python、flask上传图片方法无法完成

Question

I am trying to code an upload image page in python flask web application.我正在尝试在 python flask web 应用程序中编写上传图像页面。 Here is upload.html:这里上传.html：

<body>
    <h1>file uploader</h1>
    <form id="upload-form" action="{{ url_for('upload') }}" method="POST" enctype="multipart/form-data"></form>
    <input type="file" name="file" accept="image\\*" multiple>
    <input type="submit" value="send">
</body>

and here is my upload method in application.py这是我在 application.py 中的上传方法

@app.route("/upload", methods=['GET','POST'])
def upload():
    target = os.path.join(APP_ROOT, 'images\\')
    if not os.path.isdir(target):
        os.mkdir(target)
    for file in request.files.getlist("file"):
        fileName = file.file_name
        destination = "\\".join([target,fileName])
        print(destination)
        file.save(destination)

return render_template('upload.html')

I call upload method from home.html as我从 home.html 调用上传方法为

<a class="nav-link" href="{{ url_for('upload') }}">upload</a>

This code creates the images folder but does not add the image to the folder.此代码创建图像文件夹，但不将图像添加到文件夹。 It cannot goes into 'for file in request.files.getlist("file"):' loop.它不能进入'for file in request.files.getlist("file"):' 循环。 I cannot recognize what causes to this problem?我无法识别导致此问题的原因是什么？

<form id="upload-form" action="{{ url_for('upload') }}" method="POST" enctype="multipart/form-data"></form>
<input type="file" name="file" accept="image\\*" multiple>

to至

<form id="upload-form" action="{{ url_for('upload') }}" method="POST" enctype="multipart/form-data">
    <input type="file" name="file" accept="image\\*" multiple>
    <input type="submit" value="send">
</form>

and change和改变

fileName = file.file_name

to至

fileName = file.filename

my problem solved successfully.我的问题成功解决了。 Thank you @waynetech so much:).非常感谢@waynetech :)。
