The difference between redirect, jump success and error in Thinkphp

Three methods are passed in at the same time U(MODULE_NAME . '/Public/index') When using this URL parameter,

redirect will generate multiple addresses for index.php, causing access errors, but when using URL_MODEL=2 pseudo-static, there is no problem

View the redirect source code:

/**
 * Action跳转(URL重定向） 支持指定模块和延时跳转
 * @access protected
 * @param string $url 跳转的URL表达式
 * @param array $params 其它URL参数
 * @param integer $delay 延时跳转的时间 单位为秒
 * @param string $msg 跳转提示信息
 * @return void
 */
protected function redirect($url,$params=array(),$delay=0,$msg='') {
    $url    =   U($url,$params);
    redirect($url,$delay,$msg);
}

Because redirect requires a string and not an address generated by the U function!

The difference between success and error is that they do not use U internally to generate the URL when it needs to be passed in.
