注意参数获取方式业务场景较多的小程序码，使用getwxacodeunlimit获取，其参数需要注意，可不是?id=2，扫码访问内容页面，在页面的onload方法中，解析小程序码的参数比如要传入一个用户id=12，scene参数就可以写成"12"，多个参数按一定规则分开，如 符号，面的onload生命周期中处理参数onLoad:function(options){ if(options.scene){ let scene=decodeURIComponent(options.scene); // 是我们定义的参数链接方式 let id=scene.split(" ")[0]; let shop_id=scene.split(' ')[1]; //其他逻辑处理。。。。。场景id官方文档要求格式为:
