Answer 1

当您只想匹配参数的值时，您可以使用looks围绕围绕值匹配的值并用xx或任何您想要的任何东西替换它们。

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

演示

查看此Java代码，

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"));
    });

打印，
