个人最近在微信小程序开发时，写的一个通用的权限接口信息获取方法，在uni-app环境下测试通过，希望能帮助到大家！
使用方法：函数参数interfaceName指的是小程序的接口名称，如
wx.getLocation,interfaceName指的就是getLocation，当获取权限成功时通过Promise resolve(res)返回，res为对应接口的返回值（获取值可能存在失败情况，需要自己判断），而无权获取信息时通过Promise reject(r)返回，可以做后续页面显示。
function getInterfaceInfo(interfaceName) { const authorizationMap = { 'getUserInfo': 'scope.userInfo', 'getLocation': 'scope.userLocation', 'chooseLocation': 'scope.userLocation', 'chooseAddress': 'scope.address', 'chooseInvoiceTitle': 'scope.invoiceTitle', 'chooseInvoice': 'scope.invoice', 'getWeRunData': 'scope.werun', 'startRecord': 'scope.record', 'saveImageToPhotosAlbum': 'scope.writePhotosAlbum', 'saveVideoToPhotosAlbum': 'scope.writePhotosAlbum', 'camera': 'scope.camera' } return new Promise((resolve, reject) => { const scopeName = authorizationMap[interfaceName] uni.getSetting({ success: (res) => { console.log(`get user ${scopeName} setting:`, res) if (scopeName in res.authSetting) { // 判断用户是否已经有权限 if (res.authSetting[scopeName]) { console.log('authorize result:', res) uni[interfaceName]({ success: (res) => { console.log('get user setting data success:', res) resolve(res) }, fail: (r) => { console.log('get user setting data fail:', res) resolve(r) } }) } else { reject(res) } } else { uni.authorize({ scope: scopeName, success: (res) => { console.log('authorize result:', res) uni[interfaceName]({ success: (res) => { console.log('get user setting data success:', res) resolve(res) }, fail: (r) => { console.log('get user setting data fail:', res) resolve(r) } }) }, fail: (r) => { console.log('fail:', r) reject(r) } }) } }, fail: (r) => { reject(r) } }) })} |
调用getInterfaceInfo后，怎么用返回的值给页面的data赋值呢
回调函数会返回接口值，你再使用setData设置数据就行。
