Question

我正在尝试将文件上传并查看到完全私有的存储桶中。

控制器：

在控制器中，我正在Ruby V3的SDK中调用“ Aws :: S3 :: PresignedPost”函数来生成表单数据。

      @s3_direct_post = Aws::S3::PresignedPost.new(aws_config[:aws_credenciais], aws_config[:aws_bucket_region], aws_config[:aws_bucket], {
      key: "#{empresa.companyname}/ordem_servico/#{Time.now.year}/#{@ordem_servico.id}/#{@ordem_servico.os_id}_v#{@ordem_servico.versao}/#{SecureRandom.uuid}/${filename}",
      success_action_status: "201",
      acl: 'public-read',
      expires: (Time.now + 15.minutes)
      })

表格开头：

以前端的形式，我使用SDK生成的变量生成隐藏输入

      <form id="my-dropzone" action="https://bucket.s3.amazonaws.com" class="dropzone dz-clickable dz-started" enctype="multipart/form-data">
        <input type="hidden" name="key" value="nucleusteste/ordem_servico/2019/180/4_v1/49147a65-ed8b-48c9-a198-7bd6b23c72d1/${filename}">
        <input type="hidden" name="success_action_status" value="201">
        <input type="hidden" name="acl" value="public-read">
        <input type="hidden" name="Expires" value="Mon, 03 Jun 2019 17:18:54 GMT">

AWS S3 CORS：

在存储桶的设置部分中，我创建了CORS，仅接受来自我的站点的PUT，POST和DELETE，并且免费显示文件的可视化。

      <?xml version="1.0" encoding="UTF-8"?>
      <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
        <CORSRule>
          <AllowedOrigin>https://mysite.herokuapp.com</AllowedOrigin>
          <AllowedMethod>PUT</AllowedMethod>
          <AllowedMethod>POST</AllowedMethod>
          <AllowedMethod>DELETE</AllowedMethod>
          <AllowedHeader>*</AllowedHeader>
        </CORSRule>
        <CORSRule>
          <AllowedOrigin>*</AllowedOrigin>
          <AllowedMethod>GET</AllowedMethod>
        </CORSRule>
      </CORSConfiguration>

时段政策：

      {
      "Version": "2012-10-17",
      "Id": "Policy1559567062776",
      "Statement": [
      {
      "Sid": "Stmt1559567058183",
      "Effect": "Allow",
      "Principal": {
      "AWS": "*"
      },
      "Action": "s3:*",
      "Resource": "arn:aws:s3:::test...."
      }
      ]
      }

AWS用户策略：

我使用“ AmazonS3FullAccess”创建了一个AIM用户，并且还创建了以下规则并将其分配给该用户。

      {
      "Version": "2012-10-17",
      "Statement": [
      {
      "Sid": "VisualEditor0",
      "Effect": "Allow",
      "Action": [
      "s3:PutAccountPublicAccessBlock",
      "s3:GetAccountPublicAccessBlock",
      "s3:ListAllMyBuckets",
      "s3:ListJobs",
      "s3:CreateJob",
      "s3:HeadBucket"
      ],
      "Resource": "*"
      },
      {
      "Sid": "VisualEditor1",
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "arn:aws:s3:::*"
      },
      {
      "Sid": "VisualEditor2",
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "arn:aws:s3:::*/*"
      }
      ]
      }

返回总是相同的：

      <?xml version="1.0" encoding="UTF-8"?>
      <Error><Code>AccessDenied</Code><Message>Access Denied</Message>
        <RequestId>2EBDDD1ED051EB93</RequestId>
        <HostId>jULDSNHGX7L8W67duCAwdUjssSBp6eSuYlQR4xlfwTovOaMCkLAOUSJhM9g4o1w1WdSWAZfn+vg=</HostId>
      </Error>
