I'm calling a REST end point that is unfortunately very windows reliant and required the body of the return to have '\r\n' instead of the default '\n'. Is there any hooks in PAW that could allow me to write a search and replace before sending a request?
Thanks

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) :-)
I need to reuse value which is generated for my previous request.
For example, at first request, I make a POST to the URL /api/products/{UUID} and get HTTP response with code 201 (Created) with an empty body.
And at second request I want to get that product by request GET /api/products/{UUID}, where UUID should be from the first request.
So, the question is how to store that UUID between requests and reuse it?
You can use the Request Sent Dynamic values https://paw.cloud/extensions?extension_type=dynamic_value&q=request+send these will get the value used last time you sent a requst for a given request.
In your case you will want to combine the URLSentValue with the RegExMatch (https://paw.cloud/extensions/RegExMatch) to first get the url as it was last sent for a request and then extract the UUID from the url.
e.g
REQUEST A)
REQUEST B)
The problem is in your first requests answer. Just dont return "[...] an empty body."
If you are talking about a REST design, you will return the UUID in the first request and the client will use it in his second call: GET /api/products/{UUID}
The basic idea behind REST is, that the server doesn't store any informations about previous requests and is "stateless".
I would also adjust your first query. In general the server should generate the UUID and return it (maybe you have reasons to break that, then please excuse me). Your server has (at least sometimes) a better random generator and you can avoid conflicts. So you would usually design it like this:
CLIENT: POST /api/products/ -> Server returns: 201 {product_id: UUID(1234...)}
Client: GET /api/products/{UUID} -> Server returns: 200 {product_detail1: ..., product_detail2: ...}
If your client "loses" the informations and you want him to be later able to get his products, you would usually implement an API endpoint like this:
Client: GET /api/products/ -> Server returns: 200 [{id:UUID(1234...), title:...}, {id:UUID(5678...),, title:...}]
Given something like this, presuming the {UUID} is your replacement "variable":
It is probably so simple it escaped you. All you need to do is create a text file, say UUID.txt:
(with sample data say "12345678U910" as text in the file)
Then all you need to do is replace the {UUID} in the URL with a dynamic token for a file. Delete the {UUID} portion, then right click in the URL line where it was and select
Add Dynamic Value -> File -> File Content :
You will get a drag-n-drop reception widget:
Either press the "Choose File..." or drop the file into the receiver widget:
Don't worry that the dynamic variable token (blue thing in URL) doesn't change yet... Then click elsewhere to let the drop receiver go away and you will have exactly what you want, a variable you can use across URLs or anywhere else for that matter (header fields, form fields, body, etc):
Paw is a great tool that goes asymptotic to awesome when you explore the dynamic value capability. The most powerful yet I have found is the regular expression parsing that can parse raw reply HTML and capture anything you want for the next request... For example, if you UUID came from some user input and was ingested into the server, then returned in a html reply, you could capture that from the reply HTML and re-inject it to the URL, or any field or even add it to the cookies using the Dynamic Value capabilities of Paw.
#chickahoona's answer touches on the more normal way of doing it, with the first request posting to an endpoint without a UUID and the server returning it. With that in place then you can use the RegExpMatch extension to extract the value from the servers's response and use it in subsequent requests.
Alternately, if you must generate the UUID on the client side, then again the RegExpMatch extension can help, simply choose the create request's url for the source and provide a regexp that will strip the UUID off the end of it, such as /([^/]+)$.
A third option I'll throw out to you, put the UUID in an environment variable and just have all of your requests reference it from there.
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:
My URL is http://175.24.2.166/download?a=TOP#0;ONE=1;TWO2.
How should I encode the parameter so that when I print the parameter in the Servlet, I get the value in its entirety? Currently when I print the value by using request.getParameter("a") I get the output as TOP instead of TOP#0;ONE=1;TWO2.
You should encode it like this http://175.24.2.166/download?a=TOP%230%3BONE%3D1%3BTWO2 . There are a lot of the encoders in Java, you can try to use URLEncoder or some online encoders for experements
This is known as the "fragment identifier".
as mentioned in wiki
The fragment identifier introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.
the part after the # is info for the client. Put everything your client needs here.
you need to encode your query string.
you can use encodeURIComponent() function in JavaScript encodes a URI component.This function encodes special characters.
I've created an API for use on my website.
The API I made strips everything using mysql_real_escape_string then puts it into the database.
But the problem I'm having is the URL that my php scripts are using to access the API is cut short sometimes...
Which I have narrowed down to one of the parameters...
When its Ford Mondeo 22' the URL that is passed to simplexml_load_file is
http://mydomain.com/api/create.xml?api_number=brho15p6z1dhqwf5tsff&env=live&number=AJ20023232&title=Ford Mondeo 22'&image=http://mydomain.com/wp-content/uploads/2012/10/914955-150x150.jpg
but the API reports back the URL accessed as
http://mydomain.com/api/create.xml?api_number=brho15p6z1dhqwf5tsff&env=live&number=AJ20023232&title=Ford
If I remove the single quote then everything works fine, any idea how to correct this I suspect there's something I've overlooked when passing variables in the URL
It is the spaces in the "Ford Mondeo 22'" value that is causing the problem. You cannot have a spaces in the URL. You need to use escape characters. The encoded version of the parameter should be
Ford%20Mondeo%2022'
%20 is the escape character for space
I.e. the whole URL should read as follows:
http://mydomain.com/api/create.xml?api_number=brho15p6z1dhqwf5tsff&env=live&number=AJ20023232&title=Ford%20Mondeo%2022'&image=http://mydomain.com/wp-content/uploads/2012/10/914955-150x150.jpg
EDIT:
Your comment indicates that you use PHP. In PHP, you can use urlencode($foo) and urldecode($foo) to switch between the normal string and the encoding string.
