Java JSoup错误提取URL(Java JSoup error fetching URL)

Java JSoup错误提取URL(Java JSoup error fetching URL)

我正在创建一个应用程序，它可以让我从特定网站获取值到控制台。 该值来自<span>元素，我正在使用JSoup 。

我的挑战与此错误有关：

获取URL时出错

这是我的Java代码：

public class TestSl { public static void main(String[] args) throws IOException { Document doc = Jsoup.connect("https://stackoverflow.com/questions/11970938/java-html-parser-to-extract-specific-data").get(); Elements spans = doc.select("span[class=hidden-text]"); for (Element span: spans) { System.out.println(span.text()); } } }

这是控制台上的错误：

线程“main”中的异常org.jsoup.HttpStatusException：HTTP错误提取URL。 Status = 403，URL = Java Html解析器提取特定数据？ at org.jsoup.helper.HttpConnection $ Response.execute（HttpConnection.java:590）org.jsoup.helper.HttpConnection $ Response.execute（HttpConnection.java:540）at org.jsoup.helper.HttpConnection.execute（HttpConnection） .java：227）在testSl.main的org.jsoup.helper.HttpConnection.get（HttpConnection.java:216）（TestSl.java:19）

我做错了什么，如何解决？

I'm creating an application which will enable me to fetch values from a specific website to the console. The value is from a <span> element and I'm using JSoup.

My challenge has to do with this error:

Error fetching URL

Here is my Java code:

public class TestSl { public static void main(String[] args) throws IOException { Document doc = Jsoup.connect("https://stackoverflow.com/questions/11970938/java-html-parser-to-extract-specific-data").get(); Elements spans = doc.select("span[class=hidden-text]"); for (Element span: spans) { System.out.println(span.text()); } } }

And here is the error on Console:

Exception in thread "main" org.jsoup.HttpStatusException: HTTP error fetching URL. Status=403, URL=Java Html parser to extract specific data? at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:590) at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:540) at org.jsoup.helper.HttpConnection.execute(HttpConnection.java:227) at org.jsoup.helper.HttpConnection.get(HttpConnection.java:216) at TestSl.main(TestSl.java:19)

What am I doing wrong and how can I resolve it?

最满意答案

设置用户代理标头：

.userAgent("Mozilla")

例：

Document document = Jsoup.connect("https://stackoverflow.com/questions/11970938/java-html-parser-to-extract-specific-data").userAgent("Mozilla").get(); Elements elements = document.select("span.hidden-text"); for (Element element : elements) { System.out.println(element.text()); }
