Postgresql Heroku Postgres:AWS s3预签名URL不工作

我犯了6个小时的错误，快发疯了

我已经使用CLI创建了一个heroku应用程序，并成功地推送了git，但是在应用程序运行之前，我需要使用

db.create_all（）

初始化一组表，但是我的本地主机postgres中有6gb的数据，我希望迁移到heroku以供使用

以通常的方式实例化表（create_all）将不起作用，因为索引页需要表中的某些内容，因此我的表必须预先填充所述localhost数据才能起作用

我完全按照这里的文档操作，导出了我的.dump文件并将其上载到我的bucket：

公共共享已启用，我已使用

setx

命令在AWS CLI中设置

ACCESS\u KEY\u ID

和

SECRET\u ACCESS\u KEY

。我还设置了heroku配置：set AWS_ACCESS_KEY_ID=matching_AWS_cli_blah AWS_SECRET_ACCESS_KEY=matching_AWS_cli blah

然后使用命令

aws s3 presign s3\u url

我复制了输出（我将添加与我使用的aws文档不同的外观）

我的外观示例（随机更改一些数字）

https://mybucketname.s3.eu-west-2.amazonaws.com/mydb.dump?X-Amz算法=AWS4-HMAC-SHA256&X-Amz-Credential=LLLLL 4C7LLLLLLLNLLQ%2Fnnnn08%2Feu-west-2%2Fs3%2Faws4\u请求&X-Amz-Date=20201208T004613Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=LL9D80NNC457EA838FDNN4A25B0C9LL066F54FF8ACF42AFNNNA8877该文档提供了一个整洁的AWSAccessKeyId=变量

我只有一个bucket，并且
阻止公共访问（bucket设置）
设置为OFF，文件本身可以公开共享。对象URL初始化下载罚款，包括匿名

使用以下命令时（根据heroku文档）

heroku pg:备份：还原'https://mybucketname.s3.eu-west-2.amazonaws.com/mydb.dump?X-Amz算法=AWS4-HMAC-SHA256&X-Amz-Credential=LLLLL 4C7LLLLLLLNLLQ%2Fnnnn08%2Feu-west-2%2Fs3%2Faws4_请求&X-Amz-Date=20201208T004613Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=LL9D80NNC457EA83298FDNN4A25B0C9LL066F54FF8ACF42DNNA8877'数据库\u URL

我得到以下输出到终端

有人能指出我哪里出错了吗

无论何时在命令行上使用预签名URL，都需要引用它们。它们包含对shell有意义的结构，如

。因此，通常您应该将预签名URL用双引号括起来。每当您在命令行上使用预签名URL时，您都需要将它们引起来。它们包含对shell有意义的结构，如
