postman get not passing parameters in short format - http

I am trying to send a get request with postman. If I pass parameters like this
{{base_url}}/api/v1/views/PersonView?LastName=SomeLastName
It doesn't recognize them and I get the same response as for "{{base_url}}/api/v1/views/PersonView"
But if I pass parameters like this
{{base_url}}/api/v1/views/PersonView?param[0][name]=LastName&param[0][op]=eq&param[0][value]=SomeLastName
then i get the correct answer. As far as I understand, both approaches are the same, only the format is different. What could be the problem with sending parameters as shown in the first example?

API POST with authentication in R

I'm trying to make a POST action on Bitmex to buy 1 contract called XBTUSD (bitcoin/usd) at price 4009.9, with expiring time 1545674400 (UNIX timestamp, a couple hours from now) and we need to be authenticated. This looks simple.
We are using API and we are writing in R. (api-secret is fake sorry!!!)
We need to transform our request with hmac in a signature to make it a number in base 16.
We try to define our signature
signature=hmac("Kjxd5H5sPnBq6oXmnKrQAbKPIAXuKsInHRmD9CF2Dh3-4I6j", 'POST/api/v1/order1545674400{"symbol":"XBTUSD","price":4009.0,"orderQty":1}', algo = "sha256")
and then to POST
POST("https://www.bitmex.com/api/v1/order",body = 'POST/api/v1/order1545674400{"symbol":"XBTUSD","price":4009.0,"orderQty":1}',add_headers("api-key":"R1IdBlJD0-fCXypR2TTQVCF6", "api-signature":signature))
or similar stuff, and we get
403 or 401
I don't understand what's wrong. I'm able make requests which don't need authentication, but not those with it!
Thanks!
from the first glance, you seem to have forgotten 'api-expires' parameter among headers.
Method that works for me is, that body is a named list (if you are using httr package) with aditional parameter inside 'POST' function call: encode = 'json'.
If you want to see what the errors mean in more detail, do the following:
msg = POST(....)
rawToChar(msg$content)

Using a substring of a return value in a subsequent request

I'm attempting to construct a series of Paw calls using the variables feature. I have one situation I'm unable to solve.
At authentication into the server I'm using, I get a JSON response, with one value that looks like this:
endpoint = "https://sub.something.com/thingone/thingtwo.php?token=sometoken&id=blahblah"
The endpoint portion "https://sub.something.com/" is then used as the base for subsequent calls, where a call might be "GET https://sub.something.com/data?id=123".
I don't want to hardcode the endpoint in Paw, as the endpoint will vary based on factors I can't predict at my end.
Is there a way to do basic string processing like this either in Paw, or by calling out to a shell script and using the return value of said script as a Paw variable?
That's doable using that RegExp Match dynamic value extension. Click on that previous link and hit Install Extension.
Type "Regexp" in the field you expect this value to be used. Pick Regexp Match from the completion results:
Then enter a regexp that matches your need, https?://[^/]+/? should be good:
I've put your example string in the screenshot above to show that it works, but you can instead put a "pointer" (Response Dynamic Value) to the response you want:
In the choices, pick Response Parsed Body if you want to parse a JSON or XML from the reponse. If the string is simply in plain text in the response body, pick Response Raw Body.
Once these steps are completed, you've got a working "Pointer" + "Parser" to the response that extract the part of the string you need. You can do the same operation with another regex for the token…
Tip: these dynamic value tokens can be selected like text and copy/pasted (Cmd+C/Cmd+V) :-)

Paw app query request

Hi I am attempting to initiate a query to my backend on Kinvey which is backed by a MongoDB. They require passing URL parameters as such:
?query={"firstName":"James"}
I have tried every imaginable way of setting up these parameters in PAW but either get a success response with no filtering of the data or an error message of URL not supported when I try using a Raw Query String.
I have ran the query using their (Kinvey) backend API interface and it works fine in filtering the results so the problem definitely lies within PAW. I am currently using version 3.0.9. Any suggestions or is this just a bug that needs to be fixed?
Thanks!
I've just tried this setup in Paw and I have a few recommendations:
Paw will URL-encode the chars { and " as you can see if you open the HTTP preview in the bottom panel
Trying to send a similar query via Chrome (to test with another app to make sure Paw behaves correctly), I see that the query is URL encoded (try this query https://echo.paw.cloud/?query={"firstName":"James"} you'll see that the browser actually URL-encodes the characters { and " when sending. So the behavior is the same with Paw.
I don't think these two chars ({ and ") are valid HTTP if they are not URL-encoded, so I'm sure your server is expecting them encoded anyway
Testing this exact query in Paw, works for me, so please try these exact steps: go to URL Params, in the first column enter query and {"firstName":"James"} in the second column. Then using the HTTP preview mentioned above, make sure Paw is sending the request you're expecting.
Lastly, it's more like a tip, but as your value is JSON, I recommend that you use the JSON dynamic value to generate the JSON. It will be visually better for you, and will make sure you send valid JSON. For that, right click on the value field, and select Values > JSON. Here's some example:

Elm - retrieving string via get request

I am trying to make a get request to retrieve a string
When I use
retrieve : Task.Task Http.Error String
retrieve = getString "http://api.endpoint.com"
everything works fine.
On the other hand if I use
retrieve : Task.Task Http.Error String
retrieve = get Json.Decode.string "http://api.endpoint.com"
the http request gets done, but the chained tasks are not executed.
My question is: what is the difference between the two approaches above? Am I doing something wrong with the second one? How to debug it?
getString returns the response of the get request as a String. get take a JSON decoder and runs that over the response of the get request. So if you provide Json.Decode.string, it will expect the response to be have a Json encoded string in it. So it expects extra double quotes in the response.
If your http request fails the best way to debug is to look at what kind of error you get. In this case you'll probably get an UnexpectedPayload because the request succeeds, but the decoder fails.

JMeter "forgets" variable value defined via Regular Expressioin Extractor

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.
