使用 Uppy trough Shrine return 405 Method Not Allowed 上传图片

Question

我正在尝试使用 Ruby On Rails 作为我的后端，以及像 ReactOnRails 和 Shrine 这样的宝石，此外，我使用包 Uppy 将图像上传到 AWS S3

到目前为止一切正常，直到我尝试通过 Uppy 上传图像，这应该通过后端传输 AWS 凭证，所以我不会从前端公开我的密钥。

React 组件片段

.use(AwsS3, {
  limit: 5,
  // serverUrl: 'https://uppy-companion.my-app.com/',
  strings: {
    preparingUpload: 'Preparing upload...'
  },
  getUploadParameters(file) {
    return fetch('/presign?filename=' + file.name, {
      method: 'post',
      // Send and receive JSON.
      headers: {
        accept: 'application/json',
        'content-type': 'application/json'
      },
      body: JSON.stringify({
        filename: file.name,
        contentType: file.type
      })
    }).then((response) => {
      // Parse the JSON response.
      return response.json()
    }).then((data) => {
      // Return an object in the correct shape.
      return {
        method: data.method,
        url: data.url,
        fields: data.fields
      }
    }).catch((error) => console.log(error))
  }
});

我的路线是

mount Shrine.presign_endpoint(:cache) => '/presign'

最后是我的 shrine.rb 文件

require 'shrine'

if Rails.env.production?
  require 'shrine/storage/s3'

  s3_options = {
    access_key_id: Rails.application.credentials.aws[:s3_access_key_id],
    secret_access_key: Rails.application.credentials.aws[:s3_secret_access_key],
    region: Rails.application.credentials.aws[:s3_region],
    bucket: Rails.application.credentials.aws[:s3_bucket]
  }

  Shrine.storages = {
    cache: Shrine::Storage::S3.new(prefix: 'cache', **s3_options),
    store: Shrine::Storage::S3.new(prefix: "store", **s3_options)
  }
else
  require 'shrine/storage/file_system'

  Shrine.storages = {
    cache: Shrine::Storage::FileSystem.new('public', prefix: 'uploads/cache'),
    store: Shrine::Storage::FileSystem.new('public', prefix: 'uploads')
  }
end

Shrine.plugin :activerecord

Shrine.plugin :logging
Shrine.plugin :determine_mime_type
Shrine.plugin :cached_attachment_data
Shrine.plugin :restore_cached_data
#TODO: docs
Shrine.plugin :presign_endpoint if Rails.env.production?
Shrine.plugin :upload_endpoint if !Rails.env.production?

Shrine::Attacher.promote { |data| PromoteJob.perform_async(data) }
Shrine::Attacher.delete { |data| DeleteJob.perform_async(data) }

我的 AWS S3 Cros 配置

当我通过 uppy.js 上传文件时，我不知道如何解决这个问题。

Answer 1

Shrine 的预签名端点响应 GET 请求，而不是 POST，因此您需要做

getUploadParameters(file) {
  return fetch('/presign?filename=' + file.name, {
    method: 'get',
    ...

顺便说一下，如果你在 /s3/params 上安装预签名端点：

Rails.application.routes.draw do
  mount Shrine.presign_endpoint(:cache) => "/s3/params"
end

您不需要任何这种 fetch() 逻辑，您只需将 Uppy 指向您的应用程序，它就会自动使用 /s3/params 并为您完成所有的抓取工作：

uppy.use(AwsS3, {
  companionUrl: '/',
  ...
})
