如何使用 Java 中的 RegEx 模式检查 LinkedIn 网站 link？

Question

有人可以帮我吗？我正在 linked in url in java 中进行验证。我创建了一个正则表达式（我不熟悉）来验证 link 但是我正在努力解决它。

代码如下：

public class TestRegEx {

    public static void main(final String[] args) {

        // List of valid URLs
        List<String> validValues = new ArrayList<>();
        validValues.add("https://www.linkedin.com/sometext");
        validValues
                .add("https://uk.linkedin.com/in/wiliam-ferraciolli-a9a29795");
        validValues.add("https://it.linkedin.com/hp/");
        validValues.add("https://cy.linkedin.com/hp/");
        validValues
                .add("https://www.linkedin.com/profile/view?id=AAIAABQnNlYBIx8EtS5T1RTUbxHQt5Ww&trk=nav_responsive_tab_profile");


        // List on invalid URLs
        List<String> invalidValues = new ArrayList<>();
        invalidValues.add("http://www.linkedin.com/sometext");
        invalidValues.add("http://whosebug.com/questions/ask");
        invalidValues.add("google.com");
        invalidValues.add("http://uk.linkedin.com/in/someDodgeAddress");
        invalidValues.add("http://dodge.linkedin.com/in/someDodgeAddress");

        // Pattern
        String regex = "(https://)(.+)(www.)(.+)$";
        Pattern pattern = Pattern.compile(regex);

        for (String s : validValues) {
            Matcher matcher = pattern.matcher(s);
            System.out.println(s + " // " + matcher);
        }

    }
}

谁能帮我创建一个正则表达式来验证以下内容 前缀： "https://" 可选前缀： "uk."（可以什么都不是，也可以是其他国家） 中间： "linkedin.com/" 后缀："any characters with a max of 200 chars"

Answer 1

我会选择：

^https:\/\/[a-z]{2,3}\.linkedin\.com\/.*$

LiveDemo

^ assert position at start of a line
https: matches the characters https: literally (case insensitive)
\/ matches the character / literally
\/ matches the character / literally
[a-z]{2,3} match a single character present in the list below

    Quantifier: {2,3} Between 2 and 3 times, as many times as possible, giving back as needed [greedy]
    a-z a single character in the range between a and z (case insensitive)

\. matches the character . literally
linkedin matches the characters linkedin literally (case insensitive)
\. matches the character . literally
com matches the characters com literally (case insensitive)
\/ matches the character / literally
.* matches any character (except newline)

    Quantifier: * Between zero and unlimited times, as many times as possible, giving back as needed [greedy]

$ assert position at end of a line

Answer 2

更新正则表达式

link /in

中的配置文件更改

http(s)?:\/\/([\w]+\.)?linkedin\.com\/in\/[A-z0-9_-]+\/?
