page.open('http://www.httpuseragent.org', function(status) {
if (status !== 'success') {
console.log('Unable to access network');
} else {
var ua = page.evaluate(function() {

All you have to do is to use page.content
您所要做的就是使用 page.content
var page = require('webpage').create();
page.onError = function(msg, trace) {
//prevent js errors from showing in page.content
return;
};
page.open('http://www.httpuseragent.org', function () {
console.log(page.content); //page source
phantom.exit();
});
