PhantomJS - deleteCookie()

DeleteCookie () 将有助于删除一个 cookie，其名称与给定页面 URL 的现有 cookie 列表相匹配。

语法

以下为语法 −

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

示例

以下示例演示了 **deleteCookie** 方法的用途。

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('https://127.0.0.1/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(); 
});

以上的程序生成以下 **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" : 
"Roy"}]
