json - Node fs.writeFileSync 错误

Question

我目前正在学习 Node.JS 类(class)，我们正在使用 fs.writeFileSync() 通过终端读取、写入、保存和编辑用户的输入数据。它对于几句话长的文本效果很好，但对于任何更大的文本， Node 终端 (>) 开始运行，而不是运行代码。

我对 Node.js 有基本的了解，但不明白为什么这种情况不断发生。 非常感谢任何帮助。谢谢。

下面的代码，

const fs = require('fs');

var originalNote = {
    title: process.argv[2],
    body: process.argv[3],
};

var originalNoteString = JSON.stringify(originalNote);

fs.writeFileSync('Notes.json', originalNoteString);

var noteString = fs.readFileSync('Notes.json');

var Note = JSON.parse(noteString);

console.log(typeof (Note));
console.log(originalNoteString);
console.log(Note.title);

• 终端输出1-

Viveks-MacBook-Pro:playground Vivek$ node JSON.js 'Lorem Ipsum' 'ldfdfefnhebfhbfhrbfherbfhrbfhrefocalStorage fefef fede'

object

{"title":"Lorem Ipsum","body":"ldfdfefnhebfhbfhrbfherbfhrbfhrefocalStorage fefef fede"}

• 终端输出2-

Viveks-MacBook-Pro:playground Vivek$ node JSON.js 'Lorem Ipsum' 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a typespecimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum'

'>'

Answer 1

基本问题在于第二个参数中发送的数据。

如果您查看数据，就会发现其中包含industry's一词，其中包含单引号。

这导致第二个参数被截断。

如果您将第二个参数放在双引号中，您的代码应该可以正常工作。

如果可能的话，您还可以使用转义字符来忽略数据中的单引号。

我希望这有帮助:)
