将Web服务中的json响应转换为python中的字典或对象

标签： python json google-drive-api

我有一个小的python部分代码 - 

self.drive_service = build('drive', 'v2', http=self.http)        
result = self.retrieve_all_files(self.drive_service)
print "result recieved \n"
rootNode = root()
for item in result:
    print "item \n" 
    print item
    if(item["parents"]["isRoot"]==true):
        node = root()
        node.setData(item)
        rootNode.add_child(node)
    else:
        node = rootNode.findParent(item["parents"]["id"])
        print node
        newNode = root()
        newNode.setData(item)
        node.add_child(newNode)

现在在这个函数中，我得到的输出就像 - 

item

现在我试过了

item["parents"]
item.parents
json.loads(result) ["which says not a string or buffer as result is an array object so tried str(result) too ]

但是，无法访问其属性。我怎么在python中做到这一点？

item.parents是一个dicts列表。您需要访问item.parents[0]['isRoot']，或者遍历父列表中的值。

答案 1 :(得分：0)

你可以通过以下方式获得价值

json_data={u'mimeType': u'application/vnd.google-apps.folder', u'version': u'17', u'appDataContents': False, u'labels':u'aaaa'}
data = json.dumps(json_data)
json_to_python = json.loads(data)
print (json_to_python['version'])
