如何从Ruby中访问Office 365 API? [英] How to hit Office 365 API from Ruby?

问题描述

我正在尝试从Ruby on Rails后端访问Office 365 API，并且遇到问题.

I am attempting to access the Office 365 API from a Ruby on Rails backend and am having problems.

我是否使用ruby_outlook gem( github)或关注Microsoft的

Whether I use the ruby_outlook gem (github) or follow Microsoft's official Ruby on Rails sample, I am getting 401 unauthorized.

我的access_token正在使用Omniauth保存，并且有效，我通过将其粘贴到此处中进行了检查.

My access_token is being saved using Omniauth and is valid, I checked by pasting it in here.

我使用正确的access_token吗?它的长度超过1400个字符(准确地说是1442个字符).谁能给我看一个如何从Ruby正确调用Office 365邮件API的示例吗?

Am I using the correct access_token? It is over 1400 characters long (1442 to be exact). Can anyone show me an example of how to properly call the Office 365 Mail API from Ruby?

代码示例(使用法拉第):

Code Example (using Faraday):

key = @auth[:key]

 conn = Faraday.new(:url => 'https://outlook.office.com') do |faraday|
   # Outputs to the console
   faraday.response :logger
   # Uses the default Net::HTTP adapter
   faraday.adapter  Faraday.default_adapter  
 end

 response = conn.get do |request|
   request.url '/api/v2.0/me/contacts'
   request.headers['Authorization'] = "Bearer #{key}"
   request.headers['Accept'] = 'application/json'
 end

代码示例(使用ruby_outlook gem):

Code Example (using ruby_outlook gem):

client = RubyOutlook::Client.new

key = @auth[:key]

page = 1
view_size = 30
fields = [
  'DisplayName',
  'EmailAddresses'
]
sort = {:sort_field => 'DisplayName', :sort_order => 'ASC'}
contacts = client.get_contacts key, view_size, page, fields, sort

ruby_outlook gem返回的确切错误是:

The exact error that the ruby_outlook gem returns is:

{"ruby_outlook_error"=>401}

推荐答案

问题是令牌中的作用域与所使用的API端点之间不匹配.范围必须与端点匹配.

The problem is a mismatch between the scopes in your token and the API endpoint you're using. The scope has to match the endpoint.

在您的情况下，您请求了图形API 范围，但您正在调用 Outlook API 端点.

In your case, you requested a Graph API scope, but you're calling the Outlook API endpoint.

您只需要在一个位置注册客户ID和密码: https://apps.dev. microsoft.com .听起来您可能还已经在Azure管理门户中注册了一个应用程序(要求您在注册本身中指定作用域).

You should only have to register in one place for your client ID and secret: https://apps.dev.microsoft.com. It sounds like you may have also registered an app in the Azure Management Portal (which requires you to specify scopes in the registration itself).

确保您使用的是来自apps.dev.microsoft.com的客户端ID，并确保您的范围要求为" https://outlook.office.com 的范围，您应该会很高兴.

Make sure you're using a client ID from apps.dev.microsoft.com and make sure your scopes are requested as 'https://outlook.office.com' scopes, and you should be good to go.

如果Omniauth策略依赖于Azure的v1身份验证终结点，则可能需要您在Azure管理门户中进行注册.在这种情况下，请忘记我对apps.dev.microsoft.com所说的内容，而是更改您的应用程序注册以使用Microsoft Exchange Online的适当权限.

That Omniauth strategy might require that you register in the Azure Management Portal if they are dependent on Azure's v1 auth endpoints. In that case, forget what I said about apps.dev.microsoft.com and instead change your app registration to use the appropriate permissions from Microsoft Exchange Online.

更新:根据您的评论，Omniauth策略确实需要v1 Azure身份验证/令牌终结点，因此，如果要继续使用该策略，则有2个选择:

UPDATE: Based on your comments, that Omniauth strategy DOES require the v1 Azure auth/token endpoints, so you have 2 options if you want to keep using that strategy:

• 更改代码以使用Graph端点.您需要使用上面的Faraday选项(ruby_outlook是为Outlook端点设计的)，并将URL更改为https://graph.microsoft.com，将request.url更改为/v1.0/me/contacts.
• 在 https://dev.outlook.com/appregistration 上创建新的应用注册，为您的代码创建适当的范围.您需要一个Office 365帐户才能登录到应用程序注册工具.

• Change your code to use the Graph endpoints. You'll need to use the Faraday option above (ruby_outlook is designed for the Outlook endpoints), and change your URL to https://graph.microsoft.com, and the request.url to /v1.0/me/contacts.
• Create a new app registration at https://dev.outlook.com/appregistration, which will create the proper scopes for your code. You'll need an Office 365 account to login to the app registration tool.
