We have configured REST proxy service that accepts JSON input. If the input is not a well formed JSON OSB is throwing Translation error with HTTP 500 Staus code. Is that possible we can send Customized error message in this scenario
You need to create a global error handler for your pipeline and set the desired error message using a replace action here, followed by a "Reply" action.
Keep in mind that if you try to "read" the original request body in the global error handler, and if the original request was malformed, it will get thrown up to the system error handler and you will get the system error message again.
Here's a sample OSB 12.2.1.1 project you can use to try this: https://github.com/jvsingh/SOATestingWithCitrus/tree/develop/OSB/Samples/ServiceBusApplication1
The accompanying soapui project contains two requests. The malformed request should return this:
(I have only set the response here. You would also need to set the proper content type and decide whether you want to treat this as "success" or "failure" etc. in the reply action)

I'm requesting to https://xx.xx.x.xxx/consumers/ domain and I'm getting some response data as JSON format, and I'm passing it another endpoint direct:consumer, but in direct:consumer endpoint if print body I'm getting empty, could anyone help me how to transfer the data from one endpoint to another endpoint.
from("timer://runOnce?repeatCount=1")
.process(consumerCreate)
.to("https://xx.xx.x.xxx/consumers/").log("response data from create:: ${body}")
.to("direct:consumer");
In the below endpoint, if print the body getting an empty response, not getting JSON data
from("direct:consumer").log("the body is ${body} ");
Can anyone please help me is it expected behaviour or am I missing something?
Take a look at enabling steam caching:
https://camel.apache.org/manual/latest/stream-caching.html
Without it, the stream returned by http producer can only be read once, e.g in the first log message. Hence why nothing is printed in the second direct:consumer route when it comes to log the message body.
I have successfully created a new user in Azure AD following Create User reference.
Now I want to update that very same user following Update User reference. To keep things simple This is the JSon content I'm sending:
{
"userType": "T"
}
The documentation tells me to send a PATCH request, but I always receive an HTTP Error 400 (Bad request). If I try sending a POST request I receive an HTTP Error 405 (Method not allowed).
The destination URL is https://graph.microsoft.com/v1.0/users/user-id.
The user-id is the one returned with the user details.
What am I missing?
Update 1
Those are the permissions set to the application:
This is exactly how you update user (PATCH).
However the userType property cannot be T, from the docs you refer:
That property can only have one of the two distinct values: Member or Guest.
Of course, the user-id in path should the id property as returned by the get users operation.
I am pretty sure that if you use a normal REST client will be able to see the whole error message, which will be more meaningful.
If you still have issue - paste the exact error message.
I have written an apache 2.x module that attempts to scan request bodies, and conditionally return 403 Forbidden if certain patterns match.
My first attempt used ap_hook_handler to intercept the request, scan it and then returned DECLINED to the real handler could take over (or 403 if conditions were met).
Problem with that approach is when I read the POST body of the request (using ap_get_client_block and friends), it apparently consumed body so that if the request was subsequently handled by mod_proxy, the body was gone.
I think the right way to scan the body would be to use an input filter, except an input filter can only return APR_SUCCESS or fail. Any return codes other than APR_SUCCESS get translated into HTTP 400 Bad Request.
I think maybe I can store a flag in the request notes if the input filter wants to fail the request, but I'm not sure which later hook to get that.
turned out to be pretty easy - just drop an error bucket into the brigade:
apr_bucket_brigade *brigade = apr_brigade_create(f->r->pool, f->r->connection->bucket_alloc);
apr_bucket *bucket = ap_bucket_error_create(403, NULL, f->r->pool,
f->r->connection->bucket_alloc);
APR_BRIGADE_INSERT_TAIL(brigade, bucket);
bucket = apr_bucket_eos_create(f->r->connection->bucket_alloc);
APR_BRIGADE_INSERT_TAIL(brigade, bucket);
ap_pass_brigade(f->next, brigade);
All,
Is there a way to error out/exit execution out of a handler? For instance, if the incoming request doesn't contain the correct headers we want to send a 400 and exit/close the connection. However, whenever we use self.error(400) or self.response.set_status(400) any other code after it executes anyway So, for example:
class MyPastaHandler(webapp2.Handler):
def get():
if not self.request.headers.get('My-Custom-Header'):
self.error(400)
...
[more code]
self.response.out.write('{"success": "true"}')
When I submit a request w/o the said custom header, I get back a 400, but I also get the success json in the body of the response, which tells me that self.error(400) doesn't stop execution and neither does self.response.set_status(400).
So, the question is, is it possible to literally error out of a handler?
As it turns out, there is a simple way to exit after a 400 (or any custom error). As described by TheFluff in the AppEngine IRC channel, a simple, old-fashioned empty return after the self.error(400) will do the trick.
In webapp2 abort() is a shortcut to raise a HTTP exception: http://webapp-improved.appspot.com/guide/exceptions.html#abort
I would like to achieve the following kind of orchestration with CAMEL:
Client sends a HTTP POST request to CAMEL
CAMEL sends HTTP POST request to external endpoint (server)
External server replies with a 200 OK
CAMEL sends HTTP GET request to external endpoint (server)
External server replies
After step 5, I want to check the reply: if the reply is a 200 OK and state = INPROGRESS (this state can be retrieved from the received XML body), I want to re-transmit the HTTP GET to the external endpoint until the state is different from INPROGRESS.
I was thinking to use the retryWhile statement, but I am not sure how to build the routine within the route.
Eg, for checking whether the reply is a 200 OK and state = INPROGRESS, I can easily introduce a Predicate. So the retryWhile already becomes like:
.retryWhile(Is200OKandINPROGRESS)
but where should I place it in the route so that the HTTP GET will be re-transmitted ?
Eg: (only taking step 4 and 5 into account)
from("...")
// here format the message to be sent out
.to("external_server")
// what code should I write here ??
// something like:
// .onException(alwaysDo.class)
// .retryWhile(Is200OKandINPROGRESS)
// .delay(2000)
// .end ()
// or maybe it should not be here ??
I am also a bit confused how the "alwaysDo.class" should look like ??
Or ... should I use something completely different to solve this orchestration ?
(I just want to re-transmit as long as I get a 200 OK with INPROGRESS state ...)
Thanks in advance for your help.
On CAMEL Nabble, someone replied my question. Check out:
http://camel.465427.n5.nabble.com/Camel-Apache-can-I-use-a-retryWhile-to-re-send-a-request-td5498382.html
By using a loop statement, I could re-transmit the HTTP GET request until I received a state different from INPROGRESS. The check on the state needs to be put inside the loop statement using a choice statement. So something like:
.loop(60)
.choice()
.when(not(Is200OKandINPROGRESS)).stop() // if state is not INPROGRESS, then stop the loop
.end() // choice
.log("Received an INPROGRESS reply on QueryTransaction ... retrying in 5 seconds")
.delay(5000)
.to(httpendpoint")
.end() //loop
I never experimented what you are trying to do but it seems does not seem right.
In the code you are showing, the retry will only occur when an alwaysDo Exception is thrown.
The alwaysDo.class you are refering to should be the name of the Java Exception class you are expecting to handle. See http://camel.apache.org/exception-clause.html for more details.
The idea should be to make the call and inspect the response content then do a CBR based on the state attribute. Either call the GET again or terminate/continue the route.
You probably should write a message to the Apache Camel mailing list (or via Nabble) . Commiters are watching it and are very reactive.
