对小程序的一些原生api进行封装

我们在开发原生小程序时,对微信提供的api总需要占位置且重复度极高,这边我整理了一下常用的api进行封装

export default class wxapi {

    /*

    *微信小程序API类

    */

    // 加载

    showLoading(

        title = '加载中...',

        mask = true

    ) {

        wx.showLoading({

            title,

            mask

        })

    }

    // 提示

    showToast(

        title,

        icon = 'none',

        sucFn = () => {

        },

        duration = 2000,

        mask = true

    ) {

        wx.showToast({

            title,

            icon,

            duration,

            mask,

            success: () => {

                return setTimeout(sucFn, duration)

            }

        })

    }

    // 弹窗

    showModal(

        content,

        sucFn = () => {

        },

        title = '提示',

        showCancel = true,

        confirmText = '确定',

        cancelText = '取消'

    ) {wx.showModal({

            title,

            content,

            confirmText,

            cancelText,

            showCancel,

            success: res => {

                return sucFn(res)

            }

        })

    }

    // 操作菜单

    showActionSheet(

        itemList,

        sucFn = () => {

        },

    ) {

        wx.showActionSheet({

            itemList,

            success: res => {

                return sucFn(res.tapIndex)

            }

        })

    }

    // 路由

    navTo(url, isSub = false) {

        wx.navigateTo({

            url: isSub ? `/subPackage/pages/${url}` : `/pages/${url}` 

        })

    }

    redTo(url, isSub = false) {

        wx.redirectTo({

            url: isSub ? `/subPackage/pages/${url}` : `/pages/${url}`

        })

    }

    tabTo(url) {

        wx.switchTab({

            url: isSub ? `/subPackage/pages/${url}` : `/pages/${url}`

        })

    }

    relTo(url, isSub = false) {

        wx.relaunch({

            url: isSub ? `/subPackage/pages/${url}` : `/pages/${url}`

        })

    }

    navBack(

        delta = 1,

        sucFn = () => {

        },

    ) {

        wx.navigateBack({

            delta,

            success: () => {

                return sucFn

            }

        })

    }

    // 登录

    login() {

        return new Promise(resolve => {

            wx.login({

                success: res => {

                    resolve(res.code)

                }

            })

        })

    }

    // 上传文件

    uploadFile(url, filePath, name, formData = {}) {

        return new Promise(resolve => {

            wx.uploadFile({

                url: config.apiBaseUrl + url,

                filePath,

                header: {

                    'content-type': 'application/x-www-form-urlencoded',

                    'appid': config.appid,

                    'Authorization': userUtil.getKey('token')

                },

                formData,

                success: res => {

                    resolve(res.data)

                },

                fail: () => {

                    resolve('')

                }

            })

        })

    }

    // 选择图片

    chooseImage(count) {

        return new Promise(resolve => {

            wx.chooseImage({

                count,

                success: res => {

                },

                fail: () => {

                    resolve('')

                }

            })

        })

    }

    // 授权

    getSetting() {

        return new Promise(resolve => {

            wx.getSetting({

                    resolve(res.authSetting)

                }

                success: res => {

                    resolve(res.authSetting)

                }

            })

        })

    }

    // 收货地址

    chooseAddress() {

        return new Promise(resolve => {

            wx.chooseAddress({

                success: res => {

                    resolve(res)

                }

            })

        })

    }

    // 设置标题

    setTitle(title) {

        wx.setNavigationBarTitle({

            title

        })

    }

    // 获取图片信息

    getImageInfo(src) {

        return new Promise(resolve => {

            wx.getImageInfo({

                src,

                success: res => {

                    console.log(res)

                    resolve(res)

                },

                fail: () => {

                    resolve('')

                }

            })

        })

    }

    // 获取某项授权

    async getSomeSetting(setting, doSomething, callback) {

        // 获取授权信息

        const auth = await this.getSetting();

        if (auth) {

            if (Object.keys(auth).indexOf(setting.type) === -1 || auth[setting.type]) {

                return doSomething()

            } else if (!auth[setting.type]) {

                this.showModal(`你已拒绝${setting.name}授权,请按确定前往新页面选中"${setting.name}"重新授权`, res => {

    }

    hideTabBar(animation = true) {

}



使用时直接引用 例如:

import wxapi from './utils/wxapi';

wxapi: new wxapi(), //常用的微信接口封装

app.wxapi.showLoading('加载中~');
