自定义返回jwt验证数据

jwt数据返回

1. 验证成功时候：

   1. 创建有给utli文件，重写jwt_response_payload_handler方法

      	def jwt_response_payload_handler(token, user=None, request=None):
      	    return {
      	        'token': token,
      	        'id': user.id,
      	        'username': user.username,
      	    }
      

   2. 在setting里面进行配置：

      	JWT_AUTH= {
      	JWT_RESPONSE_PAYLOAD_HANDLER': 'drf.utils.jwt_response_payload_handler',
      	}
      

2. 验证失败的时候

   1. 需要修改一下源码
      
      

3. 创建一个**`custom_exception**文件

   from rest_framework.views import exception_handler
   from rest_framework.exceptions import ValidationError
   
   
   def custom_exception_handler(exc, context):
       response = exception_handler(exc, context)
   
       if isinstance(exc, ValidationError):
           response.data['code'] = response.status_code
           response.data['data'] = []
           if isinstance(response.data, dict):
               response.data['message'] = list(dict(response.data).values())[0][0]
   
               for key in dict(response.data).keys():
                   if key not in ['code', 'data', 'message']:
                       response.data.pop(key)
           else:
               response.data['message'] = '输入有误'
           return response
   
       if response is not None:
           response.data.clear()
           response.data['code'] = response.status_code
           response.data['data'] = []
   
           if response.status_code == 404:
               try:
                   response.data['message'] = response.data.pop('detail')
                   response.data['message'] = "未找到"
               except KeyError:
                   response.data['message'] = "未找到"
   
           if response.status_code == 400:
   
               response.data['message'] = '输入错误'
   
           elif response.status_code == 401:
               response.data['message'] = '未认证'
   
           elif response.status_code >= 500:
               response.data['message'] = "服务器错误"
   
           elif response.status_code == 403:
               response.data['message'] = "权限不允许"
   
           elif response.status_code == 405:
               response.data['message'] = '请求不允许'
           else:
               response.data['message'] = '未知错误'
       return response
   

4. 在setting里面进行配置

   'EXCEPTION_HANDLER': (
       'app06.custom_exception.custom_exception_handler'
   

)
```
