How to get URL having ".../?where={'key1' : 'value1' , 'key2' : 'value2':.........}" in Jmeter http request

Question

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.

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.
