写一段python代码，举例如何通过Flask向uni-app标签，传递wav音频

from flask import Flask, request, render_template app = Flask(__name__) @app.route('/sendwav', methods=['POST'])
def send_wav():
wav_data = request.files['wav_data']
# 将音频文件保存到服务器
wav_data.save('path/to/server/wav_data.wav')
# 将接收到的音频文件传递给uni-app标签
return render_template('send_wav.html', wav_data='path/to/server/wav_data.wav') if __name__ == '__main__':
app.run()
