如何设置应用路径来获取上传到flask上的图片？

from flask import Flask, request, url_for
import os

app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = 'uploads'

@app.route('/upload', methods=['POST'])
def upload():
    file = request.files['image']  # 获取上传的图片文件
    if file:
        filename = file.filename
        file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))  # 保存图片到指定路径
        return '上传成功！'
    return '上传失败！'

@app.route('/image/<filename>')
def get_image(filename):
    return '<img src="' + url_for('uploaded_file', filename=filename) + '">'

if __name__ == '__main__':
    app.run()
