            for (let i = 0; i < res.data.result.length; i++) {
                        let result = res.data.result[i];

                            let imgUrl = that.mixinBaseUrl + '/file' + result.url
                            // 创建对象
                            let img = new Image()
                            // 改变图片的src
                            img.src = imgUrl
                            // 定时执行获取宽高
                            let check = function () {
                                // 只要任何一方大于0
                                // 表示已经服务器已经返回宽高
                                if (img.width > 0 || img.height > 0) {
                                    that.picitems.push({
                                        src: that.mixinBaseUrl + '/file' + result.url,
                                        thumbnail: that.mixinBaseUrl + '/file' + result.url,
                                        w: img.width,

                                    console.log(img.width, img.height)
                                    clearInterval(set)
                                    img = null

                                }
                            }
                            let set = setInterval(check, 40)
                        })(i)
                    }
