node.js - Docker 中 Apollo 服务器上传文件失败

Question

UPD 几个小时后，我有了一个好主意，在 docker 中尝试另一个 Node 版本。 Alpine 给出了这个错误，而 10.15 工作正常。

我的解析器中有以下函数来通过 apollo graphql 上传文件

return new Promise(function(resolve, reject) {
const { createReadStream, filename, mimetype } = file
if (!(mimetype === 'image/png' || mimetype === 'image/jpeg' || mimetype === 'image/jpg')){
  const error = new Error('Forbidden file type ', mimetype)
  error.code = 415
  reject(error)
}

const savedFileName = uuidv4()+path.extname(filename)
const savedFile = path.join(__dirname, '..', 'images', subDir, savedFileName)
const imagePath = path.join('/images', subDir, savedFileName).replace(/\\/g, "/")

const readStream  = createReadStream()

const writeStream = fs.createWriteStream(savedFile, { flags : 'w' });
readStream.pipe(writeStream)

readStream.on('error', () => console.log('reading error'))
writeStream.on('finish', () => resolve({file: savedFile, imageUrl: imagePath}))
writeStream.on('error', (error) => {

  //const err = new Error('Error writing file')
  //error.code = 422
  reject(error)
})

在我的Windows开发环境中运行良好。我尝试为我的项目创建 docker 容器，但此代码段失败并出现错误:

我是 Docker 新手，特别是 Linux 新手。也许 Linux 中的读取和管道处理方式有所不同。但我不明白该去哪里看。是Apollo的问题还是docker的问题还是我的linux知识贫乏的问题。将不胜感激任何建议。

这是由于 Node 弃用了一些内部流 API，请参阅 DEP0135: WriteStream.open() and ReadStream.open() are internal .

WriteStream.open() and ReadStream.open() are undocumented internal APIs that do not make sense to use in userland. File streams should always be opened through their corresponding factory methods fs.createWriteStream() and fs.createReadStream()) or by passing a file descriptor in options.

有一个问题需要尝试解决所有问题:Upgrade graphql-upload to 9.0 to support Node.JS 13 。关键是fs-capacitor已更新以解决此问题，但依赖于它的所有内容都需要相应更新。

目前，您需要使用 Node 12 或至少使用 13 之前的版本。
