從複雜的JSON數據中獲取所需的值

Question

從下面的JSON響應中，我只想得到bkg鍵的值並將所有這些值附加到列表中。

從這個特定的數據，我想最終結果爲[244332，1066459，1354690，1300150，472468，300420，722942]

Answer 1

根據您的JSON格式，你可以這樣做：

your_json['data'].keys() 

Answer 2

希望這會有所幫助。

result = [] 
json = {u'data': {u'244332': {u'hotel_data_node': {u'_id': 919824916605752258L, u'ids': {u'bkg': [u'244332'], u'voy': 9174725345440343760L}, u'vendor_info': {u'vendor_id': u'244332', u'vendor': u'bkg'}}}, 

u'1066459': {u'hotel_data_node': {u'_id':2735067627304153118L, u'ids': {u'bkg': [u'1066459'], u'voy': 6032400126419907661L}, u'vendor_info': {u'vendor_id': u'1066459', u'vendor': u'bkg'}}}, 

u'1354690': {u'hotel_data_node': {u'_id': 2001829735393701201L, u'ids': {u'bkg': [u'1354690'], u'voy': 5694961161423235761L}, u'vendor_info': {u'vendor_id': u'1354690', u'vendor': u'bkg'}}}, 

u'1300150': {u'hotel_data_node': {u'_id': 2937209460187035224L, u'ids': {u'bkg': [u'1300150'], u'voy': 2447701064370670892L}, u'vendor_info': {u'vendor_id': u'1300150', u'vendor': u'bkg'}}}, 

u'472468': {u'hotel_data_node': {u'_id': 48272593877071744L, u'ids':{u'bkg': [u'472468'], u'voy': 658992090378786622L}, u'vendor_info': {u'vendor_id': u'472468', u'vendor': u'bkg'}}}, 

u'300420': {u'hotel_data_node': {u'_id': 2802488975195270489L, u'ids': {u'bkg': [u'300420'], u'voy': 8506688262306690280L},u'vendor_info': {u'vendor_id': u'300420', u'vendor': u'bkg'}}},

for key in json['data']: 
    result += json['data'][key]['hotel_data_node']['ids']['bkg'] 
print(result) 
>>>[u'244332', u'1066459', u'1354690', u'1300150', u'472468', u'300420', u'722942'] 

Answer 3

我想這是一個重複問題，請參考：

Accessing JSON elements

也爲 'U' 的緣故：

Python: json.loads returns items prefixing with 'u'
