Oauth2

[zzk]

Implement oauth2 token based authorization into ruby_odata. Heavily depends on #58.

[coveralls]

Coverage decreased (-0.19%) to 96.92% when pulling 2d4759c on zzk:oauth2 into 595f15d on visoft:master.

Any update on that ?

[visoft]

This was released as v0.2.0.beta. There are some bugs still in it. I'm hoping to have time to work on this in the near future. If you have time and are willing to add a PR, that would be awesome!

It doesn't seems to work with https://msdn.microsoft.com/en-us/library/mt593051.aspx for some reason it can't parse it Nokogiri::XML::XPath::SyntaxError: Undefined namespace prefix: edmx:Edmx/edmx:DataServices/* so I guess I won't be using it.

[visoft]

It looks like that's OData version 4. Currently ruby_odata doesn't support 4.0, but I'd love to change that.

After a lot of trouble I got access to Dynamics 365 on Azure Active Directory through the Web API and oauth2 authentication...

https://github.com/AzureAD/azure-activedirectory-library-for-ruby

With the secret sauce...

username      = 'admin@tenant.onmicrosoft.com'
password      = 'xxxxxxxxxxxx'
client_id     = 'xxxxx-xxxx-xxx-xxxxxx-xxxxxxx'
client_secret = 'xxxXXXxxXXXxxxXXXxxXXXXXXXXxxxxxx='
tenant        = 'tenant.onmicrosoft.com'
user_cred     = ADAL::UserCredential.new(username, password)
client_cred   = ADAL::ClientCredential.new(client_id, client_secret)
context       = ADAL::AuthenticationContext.new(ADAL::Authority::WORLD_WIDE_AUTHORITY, tenant)
resource      = "https://domain.crm6.dynamics.com"
tokens        = context.acquire_token_for_user(resource, client_cred, user_cred)

# add the access token to the request header
callback = Proc.new { |r| r.headers["Authorization"] = "Bearer #{tokens.access_token}" }

and

def request(uri, access_token)
  auth = "Bearer #{access_token}"
  Net::HTTP::Get.new(uri, 'Content-Type' => 'application/json; charset=utf-8',
    'Authorization' => auth,
    'OData-MaxVersion' => '4.0',
    'OData-Version' => '4.0',
    'Accept' => 'application/json',
    'Prefer' => 'odata.include-annotations="*"')
end

Microsoft has some ODATA v4 suppport implemented here:

Not sure if I will use this for Dynamics 365 though... but at least I got past the oauth 2.0 hurdles.

For the SOAP API (instead of Web API) on Dynamics you can use this library too: https://github.com/TinderBox/dynamics_crm

@wtfiwtz It should be the parent repository https://github.com/TinderBox/dynamics_crm the one you've linked is mine with a custom change.

Thanks @exadeci... I meant to link the parent but did that one accidentally!
