概述

本文主要为您介绍移动推送签名认证方法。
采用 HMAC-SHA256 算法,根据 SecretKey 生产签名信息。通过校验签名进行鉴权,安全性更好,推荐使用。

参数说明

参数
说明
AccessId
移动推送后台分配的应用 ID,请前往 移动推送控制台 > 产品管理 > 基础配置获取
SecretKey
移动推送后台分配的 SecretKey,与 AccessId 对应,请前往 移动推送控制台 > 产品管理 > 基础配置获取
Sign
接口签名方式
TimeStamp
请求时间戳,单位:s(秒)

签名生成方式

1. 通过请求时间戳 + AccessId + 请求 body 进行字符拼接,得到原始的待签名字符串: 待签名字符串 = ${TimeStamp} + ${AccessId} + ${请求body}
2. 通过 SecretKey 作为密钥,对原始待签名字符串进行签名,生成得到签名: Sign = Base64(HMAC_SHA256(SecretKey, 待签名字符串))

HTTP 协议拼装方式

HTTP 协议 header 中 除了通用头部协议外,需要携带当前请求时间戳、 AccessId、 以及签名 Sign 信息,具体参数如下:
Header 中参数 Key
含义
是否必须
Sign
请求签名
AccessId
应用 ID
TimeStamp
请求时间戳,单位:s(秒)
具体 HTTP 请求报文如下:
POST /v3/push/app HTTP/1.1
Host: api.tpns.tencent.com
Content-Type: application/json
AccessId: 1500001048
TimeStamp: 1565314789
Sign: Y2QyMDc3NDY4MmJmNzhiZmRiNDNlMTdkMWQ1ZDU2YjNlNWI3ODlhMTY3MGZjMTUyN2VmNTRjNjVkMmQ3Yjc2ZA==
{"audience_type": "account","message": {"title": "test title","content": "test content","android": { "action": {"action_type": 3,"intent": "xgscheme://com.xg.push/notify_detail?param1=xg"}}},"message_type": "notify","account_list": ["5822f0eee44c3625ef0000bb"] }

签名生成示例

1. 生成待拼接签名字符串如下:
待加密字符串=15653147891500001048{"audience_type": "account","message": {"title": "test title","content": "test content","android": { "action": {"action_type": 3,"intent": "xgscheme://com.xg.push/notify_detail?param1=xg"}}},"message_type": "notify","account_list": ["5822f0eee44c3625ef0000bb"] }
说明
待签名字符串中的 ${请求body} 和发送数据必须保持一致,包括空格、数据编码等。
2. 根据密钥通过 HMAC-SHA256 算法,生成十六进制 hash,其中示例对应 secretKey =1452fcebae9f3115ba794fb0fff2fd73
hashcode= hmac-sha256(SecretKey, 待签名字符串)
得到 hashcode="09f07d2a518a8814e369dcd9534f10b8a29d128531a19adaa28cb247605c1e84"
3. 对 hashcode 进行 base64 编码,得到签名串如下:
得到 Sign=Base64(hashcode)
Sign="MDlmMDdkMmE1MThhODgxNGUzNjlkY2Q5NTM0ZjEwYjhhMjlkMTI4NTMxYTE5YWRhYTI4Y2IyNDc2MDVjMWU4NA=="
