在开放的API接口中为了保证数据的安全性,我们往往采用数字签名的方式对请求进行加密

功能

  • Sign签名
  • 应用授权
  • 用户授权

错误参数

全局返回参数说明 1 Success 操作成功 100000 NULL Null值错误 100001 SIGN_ERROR 签名验证失败 100002 APP_AUTH_ERROR 应用授权失败 100003 USER_AUTH_ERROR 用户授权失败 100004 SYSTEM_ERROR 系统错误 100006 Failed 服务器操作失败

参数说明

1.系统参数 [method]:商户要调用的App接口名称 timestamp:时间戳 统一格式yyyyMMddHHmmss app_key:分配给商户的app_key version:对应接口的版本号 sign:签名,对 API 调用参数(除sign外)进行 md5/rsa 加密获得。

注: 1.系统参数在每次请求中都是必须的; 2.应用参数根据调用的接口具体传参; 3.app_secret 仅作加密使用, 为了保证数据安全请不要在请求参数中使用.

Sign签名 调用API 时需要对请求参数进行签名验证,签名方式如下:

  1. 按照请求参数名称将所有请求参数按照字母先后顺序排序得到: keyvaluekeyvalue...keyvalue 字符串 如:将arong=1,mrong=2,crong=3 排序为:arong=1, crong=3,mrong=2 然后将参数名和参数值进行拼接得到参数字符串:arong1crong3mrong2。
  2. 将app_secret加在参数字符串的头部后进行MD5加密 ,加密后的字符串需大写。即得到签名Sign

用户授权

  1. 通过账号和密码登陆授权成功后,系统返回授权Token, Token有效期为30天,每次重新登陆都会生成一个新的Token值.
  2. 将Token加入请求的参数中且参与Sign签名 注: 不需要用户登陆的公共模块无需传入Token进行用户授权
    通常情况下sign签名验证都是必须的。

请求案例 获取产品列表举例: 方法名称:GetProducts 请求权限:签名验证 参数:pageindex,pagesize 请求方式:get eg:

  1. 按照规则生成签名 参数排序后将app_secret加在字符串头部得到参数字符串: 212821ec2035d78f524a86da13a9dceeapp_key076ba2bcb4a0cb38ce721cc00d27426bpageindex1pagesize10timestamp20150507162828

如上所示 请求所需的4个参数组成的参数字符串,接下来进行MD5加密 得到签名Sign=bcc7c71cf93f9cdbdb88671b701d8a35 记得要大写 这才是正确的签名:Sign=BCC7C71CF93F9CDBDB88671B701D8A35

(可将上面的参数字符串进行MD5加密检测你的加密结果是否一致)
