        BasicClientCookie basicClientCookie = new BasicClientCookie("JSESSIONID",JSESSIONID);
        basicClientCookie.setVersion(0);
        basicClientCookie.setDomain("127.0.0.1");//Cookie中的setDomain()主要用來在兩個不同名稱但是后綴相同的網站地址上.這樣兩個網站就能使用同一個cookie了
        basicClientCookie.setPath("/CwlProClient");//setPath()主要用來確定什么后綴下能夠使用這個cookie.即地址欄上面的地址的約束
        cookieStore.addCookie(basicClientCookie);//設置Cookie所遵從的協議版本[默認版本0（遵從原先的Netscape規范）

    }
}

這里的get和post請求，直接返回了HttpResponse類型的response用於后面的數據校驗，通過JsonPath來提取校驗；

其中post請求，傳參可以直接傳String類型的鍵值對，然后用FormatProcessing來處理；傳參為嵌套了map的話，通過gson來轉化；

最后是cookie的處理，獲取后把他傳回去全局變量里面去使用；
