怎样操作json对象及数组键值大小写转换

前言

最近在做一个项目，发现后端返回的数据键值全部都是大写的，有时候前端用起来很不方便，所以写了一个深度转换的小工具，分享给大家，也就不用重复造轮子了，不喜勿喷，下面话不多说了，来一起看看详细的介绍吧。

start

npm i deep-lu-trans --save

json example

import t from 'deep-lu-trans';
const obj = {
 AS_DD_S: 123213,
 AND_SAJ_JDK_JSAKD_: {
 DJK_ASJ: {
  SA_DSA_DSA: 123123,
  ASDA_SDH_KAS: {
  ASD_SAD: [{
   ASD_SAD_SA: 123123,
   III_ASDA: [1, 23, {
   ASD_SAD: 123
   }]
  }]
  }
 }
 },
 KIO: [{
 OP: 1,
 OOP: 2
 }, {
 OL: 1,
 OP: 2
 }]
};
t.objKeysToLower(obj).then((res) => {
 console.log(JSON.stringify(res));
});
t.objKeysToLower(obj).then((res) => {
 console.log(JSON.stringify(res));
 /*
 {"as_dd_s":123213,"and_saj_jdk_jsakd_":{"djk_asj":{"sa_dsa_dsa":123123,"asda_sdh_kas":{"asd_sad":[{"asd_sad_sa":123123,"iii_asda":[1,23,{"asd_sad":123}]}]}}},"kio":[{"op":1,"oop":2},{"ol":1,"op":2}]}
 */
 t.objKeysToUpper(res).then((_s) => {
 console.log(JSON.stringify(_s));
 /*
 {"AS_DD_S":123213,"AND_SAJ_JDK_JSAKD_":{"DJK_ASJ":{"SA_DSA_DSA":123123,"ASDA_SDH_KAS":{"ASD_SAD":[{"ASD_SAD_SA":123123,"III_ASDA":[1,23,{"ASD_SAD":123}]}]}}},"KIO":[{"OP":1,"OOP":2},{"OL":1,"OP":2}]}
  */
 });
});

array example

import t from 'deep-lu-trans';
const arr = [{
 A_B: 1,
 B_C: 2
}, 3, 4, 'abc', [{
 A_B: 1,
 B_C: {
 C_D: [0, {
  CK: 1,
  KL: 2
 }]
 }
}]]
t.arrKeysToLower(arr).then((res) => {
 console.log(JSON.stringify(res));
 /*
 [{"a_b":1,"b_c":2},3,4,"abc",[{"a_b":1,"b_c":{"c_d":[0,{"ck":1,"kl":2}]}}]]
 */
 t.arrKeysToUpper(res).then((_s) => {
 console.log(JSON.stringify(_s));
 [{"A_B":1,"B_C":2},3,4,"abc",[{"A_B":1,"B_C":{"C_D":[0,{"CK":1,"KL":2}]}}]]
 });
})
