HTTP/HTTPS 请求时，请求报文中需包含签名信息（X-TC-Signature）以验证请求者身份。curl -X POST https://ap-guangzhou.gateway.tencentdevices.com/device/register \\-H "Content-Type: application/json; charset=utf-8" \\-H "X-TC-Algorithm: hmacsha256" \\-H "X-TC-Timestamp: 155****065" \\-H "X-TC-Nonce: 5456" \\-H "X-TC-Signature: 2230eefd229f582d8b1b891af****b91597240707d778ab3738f756258d7652c" \\-d '{"ProductId":"ASJ****GX","DeviceName":"xyz"}'

参数名称 | 描述 |
HTTPRequestMethod | HTTP 请求方式， 支持 POST |
CanonicalHost | HTTP 请求的 Host 地址 |
CanonicalURI | HTTP 请求 URI 。例如 https://ap-guangzhou.gateway.tencentdevices.com/device/register 的 URI 为 /device/register |
CanonicalQueryString | 发起 HTTP 请求 URL 中的查询字符串，对于 POST 请求，固定为空字符串 "" |
Algorithm | 签名方法。目前支持 HmacSha256 和 HmacSha1 |
RequestTimestamp | 请求时间戳 |
Nonce | 随机数 |
HashedCanonicalRequest | 请求正文 Hash 值。HTTP 请求正文做 SHA256 哈希，然后十六进制编码，最后编码串转换成小写字母 |

Signature = Base64_Encode(HMAC_SHA256(SignSecret, StringToSign))
参数名称 | 描述 |
SignSecret | 签名密钥，如动态注册使用 ProductSecret，设备发布消息或上报日志则使用 psk |
StringToSign | 待签名的字符串 |
Signature = Base64_Encode(RSA_SHA256(PrivateKey, StringToSign))
参数名称 | 描述 |
PrivateKey | 证书私钥，如设备发布消息或上报日志则使用设备的 X509 私钥证书 |
StringToSign | 待签名的字符串 |
