接口测试http的get和post请求，键值对和json传参的处理，cookie的保留

        BasicClientCookie basicClientCookie = new BasicClientCookie("JSESSIONID",JSESSIONID);
        basicClientCookie.setVersion(0);
        basicClientCookie.setDomain("127.0.0.1");//Cookie中的setDomain()主要用来在两个不同名称但是后缀相同的网站地址上.这样两个网站就能使用同一个cookie了
        basicClientCookie.setPath("/CwlProClient");//setPath()主要用来确定什么后缀下能够使用这个cookie.即地址栏上面的地址的约束
        cookieStore.addCookie(basicClientCookie);//设置Cookie所遵从的协议版本[默认版本0（遵从原先的Netscape规范）

    }
}

这里的get和post请求，直接返回了HttpResponse类型的response用于后面的数据校验，通过JsonPath来提取校验；

其中post请求，传参可以直接传String类型的键值对，然后用FormatProcessing来处理；传参为嵌套了map的话，通过gson来转化；

最后是cookie的处理，获取后把他传回去全局变量里面去使用；
