Use OAuth2 middleware to secure HTTP endpoints

The OAuth2 HTTP middleware enables the OAuth2 Authorization Code flow on a Web API without modifying the application. This design separates authentication/authorization concerns from the application, so that application operators can adopt and configure authentication/authorization providers without impacting the application code.

Component format

apiVersion: dapr.io/v1alpha1

  version: v1
  - name: clientId
    value: "<your client ID>"
  - name: clientSecret
    value: "<your client secret>"
  - name: scopes
    value: "https://www.googleapis.com/auth/userinfo.email"
  - name: authURL
    value: "https://accounts.google.com/o/oauth2/v2/auth"
  - name: tokenURL
    value: "https://accounts.google.com/o/oauth2/token"

    value: "authorization"
  - name: forceHTTPS
    value: "false" 

Spec metadata fields

Field Details Example
clientId The client ID of your application that is created as part of a credential hosted by a OAuth-enabled platform
clientSecret The client secret of your application that is created as part of a credential hosted by a OAuth-enabled platform
scopes A list of space-delimited, case-sensitive strings of scopes which are typically used for authorization in the application "https://www.googleapis.com/auth/userinfo.email"
authURL The endpoint of the OAuth2 authorization server "https://accounts.google.com/o/oauth2/v2/auth"
tokenURL The endpoint is used by the client to obtain an access token by presenting its authorization grant or refresh token "https://accounts.google.com/o/oauth2/token"
redirectURL The URL of your web application that the authorization server should redirect to once the user has authenticated "https://myapp.com"
authHeaderName The authorization header name to forward to your application "authorization"
forceHTTPS If true, enforces the use of TLS/SSL "true","false"

Dapr configuration

To be applied, the middleware must be referenced in configuration. See middleware pipelines.

apiVersion: dapr.io/v1alpha1
kind: Configuration
  name: appconfig
    - name: oauth2
      type: middleware.http.oauth2
