Question

我的webjob从我的blob存储中删除文档。如果我将代码复制到控制台应用程序并运行它，它将运行完成而不会出现错误。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选择Add - ＆gt; New Azure Webjob项目），将代码复制到Functions.cs并部署，Azure在运行webjob时抛出异常：

import graphene
from django.db import connection
from collections import namedtuple


class OrderItemType(graphene.ObjectType):
    date = graphene.core.types.custom_scalars.DateTime()
    order_id = graphene.ID()
    uuid = graphene.String()

class QueryType(graphene.ObjectType):
    class Meta:
        type_name = 'Query' # This will be name in graphene 1.0

    order_items = graphene.List(OrderItemType)

    def resolve_order_items(root, args, info):
        return get_order_items()    


def get_db_rows(sql, args=None):
    cursor = connection.cursor()
    cursor.execute(sql, args)
    columns = [col[0] for col in cursor.description]
    RowType = namedtuple('Row', columns)
    data = [
        RowType(*row) # Edited by John suggestion fix
        for row in cursor.fetchall() ]

    cursor.close()
    return data

def get_order_items():
    return get_db_rows("""
        SELECT j.created_dt AS date, j.order_id, j.uuid
        FROM job AS j
        LIMIT 3;
    """)

我没有队列，所以这可能是错误来自哪里，但奇怪的是我不会尝试访问队列，我只访问我的blob存储。

不确定这是否有帮助，但我的webjobs Program.cs看起来像这样：

=======================================================

这是作业中唯一使用存储的代码，其余的是获取列表的数据库内容等。

    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();
    }

编辑：我还应该补充一点，这只是在更新后才开始：

Microsoft.Azure.WebJobs从1.1.1到1.1.2
Microsoft.Azure.WebJobs.Core 1.1.1至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），但是我没有使用访问blob的方式更改代码。

更新 - 我的webjob在周末跑完了。它在22:23失败并出现与上述相同的错误，但在22:24重试时成功运行。但是今天再次以同样的错误再次失败。我将尝试删除@FleminAdambukulam所述的日志记录，但奇怪的是如何在没有任何代码更改的情况下运行，但之后再次失败......

问题是存储帐户属于仅支持Blob的特殊类型。即使您没有使用队列，WebJobs SDK也会在内部依赖它们。因此，要使用WebJobs SDK，您需要使用常规存储帐户。

在控制台中运行webjob但在Azure上引发异常：无法解析远程名称：＆＃39; xxx.queue.core.windows.net＆＃39;
