2、
将请求信息复制到http请求的 Body Data里；
3、
填写好服务器名称或IP、路径、方法、编码方式；
4、创建一个用户定义的变量，并把请求里固定不变的变量放在里面，如图按名称和值来存放；便于统一修改；
5、在接口里把用户自定义变量引用进来；按变量格式引用；
6、创建一个BeanShell PreProcessor，将接口请求里的时间戳和uuid抽到这里，生成随机值并赋值给变量；
long timestamp = System.currentTimeMillis(); 获取系统当前时间。
vars.put("timestamp",timestamp+"");将当前时间赋值给timestamp变量；接口请求里可以通过${timestamp}引用；注意vars.put(String,String)必须传入字符串，时间戳需要格式转化为字符串，所以写成：timestamp+""；
String paymentUuid = UUID.randomUUID().toString().replaceAll("-", ""); 随机生成UUID并赋值给paymentUuid;
vars.put("paymentUuid",paymentUuid);将当前时间赋值给paymentUuid变量；接口请求里可以通过${paymentUuid}引用；
7、在接口请求里，引用uuid；
8、
针对tradeNo ，为了便于区别接口测试产生的数据与非接口操作产生的数据，在tradeNo上做一个区分；所以用一个固定数字开头；用时间结束；如下图定义；
9、在接口请求内容里引用tradeNo,如图所示；
10、运行：可以看到操作成功提示；
11、问题1：运行时提示，数据验证失败；
查看请求，发现传的参数有空格，导致不能识别；修改参数即可；
12、
问题2：响应的数据有乱码；
查看http请求设置，未填写Content encoding；由于传入的请求里有中文字符，所以需要填写Content encoding：utf-8;
