Groovy JSON 轉換為 CSV

Question

我在 groovy 中通過 JsonSlurper 解析 Json 時遇到問題。 你能幫忙嗎？ 我的示例 json 是：

{
   "expand": "schema,names",
   "startAt": 0,
   "maxResults": 50,
   "total": 21,
   "issues":    [
            {
         "expand": "operations,versionedRepresentations",
         "id": "217580",
         "self": "issue/217580",
         "key": "ART-4070",
         "fields": {"summary": "#[ART] Pre.3 Verification \"S\""}
      },
            {
         "expand": "operations,versionedRepresentations",
         "id": "217579",
         "self": "issue/217579",
         "key": "ART-4069",
         "fields": {"summary": "Verification \"C\""}
      },
            {
         "expand": "operations,versionedRepresentations",
         "id": "217577",
         "self": "issue/217577",
         "key": "ART-4068",
         "fields": {"summary": "#[ART] Enum type"}
      },
   ]
}

結果，我期待一個包含密鑰列表的 csv 文件，僅摘要：

key,summary
ART-4070,#[ART] Pre.3 Verification \"S\"
ART-4069,Verification \"C\"
ART-4068,#[ART] Enum type

當我嘗試開始代碼解析這個 json 時，我有一個錯誤：線程“main”groovy.json.JsonException 中的異常：期望 '}' 或 ',' 但得到當前字符 'S' 的 int 值83

當前讀取的字符是 'S'，int 值為 83，期待 '}' 或 '，但得到當前字符 'S'，int 值為 83 行號 13 索引號 321 "fields": {"summary": "#[ART] Pre.3 驗證"S""}

代碼：

import groovy.json.*

def jsonSlurper = new JsonSlurper()
def json = '''
{
   "expand": "schema,names",
   "startAt": 0,
   "maxResults": 50,
   "total": 21,
   "issues":    [
            {
         "expand": "operations,versionedRepresentations",
         "id": "217580",
         "self": "issue/217580",
         "key": "ART-4070",
         "fields": {"summary": "#[ART] Pre.3 Verification \"S\""}
      },
            {
         "expand": "operations,versionedRepresentations",
         "id": "217579",
         "self": "issue/217579",
         "key": "ART-4069",
         "fields": {"summary": "Verification \"C\""}
      },
            {
         "expand": "operations,versionedRepresentations",
         "id": "217577",
         "self": "issue/217577",
         "key": "ART-4068",
         "fields": {"summary": "#[ART] Enum type"}
      },
   ]
}
'''
def obj = jsonSlurper.parseText(json)
println obj

請幫忙

第一：您需要在'''字符串中使用雙\\\\ ； 其次,列表的最后一個元素上有一個, 。

import groovy.json.JsonSlurper

def jsonSlurper = new JsonSlurper()
def json = '''
{
   "expand": "schema,names",
   "startAt": 0,
   "maxResults": 50,
   "total": 21,
   "issues":    [
            {
         "expand": "operations,versionedRepresentations",
         "id": "217580",
         "self": "issue/217580",
         "key": "ART-4070",
         "fields": {"summary": "#[ART] Pre.3 Verification \\"S\\""}
      },
            {
         "expand": "operations,versionedRepresentations",
         "id": "217579",
         "self": "issue/217579",
         "key": "ART-4069",
         "fields": {"summary": "Verification \\"C\\""}
      },
            {
         "expand": "operations,versionedRepresentations",
         "id": "217577",
         "self": "issue/217577",
         "key": "ART-4068",
         "fields": {"summary": "#[ART] Enum type"}
      }
   ]
}
'''
def obj = jsonSlurper.parseText(json)
println obj
