寶途上傳到S3不工作的某些文件類型

下面的代碼保存上傳的文件在S3：寶途上傳到S3不工作的某些文件類型

def store_in_s3(filename, filecontent, type, modelname, format, manufacturer, adder_id): 
    extension = os.path.splitext(filename)[1] 
    filename = modelname + "-" + manufacturer + "-" + type + "-" + format + "-" + str(adder_id) + extension 
    pathtofile = "Parts/%s" % (filename) 
    conn = S3Connection(settings.AWS_ACCESS_KEY_ID, settings.AWS_SECRET_ACCESS_KEY) 
    b = conn.create_bucket('mybucket') 
    mime = mimetypes.guess_type(filename)[0] 
    k = Key(b) 
    k.key = "/media/Parts/%s" % (filename) 
    k.set_metadata("Content-Type", mime) 
    k.set_contents_from_string(filecontent) 
    k.set_acl("public-read") 
    return pathtofile

它的工作原理FIE的圖像和文本文件，但是當我嘗試上傳特定類型的文件，我得到這個回來不知道爲什麼：

<Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided.

您使用的是什麼版本的boto？ – garnaat

Boto Version 2.6 – user1328021

boto和S3都不關心文件類型或文件內容。所以，我懷疑這個問題與上傳的密鑰的名稱或與之相關的元數據有某種關係。是否有可能看到請求的完整調試日誌？這可能有助於確定問題。 – garnaat

在你的代碼：

k.set_metadata("Content-Type", mime)

啞劇必須是無，它看起來像S3不允許文件的Content-Type是無。您可以將其刪除，該文件將被設置爲s3中的默認內容類型。

當使用

mimetypes.guess_type(filename)

文件名應與文件擴展名，例如，end，www.test.com/1.jpg?code=XXXX
MIME類型無法猜測的類型，將返回沒有。
