打开与Jsoup的连接，获取状态代码并解析文档 [英] Open a connection with Jsoup, get status code and parse document

问题描述

我正在使用jsoup创建一个类，它将执行以下操作：

I'm creating a class using jsoup that will do the following:

1. 构造函数打开与url的连接。


2. 我有一个检查页面状态的方法。即200,404等。


3. 我有一个方法来解析页面并返回一个网址列表。＃

下面是我正在尝试做的粗略工作，而不是非常粗糙，因为我一直在尝试很多不同的事情

Below is a rough working of what I am trying to do, not its very rough as I've been trying a lot of different things

public class ParsePage {
private String path;
Connection.Response response = null;

private ParsePage(String langLocale){
    try {
        response = Jsoup.connect(path)
                .userAgent("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.21 (KHTML, like Gecko) Chrome/19.0.1042.0 Safari/535.21")
                .timeout(10000)
                .execute();
    } catch (IOException e) {
        System.out.println("io - "+e);
    }
}

public int getSitemapStatus(){
    int statusCode = response.statusCode();
    return statusCode;
}

public ArrayList<String> getUrls(){
    ArrayList<String> urls = new ArrayList<String>();

 }
}

如你所见，我可以得到页面状态，但使用构造函数已经打开的连接，我不知道如何解析文档，我尝试使用：

As you can see I can get the page status, but using the already open connection from the constructor I don't know how to get the document to parse, I tried using:

Document doc = connection.get();

但这是不行的。有什么建议？或者更好的方法来解决这个问题？

But that's a no go. Any suggestions? Or better ways to go about this?

推荐答案

如JSoup文档中所述解析（）将响应的主体解析为 Document 并返回它的方法。
当你拥有它时，你可以用它做任何你想做的事。

As stated in the JSoup Documentation for the Connection.Response type, there is a parse() method that parse the response's body as a Document and returns it. When you have that, you can do whatever you want with it.

例如，看看 getUrls（）的实现

public class ParsePage {
   private String path;
   Connection.Response response = null;

   private ParsePage(String langLocale){
      try {
         response = Jsoup.connect(path)
            .userAgent("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.21 (KHTML, like Gecko) Chrome/19.0.1042.0 Safari/535.21")
            .timeout(10000)
            .execute();
      } catch (IOException e) {
         System.out.println("io - "+e);
      }
   }

   public int getSitemapStatus() {
      int statusCode = response.statusCode();
      return statusCode;
   }

   public ArrayList<String> getUrls() {
      ArrayList<String> urls = new ArrayList<String>();
      Document doc = response.parse();
      // do whatever you want, for example retrieving the <url> from the sitemap
      for (Element url : doc.select("url")) {
         urls.add(url.select("loc").text());
      }
      return urls;
   }
}
