[英]Python Error: AttributeError: 'builtin_function_or_method' object has no attribute
[英]Python error: builtin function or method object has no attribute 'StringIO'
我只是想下載一張圖片。 然后將其上傳到Amazon S3。 但它不起作用。
'builtin_function_or_method' object has no attribute 'StringIO'
Traceback (most recent call last):

我下載並上傳的代碼是這樣的:
tdata = tools.download("http://farm5.static.flickr.com/4148/5124630813_c11b05e6da_z.jpg")
imgpath = s3.upload_thumbnail(thumbnail_name=tools.randomString(10), thumbnail_data=tdata,bucket="fabletest")
print imgpath
我正在使用的庫是s3庫。 我在某個地方下載了它,所以它應該是標准的。

有人可以幫我上傳這張圖片到S3嗎?
在你的代碼中:
return self.bucket.connection.make_request('PUT', self.bucket.name,......
AttributeError: 'str' object has no attribute 'connection'
這意味着一些如何將self.bucket計算為字符串,並且您顯然無法在其上調用方法“連接”。
因此,為了進一步分析,請查看函數upload_thumbnail,它期望bucket = cache_bucket()作為參數。 那就是它需要一個桶對象。
def upload_thumbnail(thumbnail_name,thumbnail_data=None,thumbnail_path=None,bucket=cache_bucket
(),conn=_conn(),notes=None,image_id=None)
你在代碼中傳遞的是字符串!! - >(bucket =“fabletest”)
imgpath = s3.upload_thumbnail(thumbnail_name=tools.randomString(10), thumbnail_data=tdata,bucket="fabletest")
你的代碼應該是這樣的。 你可能需要消毒這個。 但關鍵是將桶和連接對象傳遞給函數upload_thumbnail函數。
import S3
connection = S3.AWSAuthConnection('your access key', 'your secret key')
buck = connection.create_bucket('mybucketname')
tdata = tools.download("http://farm5.static.flickr.com/4148/5124630813_c11b05e6da_z.jpg")
imgpath = s3.upload_thumbnail(thumbnail_name=tools.randomString(10), thumbnail_data=tdata,bucket=buck, conn=connection)
print imgpath
