go-restful extract URL pattern path from request - rest

I am using a the emicklei/go-restful framework to deal with rest API.
I wish to access the route path from the request. Meaning that when I configure a dummy route like this:
ws := new(restful.WebService)
ws.Path("/resources/names")
ws.Route(ws.GET("/{name}").To(getName))
restful.DefaultContainer.Add(ws)
I wish to access the information that the route was "/resources/names/{name}"
I can access the actual URL which is call by calling:
req.Request.URL.Path
But this will return the specific URL, not the generic one.
Any suggestion?

After more research I finally found that the method req.SelectedRoutePath() will return expected value.

Invalid_request_parameter (create and sending envelopes)

I'm trying to use a service of DocuSign API in an abap project. I want to send a document to a specific email so it can be signed. But im getting the following error:
"errorCode": "INVALID_REQUEST_PARAMETER",## "message": "The request contained at least one invalid parameter. Query parameter 'from_date' must be set to a valid DateTime, or 'envelope_ids' or 'transaction_ids' must be specified.
I tried the following:
CALL METHOD cl_http_client=>create_by_url
EXPORTING
url = l_url (https://demo.docusign.net/restapi/v2/accounts/XXXXXX')
proxy_host = co_proxy_host
proxy_service = co_proxy_service
IMPORTING
client = lo_http_client
lo_http_client->request->set_method( method = 'POST').
CALL METHOD lo_http_client->request->set_header_field
EXPORTING
name = 'Accept'
value = 'application/json'.
CALL METHOD lo_http_client->request->set_header_field
EXPORTING
name = 'X-DocuSign-Authentication'
value = get_auth_header( ). (json auth header)
CALL METHOD lo_http_client->request->set_cdata
EXPORTING
data = create_body( ).
This is my body:
CONCATENATE
`{`
`"emailSubject": "DocuSign REST API Quickstart Sample",`
`"emailBlurb": "Shows how to create and send an envelope from a document.",`
`"recipients": {`
`"signers": [{`
`"email": "test#email",`
`"name": "test",`
`"recipientId": "1",`
`"routingOrder": "1"`
`}]`
`},`
`"documents": [{`
`"documentId": "1",`
`"name": "test.pdf",`
`"documentBase64":` `"` l_encoded_doc `"`
`}],`
`"status": "sent"`
`}` INTO re_data.
The api request to get the Baseurl is working fine. (I know the error is quite specific what the problem is, but i cant find any sources on the docusign api documentation that one of the mentioned parameters should be added to the request)
Thank you in regards
The error message seems to indicate that you're Posting to an endpoint that requires certain query string parameters -- but you're not specifying them as expected in the query string. I'd suggest you check the DocuSign API documentation for the operation you are using, to determine what query string parameters it requires, and then ensure that you're including those parameters in your request URL.
If you can't figure this out using the documentation, then I'd suggest that you update your post to clarify exactly what URL (endpoint) you are using for the request, including any querystring parameters you're specifying in the URL. You can put fake values for things like Account ID, of course -- we just need to see the endpoint you are calling, and what qs params you're sending.
To create an envelope, use
https://demo.docusign.net/restapi/v2/accounts/XXXXXX/envelopes
instead of
https://demo.docusign.net/restapi/v2/accounts/XXXXXX
Thank you for all the answers, i found the mistake. Creating the request wasn´t the problem. I was using the wrong "sending"-method -_-.
now its working :)
lo_rest_client->post( EXPORTING io_entity = lo_request_entity ).

How do I add a query parameter to a Play redirect?

If I construct a Play redirect like Redirect(routes.RegistrationController.register()), how can I add a query parameter to the URL I'm redirecting to?
For example, I'd like a URL like this: /register?token=1234.
You can just do Redirect(routes.RegistrationController.register().url + "?token=1234").
Or, supposing your route declares token as an optional parameter with the route declaration GET /register #controllers.RegistrationController(token: Option[Int]), then you could do Redirect(routes.RegistrationController.register(Some(1234))).
There are various variations to how you could set this up. You may want to see the Play router documentation.

Linkedin API oAuth 2.0 REST Query parameters

I'm running into a problem with adding a query to the callback URL. I'm getting an invalid URI scheme error attempting to authorize the following string:
https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=75df1ocpxohk88&scope=rw_groups%20w_messages%20r_basicprofile%20r_contactinfo%20r_network&state=7a6c697d357e4921aeb1ba3793d7af5a&redirect_uri=http://marktest.clubexpress.com/basic_modules/club_admin/website/auth_callback.aspx?type=linkedin
I've read some conflicting information in forum posts here. Some say that it's possible to add query strings to callbacks, and others say that it results in error.
If I remove ?type=linkedin, I can authorize just fine and receive the token. It would make my life so much easier if I could use a query string on the callback url, as I need to do some additional processing in the callback.
In short, can I append a query string to the end of the callback url?
For fun, I tried encoding the callback url in the request (obviously this is a no-no according to their documentation):
https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=75df1ocpxohk88&scope=rw_groups%20w_messages%20r_basicprofile%20r_contactinfo%20r_network&state=5cabef71d89149d48df523558bd12121&redirect_uri=http%3a%2f%2fmarktest.clubexpress.com%2fbasic_modules%2fclub_admin%2fwebsite%2fauth_callback.aspx%3ftype%3dlinkedin
This also resulted in an error but was worth a shot.
The documetation here: https://developer.linkedin.com/forum/oauth-20-redirect-url-faq-invalid-redirecturi-error indicates that you CAN use query parameters. And in the first request, it appears that I'm doing it correctly. Post #25 on this page - https://developer.linkedin.com/forum/error-while-getting-access-token indicates that you have to remove the query parameters to make it work
Anyone have experience with successfully passing additional query paramaters in the callback url for the linkedin API using oAuth2.0? If so, what am I doing wrong?
I couldn't wait around for the Linkedin rep's to respond. After much experimentation, I can only surmise that the use of additional query parameters in the callback is not allowed (thanks for making my application more complicated). As it's been suggested in post #25 from the question, I've tucked away the things I need in the "state=" parameter of the request so that it's returned to my callback.
In my situation, I'm processing multiple API's from my callback and requests from multiple users, so I need to know the type and user number. As a solution, I'm attaching a random string to a prefix, so that I can extract the query parameter in my callback and process it. Each state= will therefore be unique as well as giving me a unique key to cache/get object from cache..
so state="Linkedin-5hnx5322d3-543"
so, on my callback page (for you c# folks)
_stateString=Request["state"];
_receivedUserId = _stateString.Split('-')[2];
_receivedCacheKeyPrefix = _stateString.Split('-')[0];
if(_receivedCacheKeyPrefix == "Linkedin") {
getUserDomain(_receivedUserId);
oLinkedIn.AccessTOkenGet(Request["code"],_userDomain);
if (oLinkedin.Token.Length > 0) {
_linkedinToken = oLinkedin.Token;
//now cache token using the entire _statestring and user id (removed for brevity)
}
You not allowed to do that.
Refer to the doc: https://developer.linkedin.com/docs/oauth2
Please note that:
We strongly recommend using HTTPS whenever possible
URLs must be absolute (e.g. "https://example.com/auth/callback", not "/auth/callback")
URL arguments are ignored (i.e. https://example.com/?id=1 is the same as https://example.com/)
URLs cannot include #'s (i.e. "https://example.com/auth/callback#linkedin" is invalid)

Zend framework routing params

I have several routes defined in my application.
When route A is matched and I assemble an URL using route B without resetting, it does not include the current request parameters.
Is there an easy way to include all the request parameters when assembling an URL via a different route than the current route?
I did have a look at Zend_Controller_Router_Rewrite->useRequestParametersAsGlobal, but this will (obviously) also include the request parameters when reset = true
You could try the following.
$oldParams = $this->_getAllParamas();
unset($oldParams['module']);
unset($oldParams['controller']);
unset($oldParams['action']);
Pass
array_merge(array('new'=>'param'),$oldParams)
to your URL view helper.

http delete with REST

I am currently using Jersey Framework (JAX-RS implementation) for building RESTful Web Services. The Resource classes in the project have implemented the standard HTTP operations - GET,POST & DELETE. I am trying to figure out how to send request parameters from client to these methods.
For GET it would be in the query string(extract using #QueryParam) and POST would be name/value pair list (extract using #FormParam) sent in with the request body. I tested them using HTTPClient and worked fine. For DELETE operation, I am not finding any conclusive answers on the parameter type/format. Does DELETE operation receive parameters in the query string(extract using #QueryParam) or in the body(extract using #FormParam)?
In most DELETE examples on the web, I observe the use of #PathParam annotation for parameter extraction(this would be from the query string again).
Is this the correct way of passing parameters to the DELETE method? I just want to be careful here so that I am not violating any REST principles.
Yes, its up to you, but as I get REST ideology, DELETE URL should delete something that is returned by a GET URL request. For example, if
GET http://server/app/item/45678
returns item with id 45678,
DELETE http://server/app/item/45678
should delete it.
Thus, I think it is better to use PathParam than QueryParam, when QueryParam can be used to control some aspects of work.
DELETE http://server/app/item/45678?wipeData=true
The DELETE method should use the URL to identify the resource to delete. This means you can use either path parameters or query parameters.
Beyond that, there is no right and wrong way to construct an URL as far as REST is concerned.
You can use like this
URL is http://yourapp/person/personid
#DELETE
#Path("/person/{id}")
#Produces(MediaType.APPLICATION_JSON)
public Response deletePerson(#PathParam("id") String id){
Result result = new Result();
try{
persenService.deletePerson(id);
result.setResponce("success");
}
catch (Exception e){
result.setResponce("fail");
e.printStackTrace();
}
return Response.status(200).entity(result).build();
}
#QueryParam would be the correct way. #PathParam is only for things before any url parameters (stuff after the '?'). And #FormParam is only for submitted web forms that have the form content type.
