当页面请求的资源被接收时调用此回调。它包含响应作为参数。

响应对象具有以下详细信息 -

  • Id - 请求的资源编号。

  • URL - 请求的 URL。

  • 时间 - 包含响应日期的日期对象。

  • 页眉 - http 页眉。

  • BodySize - 解压缩的接收内容的大小。

  • ContentType - 指定的内容类型(如果已指定)。

  • RedirectURL - 如果存在重定向,则重定向 URL。

  • 阶段 - 值为 - 开始和结束。

  • 状态 - http 代码状态,即状态 200。

  • StatusText - 代码 200 的 http 状态文本,它是 OK。

语法

其语法如下 -

示例

以下代码显示了如何使用 onResourceReceived() 方法。

var wpage = require('webpage').create(); 
wpage.onResourceReceived = function(response) { 
   console.log(JSON.stringify(response));   
} 
wpage.open('https://127.0.0.1/tasks/prompt.html', function(status) {  
}); 

上述程序生成了以下的 输出
