JavaScript将字符串拆分为具有属性的对象

Question

我遇到的问题是API给了一个长字符串,其中包含需要分解为对象的多个项目.以下是字符串的示例:

"Child 1 First Name: Ali\nChild 1 Gender: Female\nChild 1 Hair Color: Blonde\nChild 1 Hair Style: Wavy\nChild 1 Skin Tone: Tan\nChild 2 First Name: Morgan \nChild 2 Gender: Female\nChild 2 Hair Color: Brown\nChild 2 Hair Style: Ponytail\nChild 2 Skin Tone: Light\nRelationship 1 to 2: Brother\nRelationship 2 to 1: Brother\n"

它\n用于将所有内容分解为多行.该字符串是API发送的较大对象的一个​​属性.出于某种原因,当我尝试使用.split它的方法(如下面的完整代码)时,我需要使用JSON.stringify以使我的功能甚至开始工作.

这是我的完整代码:

let rawNoteData = order.customer.note;
let data = JSON.stringify(rawNoteData);

let foo = data.split("\n").reduce(function(obj, str, index) {
  let strParts = str.split(":");
  obj[strParts[0].replace(/\s+/g, '')] = strParts[1];
  return obj;
}, {});

console.log(foo);

这创建了看起来很疯狂的对象:

{'"Child1FirstName': ' Arabelle\\nChild 1 Gender' }

我认为我的功能只适用于第一个实例.我有点不确定如何解决这个问题,并清理所有疯狂的报价等等.

我的目标是将字符串拆分为一个对象,如下所示:

mongoExDoc: {
  child1FirstName: "Ali",
  child1Gender: "Female",
  child1HairColor: "Blonde",
  child1HairStyle: "Wavy",
  child1SkinTone: "Tan",
  child2FirstName: "Morgan",
  child2Gender: "Female",
  child2HairColor: "Brown",
  child2HairStyle: "Ponytail",
  child2SkinTone: "Light",
  relationship1To2: "Brother",
  relationship2To1: "Brother"
}

从那里我将把它的属性与插入到MongoDB中的另一个对象相结合.

任何帮助是极大的赞赏!

如果order.customer.note是你的示例字符串,那么这应该工作:

let data = "Child 1 First Name: Ali\nChild 1 Gender: Female\nChild 1 Hair Color: Blonde\nChild 1 Hair Style: Wavy\nChild 1 Skin Tone: Tan\nChild 2 First Name: Morgan \nChild 2 Gender: Female\nChild 2 Hair Color: Brown\nChild 2 Hair Style: Ponytail\nChild 2 Skin Tone: Light\nRelationship 1 to 2: Brother\nRelationship 2 to 1: Brother\n";
//let data = JSON.stringify(rawNoteData);  <-- Don't do this. order.customer.note is not an object.

let foo = data.split("\n").reduce(function(obj, str, index) {
  let strParts = str.split(":");
  if (strParts[0] && strParts[1]) { //<-- Make sure the key & value are not undefined
    obj[strParts[0].replace(/\s+/g, '')] = strParts[1].trim(); //<-- Get rid of extra spaces at beginning of value strings
  }
  return obj;
}, {});

console.log(foo);
