最简单的方式:
const config = require('./config.json')
console.log("name",config.name)
console.log("age",config.age)
require方法的缺点:
- 内容会被缓存,不适合动态变更的json文件
- 仅支持后缀为json的文件
稍微复杂的方法:
const fs = require('fs');
try {
const data = fs.readFileSync('./config.json', 'utf8');
// parse JSON string to JSON object
const config = JSON.parse(data);
console.log("name",config.name)
console.log("age",config.age)
} catch (err) {
console.log(`Error reading file from disk: ${err}`);
}
