readJSON: Read JSON from files in the workspace.

Reads a file in the current working directory or a String as a plain text JSON file. The returned object is a normal Map with String keys or a List of primitives or Map.

Example:

def props = readJSON file: 'dir/input.json'
assert props['attr1'] == 'One'
assert props.attr1 == 'One'

def props = readJSON text: '{ "key": "value" }'
assert props['key'] == 'value'
assert props.key == 'value'

def props = readJSON text: '[ "a", "b"]'
assert props[0] == 'a'
assert props[1] == 'b'

def props = readJSON text: '{ "key": null, "a": "b" }', returnPojo: true
assert props['key'] == null
props.each { key, value ->
    echo "Walked through key $key and value $value"
}
	

• file (optional)

  Path to a file in the workspace from which to read the JSON data. Data could be access as an array or a map.

  You can only specify file or text, not both in the same invocation.

  • Type: String
• returnPojo (optional)

  Transforms the output into a POJO type (LinkedHashMap or ArrayList) before returning it.

  By default deactivated (false), and a JSON object (JSONObject or JSONArray from json-lib) is returned.

  • Type: boolean
• text (optional)

  A string containing the JSON formatted data. Data could be access as an array or a map.

  You can only specify file or text, not both in the same invocation.

  • Type: String

def sonarHttpRequest(method,apiUrl){
    sonarApi = "http://139.198.166.235:9000/api"
    response = sh returnStdout: true, script:
    """
    curl --location \
    --request ${method} \
    ${sonarApi}/${apiUrl} \
    --header 'Authorization: Basic YWRtaW46YWRtaW4xMjM='
    """
    response = response - "\n"

    try{
         result = readJSON text: "${response}"
    }catch(e){
         result = ""
    }

    return result
}

 扩展流水线解析JSON数据

安装插件： Pipeline Utility Steps

现在不想在触发器里面去写这些一个一个的变量了，但是还是想获取变量的值，那么需要插件。

 我们会使用到这个插件的resdJSON方法，是用来专门用来处理json数据的。如果不知道怎么使用这个插件可以在片段生成器里面查看，有处理文本和处理json数据，最后赋值给变量。

def webHookData = readJSON text: "${allData}"

String name1 = webHookData["name"]
String name2 = webHookData.name

String groupName1 = webHookData["group"]["name"]
String groupName2 = webHookData.group.name


pipeline {
    agent any

    stages {
        stage('webHook') {
            steps {
             println("所有body数据 --> ${allData}")
             println(name1)
             println(name2)
             println(groupName1)
             println(groupName2)
             
            }
        }
    }
}

 所以有两种方法，一种是在webhook里面将每个参数都写出来，另外一种是使用readJSON去处理。
