Javascript中对象的自定义属性映射

我能在POST请求中发送元数据吗？我能够在POST请求中发送大量数据，但如果需要在POST方法中将数据分组并发送到RESTAPI，我是否必须在主体中操纵值

我可以这样发送：

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

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"
} 

{
"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"}
}

但我需要发送如下数据：

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

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"
} 

{
"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"}
}

如果要从当前元数据对象创建新对象，可以按如下方式初始化新对象：

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

然后可以使用

Object.keys（）

在对象键上循环，并弹出结果对象：

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：

{
"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"
} 

{
"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"}
}

var obj={
“名称”：“puppetlabs ntp”，
“版本”：“6.1.0”，
“作者”：“木偶公司”，
“摘要”：“安装、配置和管理NTP服务。”，
“许可证”：“Apache-2.0”，
“来源”：https://github.com/puppetlabs/puppetlabs-ntp",
“项目页面”：https://github.com/puppetlabs/puppetlabs-ntp",
“问题\u url”：https://tickets.puppetlabs.com/browse/MODULES"
};
var res={
用户：{}，
项目：{}
};
Object.keys（obj）.forEach（函数（key）{
if（key==“name”| | key==“version”| | key==“author”）
res.User[key]=obj[key]；
其他的
res.Project[key]=obj[key]；
});
控制台日志（res）您是否尝试发送如上所示的数据？你犯了什么错误？我不认为上面的逻辑上有什么不同。如果您按照
http
库的要求将其作为
数据
传递，那么它应该能够处理它。最简单的方法是编写自定义映射器函数。然而，我不知道这与React或REST有什么关系：DJust
JSON.stringify（元数据）
，然后在控制器（服务器）中
JSON.parse（req.body.metadata）
？
