我有一个部署到 Azure 应用服务 (Linux) 的 ASP.NET Core 2.2 应用。我无法查看应用程序的 Web 服务器日志(HTTP 流量)。
Microsoft 支持建议 HTTP 流量应该在 xx_default_docker.log 文件中可见，但事实并非如此。我已经验证应用程序可以记录，因为我的应用程序日志存在。
docker 启动还表明 HTTP 日志记录已启用。 default_docker.log 如下所示。
2019-08-22 13:54:56.855 INFO - docker run -d -p 34938:8080 --name xxxx -e WEBSITE_SITE_NAME=xxxx -e WEBSITE_AUTH_ENABLED=False -e WEBSITE_ROLE_INSTANCE_ID=0 -e WEBSITE_HOSTNAME=xxxx -e WEBSITE_INSTANCE_ID=e9d7d581f74fa3aa82fed4e52ba7b581a49d7a218f02ccc2fb509536bfb3742f -e HTTP_LOGGING_ENABLED=1 appsvc/dotnetcore:2.2_1905171704

微软文档表明这对于 Linux 来说还不可能。 https://learn.microsoft.com/en-us/azure/app-service/troubleshoot-diagnostic-logs
此外，Twitter 上的@AzureSupport 也证实了这一点 https://twitter.com/AveerRa/status/1174683871134330881
关于Linux 上的 Azure 应用服务不显示 Web 服务器日志，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57611651/
