I'm trying to connect to a web server (http/port:80) via a secure gateway (DataPower) from my Bluemix account. I have set everything up and I can see the destination etc. is enabled in my dashboard. I am using Java to connect to the secure gateway but I must be missing something since I keep getting a 403 returned from the gateway client.
I have added:
connection.setRequestProperty("Authorization", "Bearer " + token);
But it still fails with a 403. I'm assuming that I also need to supply the Gateway Id... but cannot find any docs or Java examples...

I am using angular-oauth2-oidc to connect to Keycloak server which is behind nginx.
I am using code flow for retrieving the token.
Even when using HTTP also, I see a GET request being sent for /protocol/openid-connect/certs
which is failing since the frontend APIs are having the correct hostname, but the backend APIs (jwks_uri) is having localhost.
Also, I am unable to set the KC_HOSTNAME_STRICT_BACKCHANNEL=true since the backend microservices will not be able to connect to Keycloak.
Is there a workaround for this.
I just created an REST API in API Connect and the endpoint works when I test it in the APIC assemble tab. It requires a client id and client secret. When I send a request through Postman, I currently get a “Could not get any response” message from when I try to add them as header values or OAuth authorization. I’m using the request endpoint that’s displayed when I hit the debug button from the successful response on the Assemble tab. Is this the correct endpoint to use? How do I properly include the client id and client secret in a Postman request?
If you get a "Could not get any response in Postman", that means that Postman can't reach the destination of the request.
There are several reasons for that:
Is it an intranet or internet endpoint?
Are you using a proxy? (check proxy config)
Is the hostname resolvable? (try ip)
If it is an https
endpoint, with a self signed certificate, check if you have SSL
Certificate verification enabled (Settings-> general)
On the other hand, to send the client-id and client-secret headers, just click on Headers tab and add both (see the following picture)
Please check the below things to get access to API Connect published services.
Service needs to be allowed to invoke from postman(System from which you are invoking.)
Please check the web-api MPGW service titled in DataPower default domain created when you configure your API connect with DataPower have you created an access control list in the front-side-handler.
Please disable the SSL configuration in the postman, sometime this may create a problem(since the service exposed from API Connect will be with SSL)
From the error you are getting, I suspect there is no connection or only one-way traffic is enabled which means you are blocking response. If there is an issue with the request parameters you are sending, an error will be different saying, wrong client id or client secret.
Testing API which is on-boarded from API Connect will be straightforward or same we invoke other rest services.
Thx Srikanth
I needed to include the client id and client secret in the headers using the correct name for them, which is specified when creating/editing the api under the 'Security Definitions' category as 'Parameter Name'.
I was also hitting the wrong endpoint. To find the correct endpoint click the hamburger icon in the upper left of api connect website, select dashboard, click on the environment you want such as sandbox or dev, click settings, click gateway, then you'll see the endpoint.
I'm trying to setup AWS Api Gateway as a reverse proxy for my actual deployed API.
My understanding is that I do this by creating a "Proxy" Resource and then specifying my http endpoint URL - as described here
Create and Test an API with HTTP Proxy Integration through a Proxy Resource
This works fine when I try to use the API through the "Test" function within the Resource Editor. I can make calls to any exposed resources using GET methods and see the successful responses.
However, when I deploy the API Gateway API I can no longer access anything using the "Invoke URL" it gives me - I simply get:
{
"Message": "No HTTP resource was found that matches the request URI 'http://<myuniqueid>.execute-api.eu-west-1.amazonaws.com/api/Sector/100'.",
"MessageDetail": "No type was found that matches the controller named 'Sector'."
}
If I remove the "Use HTTP Proxy integration" checkbox from the "Integration Request" I can get it working, but why doesn't it work as a proxy?
I suspect that this is caused by a known issue with the HTTP proxy integration. When you use an HTTP proxy integration, API Gateway passes all headers through to the integration endpoint, including the HOST header. Many existing http endpoint require the use of a HOST header which matches their DNS name and in such cases, passing through the HOST header of the API Gateway can confuse the endpoint.
UPDATE: We identified a work-around for this issue.
In your integration request, explicitly add a header named "Host" and give it the value of the integration endpoint DNS name. This will replace the Host header forwarded from the incoming client request with the Host header you specify. This should allow your backend endpoint to function correctly.
I have a web .NET service. I can connect this web service from web browsers.
If I write service address first web browser ask username and password than service is connected.
If I connect this web service with delphi. There is error message:
Error message is "401 Unauthorized"
I am using:
RESTResponse1
RESTRequest1
RESTClient1 and HTTPBasicAuthenticator 1.
HTTPBasicAuthenticator1 has username and password and RestClient add Authenticator.
But I can not connect web service
How can I connect it?
To find out the reason for the missing (or wrong) authentication you can use the developer / debug mode in most web browsers. You could also use Wireshark or a HTTP proxy.
Check the response headers of the server. They include information about all supported authentication modes (see RFC 2616)
I have created an API via basic secure connector (SOAP). The API works but I am wondering why I can't retrieve the endpoint URL from VCAP_SERVICES. Anything I miss here?
Are you using the secure connector portion of the Cloud Integration service in Bluemix? You might want to try the Secure Gateway service, which is newer and is basically just the secure connector as a standalone service without the rest of Cloud Integration.
"Reaching enterprise backend with Bluemix Secure Gateway via console" explains how to set up a Secure Gateway instance. When you create a destination, that creates an integration.ibmcloud.com URL that your app can then use to connect to your destination via the gateway. The gateway is a proxy, preserving the interface, so the cloud host URL has the same API as the destination host.
