How Can I Filter Attribute From Json File Using Nifi Stack Overflow

How Can I Filter Attribute From Json File Using Nifi Stack Overflow I'm able to extract attributes from json by using evaluatejsonpath processor. updateattribute is the processor where i want to extract the attributes. please find below snapshot of updateattribute processor when value of "country="es" i want get json file like this: "eventtype": "update", "eventtime": "2021 12 14t12:34:56.789012z", "country": "es",. I need to fetch the second attribute from a json file. and have tried to use 'evaluatejsonpath' processor and or 'attributetojson' processor, in both of which case i always get the whole line instead of single attribute.

How Can I Filter Attribute From Json File Using Nifi Stack Overflow I have been trying to filter out just the required attributes from the payload. the required attributes could be passed as an array or added to the existing payload. I'd recommend starting with a combination of listfile and fetchfile (or getfile on its own) to retrieve the archive, compresscontent to extract the component files, routeonattribute using the flowfile filename attribute to separate the flowfile containing category.json, and the evaluatejsonpath processor to retrieve the json content of that. I have a same task to extract attributes from json file via gethttp with evaluatejsonpath processor. however, the resulting data from the processor do not limit to the attributes, it pulled all attributes the original json data has.

Filters the attributes of a flowfile by retaining specified attributes and removing the rest or by removing specified attributes and retaining the rest. tags: attributes, modification, filter, retain, remove, delete, regex, regular expression, attribute expression language properties: in the list below, the names of required properties appear. You will need to make sure that the information that your gethttp processor outputs is strictly json, then feed it into evaluatejsonpath. from there, you can reference the fields in the json and forward them on to other processors. One way that we recently extended nifi to improve this scenario is created a custom processor that uses an attribute to map to a corresponding key from a json object stored in the variable registry in nifi. While flowfiles have content, they also have attribute (metadata that describes the content). sometimes, it’s useful to convert specific pieces of content into attributes for easier processing and routing.
