问题 The question is still relevant! In my task, json comes to my input, which I do not know in advance.

GetClass () *. SimpleName But I am faced with a problem when the same field in the first json block is null, and in the second the integer and the type is defined as null, and not as Integer. How to

Groovy: validate JSON string

由 断了今生、忘了曾经 提交于 2020-07-18 04:09:26
问题 I need to check that a string is valid JSON in Groovy. My first thought was just to send it through new JsonSlurper().parseText(myString) and, if there was no exception, assume it was correct. However, I discovered that Groovy will happily accept trailing commas with JsonSlurper , but JSON doesn't allow trailing commas. Is there a simple way to validate JSON in Groovy that adhere's to the official JSON spec? 回答1: JsonSlurper class uses JsonParser interface implementations (with

问题 I need to implement a method that will scan a string of JSON for a particular targetField and either return the value of that field (if it exists), or null (if it doesn't): // Ex: extractFieldValue(/{ "fizz" : "buzz" }/, 'fizz') => 'buzz' // Ex: extractFieldValue(/{ "fizz" : "buzz" }/, 'foo') => null String extractFieldValue(String json, String targetField) { // ... } This solution has to be recursive and work at any nesting-level in the (hierarchical) JSON string. Also it needs to work for

How to get key from ArrayList nested in JSON using Groovy and change its value

问题 I need to be able to find the key quote.orderAttributes[0].attributeDetail.name and set its value to null or any other value I want. I only need to do this for the first element in any list so selecting [0] is fine. I want to be able to use a path such as 'quote.orderAttributes.attributeDetail.name'. But given the amount of time I've spent so far, please advise of any better approaches. Here is the Json: { "source": "source", "orderId": null, "Version": null, "quote": { "globalTransactionId":

问题 I have a method that returns fairly-nested JSON such as: [[fizz: buzz, foos: [[count: 4, flim: flam], [count: 6, flim: flume]]]] When I try to use JsonSlurper to slurp this JSON into a def result I am getting exceptions: // json == “[[fizz: buzz, foos: [[count: 4, flim: flam], [count: 6, flim: flume]]]]" String json = getJSON() JsonSlurper slurper = new JsonSlurper() def result = slurper.parseText(json) Produces an exception thrown when parseText executes: Caught: groovy.json.JsonException:
