+## 使用文档
+
+```ts
+
+import { getCurrentWifiInfo, requestLocationPromise } from '@/uni_modules/uni-wifiinformation';
+
+// 获取系统定位权限
+requestLocationPromise(function(res){
+	console.log(res)
+	uni.showToast({
+		title: res["message"],
+		icon: 'none'
+	})
+})
+
+// 获取手机当前连接的wifi信息
+getCurrentWifiInfo({
+	success:function(res){
+		console.log(res)
+		uni.showToast({
+			title: `当前wifi信息: interface: ${res.wifiInterface}, SSID: ${res.SSID}, BSSID: ${res.BSSID}` ,
+			icon: 'none'
+		})
+	}
+})
+
+// 注意：iOS12之后获取wifi信息需要获取系统定位权限，否则获取到的wifi信息为空
+// 所以建议在获取wifi信息之前，先调用获取系统定位权限的接口
+// 示例如下：
+requestLocationPromise(function(res) {
+	if (res["success"] == true) {
+		getCurrentWifiInfo({
+			success:function(res){
+				console.log(res)
+				uni.showToast({
+					title: `当前wifi信息: interface: ${res.wifiInterface}, SSID: ${res.SSID}, BSSID: ${res.BSSID}` ,
+					icon: 'none'
+				})
+			}
+		})
+	}
+})
+
