uni-app 选择图片上传到服务器、云储存

1、选择图片到node服务器

uni-app代码

uni.chooseImage({
    success: (res) => {
        let tempFilePaths = res.tempFilePaths;
        tempFilePaths.forEach((item) => {
            uni.uploadFile({
                url: '', //服务器地址
                fileType: "image", //ZFB必填,不然报错
                filePath: item, //这个就是我们上面拍照返回或者先中照片返回的数组
                name: 'file',
                success: (uploadFileRes) => {
});

node服务代码

const path = require("path"); //导入path模块
const multer = require("multer"); //导入multer模块
const fs = require("fs"); //导入文件操作模块
const util = require("../public/util");
const upload = multer({ dest: "tmp/" });
let express = require("express");
let router = express.Router();
router.post("/upload", upload.single("file"), function (req, res) {
  let imgFile = req.file; //获取图片上传的资源
  var tmp = imgFile.path; //获取临时资源
  let ext = path.extname(imgFile.originalname); //利用path模块获取 用户上传图片的 后缀名
  let newName =util.getNowFormatDate('-','-')+ "-"+new Date().getTime() + Math.round(Math.random() * 10000) + ext; //给用户上传的图片重新命名 防止重名
  let newPath = "/public/images/" + newName; //给图片设置存放目录  提前给当前文件夹下建立一个   images文件夹  ！！！！
  let fileData = fs.readFileSync(tmp); //将上传到服务器上的临时资源 读取到 一个变量里面
  let filePath = path.join(__dirname, '..'+newPath);
  fs.writeFileSync(filePath, fileData); //重新书写图片文件  写入到指定的文件夹下
  res.send(newPath); //上传成功之后  给客户端响应
router.get('/public/images/*', function (req, res) {
    let newPath = ".."+req.url;
    let filePath = path.join(__dirname,newPath);
    res.sendFile(filePath);
module.exports = router;

2、选择图片到云储存

uni.chooseImage({
    success: (res) => {
        let tempFilePaths = res.tempFilePaths;
        tempFilePaths.forEach((item) => {
           uniCloud.uploadFile({
                filePath: item,
                cloudPath: 'item.jpg',
                success(res) {
                fail(res) {
