所以我想将大文件上传到远程,所以我正在创建ReadStream
const stream = fs.createReadStream(req.file.path);
async uploadStream(stream: NodeJS.ReadableStream, filePath: string) {
const dir = path.dirname(filePath);
if (!(await this.exists(dir))) {
await this.mkdir(dir);
}
await this.putStream(stream, filePath);
return this.url(filePath);
}
async putStream(stream: NodeJS.ReadableStream, filePath: string) {
await this.connect();
const normFIlePath = this.normalizePath(filePath);
await this.sftp.put(stream, normFIlePath).catch(e => {
console.log(e);
});
await this.disconnect()
}
上传后,我正在将数据保存到数据库并重现文件url
file = await fileRepo.save(file);
res.send({
id: file.data.itemId,
src: file.url
});
文件正在上传,但是之后返回错误:
(node:18) UnhandledPromiseRejectionWarning: Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client
