Question

如何在groovy中使用json file循环遍历FOR？我可以使用.each来完成，但我处于一种情况/错误，我无法使用.each循环。

正在读取json文件并将其解析为对象。

json看起来像这样：

{
    "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}}"
        }
    }
}

注意：我可以修改json文件，如果需要使过程更简单..我尝试做的就是循环throgh并提取键的值。

所以给出了像这样的字符串中的json：

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}}"
        }
    }
}'''

你可以这样做：

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

循环使用C风格的For循环而不是使用每个循环
