phantomjs 抓取搜狗相关搜索的例子

var page = require('webpage').create();
var system = require('system');

if (system.args.length != 2) {
console.log("input keyword to search!");
} else {
// 设置编码一般使用System不会出错 utf8反而不给力
phantom.outputEncoding = 'System';
// 通过命令行读取搜索参数
address = encodeURI('http://www.sogou.com/web?query=' + system.args[1]);
console.log(address);
try {
var openbaidu = page.open(address, function(status) {
var title = page.evaluate(function() {
// WebKit接口
var res = document.querySelectorAll('#hint_container a');
var res_text = '';
for (i = 0; i < res.length; i++) {
res_text += res[i].innerHTML + "\n";
}
return res_text;
});
console.log(title);
});

openbaidu;
} catch (e) {
console.log(e);
}
}
