    推荐答案

    您可以按以下方式使用正则表达式:

    You can use the regex as below:

    ^(?=.{8,50}$)(?=(.*?[a-z].*?[A-Z])|(.*?[a-z].*?[0-9])|(.*?[a-z].*?[!@#$%^&*()_+])|(.*?[A-Z].*?[0-9])|(.*?[A-Z].*?[!@#$%^&*()_+])|(.*?[0-9].*?[!@#$%^&*()_+])).*$
    

    Debuggex演示

    我尝试的是:

    Lowercase - Uppercase   (.*?[a-z].*?[A-Z])            // Valid Entry
    Lowercase - Number      (.*?[a-z].*?[0-9])            // Valid Entry
    Lowercase - Symbol      (.*?[a-z].*?[!@#$%^&*()_+])   // Valid Entry
    
    Uppercase-Number        (.*?[A-Z].*?[0-9])            // Valid Entry
    Uppercase-Symbol        (.*?[A-Z].*?[!@#$%^&*()_+])   // Valid Entry
    
    Number-Symbol           (.*?[0-9].*?[!@#$%^&*()_+])   // Valid Entry
