использование replaceAll () для замены части сопоставленного шаблона

Question

Допустимым шаблоном для захвата значения запроса в URL может быть

\(?|&\)[^=]+=([^&]+)

Как заменить все значение запроса в URL-адресе, используя replaceAll.

Или использовать другие приемы здесь?

Любая помощь будет оценена :))

Answer 1

Поскольку вы хотите просто сопоставить значения параметров, вы можете использовать это регулярное выражение, используя осадки, чтобы сопоставить только значения и заменить их на xx или что угодно.

(?<=[&=])[^=&"\n ]*(?=[&" ]|$)

Проверьте этот код Java,

List<String> list = Arrays.asList("https://stackoverflow.com/questions/54937940?a=5",
            "https://stackoverflow.com/questions/54937940?a=5&b=7", "*266 open() \"/usr/local/nginx/html/user-accounts/malphas/check\" failed (2: No such file or directory), client: 10.254.3.0, server: ji, request: \"GET /user-accounts/malphas/check?sid=ExecAuthoritySetting HTTP/2.0\", host: \"jilcom\", referrer: \"https://jicom/user-accounts/authority/authoritysettings/authoritysetting/detail?sid=ExecAuthoritySetting&roleId=1812\"\"tid\"");
    list.forEach(x -> {
        System.out.println(x + " --> " + x.replaceAll("(?<=[&=])[^=&\"\\n ]*(?=[&\" ]|$)", "xx"));
    });
