大家好，又见面了，我是你们的朋友全栈君。
废话不多说，直接上代码。
功能：随便截取一个url页面：
https://www.baidu.com/s?word=phantomjs+%E6%88%AA%E5%9B%BE&tn=43061099_196_hao_pg&ie=utf-8&ssl_sample=hao_1
phantomjs的js环境test.js
system = require(‘system’)
address = system.args[1];//获得命令行第二个参数 接下来会用到
//console.log(‘Loading a web page’);
var page = require(‘webpage’).create();
var url = address;
//console.log(url);
page.open(url, function (status) {
//Page is loaded!
if (status !== ‘success’) {
console.log(‘Unable to post!’);
} else {
//console.log(page.content);
//var title = page.evaluate(function() {
// return document.title;//示范下如何使用页面的jsapi去操作页面的 www.oicqzone.com
// });
//console.log(title);
console.log(‘ok’);
page.render(‘e:/phantomjs/example.png’);
}
phantom.exit();
});
java调用外部程序代码：
public class PhantomTest {
public static String getAjaxCotnent(String url) throws IOException {
Runtime rt = Runtime.getRuntime();
Process p = null;
try {
p = rt.exec(“D:/phantomjs-2.0.0-windows/bin/phantomjs.exe e:/phantomjs/test.js “+url);
} catch (IOException e) {
e.printStackTrace();
}
InputStream is = p.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
StringBuffer sbf = new StringBuffer();
String tmp = “”;
while((tmp = br.readLine())!=null){
sbf.append(tmp);
}
System.out.println(“a”+sbf);
System.out.println(sbf.toString());
return sbf.toString();
}
public static void main(String[] args) throws IOException {
getAjaxCotnent(“https://www.baidu.com/s?word=phantomjs+%E6%88%AA%E5%9B%BE&tn=43061099_196_hao_pg&ie=utf-8&ssl_sample=hao_1”);
}
}
