请求体示例
{
"languageCode": "zh-CN",
"config": {
"codec": "AMR_WB",
"sampleRateHertz": 16000
},
"audio":"T2dnUwACAAAAAAAAAAAd8pVTAAAAAGsIvpMBE...",
"alternativeLangCodes": ["en-US", "th-TH","id-ID"]
}
请求签名：
当用户请求Speech Recognition API时，可以使用appId和secretKey对请求做签名，当API收到带签名信息的请求之后，将使用相同的算法验证签名，如果发现签名不一致，API将会返回401给用户。
如果API验证签名一致，且appId对应的用户有权限操作请求的资源，则请求成功，否则API返回401。
通过 HTTP 请求 Header 发送签名
方法: 在请求中加入名为 Authorization 的 Header，值为签名值。如下：
Authorization: Njl86M/jY6zZaZoGhZdGO+GI/8+yGFECusGH1yQHUFE=
签名计算方法
1.构造规范化的请求字符串（Canonicalized Query String）
将请求体JSON字符串以UTF-8字符编码做sha256编码后转换为16进制字符串（注意不是Base64）
CanonicalizedQueryString = hex(sha256(jsonBody))
2.构造被签名字符串 StringToSign ("\n” 代表ASCII里的换行符)
StringToSign = HTTPMethod + "\n" +
HostHeaderInLowercase + "\n" +
HTTPRequestURI + "\n" +
CanonicalizedQueryString <从上一步得到> + "\n" +
"X-AppId:" + SAME_APPID_IN_HEADER + "\n" +
"X-TimeStamp:" + SAME_TIMESTAMP_IN_HEADER
HTTPRequestURI是请求URI的绝对路径，不包含请求串。如果HTTPRequestURI为空，也要保留一个正斜杠 ( / )
使用 HMAC-SHA256 协议创建基于哈希的消息身份验证代码 (HMAC)，然后计算签名。
3.StringToSign作为签名字符串，secretKey作为秘钥，SHA256作为哈希算法
有关 HMAC 的更多信息，请参阅 https://tools.ietf.org/html/rfc2104。
4.将上一步的结果转换为BASE64串
5.将BASE64串放入HTTP请求Header的Authorization

参数规范
请求URL： https://asr.ilivedata.com/api/v1/speech/recognize
HTTP请求Header：
| Header | 值 | 描述 |
|---|---|---|
| Content-Type | application/json;charset=UTF-8 | 请求体类型 |
| Accept | application/json;charset=UTF-8 | 接受的返回类型 |
| X-AppId | 项目或应用的唯一标识符 | |
| X-TimeStamp | 请求的UTC时间戳。需要把时间戳按W3C标准格式化，例如: 2010-01-31T23:59:59Z. (http://www.w3.org/TR/xmlschema-2/#dateTime)。 | |
| Authorization | 签名值 |
请求方法：POST
请求体：
| 参数 | 子参数 | 必需 | 描述 |
|---|---|---|---|
| languageCode | 必需 | 音频对应的语种 支持语种 | |
| audio | 必需 | Base64格式的音频文件 | |
| config | codec | 可选 | 编码格式，支持AMR、AMR_WB、OPUS、PCM。如未指定则默认使用AMR_WB |
| sampleRateHertz | 可选 | AMR只支持8000，其余编码格式只支持16000 | |
| userId | 可选 | 唯一的终端用户ID。 用户ID应当不超过32个字符。 | |
| alternativeLangCodes | 可选 | 候选语种数组，最多支持传入4个候选语种 支持语种 | |
| digitalize | 可选 | 中文识别结果转数字，值为 0/1，默认开启（1） |
请求体示例
{
"languageCode": "zh-CN",
"config": {
"codec": "AMR_WB",
"sampleRateHertz": 16000
},
"audio":"T2dnUwACAAAAAAAAAAAd8pVTAAAAAGsIvpMBE...",
"alternativeLangCodes": ["en-US", "th-TH","id-ID"]
}
请求签名：
当用户请求Speech Recognition API时，可以使用appId和secretKey对请求做签名，当API收到带签名信息的请求之后，将使用相同的算法验证签名，如果发现签名不一致，API将会返回401给用户。
如果API验证签名一致，且appId对应的用户有权限操作请求的资源，则请求成功，否则API返回401。
通过 HTTP 请求 Header 发送签名
方法: 在请求中加入名为 Authorization 的 Header，值为签名值。如下：
Authorization: Njl86M/jY6zZaZoGhZdGO+GI/8+yGFECusGH1yQHUFE=
签名计算方法
1.构造规范化的请求字符串（Canonicalized Query String）
将请求体JSON字符串以UTF-8字符编码做sha256编码后转换为16进制字符串（注意不是Base64）
CanonicalizedQueryString = hex(sha256(jsonBody))
2.构造被签名字符串 StringToSign ("\n” 代表ASCII里的换行符)
StringToSign = HTTPMethod + "\n" +
HostHeaderInLowercase + "\n" +
HTTPRequestURI + "\n" +
CanonicalizedQueryString <从上一步得到> + "\n" +
"X-AppId:" + SAME_APPID_IN_HEADER + "\n" +
"X-TimeStamp:" + SAME_TIMESTAMP_IN_HEADER
HTTPRequestURI是请求URI的绝对路径，不包含请求串。如果HTTPRequestURI为空，也要保留一个正斜杠 ( / ) 使用 HMAC-SHA256 协议创建基于哈希的消息身份验证代码 (HMAC)，然后计算签名。
3.StringToSign作为签名字符串，secretKey作为秘钥，SHA256作为哈希算法
有关 HMAC 的更多信息，请参阅 https://tools.ietf.org/html/rfc2104。
4.将上一步的结果转换为BASE64串
5.将BASE64串放入HTTP请求Header的Authorization
