        },
        // 新增图片
        async afterRead(event) {
            let lists = [].concat(event.file);
            let fileListLen = this.scoreFileList.length;
            lists.map((item) => {
                this.scoreFileList.push({
                    ...item,
                    status: "uploading",
                    message: "上传中",

            for (let i = 0; i < lists.length; i++) {
                const result = await this.uploadFilePromise(lists[i].url);
                let item = this.scoreFileList[fileListLen];
                this.scoreFileList.splice(
                    fileListLen,
                    1,
                    Object.assign(item, {
                        status: "success",
                        message: "",
                        url: result,
                    })

                fileListLen++;
            }
        },
        uploadFilePromise(url) {
            return new Promise((resolve, reject) => {
                uni.uploadFile({
                    url: 'http://www.example.com/upload', // 仅为示例，非真实的接口地址
                    filePath: url,
                    name: "file",
                    success: (uploadFileRes) => {
                        let res = JSON.parse(uploadFileRes.data);
                        resolve(res.message);
                    },
                    fail: (err) => {
                        console.log(err);
                    },
                });
            });
        },

获取图片地址，数组形式

["4213.png", "6816.png"]

javascript 复制代码

 let detai_thumbs = this.scoreFileList.map((item) => item.url);
