给学生充值-需要用到登录cookie的接口
在headers中添加登录的cookie，如果是不同的用户的cookie，可以对用户的cookie进行关联，在充值接口中调用该关联的参数
这个用jmeter来操作，必填项为stu_id gold 都是int类型
登录的服务器返回结果为：
|
{
"error_code": 0,
"login_info": {
"login_time": "20180815163827",
"sign": "d5eb0557e5e8c880ec8b04469bbf0a54",
"userId": 9234
}

可以在登录 添加 正则表达式来提取cookie；也可以添加一个Extractor 来提取
Add http header information added cookie manager ---- --- If a plurality of users may be extracted cookie above by way of FIG. 2, the user needs to different users parameterized graph wawawa the need to do a parameterization, and the need to retain login operation;
A single user, then, http header Manager - simply write wawawa = cookie value on it
