azure - 通过 Web API 将文件上传到 azure 文件存储

Question

我尝试将文件上传到 Azure 的云存储，但只收到错误请求 400 响应。在本地主机上运行应用程序并尝试连接到我们在 Azure 上的帐户。

当我将其放入 try/catch 中时，我在最后一行收到错误请求 400

cloudFile.Create(fileSize);

下面的这一行返回 null，但当我在 if 语句中检查文件共享时它存在:

var listShares = fileClient.ListShares(); // null

我只找到了一个关于如何实际上传这样的文件的示例:

// Connect to Azure Storage         
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
        CloudConfigurationManager.GetSetting("AzureStorageConnectionString"));

    //Create a CloudFileClient object for credentialed access to File storage.
    CloudFileClient fileClient = storageAccount.CreateCloudFileClient();

    //Get a reference to the file share we created previously.
    CloudFileShare share = fileClient.GetShareReference("appbackup");

    var listShares = fileClient.ListShares();

    //Ensure that the share exists.
    if (share.Exists())
    {
        //Get a reference to the root directory for the share.
        CloudFileDirectory rootDir = share.GetRootDirectoryReference();

        //Get a reference to the sampledir directory we created previously.
        CloudFileDirectory sampleDir = rootDir.GetDirectoryReference("sampledir");

        //Ensure that the directory exists.
        if (sampleDir.Exists())
        {
            var test = rootDir.ListFilesAndDirectories();
            var Credentials = new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials("accountName", "keyValue");

            string stringUri = storageAccount.FileStorageUri.PrimaryUri + share.Name + "/sampledir/";

            Uri theUri = new Uri(stringUri);
            CloudFile cloudFile = new CloudFile(theUri, Credentials);
            System.IO.FileInfo fi = new System.IO.FileInfo(filepath);
            long fileSize = fi.Length;
            cloudFile.Create(fileSize);
        }
    }

我认为您的代码存在问题:

string stringUri = storageAccount.FileStorageUri.PrimaryUri + share.Name + "/sampledir/";

您没有将文件名添加到 stringUri 中。请尝试将文件名添加到 stringUri 中，这样应该可以解决问题。
