PhantomJS - onResourceReceived()

当收到页面请求的资源时，将调用此回调。它包含响应作为参数。

响应对象具有以下详细信息 −

• 请求的资源的 ID − 编号。

• URL − 请求的 URL。

• Time − 包含响应日期的日期对象。

• Headers − http 标头。

• BodySize − 解压缩后的接收内容的大小。

• ContentType − 如果指定，则为内容类型。

• 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 − 代码为 200 的 http 状态文本，表示正常。

语法

其语法如下 −

page.onResourceReceived = function(response) {}

示例

以下代码显示了 onResourceReceived() 方法的使用。

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

上述程序生成以下输出。
