标题有问题。我将向您展示NodeJS中的代码。请求是blogRouter.delete
controllers / blog.js(仅删除方法)
const blogsRouter = require('express').Router()
const jwt = require('jsonwebtoken');
const Blog = require('../models/blog')
const User = require('../models/user')
blogsRouter.delete('/:id', async (request, response, next) => {
const token = getTokenFrom(request)
console.log('token: ',token)
try {
const decodedToken = jwt.verify(token, process.env.SECRET)
if (!token || !decodedToken.id) {
return response.status(401).json({ error: 'token missing or invalid' })
}
const userid = await User.findById(decodedToken.id)
const blogs = await Blog.findById(request.params.id)
if(blogs.user.toString() === userid.toString()) {
await Blog.findByIdAndRemove(request.params.id)
response.status(204).end()
} else {
response.status(404).end()
}
}catch(exception){next(exception)}
})
当我控制台日志令牌时,我通过辅助函数getTokenFrom获得空值
getTokenFrom
const getTokenFrom = request => {
const authorization = request.get('authorization')
if (authorization && authorization.toLowerCase().startsWith('bearer ')) {
return authorization.substring(7)
}
return null
}
在请求后令牌中工作正常。我能够创建博客。但是当我用delete方法做同样的事情时,它不会显示令牌。它说空。因此它正确地返回了我的getTokenFrom函数,但我希望能够以delete方法访问令牌,以便能够删除某些博客。
控制器/登录
const jwt = require('jsonwebtoken')
const bcrypt = require('bcryptjs')
const loginRouter = require('express').Router()
const User = require('../models/user')
loginRouter.post('/', async (request, response) => {
const body = request.body
const user = await User.findOne({username: body.username})
const passwordCorrect = user == null ?
false : await bcrypt.compare(body.password, user.passwordHash)
if(!(user && passwordCorrect)) {
return response.status(401).json({
error: "Invalid username or passowrd"
})
}
const userForToken = {
username: user.username,
id: user._id,
}
const token = jwt.sign(userForToken, process.env.SECRET)
response.status(200).send({token, username: user.username, name: user.name})
})
module.exports = loginRouter
https://prnt.sc/qfjgka->这是一张图片。我发送http.delete请求,并获得令牌null。必须提供JWT。我不知道这是我的错误。我尝试了很多事情,但是没有用。 我试图用token.request.jwt定义令牌,但后来我没有定义它。
我只需要通过blogRoute.delete方法以某种方式访问该令牌。
感谢前进
编辑:这是我的发布方法,当我在此处控制台登录令牌时,它会返回令牌的值,但是当我在删除方法中执行相同的操作时,它将无法正常工作
blogsRouter.post('/', async (request, response, next) => {
const body = request.body
console.log('body', body)
const token = getTokenFrom(request)
console.log('token: ', token)
try {
const decodedToken = jwt.verify(token, process.env.SECRET)
if (!token || !decodedToken.id) {
return response.status(401).json({ error: 'token missing or invalid' })
}
const user = await User.findById(decodedToken.id)
const blog = new Blog({
title: body.title,
author: body.author,
url: body.url,
likes: body.likes,
user: user._id
})
const savedBlog = await blog.save()
user.blogs = user.blogs.concat(savedBlog._id)
await user.save()
response.json(savedBlog.toJSON())
} catch(exception) {
next(exception)
}
})
答案 0 :(得分:0)
在记录请求标头的屏幕快照中,似乎没有授权标头,因此您遇到了错误。如果您能够成功发送授权标头,则该问题将得到解决。
顺便说一句,在每个路由中检查令牌并对其进行验证不是一个好的解决方案。
您最好使用身份验证中间件进行令牌验证。
1-)创建一个这样的身份验证中间件:
middleware \ auth.js
const jwt = require("jsonwebtoken");
module.exports = function(req, res, next) {
let token;
if (
req.headers.authorization &&
req.headers.authorization.startsWith('Bearer')
) {
token = req.headers.authorization.split(' ')[1];
}
if (!token) {
return res.status(401).json({ error: 'token missing' })
}
try {
const decoded = jwt.verify(token, process.env.SECRET);
req.user = decoded;
next();
} catch (ex) {
return res.status(400).json({ error: 'token invalid' })
}
};
2-)在需要身份验证的任何地方使用此身份验证中间件。现在我们的路线更短了。
const blogsRouter = require("express").Router();
const jwt = require("jsonwebtoken");
const Blog = require("../models/blog");
const User = require("../models/user");
const auth = require("../middleware/auth");
blogsRouter.delete("/:id", auth, async (request, response, next) => {
try {
const userid = request.user.id; //we set the user in the auth middleware, so we can access it like this
const blogs = await Blog.findById(request.params.id);
if (blogs.user.toString() === userid.toString()) {
await Blog.findByIdAndRemove(request.params.id);
response.status(204).end();
} else {
response.status(404).end();
}
} catch (exception) {
next(exception);
}
});
blogsRouter.post("/", auth, async (request, response, next) => {
try {
const body = request.body
const user = await User.findById(request.user.id);
const blog = new Blog({
title: body.title,
author: body.author,
url: body.url,
likes: body.likes,
user: user._id
});
const savedBlog = await blog.save();
user.blogs = user.blogs.concat(savedBlog._id);
await user.save();
response.json(savedBlog.toJSON());
} catch (exception) {
next(exception);
}
});
通过这种方式,您可以将令牌发送到授权标头中,格式为Bearer TOKEN.....
