一.要点
1.选取图片
wx.chooseImage({ sizeType: [], // original 原图,compressed 压缩图,默认二者都有 sourceType: [], // album 从相册选图,camera 使用相机,默认二者都有 success: function (res) { console.log(res); var array = res.tempFilePaths, //图片的本地文件路径列表 }})
2.上传图片
wx.uploadFile({ url: ‘‘, //开发者服务器的 url filePath: ‘‘, // 要上传文件资源的路径 String类型!!! name: ‘uploadFile‘, // 文件对应的 key ,(后台接口规定的关于图片的请求参数) header: { ‘content-type‘: ‘multipart/form-data‘ }, // 设置请求的 header formData: { }, // HTTP 请求中其他额外的参数 success: function (res) { }, fail: function (res) { } }
二.代码示例
// 点击上传图片 upShopLogo: function () { var that = this; wx.showActionSheet({ itemList: [‘从相册中选择‘, ‘拍照‘], itemColor: "#f7982a", success: function (res) { if (!res.cancel) { if (res.tapIndex == 0) { that.chooseWxImageShop(‘album‘) } else if (res.tapIndex == 1) { that.chooseWxImageShop(‘camera‘) } } } }) }, chooseWxImageShop: function (type) { var that = this; wx.chooseImage({ sizeType: [‘original‘, ‘compressed‘], sourceType: [type], success: function (res) { /*上传单张 that.data.orderDetail.shopImage = res.tempFilePaths[0], that.upload_file(API_URL + ‘shop/shopIcon‘, res.tempFilePaths[0]) */ /*上传多张(遍历数组,一次传一张) for (var index in res.tempFilePaths) { that.upload_file(API_URL + ‘shop/shopImage‘, res.tempFilePaths[index]) } */ } }) }, upload_file: function (url, filePath) { var that = this; wx.uploadFile({ url: url, filePath: filePath, name: ‘uploadFile‘, header: { ‘content-type‘: ‘multipart/form-data‘ }, // 设置请求的 header formData: { ‘shopId‘: wx.getStorageSync(‘shopId‘) }, // HTTP 请求中其他额外的 form data success: function (res) { wx.showToast({ title: "图片修改成功", icon: ‘success‘, duration: 700 }) }, fail: function (res) { } }) },
