HomeBackend DevelopmentPHP Tutorial基于JSON类型返回的API接口如果做输出校验?

现在在开发一个api接口,返回数据是json格式的,前端输入有validator校验器可以校验数据是否合法,那后台输出的返回呢?只能用phpunit的单元测试方法测试字段是否完全返回吗?有没有什么比较简单的输出校验框架可以用

后台写一个验证类吧。

给你一个做参考

<code><?php /**
 * 验证类
 * 
 * @package
 */
Class Validate{
    /**
     * 存放验证信息
     *
     * @var array
     */
    public $validateparam = array();
    /**
     * 验证规则
     *
     * @var array
     */
    private $validator = array(
        "email"=>'/^([.a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(\\.[a-zA-Z0-9_-])+/',
        "phone"=>'/^(([0-9]{2,3})|([0-9]{3}-))?((0[0-9]{2,3})|0[0-9]{2,3}-)?[1-9][0-9]{6,7}(-[0-9]{1,4})?$/',
        "mobile"=>'/^1[0-9]{10}$/',
        "url"=>'/^http:(\\/){2}[A-Za-z0-9]+.[A-Za-z0-9]+[\\/=?%-&_~`@\\[\\]\':+!]*([^\"\"])*$/',
        "currency"=>'/^[0-9]+(\\.[0-9]+)?$/',
        "number"=>'/^[0-9]+$/',
        "zip"=>'/^[0-9][0-9]{5}$/',
        "qq"=>'/^[1-9][0-9]{4,8}$/',
        "integer"=>'/^[-+]?[0-9]+$/',
        "integerpositive"=>'/^[+]?[0-9]+$/',
        "double"=>'/^[-+]?[0-9]+(\\.[0-9]+)?$/',
        "doublepositive"=>'/^[+]?[0-9]+(\\.[0-9]+)?$/',
        "english"=>'/^[A-Za-z]+$/',
        "chinese"=>'/^[\x80-\xff]+$/',
        "username"=>'/^[\\w]{3,}$/',
        "nochinese"=>'/^[A-Za-z0-9_-]+$/',
    );

    /**
     * 验证数组中的值
     *
     * <code>
     * //使用示例
     * <?php *  require("commonvalidate.class.php");
     *    $a = new CommonValidate();

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
