本文介绍了一个使用Node.js的fs模块来检查指定路径是否为有效目录的方法。通过调用fs.statSync()函数并判断返回结果是否为目录来实现。此外，还处理了文件不存在的情况以及其他可能的异常。
function checkDirExist(path)
{
try {
return fs.statSync(path).isDirectory();
}
catch (e) {
if (e.code == 'ENOENT') { // no such file or directory. File really does not exist
console.log("File does not exist.");
return false;
}
console.log("Exception fs.statSync (" + path + "): " + e);
throw e; // something else went wrong, we don't have rights, ...
}
}
try {
return fs.statSync(path).isDirectory();
}
catch (e) {
if (e.code == 'ENOENT') { // no such file or directory. File really does not exist
console.log("File does not exist.");
return false;
}
console.log("Exception fs.statSync (" + path + "): " + e);
throw e; // something else went wrong, we don't have rights, ...
}
}
