cos-wx-sdk-v5 Access Denied

使用cos-wx-sdk-v5 的putObject方法，一直报错

"error": {

"Code": "AccessDenied",

"Message": "Access Denied.",

"ServerTime": "2020-07-08T08:16:45Z",

"Resource": "xxxxx-xxxxx-xxxxxx.cos.ap-guangzhou.myqcloud.com/audio/6d481bcd3c49b8c0eb6a91ae871bf656.txt",

"RequestId": "NWYwNTgwZWNfZDVhNDYyNjRfNmU1OF8xZDQ3Y2Y4",

"TraceId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

},

postObject没问题。

putObject使用主账号还是报错。
