后台服务端接口验证项目实例~~

前言：

    在当前开放互联的大环境下，接口互通成了最最普通常见数据通讯与交互的一种方式；接口测试的重要性也是不言而喻，但却成了普通功能测试人员的一道屏障；特别是服务端的接口验证更是麻烦；这里抛砖引玉希望更多童鞋参与多多讨论。

场景&描述：

    c1->s1->s2

          s1 <-s2

协议：http

c端，发起c1（pay）请求，服务端处理完毕，通过s1接口把（pay）请求支付接口告诉指定s2服务地址；s2服务地址解析s1接口内容，正常返回SUCCESS,异常返回FAILURE;s1收到s2返回内容做对应业务处理。

接口消息格式：json，签名验签rsa标准算法，消息体url编码。

请求方式：post

测试对象：

   s1接口

测试范围：

接口测试之常规测试维度，从宏观到微观一一细分拆借大概思路：消息发送方式、消息体是否为null、消息体格式是否正确、消息解密是否正确、消息体中json体key键检查（必填值是否缺省、缺省值是否存在、是否多多余key键）、消息体中json体values值检查（必填值检查是否缺省、缺省值是否存在、值类型检查，特别是数字类型的，比如交易金额啥的）。

接口测试之安全维度，ip黑白名单，消息体参数注入，摘要解密算法研究等。

1.消息发送方式

2.消息体是否为null和格式检查

3.json，key键必填字检查

4.json,values值检查

5.业务数据检查，比如收到SUCCESS检查。

6.其它

实现技术分析：

如果只要验证第5点，简单的只要模拟s2，最快速高效的方法，直接在tomcat下，新建一个工程，创建一个html文件，内容为SUCCESS或FAILURE；然后s1接口直接往这个地址发送就好（http协议）。

http协议，后台实现，最方便的还是java，也有python的，依赖的包太多，看个人条件选择；如果是soket套接字，建议与加密解密类语言保持一致比较好，因为解密太折腾人了，哎。

这里选择了一个java,servlet来实现。

再回头看s1接口，所以的参数都不是固定的，每次发生请求的参数都是动态的，这样的话，自己去实现这个servlet的时候，参数化的部分，就直接考虑连接db，这样就不需要考虑s1接口传入固定的值，动态的去db查询s1接口参数相关数据信息（特别是解密，与json,values值验证，和功能业务特性，每次填写固定参数值肯定不靠谱）。
