当接收到页面请求的资源时调用此回调。它包含 response 作为参数。

响应对象具有以下详细信息 -

• Id- 请求资源的数量。

• URL- 请求的 URL。

• Time− 包含响应日期的日期对象。

• Headers- http 标头。

• BodySize− 接收到的内容解压后的大小。

• ContentType- 内容类型(如果指定)。

• RedirectURL− 如果有重定向，则为重定向的 URL。

• Stage− 值为 - 开始和结束。

• Status- http 代码状态，即状态 200。

• StatusText- code 200的http状态文本，可以。

用法

它的语法如下 -

page.onResourceReceived = function(response) {}

示例

下面的代码展示了使用onResourceReceived()方法。

var wpage = require('webpage').create(); 
wpage.onResourceReceived = function(response) { 
   console.log(JSON.stringify(response));   
} 
wpage.open('http://localhost/tasks/prompt.html', function(status) {  
});

上述程序生成以下内容output。
