flask 使用錯誤總結

1、發送請求時服務端報如下錯誤

Traceback (most recent call last):

 File "/usr/lib/python2.7/site-packages/flask/app.py", line1475, in full_dispatch_request

   rv = self.dispatch_request()

    raiseself.mapping[code](*args, **kwargs)

InternalServerError: 500: Internal ServerError

原因：

class TasksAPI(Resource):
    def __init__(self):
        self.reqparse = reqparse.RequestParser()
        self.reqparse.add_argument('ip', type=list, location='json', required=True)
        self.reqparse.add_argument('user', type=str, location='json', required=True)
        self.reqparse.add_argument('password', type=str, location='json', required=False)
        self.reqparse.add_argument('private_key', type=str, location='json', required=False)
        self.reqparse.add_argument('taskname', type=str, location='json', required=True)
        self.reqparse.add_argument('args', type=dict, location='json', required=False)

有些參數設置爲 required=True,但發送請求時並沒有帶此參數。
