微信开发 生成带参数二维码
在微信官方文档中的推广渠道中生成带参数的二维码,文档中写道
<code>用户扫描带场景值二维码时,可能推送以下两种事件: 如果用户还未关注公众号,则用户可以关注公众号,关注后微信会将带场景值关注事件推送给开发者。 如果用户已经关注公众号,在用户扫描后会自动进入会话,微信也会将带场景值扫描事件推送给开发者。 场景值是在生成二维码时 POST的数据中 详情见 http://mp.weixin.qq.com/wiki/index.php?title=%E7%94%9F%E6%88%90%E5%B8%A6%E5%8F%82%E6%95%B0%E7%9A%84%E4%BA%8C%E7%BB%B4%E7%A0%81 问 该场景值 是怎么个使用法? </code>

场景id,就是一个数字id,你可以调用数据库判断,
例如:你需要在全国各地分别放置一个场景二维码,假如你使用了区号作为场景id,当用户通过深圳扫描的场景二维码时,微信服务器就会返回755给你,你就知道这个新用户来自深圳这个场景。
比如,在每个页面放一个不同场景值的二维码,用来区分,用户在哪个页面上扫的人更多。
还有根据场景值可以对用户分组。后续可以对分组用户单独发特定消息。
其实很简单,场景值是在你自身系统中定义好的场景或者活动,用以区分不同的来源,比如一个二维码,需要使用在主站推广,或者是在某项特别的活动页面推广,调用不同的场景值,生成对应的二维码,后期就可以通过场景值进行关注来源的攻击使用了,使用方法比较灵活.
现在我每个用户需要一张唯一标示他的二维码 以便于我统计他们分享关注的人有好多,永久二维码只有100000张 ,临时二维码又有时间限制 请问我怎么办

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,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

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.
