图片上传服务器：
wxml
<view class="container"> <button bindtap='chooseImageTap'>上传图片</button></view>wxss
Page({ /** * 页面的初始数据 */ data: { imgs: [],//本地图片地址数组 picPaths:[],//网络路径 }, /** * 生命周期函数--监听页面加载 */ onLoad: function (options) { }, //添加上传图片 chooseImageTap: function () { var that = this; wx.showActionSheet({ itemList: ['从相册中选择', '拍照'], itemColor: "#00000", success: function (res) { if (!res.cancel) { if (res.tapIndex == 0) { that.chooseWxImage('album') } else if (res.tapIndex == 1) { that.chooseWxImage('camera') } } } }) }, // 图片本地路径 chooseWxImage: function (type) { var that = this; var imgsPaths = that.data.imgs; wx.chooseImage({ sizeType: ['original', 'compressed'], sourceType: [type], success: function (res) { console.log(res.tempFilePaths[0]); that.upImgs(res.tempFilePaths[0], 0) //调用上传方法 } }) }, //上传服务器 upImgs: function (imgurl, index) { var that = this; wx.uploadFile({ url: 'https://xxxxxxxxxxxxxxxxxxxxxxxxxxxx',// filePath: imgurl, name: 'file', header: { 'content-type': 'multipart/form-data' }, formData: null, success: function (res) { console.log(res) //接口返回网络路径 var data = JSON.parse(res.data) that.data.picPaths.push(data['msg']) that.setData({ picPaths: that.data.picPaths }) console.log(that.data.picPaths) } }) },})思路很简单,多张上传的话，在 upImgs 方法回调做判断 index++ 继续调用 upImgs方法即可
