启用Csrf后POST数据时出现的400错误_PHP
最近一直出现这样的错误,一直在查找原因,偶然看到一篇解决的文章,分享给大家看看。
第一种解决办法是关闭Csrf
public function init(){ $this->enableCsrfValidation = false; }
第二种解决办法是在form表单中加入隐藏域
第三种解决办法是在AJAX中加入_csrf字段
var csrfToken = $('meta[name="csrf-token"]').attr("content"); $.ajax({ type: 'POST', url: url, data: {_csrf:csrfToken}, success: success, dataType: dataType });
Yii这个匹配的过程和Yii::$app->request->csrfToken 这个值存储位置说明:
存储位置
protected function createCsrfCookie($token) { $options = $this->csrfCookie; $options['name'] = $this->csrfParam; $options['value'] = $token; return new Cookie($options); }
校验方法
public function validateCsrfToken($token = null) { $method = $this->getMethod(); // only validate CSRF token on non-"safe" methods http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.1.1 if (!$this->enableCsrfValidation || in_array($method, ['GET', 'HEAD', 'OPTIONS'], true)) { return true; } $trueToken = $this->loadCsrfToken(); if ($token !== null) { return $this->validateCsrfTokenInternal($token, $trueToken); } else { return $this->validateCsrfTokenInternal($this->getBodyParam($this->csrfParam), $trueToken) || $this->validateCsrfTokenInternal($this->getCsrfTokenFromHeader(), $trueToken); } }
以上所述就是本文的全部内容了,希望大家能够喜欢。

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,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
