Flask - Upload file

要上传文件，form必须要加enctype=multipart/form-data属性。

 

from flask_wtf.file import FileField

class MyForm(FlaskForm):
    image = FileField('Upload Image:')

 

from werkzeug.utils import secure_filename
import os

    my_form = MyForm()
    if request.method == 'POST':
        if my_form.validate_on_submit():
            f = my_form.image.data
            filename = secure_filename(f.filename)
            f.save(os.path.join(current_app.instance_path, 'uploaded_files', filename))

 

uploaded_files目录需要存在，否则会报错。
