PhantomJS deleteCookie()

PhantomJS deleteCookie()

DeleteCookie()方法将帮助删除与给定页面URL的现有cookie列表中名称匹配的cookie。

语法

其语法如下 –

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

示例

以下示例展示了 deleteCookie 方法的使用。

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 输出 。

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" :
