django - 使用 boto 进行 S3 上传我收到 EOF 错误

Question

我正在尝试将文件上传到 S3(实际上上传有效)，但我的应用程序崩溃并抛出以下错误:
fp is at EOF. Use rewind option or seek() to data start.
我看到人们解决问题的一些方法是添加 rewind=True到他们的 set_contents_from_string 调用。但是，这会引发以下错误:
set_contents_from_string() got an unexpected keyword argument 'rewind'
以下是我views.py的内容.我究竟做错了什么？

def store_in_s3(filename, filecontent):
    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 = filename
    k.set_metadata("Content-Type", mime)
    k.set_contents_from_string(filecontent)
    #k.set_contents_from_string(filecontent, rewind=True)
    k.set_acl("public-read")

def add_m(request, points=None):
    mname = request.GET.get ('mname')
    format = request.GET.get ('format')
    type = request.GET.get ('type')
    if request.method == "POST":
        formtoaddm = spiceform(request.POST, request.FILES)
        if formtoaddm.is_valid():
            new_m = formtoaddm.save(commit=False)
            new_m.adder = request.user
            mname = new_m.mname
            file = request.FILES['content']
            filename = file.name
            filecontent = file.read()
            store_in_s3(filename, filecontent)
            ...

Answer 1

后

filecontent = file.read()

放:

file.seek(0)
