如何将对象的结构操作为“点表示法”样式的数组

Question

我正在使用 Meteor 开发一个项目，该项目使用 Mongoose（使用 Meteor.HTTP）连接到外部 API。我有嵌套对象，其源数据如下所示：

{name: "asdasd", active: true, status: Object, domain: "asdas", category: "1"…}

我需要以这种格式 POST/PUT 数据：

{
  active: true,
  category: "1",
  contact.companyName: "asd",
  contact.email: "asd",
  contact.managerName: "asd",
  contact.phone: "asd",
  domain: "asdasd",
  name: "asjdnas",
  ImagePaths: ["asdasdad","asdasdAsd"],
}

没有嵌套样式对象，或任何类型的：

ImagePaths[0] : asdasdad,
ImagePaths[1] : asdasdad

sites: 
   0: "565f1c7da35dcaa718713f4f"

等等。我找到了这段代码（@rhalff）

var dotize = dotize || {};

dotize.parse = function(jsonobj, prefix) {
  var newobj = {};
  function recurse(o, p) {
    for (var f in o)
    {
      var pre = (p === undefined ? '' : p + ".");
      if (o[f] && typeof o[f] === "object"){
        newobj = recurse(o[f], pre + f);
      } else {
        newobj[pre + f] = o[f];
      }
    }
    return newobj;
  }
  return recurse(jsonobj, prefix);
};

但我仍然遇到数组问题。它们看起来像这样：

  Paths.0: "asdkmalksmdasd",
  Paths.1: "asdasdad",

我需要的是这个：

Paths:["asdkmalksmdasd","asdasdad"];

你可以在jsbin上玩：https://jsbin.com/kadivewoti/edit?js,console

我怎样才能做到这一点？

Answer 1

我在代码中添加了一个if-statement：

var dotize = dotize || {};

dotize.parse = function(jsonobj, prefix) {
  var newobj = {};
  function recurse(o, p) {
    for (var f in o)
    {
      var pre = (p === undefined ? '' : p + ".");
      if(o[f] && o[f].length){
        newobj[f] = o[f];
      }
      else if (o[f] && typeof o[f] === "object"){
        newobj = recurse(o[f], pre + f);
      } 
      else {
        newobj[pre + f] = o[f];
      }
    }
    return newobj;
  }
  return recurse(jsonobj, prefix);
};

var mydata = '{"name":"asjdnas","active":true,"status":{"pending":true,"comment":"asdasd"},"domain":"asdasd","category":"1","contact":{"companyName":"asd","managerName":"asd","phone":"asd","email":"asd"},"server":{"os":"akjsdn"},"Paths":["asdkmalksmdasd","asdasdad"]}';


mydata = JSON.parse(mydata);
mydata = dotize.parse(mydata);
console.log(mydata);

即

if(o[f] && o[f].length){
    newobj[f] = o[f];
}
