iweb • 2021年5月9日 pm10:33 • 前端 • 阅读 88

注

微信中打开网页，可跳转微信小程序操作。

前期准备

  1. 目前仅支持在微信内打开H5页面；
  2. 已认证的服务号，服务号绑定“JS接口安全域名”下的网页可使用此标签跳转任意合法合规的小程序；
  3. 已认证的非个人主体的小程序，使用小程序云开发的静态网页托管绑定的域名下的网页，可以使用此标签跳转任意合法合规的小程序。

绑定安全域名：

登录微信公众平台进入【公众号设置】–>【功能设置】里设置好 “js接口安全域名”。

IP白名单设置：

登录微信公众平台进入【开发】–>【基本配置】，这里填写你服务器的IP。
