小白你还不会使用jwt吗？django实现jwt_django如何引入jwt

 配置key和时间【在setting中添加】

token_key = secrets.token_hex(16)
JWT_SECRET_KEY = token_key
JWT_EXPIRATION_DELTA = datetime.timedelta(days=1)

设置【在setting中添加】

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
        # 其他认证类...
    ),
}

创建一个构造函数

def create_jwt_token(username, password, role):
# payload 可以更改
    payload = {
        'password': password,
        'username': username,
        'role': role,
        'exp': datetime.utcnow() + settings.JWT_EXPIRATION_DELTA
    }
    return jwt.encode(payload, settings.JWT_SECRET_KEY, algorithm='HS256')
'
运行
运行

使用构造函数生成token

 token = create_jwt_token(username, password, role)
        res['token'] = token.decode('utf-8')

验证

前端在登录时候储存信息

 login() {
 
            axios.post("http://localhost:8000/api/login/", this.user).then(res => {
 
                if (res.data.code === 200) {
 
                    this.$message.success(res.data.msg)
 
                    localStorage.setItem('jwtToken', token);
 
                    setTimeout(() => {
 
                        location.href = "/"
 
                    }, 400)
 
                } else {
 
 
 
                    this.$message.error(res.data.msg)
 
                }
 
 
 
            })

调用储存的token

methods: {
    get_username() {
      // 获取存储在本地存储中的JWT令牌
      const token = localStorage.getItem('jwtToken');
      // 如果没有令牌，你可能需要进行一些处理，比如重定向到登录页面或者显示错误信息
      if (!token) {
        console.error("未找到JWT令牌");
        return;
      }
      // 将JWT令牌添加到请求标头中
      const headers = {
        'Authorization': `Bearer ${token}`
      };
      axios.get("http://localhost:8000/api/get_username/",
        { headers }
      ).then(res => {
        console.log(res);
        if (res.data.code[0] === 200) {
          this.username = res.data.username[0]
        } else {
          this.$message.error(res.data.msg)
        }
      })
    }
  },
  created() {
    this.get_username()
  }

后端解析jwt

import jwt
from django.conf import settings
from django.http import JsonResponse
from django.views import View
 
class IndexView(View):
    def get(self, request):
        res = {
            "msg": "获取token失败",
            "code": 425,
            "username": None,
            "role": None
        }
        token = request.headers.get('Authorization')
        # 解析token
        if not token:
            return JsonResponse(res)
        token = token.split(" ")[1]
        try:
            decoded_token = jwt.decode(token, settings.JWT_SECRET_KEY, algorithms=['HS256'])
            username = decoded_token['username']
            role = decoded_token['role']
        except jwt.ExpiredSignatureError:
            res["msg"] = "token已过期"
            return JsonResponse(res)
        except jwt.InvalidTokenError:
            res["msg"] = "token无效"
            return JsonResponse(res)
        res["code"] = 200,
        res["msg"] = "获取成功",
        res["username"] = username,
        res["role"] = role
        return JsonResponse(res)
