【问题描述】：

大家好，我是新手，节点，我希望在创建帖子时传递文本和类别值（架构中的 catg）。

我能够传递文本并创建帖子，但我还想在创建帖子时添加一个类别

这是创建帖子的路径

router.post('/', [auth, [
        check('text', 'text is required').not().isEmpty()

    ]],

    async(req, res) => 

        const errors = validationResult(req);
        if (!errors.isEmpty()) 
            return res.status(400).json( errors: errors.array() );
        
        try 
            const user = await User.findById(req.user.id).select('-password'); //don't want to send password back
            const newPost = new Post(
                text: req.body.text,
                name: user.name,
                avatar: user.avatar,
                user: req.user.id,
                //catg:req.
            )
            const post = await newPost.save();
            res.json(post);

         catch (err) 
            console.log(err.message);
            res.status(500).send('Server Error');

        

    );

这是添加帖子的操作

export const addPost = formData => async dispatch => 
  const config = 
    headers: 
      'Content-Type': 'application/json'
    
  ;

  try 
    const res = await axios.post('/api/posts', formData, config);

    dispatch(
      type: ADD_POST,
      payload: res.data
    );

    dispatch(setAlert('Post Created', 'success'));
   catch (err) 
    dispatch(
      type: POST_ERROR,
      payload:  msg: err.response.statusText, status: err.response.status 
    );
  
;

这是帖子架构：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

// Create Schema
const PostSchema = new Schema(
  user: 
    type: Schema.Types.ObjectId,
    ref: 'users'
  ,
  text: 
    type: String,
    required: true
  ,
  name: 
    type: String
  ,
  avatar: 
    type: String
  ,
  isApproved: 
    type: Boolean,
    default: false
  ,
  catg: 
    type: String,
    default: '0'
  ,
  likes: [
    
      user: 
        type: Schema.Types.ObjectId,
        ref: 'users'
      
    
  ],
  comments: [
    
      user: 
        type: Schema.Types.ObjectId,
        ref: 'users'
      ,
      text: 
        type: String,
        required: true
      ,
      name: 
        type: String
      ,
      avatar: 
        type: String
      ,
      date: 
        type: Date,
        default: Date.now
      
    
  ],
  date: 
    type: Date,
    default: Date.now
  
);

module.exports = Post = mongoose.model('post', PostSchema);

【参考方案1】：

大家好，这很简单，我只需在创建帖子时添加类别的值，它就可以工作

 onSubmit=e => 
      e.preventDefault();
      addPost( text,value );
      setText('');
    

谢谢大家
