三、实践
1.$.filed1.field2
from jsonpath_ng import jsonpath,parse
json_str = {"data":{
"ecifId":"2022100400000103",
"operationId":"1628612966502549718749141715287189397281668389298609270",
"operationStatus":100,
"pinSetedFlag":"1",

},
"success":True}
expre_str = parse('$.data.operationStatus')
data = expre_str.find(json_str)
print("operationStatus:",data[0].value)
