azure-webjobs - Azure Web Job - 远程服务器返回 404

Question

我有一个连续运行的 Web 作业，它监听一个 start 队列和一个停止 queue 及其各自的功能。 Web 作业中有 3 个预定义进程，start 队列包含一条消息，其中提到要启动的进程名称，而 stop 队列包含一条消息，其中提到进程名称停止。

自从过去 4 周以来，每当 webjob 停止进程时，它就会崩溃并重新启动并出现上述异常。

Executing: 'Functions.StartProcess' because New queue message detected on 'start'.

Executing: 'Functions.StopProcess' because New queue message detected on 'stop'.

Disposed Process A
Updated the status of Process A to 3

webjob 甚至不包含任何删除 blob 文件的代码。

调试时，调试器在抛出异常时没有指向任何特定行，因此我不知道真正的原因是什么。

PS :它以前运行完美，每个函数的主体都包含在 try catch block 中。 catch block 不会重新抛出异常，而只是记录堆栈跟踪并继续。

编辑

我必须检查下面的容器是否在那里

在 webjob 的存储中，还更新了 Microsoft.Web.WebJobs.Publish nuget 包。 我真的不确定这是否能解决问题。

看起来您是对的，您确实需要手动创建 blob 容器，或发布网络作业，在这种情况下，它看起来像环境将为您创建容器。

当我最初尝试时，我先进行了发布，而且效果非常好。第二个项目，我做的不同，所以我先运行控制台应用程序，它一直失败并显示 404。

因此，您需要创建:

• azure-webjobs-仪表板
• azure-webjobs-hosts
• azure-jobs-hosts-archive
• azure-jobs-hosts-output

希望对大家有帮助。
