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。
