通过 flask 和 wtforms MultipleFileField 保存多个文件

Saving multiple files through flask and wtforms MultipleFileField

我正在尝试使用 MultipleFileField 从 Flask 中的请求获取并保存多个文件。但问题是我无法遍历它。我的意思是:
表格 class

class TestForm(FlaskForm):
    user_id = IntegerField('user_id', validators=[DataRequired()])
    name = StringField('name', validators=[DataRequired()])
    description = StringField('description', validators=[DataRequired()])
    category_id = IntegerField('category_id', validators=[DataRequired()])
    date_of_purchase = DateField('date_of_purchase', validators=[DataRequired()])
    guarantee_period = IntegerField('guarantee_period', validators=[DataRequired()])
    files = MultipleFileField('files')

并查看代码:

form = TestForm()
...
files = form.files
for file in files:
   with open(path.join('some_path', file.filename), 'wb') as f:
        f.write(file.read())

我收到了这么大的请求:

["<_io.BufferedReader name='1.jpg'>", "<_io.BufferedReader name='2.jpg'>"]

但我收到错误消息:

AttributeError: 'str' object has no attribute 'filename'

因此它将 io.BufferedReader 转换为 str。我该怎么做才能解决这个问题?

您的 'file' 是一个字符串,在 with 语句之前将其切片并保存到文件名变量中,然后仅在 with 语句中包含 'filename' 。类似于:

form = TestForm()
...
files = form.files.data
for file in files:
   with open(path.join('some_path', file), 'wb') as f:
        f.write(file.read())
