PhantomJS deleteCookie()用法及代码示例

DeleteCookie () 方法将帮助删除名称与给定页面 URL 存在的现有 cookie 列表匹配的 cookie。

用法

其语法如下：

var wpage = require('webpage').create(); 
wpage.deleteCookie(cookiename); 

示例

下面的例子展示了使用deleteCookie方法。

var wpage = require('webpage').create(); 
phantom.addCookie ({ 
   'name'    :'cookie1',    /* mandatory property */ 
   'value'   :'1234',       /* mandatory property */ 
   'domain'  :'localhost',  /* mandatory property */ 
   'path'    :'/', 
   'httponly':true, 
   'secure'  :false, 
   'expires' :(new Date()).getTime() + (5000 * 60 * 60) 
}); 

wpage.open('http://localhost/tasks/a.html', function() { 
   console.log("Cookies available are:"); 
   console.log(JSON.stringify(wpage.cookies));  
   wpage.deleteCookie('cookie1'); 
   console.log("Cookies available now after deleting cookie1"); 
   console.log(JSON.stringify(wpage.cookies)); 
   phantom.exit(); 
});

上述程序生成以下内容output。

Cookies available are:
[{"domain":".localhost","expires":"Sun, 07 May 2017 10:21:04 GMT","expiry":14941 
32664,"httponly":true,"name":"cookie1","path":"/","secure":false,"value":"1234" } 
,{"domain":"localhost","expires":"Fri, 22 Dec 2017 12:00:00 GMT","expiry":151394 
4000,"httponly":false,"name":"username","path":"/tasks/","secure":false,"value":
"Roy"}]  

Cookies available now after deleting cookie1 
[{"domain":"localhost","expires":"Fri, 22 Dec 2017 12:00:00 GMT","expiry":151394 
4000,"httponly":false,"name":"username","path":"/tasks/","secure":false,"value":
