将带有文本内容的表单数据从vuejs前端发送到Nodejs服务器，但是文件从未上传到服务器。我已经有一段时间了。这是我详细的前端和后端代码：
前端
//Front end VueJS
上传表单组件
<template>
<div class="container">
<form v-on:submit.prevent="addMember" method="post">
<div class="row">
<div class="col-sm-10 col-md-10 col-lg-10">
<div class="form-group">
<label>Title<span class="required-field">*</span>:</label>
<input type="text" class="form-control" v-model="member.title" name="title" v-validate="'required|min:10'">
<div class="help-block alert alert-danger" v-show="errors.has('title')">
{{errors.first('title')}}
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-sm-10 col-md-10 col-lg-10">
<div class="form-group">
<label>Full Name<span class="required-field">*</span>:</label>
<input type="text" class="form-control" v-model="member.fullname" name="fullname" v-validate="'required|min:10'">
<div class="help-block alert alert-danger" v-show="errors.has('fullname')">
{{errors.first('fullname')}}
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-sm-10 col-md-10 col-lg-10">
<div class="form-group">
<label>Passport Photo
<input type="file" id="file" ref="photo" v-on:change="handleFileUpload()"/>
</label>
</div>
</div>
</div>
</form>
<div class="row">
<div class="col-sm-10 col-md-10 col-lg-10">
<div class="form-group">
<button class="btn btn-info btn-lg pull-right">Save</button>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
name:'CreateMember',
data(){
return{
member:{},
photo:'',
}
},
},
methods: {
handleFileUpload(){
this.coverimage = this.$refs.photo.files[0]
},
addMember(){
this.$validator.validateAll().then(()=>
{
let formData = new FormData();
formData.append('file', this.photo);
let rawData = this.member
rawData = JSON.stringify(rawData)
formData.append('data',rawData)
this.axios.post('/members',this.member,{
'content-type':'multipart/form-data'
}).then((resp)=>{
console.log(resp.data)
//this.$router.push({name: 'members'})
}).catch((error)=>{
console.log(error)
})
});
}
}
}
</script>
后端（Nodejs和Express）
**routes/members.js**
var express = require('express');
var router = express.Router();
//Require Controller Modules
var controller = require('../controllers/MembersController');
var auth = require('../middleware/auth');
const path = require('path');
const multer = require('multer');
//Define file storage engine
const storage = multer.diskStorage({
destination:'public/uploads/',
filename: (req,file,cb)=>{
cb(null,file.fieldname+'-'+Date.now()+path.extname(file.originalname));
}
});
//Filter uploaded file and only upload file types of enumerated format
const fileTypeFilter = (req, file, cb)=>{
if(file.mimetype==='image/jpeg'||file.mimetype==='image/jpg'|| file.mimetype==='image/png'){
cb(null, true);
}
else{
cb(new error('Invalid Image Format'), false);
}
}
const upload = multer({storage:storage,
limits:
{
fileSize:1024*1024*1000
},
filefilter:fileTypeFilter
});
//Save new member to the database
router.post('/members', upload.single('photo'),auth,controller.createMember);
Controllers/MembersController.js
var express = require('express');
var router = express.Router();
const fs = require('fs');
const Model = require('../models/index');
const Member = Model.sequelize.import('../models/member');
//createMember Controller Method
exports.createMember = function(req, res, next) {
//Check if the cover image is attached
if(!req.file)
{
return res.status(400).json({message:'Attach Photo!'}); //The request is returning this response, meaning the file is never uploaded. And the file actually is not being uploaded
}
Member.create({
title: req.body.title,
fullname : req.body.fullname,
photo : req.body.req.file.path
}).then(member=>{
res.json(member);
}).catch((error)=>{
return res.json({status:500,error:error});
});
};
从请求中删除文件，其余数据按预期保存到数据库中
模型
//Models/member.js
'use strict';
module.exports = (sequelize, DataTypes) => {
var Member = sequelize.define('Member', {
fullname: DataTypes.STRING,
photo: DataTypes.STRING
}, {});
Member.associate = function(models) {
// associations can be defined here
};
return Member;
};
可能做错了什么。上传目录为空。请帮帮我。
