The use of Jsonschema in the development of interface

1. Import the module

Import jsonschemafrom jsonschema import schemas,validatorsfrom jsonschema.validators import Draft4validator

2. Custom Parameter Validation rules

schema = {    ' description ': ' Validate the request json data parameter ',    ' type ': ' object ',    ' properties ': {'       sender ': {'           type ' ': ' String ',       },        ' Msgtype ': {            ' type ': ' String '        },        ' receiver ': {            ' type ': ' String '        },        ' msg ': {            ' type ': ' object ',            ' content ': {' type ': ' String '},            ' Required ': [' type ', ' content ']        }    },    ' Required ': [' sender ', ' receiver ', ' msg '}

3. Specific Use

Class Validator (object):    def __init__ (self, name):        self.schema = name        Checker = Jsonschema. Formatchecker ()        self.validator = validators. Draft4validator (self.schema,format_checker=checker)    def validate (self,data):        try:            Self.validator.validate (data)            return True        except Jsonschema. ValidationError as ex:            raise Exception (ex.message)            return falseverifi_obj = Validator (Schema) # You can write a py file separately, Data is to be validated, call the Validate method
