我想用Dropzone.js文件用烧瓶。上传文件后，我想保存文件，并显示在另一个页面上传的文件名（重定向后）。但在浏览器中，我收到的文件名等于“sample\u value”。如何解决这个问题？你知道吗

Python

import os
from flask import Flask, render_template, request,redirect, url_for

app = Flask(__name__)
app.config['UPLOADED_PATH'] = os.getcwd() + '/upload'

@app.route('/')
def index():
    # render upload page
    return render_template('index.html')


@app.route('/upload', methods=['GET', 'POST'])
def upload():
    n='sample_value'
    if request.method == 'POST':
        for f in request.files.getlist('file'):
            n=f.filename
            f.save(os.path.join(app.config['UPLOADED_PATH'], f.filename))
            print(f.filename)
            # There i get real file name
            n=f.filename
    return redirect(url_for('found', file_name=n), code=307)

@app.route('/found',methods=['GET', 'POST'])
def found():
        #There my file name is "sample_value"
    print('File name after redirect ', request.args.get('file_name'))
    return request.args.get('file_name')

if __name__ == '__main__':
    app.run(host='0.0.0.0', port =5000, debug=True, threaded=True)

模板

<html>
<body>
<script src="{{ url_for('static', filename='js/dropzone.js') }}"></script>
<script src="{{ url_for('static', filename='js/jquery.js') }}"></script>
<form action="{{ url_for('upload') }}" class="dropzone" id="my-dropzone" method="POST" enctype="multipart/form-data">
</form>
<script>
Dropzone.autoDiscover = false;

$(function() {
  var myDropzone = new Dropzone("#my-dropzone");
  myDropzone.on("queuecomplete", function(file) {
    // Called when all files in the queue finish uploading.
  window.location = "{{ url_for('upload') }}";
  });
})
</script>
</body>
</html>

在处理请求之前如何理解重定向执行？你知道吗

我假设您没有在Dropzone中指定方法，那么它默认使用GET方法。检查Dropzone documentation并将方法指定为POST。你知道吗

n="sample_value"
if request.method == 'POST': # This is always false.
    ...

>>> print(n) # n has never been replaced
sample_value
