Azure Blob PUT Rest api - 收到错误“签名字段格式不正确”

Question

我尝试使用 Python 请求模块将新的 blob 上传到 Azure 存储计数器，但收到错误签名字段格式不正确。有人可以帮我理解我在这里缺少什么吗？

import requests

file_name = "test.txt"

account = "<account_name>"
container = "<container_name>"
blob = "<blob_name>"
key = "sp=rwdlacupiytfx&st=2023-07-10T15:59:34Z&se=2023-12-10T23:59:34Z&spr=https&sv=2022-11-02&sr=c&sig=<sig>"

file = open(file_name, "rb")

url = f"https://{account}.blob.core.windows.net/{container}/{blob}/{file_name}?{key}"
print(url)
headers = {'x-ms-version': '2020-10-02', 'x-ms-blob-type': 'BlockBlob'}

test_response = requests.put(url, data = file, headers = headers)

if test_response.ok:

    print("Upload completed successfully!")
    print(test_response.text)

else:
    print("Something went wrong!")
    print(test_response.text)

错误：

<?xml version="1.0" encoding="utf-8"?><Error><Code>AuthenticationFailed</Code><Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

我从 Azure Blob Storage Explorer 中的属性面板获取了 SAS：

错误 “签名字段格式不正确” 表示您在 URL 中使用的共享访问签名 (SAS) 令牌的格式存在问题。

我尝试使用以下代码并能够将 blob 上传到存储。

代码：

import requests

file_name = "path/to/file.txt"

account = "<storage_name>"
container = "<container_name>"
blob = "test3465.txt"
sas_token = "<SAS_token>"  # Replace Your SAS token (excluding "?")

url = f"https://{account}.blob.core.windows.net/{container}/{blob}/{file_name}?{sas_token}"
print(url)

headers = {'x-ms-version': '2020-10-02', 'x-ms-blob-type': 'BlockBlob'}

with open(file_name, "rb") as file:
    test_response = requests.put(url, data=file, headers=headers)

if test_response.ok:
    print("Upload completed successfully!")
    print(test_response.text)
else:
    print("Something went wrong!")
    print(test_response.text)

输出：

 https://venkat678.blob.core.windows.net/test/test3465.txt/./test3465.txt?sv=2022-11-02&ss=bfqt&srt=co&sp=rwdlacupiytfx&se=2023-09-12T23:00:16Z&st=2023-09-12T15:00:16Z&spr=https&sig=xxxxxxxx
