调用百度音频，文字转音频
flask发送文字请求，得到音频响应，写入BytestIo返回前端
text = request.args.get("text").encode("utf-8")retData = getVoice(text)ls_f1 = base64.b64decode(retData)by = BytesIO(ls_f1)return send_file(by, mimetype='audio/mpeg')
text = request.args.get("text").encode("utf-8")retData = getVoice(text)ls_f1 = base64.b64decode(retData)by = BytesIO(ls_f1)return send_file(by, mimetype='audio/mpeg')
