我有一个wordpress网站，并且我有一个API，可以将帖子导出为Json。我正在用此新闻建立一个新网站，但是我必须获取这个Json文件，并以某种方式将其格式化为带有我的属性名称的新Json文件。我也想从中丢弃一些属性。因此，这是我从帖子中得到的一个Json的简单示例：
return如何制作脚本，例如以以下格式输出此json：
{
"status": "ok",
"post": {
"id": 2335,
"type": "post",
"slug": "litoral-awards14-no-jornal-diario-porto-canal",

例如，我想说：originalJson.status = newJson.status。 originalJson.author.id = newJson.author。 originalJson.thumbnail.url = newJson.images.thumbnail_image。希望你明白我的意思。 您还可以在我得到的json上，在originalJson.post.content上看到我有很多html，例如：
{
"status": "ok",
"slug": "litoral-com-teste-noticia-url",
"title": "Titulo de teste",
"type": "post",
"content": "Lorem",
"published": 1,
"excerpt": "",
"categories": [1, 2, 4],
"tags": [1, 2, 4],
"author": 1,
"comments": {
"user_comment": 1,
"body_comment": "comentario de teste"
},
"images": {
"thumbnail_image": "http://wwww.imagem.com.jpeg",
"featured_image": "http://wwww.imagem.com.jpeg"
}
}
将此信息传递到新的json时，削减所有div的最佳方法是什么？我只想要div内的内容。我该如何实现？
我尝试搜索此文件，但找不到。基本上，我该如何制作像JS脚本那样的脚本，该脚本将获得旧的Json文件作为输入，并输出一个新的json文件，但是仅包含我想要的属性，并且还重命名了我解释过的大多数属性。
感谢任何帮助人员！
答案 0 :(得分：1)
对于第一个问题，假设您不想动态指定想要的字段，可以通过执行以下操作使它看起来更简洁：
newJson = {
status: oldJson.status,
author: oldJson.author
}
第二个问题：
我能想到的最接近删除div的方法是：
但是，如果我处于您的位置，我将首先尝试寻找其他方法来获取html数据，而不是字符串操作。
答案 1 :(得分：1)
如果您有有效的html字符串，则可以使用此函数提取文本：
function extractText(selector, html) {
const elem = document.createElement('div');
elem.innerHTML = html;
return elem.querySelector(selector).innerText;
}
您可以像这样使用它：
const caption = extractText('p.wp-caption-text', "<div id=\"tps_nav_u...");
// now caption will be "Ribau Esteves – Presidente da Câmara Municipal de Aveiro"
请记住，如果选择器与html中的任何元素都不匹配，则此函数将引发。您将不得不相应地进行处理。
答案 2 :(得分：0)
尝试：
var stringText = { “ status”：“确定”， “帖子”：{ “ id”：2335， “类别”：[ { “ id”：299， “ slug”：“ litoral-awards”， “ title”：“ Litoral Awards”， “ description”：“”， “父母”：0， “ post_count”：91 }， ]， }， “ previous_url”：“ https://litoralmagazine.com/litoral-awards14-no-canal-central/”， “ next_url”：“ https://litoralmagazine.com/premio-musica-sons-em-transito/” };
var status = stringText.status
var post = stringText.post;
var previous_url = stringText.previous_url;
var next_url = stringText.next_url;
console.log('object :', stringText.post.categories[0]);
