我正在尝试发送用户的数据以进行表达并使用create函数创建新用户 但显示错误404和找不到页面 为什么?
我的api端点(可在client / src / components / api-users中找到:
real_result = []
for key in result:
real_result.append((key, dict.get(key))
我用于注册的用户控制器:
async function create (data) {
try {
const resp = await fetch('/api/signup/' , { //error initiating here
method:'POST',
mode:"cors",
credentials:'include',
headers:{
'Content-Type': 'application/json ',
'Accept': 'application/json',
"Access-Control-Origin": "*"
},
body:JSON.stringify(data)
})
console.log(resp)
console.log(resp.body)
resp.headers.forEach(console.log);
return JSON.stringify(resp);
} catch (err) {
console.log(err)
}
}
export {
create
}
用于数据库连接的服务器js文件:
var jwt = require('jsonwebtoken');
var atob =require('atob')
var Cryptr = require('cryptr')
var cryptr = new Cryptr('q1w2e3r4t5y6u7i8o9p0p0o9i8u6y5t4r3e2w1q')
var db =require('../server')
const create = (req, res, next) =>{
first_name = req.body.first_name,
last_name = req.body.last_name,
username =req.body.username,
password= req.body.password,
email=req.body.email,
dec_pass =atob(toString(req.body.password)),
encrypted_pass =cryptr.encrypt(dec_pass)
var sql = "INSERT INTO `user`(`user_id`,`first_name`,`last_name`,`username` , `email`,`password`) VALUES ('','" + first_name + "','" + last_name + "','" + username + "','" +email+ "','" +encrypted_pass+ "')";
var query = db.query(sql, function(err, result){
console.log(query)
console.log(req)
return (JSON.stringify(result));
});
};
export
{ create }
亩用户路线:
var Sequelize = require('sequelize')
var app = require('./app')
var CONFIG= require('../config/CONFIG')
const db = {}
const sequelize = new Sequelize ("users" , "root" , "" ,{
host:'localhost',
dialect:'mysql',
operatorAliases:false,
pool:{
max:5,
min:0,
acquire:30000,
idle:10000
}
})
console.log(CONFIG.db_host)
db.sequelize=sequelize
db.Sequelize=Sequelize
console.log('alright')
export default db
我的signupjs反应文件
const express = require('express');
const router = express.Router();
var userCtrl = require ('../controllers/user.controller')
router.post('/signup', userCtrl.create)
module.exports = router
答案 0 :(得分:0)
正如@Deep Kakkar所述,您没有设置api
前缀,因此您应该找到/signup
而不是/api/signup
fetch(/api/signup)
还会在您当前域(响应应用程序已打开的地方)上到达此相对路径,因此您需要设置完整路径,例如,如果您的http-server
在端口{ {1}},而您的应用程序已在4000
上运行,那么您应该获取3000
而不是http://localhost:4000/api/signup
,因为它将是/api/signup

本地主机:3000 / api / products 404错误 您没有在server.js上创建res.get(“ / api / products”)或未设置代理。请在下面检查代理设置。
代理错误:无法代理请求/ api / products 检查一下:
frontend / package.json
{ “ name”:“ frontend”, “ proxy”:“ http://127.0.0.1:5000”, ... }
停止运行前端和后端
先运行后端
npm开始
然后是前端
cd前端 npm开始
