uniapp获取当前位置及检测授权定位权限

效果图

Android设备

• 点击 “设置”，跳转应用信息，打开“权限即可”；

创建js文件

permission.js

• 新建 .js 文件，例： permission.js
• 管理相关权限，例相册、相机等，可以写在此文件中
• 根据不同平台，处理向系统请求权限

/// null = 未请求，1 = 已允许，0 = 拒绝|受限, 2 = 系统未开启

• 检测当前权限
• 获取当前位置
• 拒绝授权，弹窗提示
• 跳转App应用设置，打开位置权限

const location = {

使用

<button type="primary" @click="getLocation">获取位置</button>

import location from '@/common/js/location.js'

/**
 * 获取位置
 */
getLocation() {
    location.getLocation();
}

• 回调

location.getLocation((res) => {
    if (res != 1) return;

    // xxx
});
