我有下面的文件,這是JSON轉儲的結果。Json dump for key,在Python中對
"fdd6a102-359c-4527-8469-4ef01a9c0076": "[\n {\n \"resource_status\": \"CREATE_COMPLETE\", \n \"resource_name\": \"i4_instance_internal_port\", \n \"resource_type\": \"OS::Neutron::Port\", \n \"physical_resource_id\": \"5db1d412-9a43-45c7-b72d-0dbe4eb16497\", \n \"updated_time\": \"2017-07-14T09:00:44\"\n }, \n {\n \"resource_status\": \"CREATE_COMPLETE\", \n \"resource_name\": \"i3_instance\", \n \"resource_type\": \"OS::Nova::Server\", \n \"physical_resource_id\": \"50375d90-5b57-412e-afe3-fdddefbd2f41\", \n \"updated_time\": \"2017-07-14T09:00:44\"\n }, \n {\n \"resource_status\": \"CREATE_COMPLETE\", \n \"resource_name\": \"i3_v1_instance_volume\", \n \"resource_type\": \"OS::Cinder::Volume\", \n \"physical_resource_id\": \"6750dc3d-e682-4a0c-a177-83a7252822fb\", \n \"updated_time\": \"2017-07-14T09:00:44\"\n }\n]\n"
我覺得這個文件搞砸了。它的格式不正確。我研究瞭如何在JSON傾倒
def pp_another_json(myDict):
import io
try:
to_unicode = unicode
except NameError:
to_unicode = str
# Write JSON file
with io.open('data.json', 'w', encoding='utf8') as outfile:
str_ = json.dumps(myDict,
indent=4, sort_keys=True,
ensure_ascii=False)
outfile.write(to_unicode(str_))
class getstackList():
def getStackID(self):
stacks = get_objects('stacks')
myDict = {}
for stack in stacks:
try:
myDict[stack.id] = subprocess.check_output(["openstack", "stack", "resource", "list", stack.id, "-f", "json"])
pp_another_json(myDict)
except subprocess.CalledProcessError as e:
print("Error")
-f JSON的OpenStack堆棧資源列表的輸出來在下面的格式
[
{
"resource_status": "CREATE_COMPLETE",
"resource_name": "i4_instance_internal_port",
"resource_type": "OS::Neutron::Port",
"physical_resource_id": "5db1d412-9a43-45c7-b72d-0dbe4eb16497",
"updated_time": "2017-07-14T09:00:44"
},
{
"resource_status": "CREATE_COMPLETE",
"resource_name": "i3_instance",
"resource_type": "OS::Nova::Server",
"physical_resource_id": "50375d90-5b57-412e-afe3-fdddefbd2f41",
"updated_time": "2017-07-14T09:00:44"
},
]
現在我的問題
- JSON的轉儲文件沒有按我真的不像json。我怎樣才能得到它在適當的格式
- JSON轉儲文件是一個大的。所以我有關鍵的ID和值是其中有另一個字典的列表(我這樣認爲)如何在這種情況下獲取數據?
- 我需要檢查例如'resource_type'是OS :: Cinder :: Volume,我將如何得到它,否則,如果我需要獲取resource_type的值,我將如何得到它?
如果有人能解釋我我的json文件,這將會有所幫助。如果還是不行,請告訴我去,可以幫助我瞭解的嵌套字典
編輯鏈接:要取我下面做的價值,是給我ValueError異常:值過多解壓
with open('data.json') as data_file:
data_loaded = json.load(data_file)
for key, value in data_loaded:
print(data_loaded[key][0]['resource_status'])
你可以給data_loaded.values()的輸出嗎? –
鍵值相同,data_loaded中的值相同: ValueError:解壓值太多 –
您可以打印data_loaded並顯示輸出快照嗎? –
