HTTP newbie here.
trying to call an action via. Postman.
Action looks like this:
<Action Name="SampleAction" IsBound="true">
<Parameter Name="bindingParameter" Type="NAV.DvTableDvProfile"/>
</Action>
My presumption was that something like this would work:
http://xxxx/DvTableDvProfile/SampleAction
I have tried different combinations of parameters etcetera.
The error I get:
: "The request URI is not valid. Since the segment 'DvTableDvProfile'
refers to a collection, this must be the last segment in the request
URI or it must be followed by an function or action that can be bound
to it otherwise all intermediate segments must refer to a single
resource."
Not sure where to go from here. Help is appreciated.

Can't find how to send edm.time as a parameter in get request in an url.
Tried many variations but with no luck.
I think it has to do maybe with character escaping but it didn't work for me either, I'm probably missing out something.
For example, I tried:
http::<some_url>/some_func?time=time120000
EDIT 1:
I tried the example from the other thread posted here and it also doesn't work: /func(time=‘PT11H00M00S’). this raises an error.
EDIT 2:
I'm trying to pass this edm.time to a function import.
dataserviceversion version is 2.0.
<FunctionImport Name ="<some_func>" m:HttpMethod="GET" ReturnType="<string>">
<Parameter Name="timeIN" Type="Edm.Time" Precision="0" Mode="In" />
</FunctionImport>
Answer is:
func_imp_ex?timeIN=time'PT18H31M41S'
Needed to prefix the string with the word key 'time'
[HttpPatch]
public HttpResponseMessage UpdateDividendInformation([FromBody]BEDividendInformationRequest bedividendInformationRequest, Delta<BEAccountDividendSetup> beAccountDividendSetup)
When I am calling from fiddler using http patch its showing:
"Can't bind multiple parameters error" .
Please anyone help in this. I am using Delta class for tracking changed entities. So how to send values through fiddler.
Basically, There is at most 1 parameter allowed from body because the request content maybe read only once.
In your action, you mark the first parameter [FromBody], meantime, Delta<T> is decorated with [NonValidatingParameterBinding] attribute in OData Web API, That's a parameter from body. So, you have two parameters which will bind from body. Therefore, it's obvious that you got the such error message.
However, the error message should contain the parameter names. Do you omit it?
I did create a simple testcase in JMeter.
Open a form and all it's content (css, images etc) :
GET /
GET /css/site.css
GET /favicon.ico
GET /fonts/specific-fonts.woff
GET /images/banner.png
Wait a little...
Post the values
POST /
Receive the "Thank You" page.
- GET /thanks
In the response on the first GET is a hidden input field which contains a token. This token needs to be included in the POST as well.
Now I use the "Regular Expression Extractor" of JMeter to get the token from the response. So far, so good.
Then, after retreiving all the other contents I create the POST message, using the variable name in the RegExp-Extractor in the value field of the token parameter.
But... when executing the testcase it fills in the default value given and not the actual value of the token.
So... first step in debugging this issue was to add a dummy-HTTP-GET request directly after I get the token. In this GET request I also add the token parameter with the token variable as value, but now I can easily check the parameter by looking at the access-log on my webserver.
In this case... the URL looks promising. It contains the actual token value in the GET, but it still uses the default value in the POST.
Second step in debugging was to use the "Debug Sampler" and the "View Results Tree".
By moving the Debug Sampler between the different steps I found out the value of the token-variable is back to the default value after I receive the CSS.
So... now the big question is...
How can I make JMeter to remember my variable value until the end of my test-script ?
JMeter doesn't "forget" variables. However variables scope is limited to the current Thread Group. You can convert JMeter variable to JMeter Property which have "global" scope by i.e. using Beanshell Post Processor with the following code:
props.put("myVar", vars.get("myVar"));
Or by using __setProperty() function. See How to Use Variables in Different Thread Groups guide for details.
As you found it your problem comes from a misunderstanding of scoping rules in jmeter.
https://jmeter.apache.org/usermanual/test_plan.html#scoping_rules
In your case, just put the post processor of the request that will give you the response containing the child node.
Also I think you don't need to share this token with other threads so don't use properties as proposed in the alternate answer.
Let's say you want to get list of users by calling GET to api/users, but currently the table was truncated so there are no users. What is the proper response for this scenario: 404 or 204?
I'd say, neither.
Why not 404 (Not Found) ?
The 404 status code should be reserved for situations, in which a resource is not found. In this case, your resource is a collection of users. This collection exists but it's currently empty. Personally, I'd be very confused as an author of a client for your application if I got a 200 one day and a 404 the next day just because someone happened to remove a couple of users. What am I supposed to do? Is my URL wrong? Did someone change the API and neglect to leave a redirection.
Why not 204 (No Content) ?
Here's an excerpt from the description of the 204 status code by w3c
The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation.
While this may seem reasonable in this case, I think it would also confuse clients. A 204 is supposed to indicate that some operation was executed successfully and no data needs to be returned. This is perfect as a response to a DELETE request or perhaps firing some script that does not need to return data. In case of api/users, you usually expect to receive a representation of your collection of users. Sending a response body one time and not sending it the other time is inconsistent and potentially misleading.
Why I'd use a 200 (OK)
For reasons mentioned above (consistency), I would return a representation of an empty collection. Let's assume you're using XML. A normal response body for a non-empty collection of users could look like this:
<users>
<user>
<id>1</id>
<name>Tom</name>
</user>
<user>
<id>2</id>
<name>IMB</name>
</user>
</users>
and if the list is empty, you could just respond with something like this (while still using a 200):
<users/>
Either way, a client receives a response body that follows a certain, well-known format. There's no unnecessary confusion and status code checking. Also, no status code definition is violated. Everybody's happy.
You can do the same with JSON or HTML or whatever format you're using.
I'd answer one of two codes depending on runtime situation:
404 (Not Found)
This answer is pretty correct if you have no table. Not just empty table but NO USER TABLE. It confirms exact idea - no resource. Further options are to provide more details WHY your table is absent, there is couple of more detailed codes but 404 is pretty good to refer to situation where you really have no table.
200 (OK)
All cases where you have table but it is empty or your request processor filtered out all results. This means 'your request is correct, everything is OK but you do not match any data just because either we have no data or we have no data which matches your request. This should be different from security denial answer. I also vote to return 200 in situation where you have some data and in general you are allowed to access table but have no access to all data which match your request (data was filtered out because of object level security but in general you are allowed to request).
If you are expecting list of user object, the best solution is returning an empty list ([]) with 200 OK than using a 404 or a 204 response.
definitely returns 200.
404 means resource not found. But the resource exists. And also, if the response has 404 status. How can you know users list empty or filled?
'/users' if is empty should return '200'.
'/users/1' if the id is not found. should return 404.
It must 200 OK with empty list.
Why: Empty table means the table exists but does not have any records.
404 Not Found means requested end point does not exist.
I am sending an url parameter to servlet using the following jQuery piece:
$.getJSON("http://localhost:8080/JsoupPrj/JasonGen?url=" + url, function(data) {
$("#content").html(data);
});
On the server side, the servlet gets the parameter, for that I coded as below:
String url = (String) request.getAttribute("url");
But it is not working, can you tell me where I am doing wrong? I believe I am not passing the parameter properly to the servlet. The servlet triggers each time through the JavaScript, but it is not seeing the parameters passed from the browser.
Here,
String url = (String) request.getAttribute("url");
you're trying to get a request parameter as a request attribute instead of as a request parameter. This will obviously not do what you want.
You need to get a request parameter as a request parameter, not as a request attribute.
String url = request.getParameter("url");
Unrelated to the concrete problem: you don't seem to be URL-encoding the parameter at all before sending. This will possibly cause other problems, unrelated to this one, when the url contains special characters. Look at the JS encodeURIComponent() function, or the data argument of the $.getJSON() function. See for more hints also How to use Servlets and Ajax?
