1. 错误返回：
       "message": "quota exceeded for types: xxxxxxxxx_lifetime"
   错误原因：试用版用量用完了，需要开通正式版才能继续使用

2. 错误返回：
   "message": "quota exceeded for types: concurrency"
   错误原因：并发超过了限定值，需要减少并发调用情况或者增购并发

3. 错误返回：
       "message": "Fail to feed text, reason Init Engine Instance failed"
   错误原因：voice_type / cluster 传递错误

4. 错误返回：
   "message": "illegal input text!"
   错误原因：传入的text无效，没有可合成的有效文本。比如全部是标点符号或者emoji表情，或者使用中文音色时，传递日语，以此类推。多语种音色，也需要使用language指定对应的语种

5. 错误返回：
   "message": "authenticate request: load grant: requested grant not found"
   错误原因：鉴权失败，需要检查appid&token的值是否设置正确，同时，鉴权的正确格式为
   headers["Authorization"] = "Bearer;${token}"

6. 错误返回：
   "message': 'extract request resource id: get resource id: access denied"
   错误原因：语音合成已开通正式版且未拥有当前音色授权，需要在控制台购买该音色才能调用。标注免费的音色除BV001_streaming及BV002_streaming外，需要在控制台进行下单（支付0元）
