“jsonschema”没有在Python中验证模式

Question

JSON记录应该是无效的，但它显示的值为True

import json
import jsonschema
dat='{"TID":"9020","CUR":"USD","DAT1":"t","DAT2":11}'

print type(dat)
def validJson(rowData):
    jsonRec=json.loads(rowData)
    jsonSc=json.loads('''{  "title": "NCAP", "type": "object",  "properties": { "TID" : { "type ": [ "string" ]  },"CUR" : { "type ": [ "string" ]  , "maxLength" : 3 },"DAT1" : { "type ": [ "number","null"]  , "maximum" : 99999999999 },"DAT2" : { "type ": [ "number" ,"null"]  , "maximum" : 112 } },  "required": [  "TID",  "CUR",  "DAT1",  "DAT2" ] }''')
    val = jsonschema.Draft3Validator(jsonSc).is_valid(jsonRec)
    print "is records valid ::"+str( val)
    va=jsonschema.validate(jsonRec, jsonSc)
    print "records validated "+str(va)
    return json.dumps(jsonRec)

print validJson(dat)

它应该是False的原因是DAT1数据类型是number，而它的值是“t”

或者，如果有人可以建议某种方法，让json记录根据其模式进行验证

您的type关键字后面有一个空格。Json模式不将其识别为关键字并忽略它。去掉多余的空间，它会像预期的那样工作。在
