javascript - Javascript中对象的自定义属性映射

Question

我能否在 POST 请求中发送元数据？我可以在 POST 请求中发送大量数据，但如果需要在 POST 方法中将数据组合在一起并将其发送到 REST API，我是否必须在正文中操作值？

我可以这样发送:

示例:

{
"name": "puppetlabs-ntp",
  "version": "6.1.0",
  "author": "Puppet Inc",
  "summary": "Installs, configures, and manages the NTP service.",
  "license": "Apache-2.0",
  "source": "https://github.com/puppetlabs/puppetlabs-ntp",
  "project_page": "https://github.com/puppetlabs/puppetlabs-ntp",
  "issues_url": "https://tickets.puppetlabs.com/browse/MODULES"
} 

但是我需要像这样发送数据:

示例:

{
"User":{"name": "puppetlabs-ntp",
  "version": "6.1.0",
  "author": "Puppet Inc"},``
"Project":{
  "summary": "Installs, configures, and manages the NTP service.",
  "license": "Apache-2.0",
  "source": "https://github.com/puppetlabs/puppetlabs-ntp",
  "project_page": "https://github.com/puppetlabs/puppetlabs-ntp",
  "issues_url": "https://tickets.puppetlabs.com/browse/MODULES"}
}

如果你想从你当前的元数据对象创建一个新对象，你可以像这样初始化你的新对象:

var res = {
  User: {},
  Project: {}
};

然后您可以使用 Object.keys() 遍历对象键，并填充结果对象:

Object.keys(obj).forEach(function(key) {
  if (key === "name" || key === "version" || key === "author")
    res.User[key] = obj[key];
  else
    res.Project[key] = obj[key];
});

演示:

var obj = {
  "name": "puppetlabs-ntp",
  "version": "6.1.0",
  "author": "Puppet Inc",
  "summary": "Installs, configures, and manages the NTP service.",
  "license": "Apache-2.0",
  "source": "https://github.com/puppetlabs/puppetlabs-ntp",
  "project_page": "https://github.com/puppetlabs/puppetlabs-ntp",
  "issues_url": "https://tickets.puppetlabs.com/browse/MODULES"
};

var res = {
  User: {},
  Project: {}
};
Object.keys(obj).forEach(function(key) {
  if (key === "name" || key === "version" || key === "author")
    res.User[key] = obj[key];
  else
    res.Project[key] = obj[key];
});
console.log(res);
