OVH对象存储，当我尝试上传大文件(超过100 Ko)时，什么也没有发生 [英] OVH Object Storage, nothing happens when I try to upload large file (more than 100 Ko)

问题描述

我尝试用OVH对象存储上传文件. 但是根据文件繁重，我有三种不同的行为.

I try to upload files with OVH object storage. But I have three different behavior according to the heavy file.

• 具有小于100Ko的重量文件，一切正常

• With a weight file which less than 100Ko, everything is ok

对于重量超过100Ko的重量文件，出现以下错误:Error: write after end，但是该文件已上传到ovh对象存储中

With a weight file which more than 100Ko, I have this error: Error: write after end, but the file is uploaded on ovh object storage

对于重量超过250Ko的重量文件，什么也不会发生，并且不会上传该文件. fs ReadStream已打开，但是通过管道传输(与读取流一起)的写入流未完成.

With a weight file which more than 250Ko, nothing happens, and the file is not uploaded. The fs ReadStream is open, but the write stream piped (with the read stream) not finish.

这是我的代码:

  var client = require('pkgcloud').storage.createClient({
    provider: 'openstack',
    username: myusername,
    password: mypassword,
    region: 'GRA',
    authUrl: 'https://auth.cloud.ovh.net/'
  });

  const fsReadStream = fs.createReadStream(path.resolve(__dirname, fileLocation))

  let writeStream = client.upload({
    container: myOvhStorageContainer,
    remote: 'fileName.jpg',
  });

  writeStream.on('error', function (err) {

    console.log(err)
  });

  writeStream.on('success', async function (file) {
    console.log(file)
  });

  fsReadStream.on('open', function () {
    console.log('open!!')

    fsReadStream.pipe(writeStream);
  });

推荐答案

问题来自 pkgcloud 中的错误，该错误在于它如何为OpenStack Storage流文件.

The problem comes from a bug in pkgcloud in how it streams files for OpenStack Storage.

在 https://github.com中公开了解决方案，并提出了修复程序. /pkgcloud/pkgcloud/pull/673

有 pkgcloud 的分支包含建议的修补程序，可以在等待正式接受该修补程序的同时使用它们:

There are forks of pkgcloud that include the proposed fix, and they can be used while waiting for the fix to be officially accepted:

• https://github.com/madarche/pkgcloud/
• https://github.com/StartupFlow/pkgcloud/tree/fix_write_after_end

• https://github.com/madarche/pkgcloud/
• https://github.com/StartupFlow/pkgcloud/tree/fix_write_after_end

要在项目/应用程序中使用这样的存储库，请编辑package.json来修改dependencies，如下所示:

To use such a repository in your project/application, edit your package.json to modify the dependencies like this:

"dependencies": {
    …
    "pkgcloud": "https://github.com/madarche/pkgcloud.git#fe2701eb6eb984e3d067d5df7610ca0751528dbd",
    …
  },

您还可以简单地创建自己的pkgclould分支，因此您不必信任随机的Git存储库.

You can also simply create your own fork of pkgclould, so you don't have to trust a random Git repository.
