Nifi JoltTransformJSON:在键名中保留下划线符号
Nifi JoltTransformJSON : Keeping the underscore sign in key name
我正在尝试在 Apache Nifi 中编写一个 jolt 来转换 json 形式。我设法转换了震动,但缺少一个属性下划线:
输出:
{
"Source": { //source is missing underscore. It should look like _Source
"userName": "Lulu"
}
}
我的输入如下:
{
"user_name": "Lulu"
}
目前我的震惊表情如下:
[
{
"operation": "shift",
"spec": {
"user_name":"userName"
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"_Source":{
"userName":"@(2,userName)"
}
}
},
{ "operation": "remove",
"spec": {
"userName": "" }
}
]
如何在属性 "Source" 中保留下划线符号?
我一直在搞清楚这部分。我想知道我在震惊的表情中遗漏了什么。提前致谢,伙计们
我认为下划线可能是该运算符中的某种特殊字符,请在 _Source:
前面尝试 double-backslashes
[
{
"operation": "shift",
"spec": {
"user_name": "userName"
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"\_Source": {
"userName": "@(2,userName)"
}
}
},
{
"operation": "remove",
"spec": {
"userName": ""
}
}
]
一个人就能搞定"shift"。
