Answer 1

假设您的 JSON 被分配给一个名为 response 的变量，您可以通过以下方式访问 body：
let body = response.data.data[0].body

并且标题带有
let title = response.data.data[0].title

如果您想遍历数据数组以获取所有条目（例如标题）的值，请尝试以下操作：
let titles = response.data.data.forEach(entry => console.log(entry.title));

Answer 2

假设 json 存储在变量 res.

中

由于第二个数据对象存储为数组[].

title = res['data']['data'][0]['title'];
body = res['data']['data'][0]['body'];

如果你发现数组中有多个对象，那么你将不得不将0更改为数组中对象的索引。参考：www.json.org
