Step 1. 联系客服（0755-84362888）或者进入信用云官网提交信息联系我们来获取测试的apiKey 和apiSecret

Step 2. 获取apiKey 和apiSecret后，利用文档完成接口的开发和调试

Step 3. 联系客服获取正式的apiKey和apiSecret完成上线操作

              
  apiKey: (第三方app-key，是三方开发者系统的唯一标示)
            
  secret: (第三方开发人员调用信用云openapi时用于计算签名的参数.请妥善保管)

              
  200表示调用成功
  
  500，502表示系统内部错误，可稍后再试
  
  401表示未授权
  
  403表示签名验证失败
  
  400表示业务处理错误.
              

              
  {
      "code": "CM10000",//返回错误码
      "errorMessage": null,//错误信息
      "data": "pass",//返回数据
      "success": true //请求是否成功.
  }

              

              
  以企业工商基本信息接口为例(/api/v1/enterprise/basic/base-info)
              

              
  例如：uri=/api/v1/enterprise/basic/base-info
  apiKey=ntjhb0v6thrwaujqttytbzayow5ozw
  timestamp=1572416299710
  secret=m2i5oddjmgzhmgi0ndk2m2jhytjkmznjmzdhymfkmwq
  拼接之后的结果为：/api/v1/enterprise/basic/base-info?apiKey=ntjhb0v6thrwaujqttytbzayow5ozw×tamp=1572416299710m2i5oddjmgzhmgi0ndk2m2jhytjkmznjmzdhymfkmwq

              

              
  上述拼接好的字符串的MD5签名结果为 
  c617b53e9b61e54cfe851a869890fc6e
