Node.js core.js:5873错误类型错误：无法读取属性'；文件名'；未定义的

node.js angular

Node.js core.js:5873错误类型错误：无法读取属性'；文件名'；未定义的,node.js,angular,httpclient,undefined,express-router,Node.js,Angular,Httpclient,Undefined,Express Router,我正在尝试在Node.JS服务器上存储一些图像，并使用以下代码从Angular客户端读取这些图像： image.ts： export class Image { fieldname: string; originalname: string; encoding: string; mimetype: string; destination: string; filename: string; path: string; size: n

我正在尝试在Node.JS服务器上存储一些图像，并使用以下代码从Angular客户端读取这些图像：

image.ts：

export class Image {
    fieldname: string;
    originalname: string;
    encoding: string;
    mimetype: string;
    destination: string;
    filename: string;
    path: string;
    size: number;
}

image.service.ts：

export class ImagesService {

  constructor(private http: HttpClient,
    private processHTTPMsgService: ProcessHTTPMsgService) { }

  getImages(): Observable<Image[]> {
    return this.http.get<Image[]>(baseURL + 'images')
      .pipe(catchError(this.processHTTPMsgService.handleError));
  }

}

imagesRouter.js：

imagesRouter.route('/')
.get(cors.cors, (req,res,next) => {
    Images.find({})
    .then((images) => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'application/json');
        res.json(images);

    }, (err) => next(err))
    .catch((err) => next(err));
})



module.exports = imagesRouter;

const express = require('express');
const bodyParser = require('body-parser');
const authenticate = require('../authenticate');
const multer = require('multer');
const cors = require('./cors');
const Images = require('../models/images');


const storage = multer.diskStorage({
    destination: (req, file, cb) => {
        cb(null, 'public/images');
    },

    filename: (req, file, cb) => {
        cb(null, file.originalname)
    }
});

const imageFileFilter = (req, file, cb) => {
    if(!file.originalname.match(/\.(jpg|jpeg|png|gif)$/)) {
        return cb(new Error('You can upload only image files!'), false);
    }
    cb(null, true);
};

const upload = multer({ storage: storage, fileFilter: imageFileFilter});

const uploadRouter = express.Router();
uploadRouter.use(bodyParser.json());

uploadRouter.route('/')

.post(cors.corsWithOptions, authenticate.verifyUser, authenticate.verifyAdmin, upload.single('imageFile'),
 (req, res, next) => {
    Images.create(req.file)
    .then((image) => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'application/json');
        res.json(req.file);
    }, (err) => next(err))
    .catch((err) => next(err));


})

以及uploadRouter.js：

imagesRouter.route('/')
.get(cors.cors, (req,res,next) => {
    Images.find({})
    .then((images) => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'application/json');
        res.json(images);

    }, (err) => next(err))
    .catch((err) => next(err));
})



module.exports = imagesRouter;

const express = require('express');
const bodyParser = require('body-parser');
const authenticate = require('../authenticate');
const multer = require('multer');
const cors = require('./cors');
const Images = require('../models/images');


const storage = multer.diskStorage({
    destination: (req, file, cb) => {
        cb(null, 'public/images');
    },

    filename: (req, file, cb) => {
        cb(null, file.originalname)
    }
});

const imageFileFilter = (req, file, cb) => {
    if(!file.originalname.match(/\.(jpg|jpeg|png|gif)$/)) {
        return cb(new Error('You can upload only image files!'), false);
    }
    cb(null, true);
};

const upload = multer({ storage: storage, fileFilter: imageFileFilter});

const uploadRouter = express.Router();
uploadRouter.use(bodyParser.json());

uploadRouter.route('/')

.post(cors.corsWithOptions, authenticate.verifyUser, authenticate.verifyAdmin, upload.single('imageFile'),
 (req, res, next) => {
    Images.create(req.file)
    .then((image) => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'application/json');
        res.json(req.file);
    }, (err) => next(err))
    .catch((err) => next(err));


})

我可以使用Postman成功上传图像，结果如下：

{
    "fieldname": "imageFile",
    "originalname": "home_header.jpg",
    "encoding": "7bit",
    "mimetype": "image/jpeg",
    "destination": "public/images",
    "filename": "home_header.jpg",
    "path": "public\\images\\home_header.jpg",
    "size": 58277
}

它将存储在MongoDB中，如下所示：

{
        "_id" : ObjectId("5e9051503af5a25cc487abe8"),
        "fieldname" : "imageFile",
        "originalname" : "home_header.jpg",
        "encoding" : "7bit",
        "mimetype" : "image/jpeg",
        "destination" : "public/images",
        "filename" : "home_header.jpg",
        "path" : "public\\images\\home_header.jpg",
        "size" : 58277,
        "createdAt" : ISODate("2020-04-10T10:58:24.710Z"),
        "updatedAt" : ISODate("2020-04-10T10:58:24.710Z"),
        "__v" : 0
}
{
        "_id" : ObjectId("5e90519c40aea44ca84df4ca"),
        "fieldname" : "imageFile",
        "originalname" : "logo.png",
        "encoding" : "7bit",
        "mimetype" : "image/png",
        "destination" : "public/images",
        "filename" : "logo.png",
        "path" : "public\\images\\logo.png",
        "size" : 18534,
        "createdAt" : ISODate("2020-04-10T10:59:40.979Z"),
        "updatedAt" : ISODate("2020-04-10T10:59:40.979Z"),
        "__v" : 0
}

但我不知道是什么问题，我无法在我的网站上看到图像并获得这些错误消息：
