Node.js“请求”;未处理的错误,节点:事件:368
我遇到了一个重复出现的错误,导致我的程序崩溃。 在程序中,我一直在发出异步请求(我应该说是一一请求) 要从互联网上下载特定图像,这是我的请求代码:
const urlDownload = (uri, filename, callback) => {
try {
console.log('start url');
console.log(uri);
request.head(uri, function(err, res, body){
if(err) {
console.log('request error!');
console.log(err);
} else {
request(uri).pipe(fs.createWriteStream(filename)).on('close', callback);
console.log('end url');
}
// console.log('content-type:', res.headers['content-type']);
// console.log('content-length:', res.headers['content-length']);
});
} catch(e) {
console.log('urlDownload issue');
console.log(e);
}
}
现在,有时它不会崩溃,但我觉得 50% 或更多的时间它会出现这个确切的错误:
node:events:368
throw er; // Unhandled 'error' event
^
Error: aborted

at emitErrorCloseNT (node:internal/streams/destroy:122:3)
at processTicksAndRejections (node:internal/process/task_queues:83:21) {
code: 'ECONNRESET'
}
我不知道该怎么办做了,试图搜索它并没有发现什么, 它尝试下载的 URL 也没有问题!
根据我所做的控制台日志,我认为它在成功结束请求过程后似乎崩溃了,因为我确实得到了输出,然后它崩溃了,这只是猜测,我不知道发生了什么。
I'm getting a reoccuring error that crashes my program.
In the program, I'm consistantly making async requests (one by one I should say)
to download specific images off the internet, this is my code for the request:
const urlDownload = (uri, filename, callback) => {
try {
console.log('start url');
console.log(uri);
request.head(uri, function(err, res, body){
if(err) {
console.log('request error!');
console.log(err);
} else {
request(uri).pipe(fs.createWriteStream(filename)).on('close', callback);
console.log('end url');
}
// console.log('content-type:', res.headers['content-type']);
// console.log('content-length:', res.headers['content-length']);
});
} catch(e) {
console.log('urlDownload issue');
console.log(e);
}
}
Now, sometimes it doesn't crash, but I feel like 50% or more of the times it does with this exact error:
node:events:368
throw er; // Unhandled 'error' event
^
Error: aborted
at connResetException (node:internal/errors:691:14)
at TLSSocket.socketCloseListener (node:_http_client:407:19)

at emitErrorCloseNT (node:internal/streams/destroy:122:3)
at processTicksAndRejections (node:internal/process/task_queues:83:21) {
code: 'ECONNRESET'
}
I don't know what to do, tried to search about it and found nothing really,
nothing wrong with the URL it tries to download too!
based on the console logs I have made, it seems like it crashes AFTER it ends the request process successfully I think, because I do get the output, and then it crashes, that's just speculations, I have no idea what's going on.
