我有一个代码,我在其中创建一个新目录。但问题是回调会在创建目录时更早调用。这个方法在类中。如何等待文件创建然后调用回调?我需要async / await,但我不知道如何包装它。任何解决方案?
createMissingPath(newFilePathname, callback) {
try {
let currentIndex = 0;
while ((currentIndex = newFilePathname.indexOf('/'/*path.sep*/, currentIndex+1))!= -1) {
let lastPath = newFilePathname.substr(0, currentIndex);
if(!fs.existsSync(lastPath)) {
logger.info('Trying to create directory: %s', lastPath);
fs.mkdir(lastPath);
}
}
callback(null, null);
}
catch (exception) {
logger.error('Caught exception : %s', inspect(exception));
callback(exception, null);
}
}
