运行 控制台中的 webjob 工作但在 Azure 上抛出异常：无法解析远程名称：'xxx.queue.core.windows.net'
Running webjob in console works but throws exception on Azure: The remote name could not be resolved: 'xxx.queue.core.windows.net'
我的网络作业从我的 blob 存储中删除了文档。如果我将代码复制到控制台应用程序并 运行 它，它将 运行 无误地完成。如果我在 visual studio 中创建一个新的 webjob（右键单击我的网站项目并 select 添加 -> 新建 Azure Webjob 项目），将代码复制到 Functions.cs 并部署，Azure 会抛出异常当 运行 网络作业时：

=======================================================
我没有队列，所以这可能是错误的来源，但奇怪的是我没有尝试访问队列，我只是访问我的 blob 存储。
不确定这是否有帮助，但我的网络作业 Program.cs 看起来像这样：
static void Main()
{
JobHostConfiguration config = new JobHostConfiguration();
config.Tracing.ConsoleLevel = TraceLevel.Verbose;
config.UseTimers();
var host = new JobHost(config);
// The following code ensures that the WebJob will be running continuously
host.RunAndBlock();
}
这是作业中唯一使用存储的代码，其余的是用于获取列表等的数据库内容。
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString"));
// Create the blob client.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference("agentdocuments");
foreach (var doc in expiredDocs)
{
if (doc.ContentLength == 1)
{
// Retrieve reference to blob
CloudBlockBlob blockBlob = container.GetBlockBlobReference($"{doc.SubDomain.ToLower()}/{doc.ClientId}/{doc.FileId}");
await blockBlob.DeleteIfExistsAsync();
}
}
编辑：我还应该补充一点，这只是在更新后才开始发生：
- Microsoft.Azure.WebJobs 从 1.1.1 到 1.1.2
- Microsoft.Azure.WebJobs.核心从 1.1.1 到 1.1.2
- WindowsAzure.Storage 从 5.0.2 到 7.2.0 和
还有一些代码更改和其他更新（如 Newtonsoft.Json、Microsoft.WindowsAzure.ConfigurationManager、Microsoft.Web.WebJobs.Publish），但我访问 blob 的方式没有代码更改。
更新 - 我的网络作业 运行 在周末完成。它在 22:23 失败并出现与上述相同的错误，但随后 运行 在 22:24 重试时成功。但是今天又因为同样的错误再次失败。我将按照@FleminAdambukulam 的说明尝试删除日志记录，但 st运行ge 如何在没有任何代码更改的情况下 运行 但随后再次失败......
问题是存储帐户是只支持 Blob 的特殊类型。即使您没有使用队列，WebJobs SDK 在内部也依赖于它们。因此，为了使用 WebJobs SDK，您需要使用常规存储帐户。
