问录音文件识别请求,一直报错找不到Action,谁能帮我呀？

测试语音识别中的录音文件识别,一直报错求大神帮忙哦!

请求头的打印信息(从例子里面粘贴的java代码):

curl -X POST https://asr.tencentcloudapi.com -H "Authorization: TC3-HMAC-SHA256 Credential=AKIDYaNvMXe9uPdjhgcbT5SbUAhxxjHfQnSv/2019-12-26/asr/tc3_request, SignedHeaders=content-type;host, Signature=e0c71f62a77845d11fe3a25dfbaec6d9274541dd67cac0df30f2d7ab47e09418" -H "Content-Type: application/json; charset=utf-8" -H "Host: asr.tencentcloudapi.com" -H "X-TC-Action: CreateRecTask" -H "X-TC-Timestamp: 1577362888" -H "X-TC-Version: 2019-06-14" -d '{"EngineModelType":"8k_0","Action":"CreateRecTask","Url":"http%3A%2F%2F122.143.21.62%3A8888%2Fdumwx%2Fvdrom%2F201912%2Fq603-20191113-200009-1573646409.123.mp3","ResTextFormat":0,"SourceType":0,"Version":"2019-06-14","ChannelNum":2}'

请求体的信息:

{"EngineModelType":"8k_0","Action":"CreateRecTask","Url":"http%3A%2F%2F122.143.21.62%3A8888%2Fdumwx%2Fvdrom%2F201912%2Fq603-20191113-200009-1573646409.123.mp3","ResTextFormat":0,"SourceType":0,"Version":"2019-06-14","ChannelNum":2}

返回的报错信息:

{"Response":{"Error":{"Code":"UnknownParameter","Message":"The parameter `Action` is not recognized."},"RequestId":"37ead9ae-e18e-4bc1-8f5b-b3ea51ed8c25"}}

我明明在请求体里面写了Action呀.....真的搞不明白了
