一段时间后,我开始使用新的节点API,突然间,使用Postman'form-data'的数据测试停止了工作。数据以状态码200存储到数据库中,但请求正文(标题和类别)显示为空。我尝试使用原始主体,但效果很好,但还需要使用表单数据在主体中发送文件。
这是我的 app.js 代码段:
app.use(morgan('dev'));
app.use(bodyParser.json());
app.use((req, res, next) => {
res.header('Access-Control-Allow-Origin', '*');
res.setHeader(
'Access-Control-Allow-Headers',
'Origin, X-Requested-With, Content-Type, application/json, Accept, Authorization'
);
if(req.method === 'OPTIONS') {
res.header('Access-Control-Allow-Methods', 'PUT, POST, GET, DELETE, PATCH');
return res.status(200).json();
}
next();
});
app.use('/articles', articleRoutes);
app.use((req, res, next) => {
const error = new Error('Not found');
error.status = 404;
next(error);
});
型号:
const mongoose = require('mongoose');
const articleSchema = mongoose.Schema({
_id: mongoose.Schema.Types.ObjectId,
title: String,
category: String,
date: {type: Date, default: Date.now},
})
module.exports = mongoose.model('article', articleSchema);
Articleroute.js
const express = require('express');
const router = express.Router();
const articleController = require('../controllers/articles');
router.get('/', articleController.article_get_all);
router.post('/', articleController.article_create);
module.exports = router;
article_create
exports.article_create = (req, res, next) => {
const body = req.body;
body._id = mongoose.Types.ObjectId();
const article = new Article(body);
article
.save()
.then(docs => {
console.log(docs, 'article');
res.status(200).json(docs);
})
.catch(err => {
console.log(err);
res.status(500).json({
error: err
});
});
};
我尝试重新安装body-parser模块,但都没有用。
这是使用表单数据的邮递员结果:
{
"_id": "5c76d1c01c20fa064cbcbaf1",
"date": "2019-02-27T18:06:56.287Z",
"__v": 0
}
