azure - 如何使用 Postman 将文件上传到 Azure Blob 存储？

Question

我正在尝试将 base64 字符串作为图像文件上传到 Azure Blob 存储。使用https://learn.microsoft.com/en-us/rest/api/storageservices/put-blob文档尝试创建 blob。

Request Syntax:  
PUT https://myaccount.blob.core.windows.net/mycontainer/myblockblob HTTP/1.1  
  
Request Headers:  
x-ms-version: 2015-02-21  
x-ms-date: <date>  
Content-Type: text/plain; charset=UTF-8  
x-ms-blob-content-disposition: attachment; filename="fname.ext"  
x-ms-blob-type: BlockBlob  
x-ms-meta-m1: v1  
x-ms-meta-m2: v2  
Authorization: SharedKey myaccount:YhuFJjN4fAR8/AmBrqBz7MG2uFinQ4rkh4dscbj598g=  
Content-Length: 11  
  
Request Body:  
hello world 

我收到如下回复，

<?xml

<Error>
    <Code>AuthenticationFailed</Code>
    <Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

如何解决这个问题？

Answer 1

上传 blob 的一种简单方法是使用 sas token 。

导航到 Azure 门户 -> 您的存储帐户 -> 共享访问签名，然后选择屏幕截图中的以下选项 -> 然后单击生成 SAS 和连接字符串 按钮。截图如下:

然后复制 SAS token ，并将其附加到 URL。那么新的网址如下所示:https://myaccount.blob.core.windows.net/mycontainer/myblockblob?sv=2019-12-12&ss=b&srt=coxxxx

接下来，在 postman 中粘贴新网址。在 header 中，您可以删除 Authorization 字段。

测试结果如下:
