# Access Middleware
|
||||
|
||||
Access middleware prevents access to a route or specific route path.
|
||||
|
||||
Example of access middleware
|
||||
|
||||
```yaml
|
||||
# The server will return 403
|
||||
- name: api-forbidden-paths
|
||||
type: access
|
||||
## prevents access paths
|
||||
paths:
|
||||
- /swagger-ui/*
|
||||
- /v2/swagger-ui/*
|
||||
- /api-docs/*
|
||||
- /internal/*
|
||||
- /actuator/*
|
||||
```
|
||||
### Apply access middleware on the route
|
||||
|
||||
```yaml
|
||||
routes:
|
||||
- name: Basic auth
|
||||
path: /protected
|
||||
rewrite: /
|
||||
destination: 'https://example.com'
|
||||
methods: [POST, PUT, GET]

healthCheck:
|

# Middlewares
|
||||
|
||||
Middleware is a function executed before (or after) the route callback.
|
||||
|
||||
This is a great way to add API authentication checks, or to validate that the user has permission to access the route.
|
||||
|
||||
With Goma you can create your middleware based on the type you want and apply it on your routes
|
||||
|
||||
Goma Gateway supports :
|
||||
|
||||
- Authentication middleware
|
||||
- JWT `client authorization based on the result of a request`
|
||||
- Basic-Auth
|
||||
- OAuth
|
||||
- Rate limiting middleware
|
||||
- In-Memory client IP based
|
||||
- Access middleware

### JWT middleware
|
||||
|
||||
As BasicAuth, JWT middleware grants also access to route to authorized users only.
|
||||
It implements client authorization based on the result of a request.
|
||||
|
||||
If the request returns a 200 response code, access is allowed.
|
||||
If it returns 401 or 403, the access is denied with the corresponding error code. Any other response code returned by the request is considered an error.
|
||||
|
||||
It depends on an authentication service on the backend.
|
||||
|
||||
It works as `ngx_http_auth_request_module` on Nginx
|
||||
```conf
|
||||
location /private/ {
|
||||
auth_request /auth;
|
||||
...
|
||||
}
|
||||
|
||||
location = /auth {
|
||||
proxy_pass ...
|
||||
proxy_pass_request_body off;
|
||||
proxy_set_header Content-Length "";
|
||||
proxy_set_header X-Original-URI $request_uri;
|
||||
}
|
||||
```
|
||||
|
||||
You can also get headers from the authentication request result and inject them into the next request header or params.
|
||||
|
||||
In case you want to get headers from the authentication service and inject them into the next request headers.
|
||||
|
||||
Set the request variable to the given value after the authorization request completes.
|
||||
|
||||
Key is authentication request response header Key. Value is the next Request header Key.
|
||||
|
||||
```yaml
|
||||
headers:
|
||||
## Key Authentication request header key and value is next request header key
|
||||
userId: X-Auth-UserId
|
||||
userCountryId: X-Auth-UserCountryId
|
||||
```
|
||||
The second example, is in case you want to get headers from the authentication request and inject them into the next request parameters.
|
||||
Key is authentication request response header Key. Value is the next Request parameter Key.
|
||||
|
||||
See the example below.
|
||||
|
||||
```yaml
|
||||
# Key Authentication request header key and value is next request parameter key
|
||||
params:
|
||||
userId: userId
|
||||
userCountryId: countryId
|
||||
```
|
||||
Example of JWT middleware
|
||||
```yaml
|
||||
middlewares:
|
||||
#Enables JWT authorization based on the result of a request and continues the request.
|
||||
- name: google-auth
|
||||
# jwt authorization based on the result of backend's response and continue the request when the client is authorized
|
||||
type: jwt
|
||||
# Paths to protect
|
||||
paths:
|
||||
- /protected-access
|
||||
- /example-of-jwt
|
||||
#- /* or wildcard path
|
||||
rule:
|
||||
# This is an example URL
|
||||
url: https://www.example.com/auth/access
|
||||
# Required headers, if not present in the request, the proxy will return 403
|
||||
requiredHeaders:
|
||||
- Authorization
|
||||
#Set the request variable to the given value after the authorization request completes.
|
||||
#
|
||||
# Add header to the next request from AuthRequest header, depending on your requirements
|
||||
# Key is AuthRequest's response header Key, and value is Request's header Key
|
||||
# In case you want to get headers from the authentication service and inject them into the next request header or parameters,
|
||||
#Set the request variable to the given value after completing the authorization request.
|
||||
#
|
||||
# Add header to the next request from AuthRequest header, depending on your requirements
|
||||
# Key is AuthRequest's response header Key, and value is next request header Key
|
||||
# In case you want to get headers from the authentication service and inject them into the next request headers.
|
||||
headers:
|
||||
userId: X-Auth-UserId
|
||||
userCountryId: X-Auth-UserCountryId
|
||||
# In case you want to get headers from the Authentication service and inject them to the next request params.
|
||||
params:
|
||||
userCountryId: countryId
|
||||
```

### OAuth middleware
|
||||
|
||||
Example of Google provider
|
||||
|
||||
```yaml
|
||||
- name: google-oauth
|
||||
type: oauth
|
||||
paths:
|
||||
- /*
|
||||
rule:
|
||||
clientId: xxx
|
||||
clientSecret: xxxx
|
||||
# oauth provider google, gitlab, github, amazon, facebook, custom
|
||||
provider: google # facebook, gitlab, github, amazon
|
||||
redirectUrl: https://example.com/callback/protected
|
||||
#RedirectPath is the PATH to redirect users after authentication, e.g: /my-protected-path/dashboard
|
||||
redirectPath: /dashboard
|
||||
scopes:
|
||||
- https://www.googleapis.com/auth/userinfo.email
|
||||
- https://www.googleapis.com/auth/userinfo.profile
|
||||
state: randomStateString
|
||||
jwtSecret: your-strong-jwt-secret | It's optional
|
||||
|
||||
```
|
||||
|
||||
Example of Authentik provider
|
||||
|
||||
```yaml
|
||||
- name: oauth-authentik
|
||||
type: oauth
|
||||
paths:
|
||||
- /protected
|
||||
- /example-of-oauth
|
||||
rule:
|
||||
clientId: xxx
|
||||
clientSecret: xxx
|
||||
# oauth provider google, gitlab, github, amazon, facebook, custom
|
||||
provider: custom
|
||||
endpoint:
|
||||
authUrl: https://authentik.example.com/application/o/authorize/
|
||||
tokenUrl: https://authentik.example.com/application/o/token/
|
||||
userInfoUrl: https://authentik.example.com/application/o/userinfo/
|
||||
redirectUrl: https://example.com/callback
|
||||
#RedirectPath is the PATH to redirect users after authentication, e.g: /my-protected-path/dashboard
|
||||
redirectPath: ''
|
||||
#CookiePath e.g.: /my-protected-path or / || by default is applied on a route path
|
||||
cookiePath: "/"
|
||||
scopes:
|
||||
- email
|
||||
- openid
|
||||
state: randomStateString
|
||||
jwtSecret: your-strong-jwt-secret | It's optional
|
||||
|
||||
```
|
||||
### Access middleware
|
||||
|
||||
Access middleware prevents access to a route or specific route path.
|
||||
|
||||
Example of access middleware
|
||||
```yaml
|
||||
# The server will return 403
|
||||
- name: api-forbidden-paths
|
||||
type: access
|
||||
## prevents access paths
|
||||
paths:
|
||||
- /swagger-ui/*
|
||||
- /v2/swagger-ui/*
|
||||
- /api-docs/*
|
||||
- /internal/*
|
||||
- /actuator/*
|
||||
```
|
||||
### RateLimit middleware
|
||||
|
||||
The RateLimit middleware ensures that services will receive a fair amount of requests, and allows one to define what fair is.
|
||||
|
||||
Example of rateLimit middleware
|
||||
```yaml
|
||||
|
||||
```
|
||||
|
||||
### Apply middleware on the route
|
||||
|
||||
```yaml
|
||||
##### Define routes
|
||||
routes:
|
||||
- name: Basic auth
|
||||
path: /protected
|
||||
rewrite: /
|
||||
destination: 'https://example.com'
|
||||
methods: [POST, PUT, GET]
|
||||
healthCheck:
|
||||
cors: {}
|
||||
middlewares:
|
||||
- oauth-authentik
