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

问 该场景值  是怎么个使用法?

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

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
