Python如何展平json_normalize之类的json文件

问题描述 投票：0回答：1

我正在尝试解析和展平以下文件，以查看嵌套内容，例如json_normalize的输出，就像在单独列上的每个嵌套对象一样。

json文件内容：

{"name":"Trace","fields":{"time":"2020-03-11 16:44:55.860"},"layers":[{"name":"EVENT","fields":{"recordLength":56,"recordType":4,"eventId":5240,"ZZ_RECEIVED":{"EVENT_PARAM_TIMESTAMP_HOUR":16,"EVENT_PARAM_TIMESTAMP_MINUTE":44,"EVENT_PARAM_TIMESTAMP_SECOND":55,"EVENT_PARAM_TIMESTAMP_MILLISEC":860,"EVENT_PARAM_SCANNER_ID":262144,"EVENT_PARAM_RBS_MODULE_ID":"EVENT_VALUE_MASTER_DU (0)","EVENT_PARAM_GLOBAL_XX_ID":1840928,"EVENT_PARAM_ZZAPID":264166,"EVENT_PARAM_VELIID":267794859,"EVENT_PARAM_GALI":"'00 82 F6 10 00 02 C8'H","EVENT_PARAM_RAC_UE_REF":271663231,"EVENT_PARAM_TRACE_RECORDING_SESSION_REFERENCE":"'00 11 65'H","EVENT_PARAM_MEASUREMENT_ID":1,"EVENT_PARAM_MEAS_REQUESTER":"EVENT_VALUE_TRAFFIC (0)","EVENT_PARAM_NEIGHBOR_CGI":"'00 82 F6 10 01 5C 00 C0'H","EVENT_PARAM_AFFECTED_MEAS_TYPE":"EVENT_VALUE_EVENT_A3 (2)","EVENT_PARAM_RAT_TYPE":"EVENT_VALUE_EUTRAN_INTRA_FREQUENCY (0)","EVENT_PARAM_MEAS_CAUSE":"EVENT_VALUE_NOT_APPLICABLE (2)","EVENT_PARAM_PADDING_2":"'00 00'H"}}}]}

我的代码是：

jsonfilename='c:\\temp\\dec_lite.json'
data = []
with open(jsonfilename) as f:
    for line in f:
        data.append(json.loads(line))

df=pd.DataFrame()
df = pd.json_normalize(data)

igot：

我如何像在单独列上的每个嵌套对象一样将内容像json_normalize的内容展平？：

ex：

name | fields.time | layers.name | layers.fields.recordLength |  etc..
python json flatten normalize

我终于设法做到了：

mydict={}
f=gzip.open(jsonfilename, 'rt', encoding='utf-8')
for line in f:
    mydict.append(json.loads(line))

df=pd.DataFrame()
df=pd.json_normalize(mydict,'layers','fields','zaman')
