我正在使用 Azure 存储客户端库连接到我的 Azure Blob 存储并发布一些文件。以下代码是我用来建立连接和创建 blob 容器的代码的摘录:

var storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("settingsName"));

client = storageAccount.CreateCloudBlobClient();

var container = client.GetContainerReference("containerName");
container.CreateIfNotExists();

这在我的本地计算机上运行良好。但是,如果我尝试在不同的服务器上运行完全相同的代码,则会出现以下异常:

Microsoft.WindowsAzure.Storage.StorageException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

有人知道是什么原因造成的吗?我已经在谷歌上搜索这个问题好几天了,没有任何解决方案。

最佳答案

这个线程已经休眠了一段时间,但我最近遇到了同样的问题;我想分享我的成果,希望其他人将来可以从中受益。

在尝试从服务器写入 Azure 存储 blob 时,我们收到了相同的错误,尽管相同的代码在本地和其他服务器上运行良好:

Microsoft.WindowsAzure.Storage.StorageException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

首先,我们验证计算机上是否安装了正确的证书颁发机构。通常,这可能是罪魁祸首。但是,就我们而言,我们拥有所有必要的证书颁发机构。

最终的问题是服务器无法解析存储帐户的正确 IP 地址 (yourstorageaccountname.blob.core.windows.net)。

在本地,尝试从命令提示符 ping 您的存储帐户,如下所示:

ping yourstorageaccountname.blob.core.windows.net

您应该看到来自本地计算机的 ping 能够解析您的 Blob 帐户的 IP 地址(13.88.144.248 等)。

现在尝试从您的服务器 ping blob 帐户,您将在其中收到此异常。如果 ping 无法解析 IP 地址,或者解析错误的 IP 地址(如我的情况),您可能已经发现了问题。

如果是这种情况,向 C:\Windows\System32\drivers\etc\hosts 文件添加一个简单的映射可以解决我们的问题。如果您遇到同样的问题,向该文件添加 IP 映射应该可以解决问题。该映射应将本地 ping 中的 IP 映射到 blob 帐户的主机名。这是一个例子:

13.88.144.248 yourstorageaccountname.blob.core.windows.net

请注意,您必须以管理员身份运行文本编辑器(记事本等)才能正确保存主机文件。
