Gradle系列六之Json操作

将实体对象转换成Json字符串

def list = [new Person(name: 'Jhon', age: 25),
            new Person(name: 'Alice', age: 26)]
def json = JsonOutput.toJson(list)
println json

打印输出为：

[{"age":25,"name":"Jhon"},{"age":26,"name":"Alice"}]

更优雅地显示Json字符串，可以调用JsonOutput.prettyPrint方法：

println JsonOutput.prettyPrint(json)

打印输出为：

[
    {
        "age": 25,
        "name": "Jhon"
    },
    {
        "age": 26,
        "name": "Alice"
    }
]

将Json字符串转换成实体对象

JsonSlurper jsonSlurper = new JsonSlurper()
def parseList = jsonSlurper.parseText(json)

网络访问请求

getNetworkData('https://home.firefoxchina.cn/?from=extra_start')
static def getNetworkData(String url) {
    def connection = new URL(url).openConnection() as HttpURLConnection
    connection.setRequestMethod('GET')
    connection.connect()
    def response = connection.content.text
    println response
}
