【DJango项目】3.JWT验证

   安装配置

pip install djangorestframework-jwt


配置Setting.py 

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.BasicAuthentication',
    ),
}

JWT_AUTH = {
    'JWT_EXPIRATION_DELTA': datetime.timedelta(days=1),
}

　在序列化器中添加token属性 并且生成token

from rest_framework_jwt.settings import api_settings

class CreateUserSerializer(serializers.ModelSerializer):
    """
    创建用户序列化器
    """
    ...
    token = serializers.CharField(label='登录状态token', read_only=True)  # 增加token字段

    class Meta：
        ...
        fields = ('id', 'username', 'password', 'password2', 'sms_code', 'mobile', 'allow', 'token')  # 增加token
        ...

    def create(self, validated_data):
        """
        创建用户
        """
        # 移除数据库模型类中不存在的属性
        del validated_data['password2']
        del validated_data['sms_code']
        del validated_data['allow']
        user = super().create(validated_data)

        # 调用django的认证系统加密密码
        user.set_password(validated_data['password'])
        user.save()

        # 补充生成记录登录状态的token
        jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
        jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER
        payload = jwt_payload_handler(user)
        token = jwt_encode_handler(payload)
        user.token = token

        return user

在js前端 保存token

var vm = new Vue({
    ...
    methods: {
        on_submit: function(){
            axios.post(...)
                .then(response => {
                    // 记录用户的登录状态
                    sessionStorage.clear();
                    localStorage.clear();
                    localStorage.token = response.data.token;
                    localStorage.username = response.data.username;
                    localStorage.user_id = response.data.user_id;
                    location.href = '/index.html';
                })
                .catch(...)
        }
    }
