WindowsAzure.Storage V2 StorageException

问题描述

我是从WindowsAzure.StorageClient 1.7迁移到WindowsAzure.Storage 2.0，和我的工作，现在在例外的管理。在此之后的guide和其他来源，我发现我不得不从

I'm migrating from WindowsAzure.StorageClient 1.7 to WindowsAzure.Storage 2.0, and I'm working right now on the management of the exceptions. Following this guide and other sources, I found out I had to migrate from

try
{
    // Something
}
catch (StorageClientException e)
{
    switch (e.ErrorCode)
    {
        case StorageErrorCode.ContainerNotFound:
        case StorageErrorCode.ResourceNotFound:
        case StorageErrorCode.BlobNotFound:
        case StorageErrorCode.ConditionFailed:
            // Do something
    }
}

到

try
{
    // Something
}
catch (StorageException e)
{
    switch (e.RequestInformation.ExtendedErrorInformation.ErrorCode)
    {
        case StorageErrorCodeStrings.ContainerNotFound:
        case StorageErrorCodeStrings.ResourceNotFound:
        case BlobErrorCodeStrings.BlobNotFound:
        case StorageErrorCodeStrings.ConditionNotMet:
            // Do something
    }
}

看起来很简单。现在的问题是ExtendedErrorInformation总是等于空。该HttpStatusMessage，而不是说'指定的一滴不存在。，因为它应该。

Looks simple.The problem is ExtendedErrorInformation is always equal to null. The HttpStatusMessage instead says 'The specified blob does not exist.', as it should.

我以为是在测试环境模拟器造成的，而是试图在一个真正的Azure环境掘进我同样的情况。

I thought it was caused by the simulator of the test environment, but trying it in a real Azure environment drived me to the same situation.

你知道吗？

推荐答案

另一种方法是看 RequestInformation.HttpStatus code 代替。这似乎是更可靠反正。您的code转换而容易：

Another option is to look at the RequestInformation.HttpStatusCode instead. This seems to be more reliable anyway. Your code translates rather easily to:

try
{
    // Something
}
catch (StorageException e)
{
    switch (e.RequestInformation.HttpStatusCode)
    {
        case (int)HttpStatusCode.NotFound:
        case (int)HttpStatusCode.PreconditionFailed:
        // Do something
    }
}
