PHP实现微信网页授权开发教程_php实例
微信网页授权是服务号才有的高级功能,开发者可以通过授权后获取用户的基本信息;在此之前,想要获取消息信息只能在用户和公众号交互时根据openid获取用户信息;而微信网页授权可在不需要消息交互,也不需要关注的情况下获取用户的基本信息。
微信网页授权时通过OAuth2.0完成的,整个过程分为三步:
- 用户授权,获取code;
- 根据code获取access_token【可通过refresh_token刷新获取较长有效期】
- 通过access_token和openid获取用户信息
对微信网页授权过程做了简单封装:
<?php /** * 微信授权相关接口 */ class Wechat { //高级功能-》开发者模式-》获取 private $app_id = 'xxx'; private $app_secret = 'xxxxxxx'; /** * 获取微信授权链接 * * @param string $redirect_uri 跳转地址 * @param mixed $state 参数 */ public function get_authorize_url($redirect_uri = '', $state = '') { $redirect_uri = urlencode($redirect_uri); return "https://open.weixin.qq.com/connect/oauth2/authorize?appid={$this->app_id}&redirect_uri={$redirect_uri}&response_type=code&scope=snsapi_userinfo&state={$state}#wechat_redirect"; } /** * 获取授权token * * @param string $code 通过get_authorize_url获取到的code */ public function get_access_token($app_id = '', $app_secret = '', $code = '') { $token_url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid={$this->app_id}&secret={$this->app_secret}&code={$code}&grant_type=authorization_code"; $token_data = $this->http($token_url); if($token_data[0] == 200) { return json_decode($token_data[1], TRUE); } return FALSE; } /** * 获取授权后的微信用户信息 * * @param string $access_token * @param string $open_id */ public function get_user_info($access_token = '', $open_id = '') { if($access_token && $open_id) { $info_url = "https://api.weixin.qq.com/sns/userinfo?access_token={$access_token}&openid={$open_id}&lang=zh_CN"; $info_data = $this->http($info_url); if($info_data[0] == 200) { return json_decode($info_data[1], TRUE); } } return FALSE; } public function http($url, $method, $postfields = null, $headers = array(), $debug = false) { $ci = curl_init(); /* Curl settings */ curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($ci, CURLOPT_TIMEOUT, 30); curl_setopt($ci, CURLOPT_RETURNTRANSFER, true); switch ($method) { case 'POST': curl_setopt($ci, CURLOPT_POST, true); if (!empty($postfields)) { curl_setopt($ci, CURLOPT_POSTFIELDS, $postfields); $this->postdata = $postfields; } break; } curl_setopt($ci, CURLOPT_URL, $url); curl_setopt($ci, CURLOPT_HTTPHEADER, $headers); curl_setopt($ci, CURLINFO_HEADER_OUT, true); $response = curl_exec($ci); $http_code = curl_getinfo($ci, CURLINFO_HTTP_CODE); if ($debug) { echo "=====post data======\r\n"; var_dump($postfields); echo '=====info=====' . "\r\n"; print_r(curl_getinfo($ci)); echo '=====$response=====' . "\r\n"; print_r($response); } curl_close($ci); return array($http_code, $response); } }

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,

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

In PHP, you can effectively prevent CSRF attacks by using unpredictable tokens. Specific methods include: 1. Generate and embed CSRF tokens in the form; 2. Verify the validity of the token when processing the request.

H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.

Strict types in PHP are enabled by adding declare(strict_types=1); at the top of the file. 1) It forces type checking of function parameters and return values to prevent implicit type conversion. 2) Using strict types can improve the reliability and predictability of the code, reduce bugs, and improve maintainability and readability.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

In PHP, the final keyword is used to prevent classes from being inherited and methods being overwritten. 1) When marking the class as final, the class cannot be inherited. 2) When marking the method as final, the method cannot be rewritten by the subclass. Using final keywords ensures the stability and security of your code.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
