如何将一串文本消息解析为一个对象

Question

我想将模板字符串中包含的文本消息解析为以下 JS 对象。每条短信都由一个新行分隔，在作者姓名之后有一个冒号。消息的内容还可以包括新行、方括号和冒号。您首选的解决方法是什么？

let string = `[03.12.21, 16:12:52] John Doe: Two questions:
How are you? And is lunch at 7 fine?
[03.12.21, 16:14:30] Jane Doe: Im fine. 7 sounds good.`;

let data = {
  "03.12.21, 16:12:52": {
    "author": "John Doe",
    "content": "Two questions:\nHow are you? And is lunch at 7 fine?"
  },
  "03.12.21, 16:14:30": {
    "author": "John Doe",
    "content": "Im fine. 7 sounds good."
  },
}; // will be parseString()

function parseString() {
  // ?
}

Answer 1

我会将整个字符串分成小块，例如：令字符串 = 日期 + 作者 + 内容。这样就简单多了。或者使用类似 string.split()

Answer 2

像这样？

let string = `[03.12.21, 16:12:52] John Doe: Two questions:
How are you? And is lunch at 7 fine?
[03.12.21, 16:14:30] Jane Doe: Im fine. 7 sounds good.`;

let chunks = string.split(/^\[(\d\d\.\d\d\.\d\d, \d\d\:\d\d\:\d\d)\](.*?):/m);

let data = {};
for (let i = 3; i < chunks.length; i += 3) {
  const date = chunks[i - 2];
  const author = chunks[i - 1].trim();
  const content = chunks[i].trim();
  data[date] = {
    author,
    content,
  };
}

console.log(data);

.as-console-wrapper{top:0;max-height:100%!important}

Answer 3

是这样的吗？

function parseMessage(message) {
   var messageObj = {};
   var messageArray = message.split(" ");
   messageObj.command = messageArray[0];
   messageObj.args = messageArray.slice(1);
   return messageObj;
}
