在C風格的循環For循環而不是使用每個

Question

如何在groovy中使用FOR循環通過json file循環？我能夠做到這一點.each，但我處於一種情況/錯誤，我不能使用.each循環。

正在讀取json文件並將其解析爲一個對象。

JSON的是這樣的：

{ 
    "workflows1": { 
     "name": "/wf_multifolder", 
     "file": "release1/wf_multifolder.XML", 
     "folderNames": { 
      "multifolder": "{{multifolder}}", 
      "agent1": "{{agentx}}" 
     } 
    }, 
    "workflows2": { 
     "name": "/wf_multifolder", 
     "file": "release1/wf_multifolder.XML", 
     "folderNames": { 
      "multifolder": "{{multifolder}}", 
      "agent1": "{{agentx}}" 
     } 
    } 
} 

注：我可以修改JSON文件，如果需要簡化流程。所有我正在嘗試做的是循環throgh並提取值按鍵。

所以給出的JSON的字符串，像這樣：

def jsonText = '''{ 
    "workflows1": { 
     "name": "/wf_multifolder", 
     "file": "release1/wf_multifolder.XML", 
     "folderNames": { 
      "multifolder": "{{multifolder}}", 
      "agent1": "{{agentx}}" 
     } 
    }, 
    "workflows2": { 
     "name": "/wf_multifolder", 
     "file": "release1/wf_multifolder.XML", 
     "folderNames": { 
      "multifolder": "{{multifolder}}", 
      "agent1": "{{agentx}}" 
     } 
    } 
}''' 

你可以這樣做：

import groovy.json.* 

def json = new JsonSlurper().parseText(jsonText) 

for(entry in json) { 
    println "$entry.key has file $entry.value.file" 
} 

打印：

workflows1 has file release1/wf_multifolder.XML 
workflows2 has file release1/wf_multifolder.XML
