[英]Extract the value from an array in Apache NiFi
I have a JSON with this structure:我有一个 JSON 这种结构:
{
"documentos": [
{
"valorNota": 229.2,
"tipoDocumento": "PRE_NOTA_FISCAL",
"cnpjEmissorNota": "02130525000177",
"cnpjRemetente": "02130525000177",
"cnpjUnidade": "02130525000177",
"cnpjDestinatario": "14586674000124",
"valorFreteRealizadoNota": 0,
"serie": "1",
"valorFreteCalculadoNota": 1000,
"tipoOperacao": "SAIDA",
"dataEmissao": "2022-12-05 11:03:00",
"numeroNota": 744659
}
],
"dataEmissaoConhecimento": "2022-12-05 11:03:00.0",
"localizacaoDestinoConhecimento": 3002171,
"localizacaoOrigemConhecimento": 3001956,
"cepOrigemConhecimento": 44079006,
"cepDestinoConhecimento": 48880000,
"valorFreteRealizadoConhecimento": 0,
"oidConhecimento": 10802880097,
"valorFreteCalculadoConhecimento": 1000
}
I need to extract the value of "numeroNota"
(can be with EvaluateJsonPath or other processor).我需要提取
"numeroNota"
的值(可以使用EvaluateJsonPath或其他处理器)。
How can I do this?我怎样才能做到这一点?
Thanks谢谢
One option is to use a shift transformation spec within a JoltTransformJSON processor such as一种选择是在JoltTransformJSON处理器中使用移位转换规范,例如
[
{
"operation": "shift",
"spec": {
"docu*": { //the level of "documentos" array
"*": { //the indexes of the array
"numeroN*": "" //yields the value of the attribute without any wrapper
}
}
}
}
]
which returns 744659 as result for the current case返回744659作为当前案例的结果
