I am recording Login in Jmeter. Password has '#'. Jmeter recorded exact string but when i run the same, '#' is converted to '%40ss' and login is getting failed(login is failing even if i pass parameters through csv file). But if we pass parameters through jmeter Body Data, Login is successful. I dont want to pass through Body Data, i want to send parameters through CSV file. How to achieve this. Please find the attachments
Recorded and Response
My expectation is that it is only a matter of representation, i.e. when I run similar request using a sniffer tool like Wireshark I can see # sign as a part of form data.
Most probably your problem lies somewhere else, i.e. you haven't correlated this __RequestVerificationToken or haven't added HTTP Cookie Manager.
When it comes to load testing ASP.NET web applications you cannot just record and replay your test, you need to perform correlation of dynamic parameters, check out ASP.NET Login Testing with JMeter article for more details.
Lakshmikanth, when you are passing any special character in parameters values then JMeter converts that character into percent-encoding for eg. '#' converts to '%40', '!' converts to '%21'.
To overcome this issue you can pass your password as it is [say P#ssword] in the .csv file but in your request you need to uncheck the encode checkbox corresponding to your password parameter.

We have one URL parameter as "code_challenge" which gets generated at run time, this value we need to extract so that from next runs it can be handled. However since this code value is not captured in any previous requests/responses and need to extract at run time, unable to understand how to achieve.
Tried Regular Extractor choosing URL radio button, but it captures the value from recorded script.
Steps followed:
Record script using Blazmeter (Browse URL xx.com>Click Login)
Redirected to URL(s) in which one of the url has "code_Challenge" parameter with run time value)
First URL is: accounts-xx.com/oauth2/oidcdiscovery/.well-known/openid-configuration> The response doesn't have any parameter values
Second URL is:
https://accounts-xx.com/oauth2/authorize?response_type=code&client_id=zzzz&scope=ituytutut&redirect_uri=xx.com/callBack&code_challenge_method=ooo&**code_challenge=dsfsdlfhl**
In above 3rd point url, Code_challenge value is generated at run time when executed steps from browser.
However If replayed the recorded script which would have already generated code value hence other requests would fail. Due to this, need to get the code value fetched.
The code_challenge is generated from WS02 service.
Jmeter version: 5.3
Please suggest, or should we need to use Selenium webdriver integration.
Regular expression which would extract the value from recorded script:
As per Mitigating Authorization Code Interception Attacks article:
code_challenge The client creates and records a secret cryptographically random string (the code_verifier), which is then encoded using URL safe base64 encoding to transform it into the code_challenge.
As per PKCE in WSO2 IS server article:
1.Plain:
If a code_challenge method is mention as plain or not mention at all it will take this plain value. Then code_challenge will like:
code_challenge = code_verifier
2. SHA256:
To have the code_challenge as SHA256, we should mention this in request otherwise plain value will be assumed.For SHA256 code challenge will be like
code_challenge = BASE64URL-ENCODE(SHA256(ASCII(code_verifier)))
Here base64url is same as base64encoding(used so that all machine can identify as same value) but trailing “=” will be removed and “+” & “/” are placed by “-” & “_” to avoid unnecessary length in URL.(otherwise ‘+’ becomes ‘%2B’, ‘/’ becomes ‘%2F’ and ‘=’ becomes ‘%3D in URL)
As much as possible, it is better to select the code challenge method as SHA256 then the flow will become more secure and hard to guess(if someone try to brute force it)
So I think you need to add JSR223 PreProcessor and calculate/generate the code_challenge using the algorithm used by your server in Groovy language, store the value into a JMeter Variable and use it in the request.
You can leave the field value empty and then its value gets updated once the request is sent. But you won't see the value in the request.
I had a similar issue, it worked in my case.
I need to load test one Python api in below URL format:
//IP:PORT/Sub_Part/?where={"KEY1":"VALUE1","KEY2":"VALUE2","KEY3":"VALUE3"}
I tried to pass the key value pair through csv as well as directly in http request but getting error message.
java.net.URISyntaxException: Illegal character in query at index 47:
http://IP:PORT/Sub_Part/?where={"KEY1":"VALUE1","KEY2":"VALUE2","KEY3":"VALUE3"}
Here key and value are dummy data I have placed here for easy understanding.
Please help me with correct syntax for this URL.
Thanks in advance for all your help.
In REST APIs, JSON objects are typically sent (POST) or returned in the body of the request. They are not typically encoded as part of the URL.
For a GET request, you can either pass the information as segments in the url or as querystring parameters.
For more details refer here, How to send a GET request with a "/" in the query
As per HTML URL Encoding Reference:
URLs can only be sent over the Internet using the ASCII character-set.
so you need to define the request in JMeter's HTTP Request sampler as follows:
Pay attention to URL Encode? checkbox, it has to be ticked otherwise the parameter will be sent "as is"
Another option is using __urlencode() function like:
http://IP:PORT/Sub_Part/?where=${__urlencode({"KEY1":"VALUE1"\,"KEY2":"VALUE2"\,"KEY3":"VALUE3"})}
which will generate an encoded sequence which you could use in the URL path:
%7B%22KEY1%22%3A%22VALUE1%22%2C%22KEY2%22%3A%22VALUE2%22%2C%22KEY3%22%3A%22VALUE3%22%7D
as you can see, all non-ASCII characters where removed.

When I wish to login as "pieraś", the page detects login "pieraĹ"
I tried selecting "URL ENCODE", changing jmeter.property csvdataset.file.encoding_list to "ISO 8859-2" only as well ass UTF-8 only.
JMETER request picture
How to make it work right?
In the HTTP request field "Content Encoding:" manually enter value "ISO-8859-2".
It works against jmeter.property "sampleresult.default.encoding"
I tried to use "pieraś" in jmeter, looks like JMeter is passing and processing this value properly. Some sample snap given below:
I'm trying to create a simple stress test using JMeter. I have mostly GET requests and a couple POST requests. My main goal is to make this test as reusable as possible. I want to implement it in a way that the user would have to provide a CSV file with the following headers:
method;path;postBody
The values would look something like:
GET;/path/to/resource;''
POST;/path/to/resource;'{"key":"value","key":"value","key":"value"}'
Now POST (PUT, PATCH etc ..) bodies differ from one request to another. Providing ${postBody} to Body Data tab does not work "${postBody}" as well.
Is there a way to achieve this? Command line solutions are more than welcome as well.
EDIT: To clarify, I'm using the UI interface. When I input ${postBody} in the Body Data tab the UI complains. When switching from the Body Data tab to another one I get the following prompt:
Remove "'" around the request and it should work.
Regarding the warning you get, it is not an error, it is just that in JMeter those 2 tabs are exclusive:
Parameters tabs is for input of parameters in the form as name=value
Body data is for your kind of requirement
So can you test my hypothesis which is to remove the quote around the request in CSV file ?
If it still fails, please show the logs.
You can remain in Body Data tab,
Add after pathPost your optional query parameters for GET request:
${pathPost}?${getPramaters}
Don't worry about the ? it's just seperate path from parameters
Also consider changing variable name to path, more suitable because it can be POST.
In JSON , seperate between values while in CSV default is also ,
I suggest you can your CSV delimiter, In CSV Data Set Config Choose different Delimiter as ; and add your data in CSV accordingly (remove extra ' characters):
POST;/path/to/resource;{"key":"value","key":"value","key":"value"}
Notice: Allow quoted data keep default value False
How to parameterize request if I am getting something similar to the following for login POST request in body data tab.
"{\"msg\":\"method\",\"method\":\"login\",\"params\":[{\"user\":{\"username\":\"testuser\"},\"password\":{\"digest\":\"5811c74a581ffdb892ab9eddfb9cf2d21772a98332a59de6aa26989e01f84057\",\"algorithm\":\"sha-256\"}}],\"id\":\"7\"}"]
It's generally easy to correlate when we are getting in Parameters TAB, but in cases how we can proceed? For all further requests - it's the similar case.
I tried to switch to Parameters TAB, but it says that it can not be converted to that format.
So How we can proceed?
The same way, just substitute hard-coded (recorded) values with the relevant JMeter Variables directly in the request body like:
"{\"msg\":\"method\",\"method\":\"login\",\"params\":[{\"user\":{\"username\":\"${username}\"},\"password\":{\"digest\":\"${password}\",\"algorithm\":\"sha-256\"}}],\"id\":\"${id}\"}"]
The most commonly used for parameterization test element is CSV Data Set Config, however other options exist.
