nodejs statSync判断一个目录或文件是否存在

获取目录下某个文件中的信息 [ { name, photoUrl, ...}, ]
目录： 项目名称/app/public/json_tb/user_1/blog_1/commiter_2.json

getCommitForCurBlog (blogId, authorId, committerId) {
        let curPath = '/user_' + authorId + '/blog_' + blogId + '/committer_' + committerId + '.json'
        let url = './app/public/json_tb' + curPath
        let jsonData = []
        // console.log('fs.statSync(url):', path.resolve(url))
        // console.log('fs.statSync(url):', fs.statSync(path.resolve(url)) )
        try {
            let statObx = fs.statSync(path.resolve(url))
            // console.log('isFile(): ', statObx.isFile(), statObx.isDirectory())
            if (statObx.isFile()) {
                jsonData = require('@app/public/json_tb' + curPath)
                // console.log('>>>>>>>>>')
            }
        } catch (e) {
            // nodejs.ENOENTError: ENOENT: no such file or directory
        }
        // console.log('>>>>>>>>>', jsonData)
        return jsonData
