Question

我在内部服务器上运行webjob（即不在Azure上托管）。它可以很好地从队列中获取作业，并且可以毫无问题地处理它们，但是当它完成处理队列中的作业时我得到以下异常：

webjob在我的开发机器上运行正常，在另一台PC上运行但在Windows 2012 R2服务器上获得异常。如果我更改连接字符串以从另一个Azure帐户中的队列中读取它可以正常工作，所以我猜我的主Azure帐户上的设置有问题，但我不明白为什么它运行时不是问题在其他机器上。

我目前正在使用Microsoft.Azure.WebJobs的v1.1.0和WindowsAzure.Storage的v7.0.0。我使用WindowsAzure.Storage的v5.0.2版本的Microsoft.Azure.WebJobs v1.1.1得到了相同的结果。

我已按照问题Azure Web Job-The remote server returned 404中的建议进行操作，并确认我已设置了这4个blob容器。

修改我将microsoft.azure.webjobs nuget包更新到1.1.2，这似乎解决了上述问题，但在愉快地运行了2周后，错误突然重新出现。没有代码更改或重新部署;工作正常的代码无缘无故停止工作，据我所知，我们的Azure帐户没有变化。我已将配置文件更改为指向不同的Azure帐户，并且它再次正常工作。

有关导致404的原因的任何建议？

Answer 1

未处理的异常：Microsoft.WindowsAzure.Storage.StorageException

这意味着您尚未正确配置存储空间。 Web作业需要在app.config AzureWebJobsDashboard ， AzureWebJobsStorage 中设置两个appSettings。

<add name="AzureWebJobsDashboard" connectionString="DefaultEndpointsProtocol=https;AccountName=ACCOUNTNAME;AccountKey=ACCOUNTKEY" />
<add name="AzureWebJobsStorage" connectionString="DefaultEndpointsProtocol=https;AccountName=ACCOUNTNAME;AccountKey=ACCOUNTKEY" />

此外，这些设置可能指向相同的blob存储，Web作业将创建所需的文件夹并写入它们。

Webjob正在将日志和其他一些东西写入blob存储，这就是它失败的原因，因为它试图写入数据，但无法访问存储

Answer 2

我已将Microsoft.Azure.WebJobs nuget软件包更新到新的1.1.2版本，现在看起来工作正常。

修改查看更新的问题。这个答案不再有效
