我與博託第一次測試失敗，SignatureDoesNotMatch

因此，這裏是我的S3桶第一次測試使用博託：我與博託第一次測試失敗，SignatureDoesNotMatch

import boto 

user_name, access_key, secret_key = "testing-user", "xxxxxxxxxxxxx", "xxxxxxxx/xxxxxxxxxxxx/xxxxxxxxxx(xxxxx)" 
conn = boto.connect_s3(access_key, secret_key) 
buckets = conn.get_all_buckets()

我收到以下錯誤：

Traceback (most recent call last): 
    File "test-s3.py", line 9, in <module> 
    buckets = conn.get_all_buckets() 
    File "xxxxxx/lib/python2.7/site-packages/boto/s3/connection.py", line 440, in get_all_buckets 
    response.status, response.reason, body)

我應該怎麼解決這個問題？

Boto版本是2.38.0

仔細檢查您的訪問密鑰和密鑰以驗證它們是否正確。另外，請檢查客戶端計算機上的時間，並確保它是正確的。 – garnaat

好的，我剛纔注意到提供一個錯誤的密碼導致了相同的錯誤信息......我認爲認證很好，因爲在boto.connect_s3成功執行後引發了錯誤。我明白，也許涉及懶惰的操作... –

直到實際進行調用後纔會檢查憑據。 – garnaat
