I want to re-use the Response Data received in Listener as show in Image below.
I would like to know, how can I capture overall response so that I can re-use the same for uploading.
Scenario is:
Download 1KB of string data using TCP Sampler (Port: XYZW)
Upload the text response received (Port: ASDF)
As per How to Extract Data From Files With JMeter the relevant Regular Expression should be:
(?s)(^.*)
Entire configuration:
With Http sampler, I add a BeanShell PostProcessor as a child of Http sampler and use below script to retrieve all response data, I think it's the same with TCP sampler, let's try:
// get all response data
String dashboardData = prev.getResponseDataAsString();
// do something with the data
// and then put the retrieved data into parameter to use later
vars.put("dataTobeUsed", dashboardData);
and we can use ${dataTobeUsed} for other samplers
If you want to get the response data via regular expression extractor, you can use the pattern ([^"]+)
Hope it's helpful!
Hope I understood your question right,
You can use regular exp [a-z0-9]* with any reference name lets say "TCP_Data" in your first TCP request.
Now you can use the same reference name in TCP request 2, by ${TCP_Data}.

I am currently using some website to read some useful data. Using the browser's Inspect>Network I can see this data comes from JSON RPC requests to (https://bsc-dataseed1.defibit.io/) the public available BSC explorer API endpoint.
This requests have the following format:
Request params:
{"jsonrpc":"2.0","id":43,"method":"eth_call","params":[{"data":"...LONGBYTESTRING!!!","to":"0x1ee38d535d541c55c9dae27b12edf090c608e6fb"},"latest"]}
Response:
{"jsonrpc":"2.0","id":43,"result":"...OTHERVERYLONGBYTESTRING!!!"}
I know that the to field corresponds to the address of a smart contract 0x1ee38d535d541c55c9dae27b12edf090c608e6fb.
Looks like this requests "queries" the contract for some data (but it costs 0 gas?).
From (the very little) I understand, the encoded data can be decoded with the schema, which I think I could get from the smart contract address. (perhaps this is it? https://api.bscscan.com/api?module=contract&action=getabi&address=0x1ee38d535d541c55c9dae27b12edf090c608e6fb)
My goal is to understand the data being sent in the request and the data given in the response so I can reproduce the data from the website without having to scrape this data from the website.
Thanks.
The zero cost is because of the eth_call method. It's a read-only method which doesn't record any state changes to the blockchain (and is mostly used for getter functions, marked as view or pure in Solidity).
The data field consists of:
0x
4 bytes (8 hex characters) function signature
And the rest is arguments passed to the function.
You can find an example that converts the function name to the signature in this other answer.
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.
How can I Parameterize an http call parameter in soapui to read parameters from a txt file for each iteration.
If needed can the parameters be encoded(url or gzip) before the call was sent?
Any help (pointers/links/code) is greatly appreciated? Thank You
Use groovy script test step to read data from txt file and store the data in TestCase property .
Something like this would work:
String fileContents = new File('/path/to/file').text;
testRunner.testCase.setPropertyValue(property_name, fileContents);
More information about groovy script steps here.
You can access this property as ${#TestCase#property_name} in your requests. Then you can use template parameters for your request url - I've already answered about it here.
If i'm not wrong you are asking about parametrization of URL which you send as HTTP Request for your Rest call. Let me explain you with an example :
Suppose you are looking for a resource and invoking the WebService using the GET method by making use of the ResourceID already present in the DB...Parametrize it as below :
http://${#Project#HOST}:${#Project#PORT}/rest/${#Project#WebApplicationName}/Resource/${#TestCase#ResourceID}
where HOST, PORT, WebApplicationName are the Project Level properties and ResourceID is a Test Case Level property(as it may change with the test cases i.e., dynamic in nature).
This is my approach of parametrization instead of taking it from a local file. Hope this helps!
I am working on an app where we have to pass specific web api parameters to a web app using HTTP POST.
eg:
apimethod name
parameter1 value
parameter2 value
So do I use a string or URLEncodedPostData to send that data?
It would be good if u help me with a code eg.
I am using something like this but it doesnt post the data to the server.
Though the response code is ok/200 and I also get get a parsed html response when i read the httpresponse input stream. But the code doesnt post anything. So unable to get the expected response.
_postData.append("method", "session.getToken");
_postData.append( "developerKey", "value");
_postData.append( "clientID", "value");
_httpConnection = (HttpConnection) Connector.open(URL, Connector.READ_WRITE);
String encodedData = _postData.toString();
_httpConnection.setRequestMethod(HttpConnection.POST);
_httpConnection.setRequestProperty("User-Agent", "BlackBerry/3.2.1");
_httpConnection.setRequestProperty("Content-Language", "en-US");
_httpConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
_httpConnection.setRequestProperty("Content-Length",(new Integer(encodedData.length())).toString());
os = _httpConnection.openOutputStream();
os.write(requeststring.getBytes());`
The code you posted above looks correct - although you'll want to do a few more things (maybe you did this already but didn't include it in your code):
Close the outputstream once you've written all the bytes to it
Call getResponseCode() on the connection so that it actually sends the request
POSTed parameters are usually sent in the response BODY, which means URL-encoding them is inappropriate. Quote from the HTTP/1.1 protocol:
Note: The "multipart/form-data" type has been specifically defined
for carrying form data suitable for processing via the POST
request method, as described in RFC 1867 [15].
The post method allows you to use pretty arbitrary message bodies — so it is whatever format the server wants.
I am creating a HTTPS connection and setting the request property as GET:
_httpsConnection = (HttpsConnection) Connector.open(URL, Connector.READ_WRITE);
_httpsConnection.setRequestMethod(HttpsConnection.GET);
But how do I send the GET parameters?
Do I set the request property like this:
_httpsConnection.setRequestProperty("method", "session.getToken");
_httpsConnection.setRequestProperty("developerKey", "value");
_httpsConnection.setRequestProperty("clientID", "value");
or do I have to write to the output stream of the connection?
or do I need to send the Parameter/Values by appending it to the url?
Calling Connection.setRequestProperty() will set the request header, which probably isn't what you want to do in this case (if you ask me I think calling it setRequestHeader would have been a better choice). Some proxies may strip off or rewrite the name of non-standard headers, so you're better off sticking to the convention of passing data in the GET URL via URL parameters.
The best way to do this on a BlackBerry is to use the URLEncodedPostData class to properly encode your URL parameters:
URLEncodedPostData data = new URLEncodedPostData("UTF-8", false);
data.append("method", "session.getToken");
data.append("developerKey", "value");
data.append("clientID", "value");
url = url + "?" + data.toString();
HTTP GET send data parameters as key/value pairs encoded within URL, just like:
GET /example.html // without parameters
GET /example.html?Id= 1 // with one basic parameter
GET /example.html?Id=1&Name=John%20Doo // with two parameters, second encoded
Note follow rules for character separators:
? - split URL in two pieces: adddress to left and paremeters to right
& - must be used to separate on parameter from another
You must know your platform specific native string encode function. Javascript uses escape, C# uses HttpUtility.UrlEncode
Yep, headers and properties are pretty much all you can send in a GET. Also, you're limited to a certain number of characters, which is browser dependent - I seem to recall about 1024 or 2000, typically.
