快速删除请求甚至不处理请求正文

问题描述

我正在使用 node.js、express 和 mongodb 开发 api 我有一个路由 DELETE HTTP:localhost:5000/api/users/usernames/ 我发送 包含用户名的 json 对象

我正在使用 Insomnia 提出请求。

server.js

require('dotenv').config();
const express = require('express');
const cors = require('cors');
const mongoose = require('mongoose');
const errorHandler = require('./_helpers/error-handler');



const app = express();

const port = process.env.PORT || 5000;


app.use(cors());
app.use(express.json());


const uri = process.env.ATLAS_URI;
mongoose.connect(uri,{ useNewUrlParser: true,useCreateIndex: true,useUnifiedTopology: true});
const connection = mongoose.connection;
connection.once('open',() => {
    console.log("MongoDB database connection established successfully");
});

// routers
app.use('/api/users',require('./routes/api/users/users.controller'));

app.use(errorHandler);

app.listen(port,() => {
    console.log(`Server is running on port ${port}`);
});

user.model.js

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const Roles = require('../_helpers/roles');

const User = new Schema({
    username: { type: String,unique: true,required: true },hash: { type: String,firstName: { type: String,lastName: { type: String,role: { type: String,enum: Object.keys(Roles),createdDate: { type: Date,default: new Date() }
});

User.set('toJSON',{
    virtuals: true,versionKey: false,transform: function (doc,ret) {
        delete ret._id;
        delete ret.hash;
    }
});

module.exports = mongoose.model('User',User);

这是我的 userController js 文件

router.delete('/usernames',authorize(Roles.Admin),_deleteByUsername);

function _deleteByUsername(req,res,next) {
    userService.deleteByUsername(req.body)
        .then(() => res.status(200).json({"message": "User(s) successfully deleted!"}))
        .catch(err => next(err));
}

这是我的 userService js 文件

function _deleteByUsername(usernames) {
    Object.values(usernames).forEach(async (username) => {
        await User.findOneAndDelete({username})
    });
}

当我删除 HTTP://localhost:5000/api/users/usernames 时 使用这个 json 对象

{
    "0": "testUser1","1": "testUser2
}

它似乎甚至没有通过 _deleteByUsername 中的 req.body 这是我得到的错误

}

我不知道我做错了什么。我希望请求正文是 json 对象，所以我可以使用 Object.values() 但问题是我认为它甚至不会调用 _deleteByUsername
