到目前为止，这是不可能的。您必须在<?php $string = 'I m Programmer'; $found="Prog"; if ( preg_match("~\b$found\b~",$string) ){ echo "Matched"; }else{ echo "No Match"; } ?> 中指定所有if ( preg_match("~\b".strtolower($found)."\b~",strtolower($string)) ){ echo "Matched"; }else{ echo "No Match"; } 。

对于其他人，您不需要显式指定cases，因为CodingKeys的原始类型为rawValue，并且会选择enum CodingKeys作为默认名称String，即

case

简短的答案是您无法做到。这只能通过将所有情况如下所示来完成：-

#{toasts}

将按原样选择键#include<vector> vector<int> my_vec; 和enum CodingKeys: String,CodingKey { case string_one,string_two case string_three = "string_three_%s" }

选中此形式的模态类。 希望您能找到解决方案

您必须设置所有编码键才能立即使用。

该类将仅对您在枚举CodingKeys中描述的键进行编码/解码。

如果您有更多的字符串，建议您与服务器团队联系以创建字符串数组（[String]）代替此模式。

更新：由于值的数量很多，因此您应该选择[String]

只是一个建议（未经测试），但是您可以将基类（扩展Codable）与不想覆盖的字段一起使用，然后使用仅包含您需要覆盖的名称的子类吗？即CodingKeys是否要求您为继承的字段定义值？
