API方法與使用

jsonToBean JSON字符串轉(zhuǎn)對象

let objStr: string = '{"id":"No_1060701","name":"張三","age":20,"addr":"烏市天山區(qū)","work":"工程師","salary":9223372036854775807.2512,"user":{"id":"No_1060701","name":"張三","age":20,"addr":"烏市天山區(qū)","work":"工程師"}}';
let user = JSONUtil.jsonToBean(objStr, User);

beanToJsonStr 對象轉(zhuǎn)JSON字符串

let user: User = new User();
let str = JSONUtil.beanToJsonStr(user);

jsonToArray JSON字符串轉(zhuǎn)Array

let arrayStr = ResUtil.getRawFileContentStrSync('data_utils.json');
let array = JSONUtil.jsonToArray< DescribeBean >(this.arrayStr);
array.forEach((item, index) = > {
  LogUtil.error(`${index} - ${JSON.stringify(item)}`);
});

jsonToMap JSON字符串轉(zhuǎn)Map

let mapStr: string = '{"id":"NO_10000011","name":"王五五","age":"30","addr":"烏市天山區(qū)","work":"攻城獅","salary":9223372036854775807.2512}';
let map = JSONUtil.jsonToMap(mapStr);
map.forEach((value, key) = > {
  LogUtil.error(`${key} - ${value}`);
});

mapToJsonStr Map轉(zhuǎn)JSON字符串

let mapStr: string = '{"id":"NO_10000011","name":"王五五","age":"30","addr":"烏市天山區(qū)","work":"攻城獅","salary":9223372036854775807.2512}';
let map = JSONUtil.jsonToMap(mapStr);

isJSONStr 判斷是否是字符串格式j(luò)son

let objStr: string = '{"id":"No_1060701","name":"張三","age":20,"addr":"烏市天山區(qū)","work":"工程師","salary":9223372036854775807.2512,"user":{"id":"No_1060701","name":"張三","age":20,"addr":"烏市天山區(qū)","work":"工程師"}}';
let b1 = JSONUtil.isJSONStr(objStr);
let b2 = JSONUtil.isJSONStr("abcd1234");
