Azure存储表UpdateObject - 其中一个请求输入无效

Question

任何帮助，非常感谢。

我正在使用Azure存储表的1.6 SDK。在UpdateObject（）我收到以下错误：

<?xml version="1.0" encoding="utf-8" standalone="yes"?> 
<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"> 
    <code>InvalidInput</code> 
    <message xml:lang="en-US">One of the request inputs is not valid. 
RequestId:b78bc343-f93c-4ec7-8991-24386131de43 
Time:2012-08-08T01:25:32.4366914Z</message> 
</error> 

这里的请求（从小提琴手拉）：

    </m:properties> 
    </content> 
</entry> 

这里的调用UpdateObject（）：

Public Sub Update(existingItem As UserDataModel) 
    _ServiceContext.AttachTo(UserDataServiceContext.UserTableName, existingItem, "*") 
    _ServiceContext.UpdateObject(existingItem) 
    _ServiceContext.SaveChanges() 
End Sub 

以下是初始化服务上下文的代码：

Public Sub New() 
    Try 
     Dim storageAccount = CloudStorageAccount.FromConfigurationSetting("DataConnectionString") 
     _ServiceContext = New UserDataServiceContext(storageAccount.TableEndpoint.ToString(), storageAccount.Credentials) 
     _ServiceContext.IgnoreResourceNotFoundException = True 
     ' Create the tables 
     ' In this case, just a single table. 
     storageAccount.CreateCloudTableClient().CreateTableIfNotExist(UserDataServiceContext.UserTableName) 
    Catch ex As Exception 
     Debug.WriteLine("Problem with New() UserDataSource. Error: " & ex.Message) 
    End Try 
End Sub 

个

让我知道如果有什么我可以提供...

干杯，

托马斯

Answer 1

该URL看起来不对，但我不确定它是如何得到这种方式的......它通常应该是类似于https://<account>.table.core.windows.net/<table>(PartitionKey='<pkey>',RowKey='<rkey>')。但我没有解释你为什么看起来不正确。 （代码看起来相当简单。）

是否可以执行其他操作，如插入？当你这样做的时候，这些网址在Fiddler中看起来是否正确？
