一、引入七牛SDK
具体查看文档
https://github.com/gpake/qiniu-wxapp-sdk/blob/master/README.md
二、封装上传方法upload.js
/** * 上传函数 */ const qiniuUploader = require("qiniuUploader"); const request = require("./request.js") // 初始化七牛相关参数 function initQiniu() { var options = { uploadURL: 'https://up.qiniup.com', region: 'ECN', // uptokenURL: request.URL + 'qiniu-token?token=' + getApp().globalData.token, // uptoken: 'xxxx', domain: 'cdn-mpsoft.tujihome.com/', }; qiniuUploader.init(options); } function upload(filePath, success, fail) { initQiniu(); // 交给七牛上传 qiniuUploader.upload(filePath, (res) => { success(res); }, (error) => { console.error('error: ' + JSON.stringify(error)); fail(error); }); } /** * 批量上传 * @param images */ function batchUpload(images) { let uplist = [] for (let index in images) { const path = images[index]['url']; const key = images[index]['key']; let promise = new Promise((resolve, reject) => { qiniuUploader.upload(path, (res) => { resolve(res.imageURL) }, (error) => { reject(error) },{ uploadURL: 'https://up.qiniup.com', region: 'ECN', // uptokenURL: request.URL + 'qiniu-token?token=' + getApp().globalData.token, key: key, domain: 'cdn-mpsoft.tujihome.com/', }); }) uplist.push(promise) } Promise.all(uplist).then((resultList) => { console.log(resultList); return resultList; }, error => { console.log(error) throw err; }) } module.exports = { 'upload': upload, 'BatchUpload' : batchUpload, }
url:文件路径,key:文件名
batchUpload()传入数组,包含文件路径跟文件名,不需要自定义文件名可以修改下,只调用一次初始化方法,
返回值为包含所有文件路径的数组
三、调用
uploadImage(images) { var that = this var imageURL = []; for (var i of images) { i.key = 'gclw_' + Date.parse(new Date()) + Math.random() + '.jpg'; } try { imageURL = upload.BatchUpload(images); return imageURL; } catch (e) { wx.showModal({ title: '提示', content: e, showCancel: false, }) } },
结果
