javascript - 使用反斜杠转义双引号

Question

我有一个对象:

const ratingSettings = {performer: true, chiefEngineer: true, engineer: true, customer: true}

我想将其转换为 GraphQL 字符串，类似于用反斜杠转义所有双引号:

"{\"performer\":true,\"chiefEngineer\":true,\"engineer\":true,\"customer\":true}"

我尝试了以下方法:

const ratingSettings = JSON.stringify({performer: true, chiefEngineer: true, engineer: true, customer: true})

const getMutationObject = data => Object.keys(data).map(key => `${key}: "${data[key]}"`).join(' ')

const userData = getMutationObject(ratingSettings);

但我得到的并不完全是我需要的:

"{"performer":true,"chiefEngineer":true,"engineer":true,"customer":true}"

我需要用\转义所有双引号

提前感谢您提供的解决方案!

JSON.stringify 对象，然后使用 .replace 将所有 " 替换为 \\" :

const ratingSettings = {performer: true, chiefEngineer: true, engineer: true, customer: true}
const escapedJSON = JSON.stringify(ratingSettings)
  .replace(/"/g, '\\"');
console.log(escapedJSON);
