我正在使用 React , mongoose , node , express , multer . 我想在博客内容中添加任意数量的段落或图片。我完全迷路了，我不知道该如何定义模式并将它们保存到数据库中。而且，我使用 multer.any() 作为中间件。我不太确定是否 multer 将影响非图像数据
现在让我试着只上传一个图片和一个段落，我使用console.log检查结果。

const BlogSchema = new mongoose.Schema({
    title: {
        type: String,
    },
    coverImage: {
        type: String,
    },
    blogImage: {
        type: String,
    },
    lastModified: {
        type: String,
    },
    category: {
        type: String,
    },
    blogContent: {
        type: Schema.Types.Mixed, // this is the content where I can insert images and paragraphs
    }
})

路线

const upload = multer({
    storage: multer.memoryStorage(),
    limits: {
        fileSize: 5 * 1024 * 1024,
    },
});

router.patch(/:id, upload.any(), (req, res, next) => {
  console.log(req.body.blogContent);    // Output --> [object Object],[object, Object]
  console.log(req.files);   // Output --> []
})

server.js

require("dotenv").config({path: "./config.env"});
const express = require("express");
const connectDB = require('./config/db');

const app = express();

// Connect DB
connectDB();

// express middleware
app.use(express.json());
app.use('/blog', require('./routes/blogPage'));
app.use(express.urlencoded({ extended: false }));

const PORT = process.env.PORT || 5000;
const server = app.listen(PORT, () => console.log(`Server running on port ${PORT}`))

// handle error
process.on("unhandledRejection", (err, promise) => {
    console.log(`Logged Error: ${err}` )
    server.close(() => process.exit(1))
})

我从中得到一个奇怪的输出 req.body.blogContent 并且没有从中获得任何输出 req.files 即使它应该在那里。我真的需要帮助！
