使用以下脚本时，我可以通过 Chrome 开发工具控制台看到该 API 返回各种部分，例如 object、orbit、phys_param、signature 和 proto。我想获取 object、orbit 和 phys_param 部分中提供的数据，并将它们推断到 HTML 表中。在此表中，我希望获得这些部分的特定数据的子集。例如，我想创建一个表，其中包含对象部分中存在的全名变量、轨道部分中存在的平均运动变量以及 phys_param 部分中的直径变量。我还注意到一些数据位于键值列表内，该列表本身是另一个列表的元素。如何访问返回列表中的这些特定数据部分？
fetch('https://ssd-api.jpl.nasa.gov/sbdb.api?spk=2000001&phys-par=1')
.then(response => response.json()) .
then(data => { console.log(data) })
您可以使用 JSON.stringify() 的“美化”版本，如下所示
JSON.stringify(d,null,2)
创建人类可读的数据版本。然后你可以像这样构建表格：
