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(); * $a->setValidate("344d",true,"","不可以为空"); * $a->setValidate("fdsfsfd",true,"Email","请填写正确的EMAIL"); * echo $a->validate(); * * //显示结果: * 请填写正确的EMAIL * ? > * </code> * * @param * @return string 字符串类型的返回结果 */ public function validate(){ if (!is_array($this->validateparam)){ return false; } foreach($this->validateparam as $k=>$v){ $v['validator'] = strtolower($v['validator']); if ($v['require'] == ""){ $v['require'] = false; } if ($v['input'] == "" && $v['require'] == "true"){ $this->validateparam[$k]['result'] = false; }else{ $this->validateparam[$k]['result'] = true; } if ($this->validateparam[$k]['result'] && $v['input'] != ""){ switch($v['validator']){ case "custom": $this->validateparam[$k]['result'] = $this->check($v['input'],$v['regexp']); break; case "compare": if ($v['operator'] != ""){ eval("\$result = '" . $v['input'] .

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
