输出是 {"设备":2049,"模式":33204" NLINK":1," UID":1000," GID& #34;:1000," RDEV":0," BLKSIZE":4096,"鲍":6578368,"大小":0, "块":0,"的atime":" 2016-07-18T02:46:12.845Z""修改时间":&#34 ; 2016-07-18T02:46:12.845Z""的ctime":" 2016-07-18T02:46:12.845Z"" birthtime" :" 2016-07-18T02:46:12.845Z"}
为什么文件大小为0,我检查文件大小:
console.log(fs.statSync(filePath));
{dev:2049, 模式:33204, nlink:1, uid:1000, gid:1000, rdev:0, blksize:4096, ino:1975657, 大小:1964074, 街区:3840, atime:2016-07-18T02:29:16.977Z, mtime:2016-07-18T02:28:30.037Z, ctime:2016-07-18T02:28:30.037Z, 出生时间:2016-07-18T02:28:30.037Z}
答案 0 :(得分:1)
也许,您在流写入文件时调用console.log
。尝试在finish
上添加侦听器。
var stream = fs.createWriteStream(filePath);
stream.on('finish', function () {
console.log(fs.statSync(filePath));
});
superagent
...
.pipe(stream);
