I was finally able to successfully upload something however when I checked it in the S3 console all that was uploaded was HTML: ＆LT;输入ID =形象NAME =图像类型=文件＆GT;瓶：def s3upload(image, acl='public-read'): key = app.config['S3_KEY'] secret = app.config['S3_SECRET'] bucket = app.config['S3_BUCKET'] conn = S3Connection(key, secret) mybucket = conn.get_bucket(bucket) r = redis.StrictRedis(connection_pool = pool) iid = r.incr('image') now = time.time() r.zadd('image:created_on', now, iid) k = Key(mybucket) k.key = iid k.set_contents_from_string(image) return [email protected]('/', methods = ['GET', 'POST'])def index(): form = ImageForm(request.form) print 'CHECKING REQUEST' if form.validate_on_submit(): print 'VALID REQUEST' image = form.image.data s3upload(image) else: image = None r = redis.StrictRedis(connection_pool = pool) last_ten = r.zrange('image:created_on', 0, 9) print last_ten images = [] key = app.config['S3_KEY'] secret = app.config['S3_SECRET'] bucket = app.config['S3_BUCKET'] conn = S3Connection(key, secret) mybucket = conn.get_bucket(bucket) for image in last_ten: images.append(mybucket.get_key(image, validate = False)) return render_template('index.html', form=form, images=images)我是previously告知，使用 set_contents_from_file 是不正确的，而是使用 set_contents_from_stringI was previously told that using set_contents_from_file was incorrect and instead to use set_contents_from_string Flask AttributeError的：UNI code'对象有没有属性'告诉'不过，我觉得这可能是问题。感谢您的帮助。However I feel like this may be the issue. Thanks for your help.推荐答案只有HTML上传成功，因为你使用 set_contents_from_string 方法，该方法仅适用于基于文本的文件和作品不是图片，因为他们不被视为字符串。您应该使用 set_contents_from_file 方法的在文档中提到这里。Only HTML uploads were successful because you are using set_contents_from_string method which works only for text based files and not images since they are not treated as string. You should use set_contents_from_file method as mentioned in the docs here.检索文件对象为 request.files ['形象'] ，并把它传递给了 set_contents_from_file 方法Retrieve the file object as request.files['image'] and pass it on to the set_contents_from_file method.def s3upload(image, acl='public-read'): # do things before k.set_contents_from_file(image) # do more [email protected]('/', methods = ['GET', 'POST'])def index(): form = ImageForm(request.form) if form.validate_on_submit(): s3upload(request.files['image']) # do rest of stuff 这篇关于瓶图片上传到S3只发送HTML的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
