鉴权失败错误提示 (๑•̀ㅂ•́)و✧
哎呀呀～遇到鉴权错误啦！ (⊙_⊙) 快来看看是哪里出问题了吧～
| HTTP Code | 错误描述 | 原因 | 处理建议 |
|---|---|---|---|
| 401 | {"message":"Unauthorized"} |
缺少 authorization 参数 | 哎呀～检查一下有没有正确带上传入的 authorization 参数哦～ |
| 401 | {"message":"HMAC signature cannot be verified"} |
签名参数解析失败 | 嗯嗯～ (°∀°)ﾉ 检查一下各签名参数是否完整，确认 APIKey 是不是正确呀～ |
| 401 | {"message":"HMAC signature does not match"} |
签名校验失败 | 嘿呀～ (｡•́︿•̀｡) 检查一下 APIKey/APISecret 是否正确呢～还要看看 host、date、request-line 拼接对不对哦～signature 的 Base64 长度正常应该是 44 字节呢～ |
| 403 | {"message":"HMAC signature cannot be verified, a valid date or x-date header is required"} |
时钟偏移校验失败 | 嗯嗯？ (⊙_⊙) 服务器时钟可能有偏差哦～偏差超过 300 秒就会被拒绝啦！快去校准一下时间吧～ |
小贴士 💡：
- 如果遇到签名不匹配的错误，首先检查 APIKey 和 APISecret 是否正确～
- 确保服务器的日期时间准确，偏差太大会导致 403 错误哦～
- 签名中的 path 需要和实际请求的路径完全一致才可以呢～
Tips
- Video URL: Must be an OSS (Aliyun Object Storage Service) URL accessible by iFlytek
- Task status: Use get_task to check task progress
- Completed tasks: When status is "completed", the output_video_url contains the translated video
- Manual intervention: Some videos may require human review for transcript or translation
