jenkins - 如何解析数据，并写入 JSON 文件

Question

在这里，我们将 JSON 内容中的值“dpidsha1”从 1234 替换为另一个值“abcd”，并面对一个将 JSON 格式的内容写入文件“uselessfile.json”时出错，并打印文件“uselessfile.json”的内容

import groovy.json.JsonBuilder
import groovy.json.JsonSlurper

def buildContent(){


def content = """
{
   "app":{ },
   "at":2,
   "badv":[ ],
   "bcat":[ ],
   "device":[ {
      "carrier":"310-410",
      "connectiontype":3,
      "devicetype":1,
      "dnt":0,
      "dpidmd5":"268d403db34e32c45869bb1401247af9",
      "dpidsha1":"1234" 
   },
   {
      "carrier":"310-410",
      "connectiontype":3,
      "devicetype":1,
      "dnt":0,
      "dpidmd5":"268d403db34e32c45869bb1401247af9",
      "dpidsha1":"1234" 
   }]
}"""

def slurped = new JsonSlurper().parseText(content)
def builder = new JsonBuilder(slurped)
builder.content.device.find{it.dpidsha1}.dpidsha1= "abcd"
println(builder.toPrettyString())

writeFile file: 'uselessfile.json', text: builder.toPrettyString(content)

  File file = new File("uselessfile.json")

  println "Below is the content of the file ${file.absolutePath}"
  println uselessfile.json

错误:

[Pipeline] End of Pipeline an exception which occurred: in field com.cloudbees.groovy.cps.impl.BlockScopeEnv.locals

Caused: java.io.NotSerializableException: groovy.json.JsonBuilder

我该如何解决这个问题？

Answer 1

我更愿意使用 Utility Jenkins Pipelines 的函数而不是 groovy 类。下面的管道工作。我最后简化了转储到屏幕以验证使用 bash cat 命令的结果。但结果就是我想的那样。

node('linux') {
  def content = """
  {
     "app":{ },
     "at":2,
     "badv":[ ],
     "bcat":[ ],
     "device":[ {
        "carrier":"310-410",
        "connectiontype":3,
        "devicetype":1,
        "dnt":0,
        "dpidmd5":"268d403db34e32c45869bb1401247af9",
        "dpidsha1":"1234" 
     },
     {
        "carrier":"310-410",
        "connectiontype":3,
        "devicetype":1,
        "dnt":0,
        "dpidmd5":"268d403db34e32c45869bb1401247af9",
        "dpidsha1":"1234" 
     }]
  }"""

  def slurped = readJSON text: content
  println (slurped)
  def builder = slurped
  builder.device.find{it.dpidsha1 == "1234"}.dpidsha1= "abcd"
  println(builder)

  writeJSON file: 'uselessfile.json', json: builder, pretty: 4
  sh 'cat uselessfile.json'
}
