java - 如何使用 JSOUP 或 Coldfusion 从 URL 中删除查询字符串和哈希值？

Question

示例如下:

当我解析 HTML 页面时。我收到重复的 URL 值，例如

• https://stackoverflow.com/questions/tagged/java?sort=featured&pageSize=50
• https://stackoverflow.com/questions/tagged/java#comments
• https://stackoverflow.com/questions/tagged/java#comment212

如何避免上述重复值？

我只需要这个 URL https://stackoverflow.com/questions/tagged/java

Answer 1

我创建了一个辅助方法 processURL()，它接受一个 URL 并返回一个包含查询标记 (?) 或井号 (#):

String processURL(String theURL) {
    int endPos;
    if (theURL.indexOf("?") > 0) {
        endPos = theURL.indexOf("?");
    } else if (theURL.indexOf("#") > 0) {
        endPos = theURL.indexOf("#");
    } else {
        endPos = theURL.length();
    }

    return theURL.substring(0, endPos);
}

String urlOne = "http://stackoverflow.com/questions/tagged/jav?#sort=featured&pageSize=50";
String urlTwo = "http://stackoverflow.com/questions/tagged/java#comments";

System.out.println(processURL(urlOne));
System.out.println(processURL(urlTwo));

输出:
