Wi-Fi功能模块
App平台由 uni ext api 实现,需下载插件:uni-WiFi 链接:https://ext.dcloud.net.cn/plugin?id=10337
uni ext api 需 HBuilderX 3.6.8+
iOS平台获取Wi-Fi信息需要开启“Access WiFi information”能力登录苹果开发者网站,在“Certificates, Identifiers & Profiles”页面选择“Identifiers”中选择对应的App ID,确保开启“Access WiFi information”,保存后重新生成profile文件。
iOS平台iOS13及以上系统,获取当前连接的Wi-Fi信息需要先获取系统定位权限,因此在iOS13及以上系统使用此接口时,会触发定位权限申请的弹窗。
uni.startWifi(OBJECT)
