Azure 应用服务日志流 - 不定 'Welcome, you are now connected to log-streaming service'

Question

是否有人遇到过 Azure 中的日志流问题，其中出现消息“欢迎，您现在已连接到日志流服务”。是否只是持续每秒发送 10 次垃圾邮件？我现在无法查看我的日志。

根据我的经验，当应用程序在启动阶段挂起时，就会发生这种情况。下面是有关我如何解决此问题的一些信息。

我也遇到了同样的问题。事实上，我不仅在日志流 View 中遇到这个问题，而且当我运行az webapp log tail时也遇到这个问题。我收到与 azure-cli 相关的 Python 错误，其中 urllib3.exceptions.ProtocolError: ("Connection broken: InvalidChunkLength就在其中。

我调试它:

• 将我的 NodeJS 应用程序剥离为“Hello, World”快捷应用程序。
• 正在部署
• 日志流像问题中那样循环
• 调用测试端点直到收到响应
• 现在日志流会记录一些有用的内容

为了完整起见，这篇文章描述了一种通过更改日志记录设置来尝试修复它的方法:https://learn.microsoft.com/en-us/answers/questions/918228/app-service-log-stream-prints-the-welcome-message.html

我在这篇文章中尝试的具体步骤:

• 重新启动应用
• 在监控 > 应用服务日志下，禁用日志并将保留设置为 0 并返回
• 再次重新启动应用
• 重复最后两个步骤几次

没有效果。我希望这些步骤可以对某些人有所帮助，因为应用程序需要足够的时间才能摆脱预热阶段。

在不同的应用程序名称/资源组下进行部署对我来说也没有帮助，在我看来，这表明问题在于代码，而不是环境。
