短信跳转到小程序
短信跳转到小程序，实际上是网页跳转到小程序，发短信的时候内容带有链接，这个链接最好是短链接。 打开链接场景有三种情况：
- pc情况下，提示请用手机打开此链接；
- 非微信情况下打开，实际上采取了重定向，小程序要生成对应的Scheme，页面location.href = Scheme；
- 微信情况下打开，有两种方式，一种是采取跟非微信情况一样，另外一种采用h5的wx-open-launch-weapp标签。不同点是，方式1，如果在微信情况下打开会有一个弹出框二次确认，方法二点击跳转会直接跳往对应的小程序。
生成scheme注意事项：
- 单个小程序每日生成 Scheme 上限为50万个（包含短期有效 Scheme 与长期有效 Scheme）
- 有效时间超过31天的 Scheme 或永久有效的 Scheme 为长期有效Scheme，单个小程序总共可生成长期有效 Scheme 上限为10万个，请谨慎调用
- 有效时间不超过31天的 Scheme 为短期有效Scheme，单个小程序生成短期有效 Scheme 不设上限
