python小功能-递归解析Json

目的：解析Json格式的接口参数
用途：用于接口自动化测试，避免手工录入接口参数

1

Json格式的接口参数会有多种形式：数组、对象、数组和对象组合模式。

数组的实现方式：

[
{"id" : 1 ,"name" : "zhangsan"},
{"id" : 2 , "name" : "lisi"}
]

对象的实现方式：

{
    "meta":{
        "name":"南方有乔木",
        "cpCode":"mgtv",
        "genre":"happy"
     }
}

将json的参数解析出来并存入参数对象列表中。

def parseParamJson(suite_id):
    suite = TestSuite.objects.get(id=suite_id)
    paramList = json.loads(suite.json)
    newparams = []
    parentNodeName = ''
    parentNodeType = ''
    param = None
    typeName = None
    parseParam(paramList,parentNodeName,parentNodeType,typeName,param,newparams)
    for param in newparams:
        print("Param name :" + param.name)
        print("Param type :" + str(param.type))
        print("Param parentNodeName :" + param.parentNodeName)
        print("Param parentNodeType :" + param.parentNodeType)
        print("-------------------------------")


def parseParam(paramList,parentNodeName,parentNodeType,typeName,paramName,newparams):
    if not paramName is None :
        if type(paramName) != dict:
            parentNodeName = parentNodeName + '#' + paramName
        else:
            parentNodeName = parentNodeName + '#' + 'DefaultNodeTest'
    if not typeName is None:
           parentNodeType = parentNodeType + '#' + typeName

    if type(paramList) == list:
        for paramName in paramList:
            typeName = 'list'
            parseParam(paramName, parentNodeName, parentNodeType, typeName,paramName,newparams)
            break
    elif type(paramList) == dict:
        for paramName in paramList:
            typeName = 'dict'
            paramValue = paramList[paramName]
            parseParam(paramValue, parentNodeName, parentNodeType,typeName, paramName,newparams)
    else:
         param = TestSuiteParam()
         param.name = paramName
         param.type = type(paramList)
         param.parentNodeName = parentNodeName
         param.parentNodeType = parentNodeType
         newparams.append(param)

验证数组

Param name :id
Param type :<class 'int'>
Param parentNodeName :#DefaultNodeTest#id
Param parentNodeType :#list#dict
-------------------------------
Param name :name
Param type :<class 'str'>
Param parentNodeName :#DefaultNodeTest#name
Param parentNodeType :#list#dict
-------------------------------

验证对象

Param name :name
Param type :<class 'str'>
Param parentNodeName :#meta#name
Param parentNodeType :#dict#dict
-------------------------------
Param name :cpCode
Param type :<class 'str'>
Param parentNodeName :#meta#cpCode
Param parentNodeType :#dict#dict
-------------------------------
Param name :genre
Param type :<class 'str'>
Param parentNodeName :#meta#genre
Param parentNodeType :#dict#dict
-------------------------------
