var webPage = require('webpage');
var page = webPage.create();
page.onResourceReceived = function(response) {
  console.log('Response (#' + response.id + ', stage "' + response.stage + '"): ' + response.url);
};

var url='https://v.alltuu.com/album/1044306477/1017026202/';
page.open(url, function start(status) {
  page.render('snap.jpeg', {format: 'jpeg', quality: '100'});
  phantom.exit();
});

u.push.bind(u) 这是什么用法 是不是phantomjs不支持 浏览器打开页面是可以运行的

我也 不懂,帮顶

phantomjs 和浏览器都支持,就是函数绑定啊。你还是把具体的错误信息贴出来吧
