python操作json文件获取内容

Posted 2021-03-21 Follow U Heart

写case时，将case 写到json文件比写到,写python一定要学会处理json

 

以下，是要处理的json

处理操作包括：打开json文件，获取json文件内容，关闭json文件，读取内容中的对应key的value

 

{
    "name": "BeJson",
    "url": "http://www.bejson.com",
    "page": 88,
    "isNonProfit": true,
    "address": {
        "street": "科技园路.",
        "city": "江苏苏州",
        "country": "中国"
    },
    "links": [
        {
            "name": "Google",
            "url": "http://www.google.com"
        },
        {
            "name": "Baidu",
            "url": "http://www.baidu.com"
        },
        {
            "name": "SoSo",
            "url": "http://www.SoSo.com"
        }
    ]
}

python实现：

#coding=utf-8
import json

class OperationJson:
    def __init__(self,file_name=None):    
        if file_name:
            self.file_name = file_name
        else:
            self.file_name = ‘./dataConfig/data.json‘
        self.data = self.get_data()
        
    def get_data(self):
        fp = open(self.file_name)
        data = json.load(fp)
        fp.close()
        return data
    
    def get_value(self,id):
        return self.data[id]

if __name__ == ‘__main__‘:
    opers = OperationJson()
    print opers.get_value(‘name‘)
