PhantomJS onResourceTimeout()|极客教程

PhantomJS onResourceTimeout()

当请求的资源超时时，将调用此回调函数。也就是当使用settings.resourceTimeout回调函数时。

它包含一个参数，即 request 它具有以下详细信息−

Id − 请求资源的编号
Method − HTTP方法
URL − 请求资源的URL
Time − 包含请求日期的日期对象
Headers − HTTP头列表
ErrorCode − 错误的错误代码
ErrorString − 错误的文本消息

语法

其语法如下−

page.onResourceTimeout = function(request) {}

示例

var wpage = require('webpage').create(); 
wpage.onResourceTimeout = function(request) { 
   console.log("Data from request:"); 
   console.log(JSON.stringify(request)); 
} 
wpage.settings.resourceTimeout = '3'; 
wpage.open('http://localhost/tasks/request.html', function(status) { 
});

上面的程序生成以下输出。

Data from request: 
{"errorCode":408,"errorString":"Network timeout onresource.",
"headers":[{"name":"Accept","value":"text/html,application/xhtml+xml ,
application/xml;q=0.9,*/*;q=0.8"},{"name":"User-Agent","value":"Mozilla/5.0 
(Windows NT 6.2; WOW64) AppleWebKit/538.1 (KHTML, like Gecko) 
PhantomJS/2.1.1 Safari/538.1"}],"id":1,
"method":"GET","time":"2017-0507T13:32:12.545Z",
"url":"http://localhost/tasks/request.html" 
}
