Zuul Block Headers - netflix-zuul

I'm trying to recibe an Autorization Header from a Response but Zuul Block it.
I try:
zuul:
routes:
users:
sensitiveHeaders: Autorization
but it doesn't work :S

It works with this configuration in:
aplication.yml
zuul:
# exclude Authorization from sensitive headers
sensitiveHeaders: Cookie,Set-Cookie

How to add Accept, Authorization or Content-Type in OpenAPI 3.0?

My spec is as below.
/path:
/user:
get:
parameters:
- name: Authorization
in: header
required: true
schema:
type: string
Problem is that it is giving me the below warning. I get the same warning if I add Content-Type or Accept header.
Header parameters named Authorization are ignored. Use securitySchemes and security to define the Authorization
I tried the below but I don't see Authorization header added in the request. I am using https://editor.swagger.io to create the spec.
/path:
/user:
get:
parameters:
- name: Authorization
in: header
required: true
schema:
type: string
security:
- my_auth: []
components:
securitySchemes:
my_auth:
type: http
scheme: bearer
bearerFormat: JWT
Any help is appreciated. Thanks !!
In the request parameters, there are operation's specific parameters.
The general purpose HTTP headers aren't defined here because:
Content-Type is defined by the request body content. If there are multiple content types, the consumer has to choose and set Content-Type accordingly.
Accept is similar; it only relates to the response message.
For security, we do not describe the Authorization header but instead define the security scheme (see docs for more).
You may use the description property to explain how to use these headers with your API. However, if your API follows standards, it should not be necessary.
Once you have added the security schema to your API definition, you can use the Authorization function of Swagger Editor. So, you will add your token and trigger "Try it out." Swagger will populate the Authorization header; see the attached screenshot.

Is it possible to set the Micronaut OAuth2 callback-uri as an absolute URL?

I have a Micronaut web-app that uses OpenId / OAuth2 / JWT. In some environments, everything works really well with this set up, however, in other environments, auth fails during the step where the configured callback-uri is called. For some reason, in these environments, the URL generated is "http" instead of "https". This causes the call to fail since my application is only accessible over https.
I have no clue why it is trying to use http in the first place, however, if I was able to specify the callback-uri as an absolute / full URL, then I could probably work around this anomaly in these environments.
An example yml config that I use:
application:
name: xxxxx
security:
authentication: idtoken
oauth2:
enabled: true
clients:
azure:
client-id: ${OAUTH_CLIENT_ID}
client-secret: ${OAUTH_CLIENT_SECRET}
openid:
issuer: https://login.microsoftonline.com/xxx
callback-uri: ${OAUTH_CALLBACK_URI}
redirect:
login-success: ${LOGIN_SUCCESS_URL}
logout: '/logout-handler/logout-success'
endpoints:
logout:
get-allowed: true
token:
jwt:
cookie:
cookie-same-site: none
cookie-secure: true
In this config if I set the callback-uri environment variable (OAUTH_CALLBACK_URI) to /oauth/callback/azure, for example, then the full URL that seems to be used is http://xxxxx/oauth/callback/azure. However, if I use a full URL for the environment variable, e.g. https://xxxxx/oauth/callback/azure then the full URL it uses still appends that as opposed to using it as an absolute URL, i.e. http://xxxxx/https://xxxxx/oauth/callback/azure.
Is it possible to specify this uri as an absolute one and not have it append it like the above effectively duplicating it?
Good news. This was fixed in micronaut-security 2.3.4

Multiple ORIGINS for CORS not working in case of custom authorizer error

I have CORS enabled in the application and have multiple origins, Its working fine with normal requests and error responses. But when I am getting some error in custom authorizer or deny the authorization. The CORS is not working for any status code(4XX or 5XX). I don't want to use * and have to handle multiple origins. I am using serverless
Here is the snippet from serverless.yml
resources:
Description: My backend
Resources:
GatewayResponseDefault4XX:
Type: 'AWS::ApiGateway::GatewayResponse'
Properties:
ResponseParameters:
gatewayresponse.header.Access-Control-Allow-Origin: "'qwe.xyz.com,abc.xxxx.com,xyz.xxxx.xom'"
gatewayresponse.header.Access-Control-Allow-Headers: "'qwe.xyz.com,abc.xxxx.com,xyz.xxxx.xom'"
ResponseType: DEFAULT_4XX
RestApiId:

gatewayresponse.header.Access-Control-Allow-Headers: "'qwe.xyz.com,abc.xxxx.com,xyz.xxxx.xom'"
ResponseType: DEFAULT_5XX

Could you please help me to find a solution if I have multiple origins. How to handle multiple origins if default gateway responses for error codes

Zuul prefix when more than a single /path

I have a service with this path http://myhost.com/v2/1234/brand/order/issues/123 that needs to send the actual call to http://anotherhost.com/issues/123.
If I want to avoid the solution to write a ZuulFilter
Is there a way, with the configuration to say: the prefix is /v2/*/*/order/issues and just use 123?
zuul:
routes:
test2:
path: /v2/*/*/orders/issues/**
url: http://anotherhost.com/issues/
stripPrefix: true
No, there's no way to configure such behaviour. You need to create custom ZuulFilter
By default Zuul will only strip prefixes that do not contain special characters. e.g.
zuul:
routes:
test1:
path: /orders/** <--- '/orders' is stripped
url: http://anotherhost.com/issues/
test2:
path: /*/orders/** <--- nothing is stripped
url: http://anotherhost.com/issues/

Swagger-ui only sending OPTIONS not POST http method despite working API

I am using Swagger-UI to browse my own API, built with grape and automatically documented with grape-swagger.
I've googled and tried every suggestion I can find, but I cannot get POST to work. Here's my headers:
header "Access-Control-Allow-Origin", "*"
header "Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, PATCH, DELETE"
header "Access-Control-Request-Method", "*"
header "Access-Control-Max-Age", "1728000"
header "Access-Control-Allow-Headers", "api_key, Content-Type"
I just threw in everything suggested. I've enabled all the HTTP methods in supportedSubmitMethods and I have tested the API using the POSTMAN Chrome extension and it works perfectly. Creates a user properly and returns the correct data.
However all I get with swagger post is the server reporting:
Started OPTIONS "/v1/users.json" for 127.0.0.1 at 2012-12-21 04:07:13 -0800
and swagger response looking like this:
Request URL
http://api.lvh.me:3000/v1/users.json
Response Body
Response Code
0
Response Headers
I have also tested the OPTIONS response with POSTMAN and it is below:
Allow →OPTIONS, GET, POST
Cache-Control →no-cache
Date →Fri, 21 Dec 2012 12:14:27 GMT
Server →Apache-Coyote/1.1
X-Request-Id →9215cba8da86824b97c6900fb6d97aec
X-Runtime →0.170000
X-UA-Compatible →IE=Edge
I had the same problem and just solved it, hope this helps somebody.
Swagger-UI accepts multiple parameters through POST only through a 'form' paramType, not 'body' paramType, referenced in this issue https://github.com/wordnik/swagger-ui/issues/72.
I used the branch :git => 'git://github.com/Digication/grape-swagger.git' changing 'post' request paramType to 'form'. Generated xml output for swagger_doc (probably at path/swagger_doc/api or similar) should look something like this:
<api>
<path>/api/v2/...</path>
<operations type="array">
...
<httpMethod>POST</httpMethod>
<parameters type="array">
<parameter>
<paramType>form</paramType>
...More
Not
<paramType>body</paramType>
...More
I used the grape-swagger-rails gem to automatically install swagger-ui on localhost (files can also be downloaded from the swagger-ui site), and everything works!!
Had the same problem. Fixed by adding CORS
add into Gemfile:
gem 'rack-cors', :require => 'rack/cors'
add into application.rb
config.middleware.use Rack::Cors do
allow do
origins '*'
# location of your API
resource '/*', :headers => :any, :methods => [:get, :post, :options, :put]
end
end
be sure that you've changed location of your API here.
Nice to hear you are using grape-swagger: I think it is awesome :)
I am not entirely sure you are having the same problem, but when testing locally from the browser it will try to check if the origin is the same as requested, so to make sure I do not get that error, I created a small middleware that will tell the browser we allow all origin.
I am using a rails process (created with the awesome rails-api gem), so I create a new file in lib/middleware/access_control_allow_all_origin.rb with the following content:
module Middleware
class AccessControlAllowAllOrigin
def initialize(app)
#app = app
end
def call(env)
status, headers, body = #app.call(env)
allow_all_origin!(headers)
[status, headers, body]
end
private
def allow_all_origin!(headers)
headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Request-Method'] = '*'
end
end
end
and at the bottom of my application.rb I just add the middleware as follows:
require 'middleware/access_control_allow_all_origin'
config.middleware.insert_after Rack::ETag, Middleware::AccessControlAllowAllOrigin
Hope this helps.
I do not know about the solution for ruby-on-rails as I am using Swagger with play framework 2.0.2.
I provided a domain name to it and changed the basePath to domain name in application.conf file as swagger.api.basepath="domain-name" and it worked.
You can change the basePath in api-docs to domain-name. I read about the api-docs on
api-docs.
And does your web server hijack headers? If you are using NGinx for example, your "OPTIONS" request might not send the appropriate values as a response, in some cases.
What is your OPTIONS request response? Can you dump it out here? I'll tell you if it can be that.
