问题描述
我试图按照从iOS应用程序上传文件到Amazon S3的步骤。
I am trying to follow the steps to upload files to Amazon S3 from an iOS app.
据AWS的iOS的SDK文档，上传前，需要进行身份验证的应用程序，用户通过我的后端服务器的安全访问AWS资源：的
According to the AWS iOS SDK docs, before uploading, it is required to authenticate the app users for secure access to AWS resources via my backend server:http://docs.aws.amazon.com/mobile/sdkforios/developerguide/cognito-auth.html#providing-creds
什么是正确的方式来调用AWS Cognito身份 GetOpenIdTokenForDeveloperIdentity 从轨服务（4.1版）服务器？
What is the right way to call the AWS Cognito Identity GetOpenIdTokenForDeveloperIdentity service from a rails (version 4.1) server?
这个服务是不是AWS-SDK宝石的一部分。
This service is not part of the aws-sdk gem.
推荐答案
Cognito仅通过在 V2的Ruby支持SDK 。
Cognito is only supported via the the v2 Ruby SDK.
下面是一个使用V2 SDK一个小例子为 GetOpenIdTokenForDeveloperIdentity ：
Here is a minimal example for GetOpenIdTokenForDeveloperIdentity using the v2 SDK:
require 'aws-sdk'
cognito = Aws::CognitoIdentity::Client.new(region:'us-east-1')
resp = cognito.get_open_id_token_for_developer_identity(
identity_pool_id: 'IDENTITY_POOL_ID',
logins: {'MY_PROVIDER_NAME' => 'USER_IDENTIFIER'})
- IDENTITY_POOL_ID - 池的ID
- MY_PROVIDER_NAME - 你对你的身份池中配置的提供者的名称
- USER_IDENTIFIER - 该用户在系统中的唯一标识符
- IDENTITY_POOL_ID - The ID of your pool
- MY_PROVIDER_NAME - The provider name you configured on your identity pool
- USER_IDENTIFIER - The unique identifier for this user in your system
响应（成功时）将包含 identity_id 和标记为您的用户，可以通过回为您的移动应用程序。
The response (when successful) will contain an identity_id and token for your user, which can be passed back to your mobile application.
