签名认证（推荐）

最后更新时间：2024-01-17 14:24:51

    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 > 配置管理 > 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 > 配置管理 > 基础配置获取
    Sign
    接口签名方式
    TimeStamp
    请求时间戳，单位s

    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
    是
    AccessId
    应用 ID
    是
    TimeStamp
    请求时间戳
    是
    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=="
