如何在flask中设置所见即所得编辑器insertImage的默认目录

app.config['INSERT_IMAGE_DEFAULT_DIR'] = '/path/to/default/directory'

from flask import request

@app.route('/upload_image', methods=['POST'])
def upload_image():
    image_file = request.files['image']
    if image_file:
        image_file.save(app.config['INSERT_IMAGE_DEFAULT_DIR'] + '/' + image_file.filename)
        # 返回图片的URL或其他相关信息
        return 'Image uploaded successfully'
    else:
        return 'No image file provided'
