JSoup没有显示正确的文本 [英] JSoup not showing correct text

问题描述

因此，我想创建一个Java应用程序，该应用程序将爬网名为chillstep.info的网站的Songname并将其保存到.txt文件中.但是，JSoup将其打印出来:
<div id="titel"> ♫ </div>

So I wanted to create a Java App which crawls the Songname of a website called chillstep.info and saves it into a .txt file. However JSoup prints this out:
<div id="titel"> ♫ </div>

这是代码:

public class Crawltitle {

    public static void getTitle() throws IOException{
        Document doc = Jsoup.connect("http://chillstep.info/").get();
        String title = doc.getElementById("titel").outerHtml();
        System.out.println(title);
    }

    public static void main(String[] args) throws IOException{
        getTitle();
    }
}   

这个问题是由于网站(如果是，为什么以及如何解决该问题)或JSoups造成的吗?

Is this problem because of the website (if yes, why and how to solve that problem) or JSoups?

推荐答案

标题通过

http://chillstep.info/jsonInfo.php

如果忽略通常允许的内容类型，您仍然可以使用Jsoup来获取它:

You still can use Jsoup to get this, if you ignore the usually allowed content type:

Connection con = Jsoup
   .connect("http://chillstep.info/jsonInfo.php")
   .ignoreContentType(true);    
Response res = con.execute();
String rawJSON = res.body();

请注意，我没有使用JSoup解析器.因此，您可能还使用了其他任何库来获取HTTP内容，例如Apache HtmlClient或此类.

Note that I did not use the JSoup parser. So you might as well have used any other library to get HTTP content, like Apache HtmlClient or such.

这时，您可以使用您选择的json库解析answser.或者，因为它是如此简单，所以可以手工"完成:

At this point you can parse the answser with a json library of your choice. Or do it "by hand" since it is so simple:

String title = rawJSON.replaceAll(".*:\"([^\"]*).*","$1");
