web API。这个 API 只是读取和写入值到天蓝色数据库。它在我的机器上工作得很好，但是在 upload/publish 到 Azure 之后我得到一个“500 - 内部服务器错误”

{ 
"statusCode": 500, 
"message": "Internal server error", 
"activityId": "15ed7068-cb40-4e79-8205-cc4c6d4be8be" 
}

我已经按照 Microsoft 文档发布了我的 API：https://docs.microsoft.com/en-us/aspnet/core/tutorials/publish-to-azure-api-management-using-vs?view=aspnetcore-5.0

一旦我到达 https://docs.microsoft.com/en-us/aspnet/core/tutorials/publish-to-azure-api-management-using-vs?view=aspnetcore-5.0 这一步，它就不再起作用了。这是踪迹：

我已经尝试制作一个全新的项目并重新发布那个项目，但没有成功。

我有同样的问题，我通过将端口从 80 更改为 443（如果您使用 HTTPS）解决了这个问题。希望它能帮助你。或者你可以参考这个 https://github.com/ThreeMammals/Ocelot/issues/912
