How to copy a pdf file content into a variable and then upload it as a multipart/related API request using JMeter??
In order to read the file inline or save it into a JMeter Variable people normally use __FileToString() function however it might not work for PDF files because they're binary so you might want to additionally convert it into Base64, the __base64Encode() can be found in Custom JMeter Functions bundle which in its turn can be installed using JMeter Plugins Manager
In general I would suggest recording your file upload request using JMeter's HTTP(S) Test Script Recorder, just remember to copy the PDF file you will be uploading to "bin" folder of your JMeter installation otherwise JMeter will fail to capture the request properly.

Im trying to upload file and sending few parameters in the request but it looks it is not taking file path
-- payload
{"id":70,"student_id":24,"uploaded_by": "dbhadauria#concertai.com","document_name":"test","document_type":".png","files":
"CG.png"}
I m trying to give exact path also like C:/Files?CG.png but it is not working.
Normally you need to provide the file path and its MIME type under Files Upload tab of the HTTP Request sampler
If you're uncertain regarding how to properly build the file upload request you can just record it using JMeter's HTTP(S) Test Script Recorder, just make sure to copy the file(s) you will be uploading to "bin" folder of your JMeter installation, this way JMeter will be able to properly capture the request and generate the HTTP Request sampler.

Your syntax is incorrect, the valid one for the __FileToString() function would be:
${__FileToString(${JSON_FILE},,)}
Consider using Functions Helper Dialog if you're uncertain
Your setup doesn't really "upload" the file, it sends the file as the HTTP POST body, the "upload" assumes either PUT or POST with multipart-form/data. Again if you're not sure that you're building the request correctly just record it using JMeter's HTTP(S) Test Script Recorder, just make sure that the file(s) you're uploading are present in "bin" folder of your JMeter installation
I need to do load test on a web application where images will be uploaded(Similar to the site https://imgbb.com/). I am unable to perform this. Can anyone help me out with this.
I have tried working it out but no luck. Please find the below screenshots for reference. Firstly after recording the script i have enhanced the script with correlation and have executed, then I have received the following error.
After doing some R&D, I have made certain changes(Implementation from default to HttpClient4, and Request parameters to Body Data) and executed again, still no luck.
Changes Made

Can someone please suggest now
You're doing something very weird. The easiest way to create a file upload request using JMeter is just recording it using JMeter's HTTP(S) Test Script Recorder
Start JMeter's HTTP(S) Test Script Recorder
Import ApacheJMeterTemporaryRootCA.crt file into your browser (it is required as imgbb.com is using HTTPS protocol and JMeter will need MITM certificate in order to be able to decrypt and record secure traffic)
Copy the file you'll be uploading into "bin" folder of your JMeter installation (otherwise JMeter will not be able to find it)
Perform upload request in the browser - JMeter will capture it under Recording Controller
See Recording File Uploads with JMeter article for more details.
Just in case if you want or need to build the request manually the relevant HTTP Request sampler configuration should look like:
Parameters tab:
Files Upload tab
You should see the following output in the View Results Tree listener:
To upload files from JMeter Http sampler you have to add file path to http sample and corresponding mime type..
Open Files to upload tab in the HTTP sampler enter the file path ..
If the file is in JMeter's bin directory you can give relative path , if the file resides somewhere on the disk give absolute path and enter corresponding mime type
You can find mime type here.

I am searching for an option so that I can send audio file with http request sampler without pasting content from audio file(makes script heavy).
If you switch to "File Upload" tab of the HTTP Request sampler you will be able to provide path to the file for uploading along with its MIME type and associated parameter name.
This way your test plan will contain only path to the file, not its content so the size of .jmx script will not be increased.
The easiest approach to build the file upload request is just recording it using JMeter's HTTP(S) Test Script Recorder, just make sure you copy the file(s) to "bin" folder of your JMeter installation so JMeter could capture the request and build the relevant HTTP Request sampler configuration. See Recording File Uploads with JMeter article for more details.
__FileToString()
We can do so by using __FileToString(File_path,Encoding_type) method.
I have a requirement to download zip file from server through JMeter to test the peroformance but for me the downloaded files are shown in x-filler, i need to have the zip file downladed.
Please help me here
Thanks in Advance
Simulating file download event using JMeter is as simple as sending HTTP GET request using HTTP Request sampler.
If you need to save the response somewhere for later reuse or analysis add Save Response to a file listener as a child of the request which performs the download. Check out Performance Testing: Upload and Download Scenarios with Apache JMeter article for comprehensive explanation.
Be aware that storing responses will cause huge disk IO overhead during the load test so I would recommend ticking Save response as MD5 hash box under "Advanced" tab of the HTTP Request sampler and use MD5Hex Assertion to compare the MD5 checksum of the response with some reference value.
To download any file, you need to extract it using Regular Expression Extractor.
Add the Regular Express Extractor to the request where you want to download and configure the fields as shown below. Use (?s)(^.*) as the expression to extract everything.
Add the Save Responses to a File sampler and configure the fields as shown below.
Execute the test plan. In the JMETER_HOME\bin\, you can see the zip file. Extract the zip file and validate.
The easiest way is to use your own code to download the file. The options are BeanShell Postprocessor or JSR223 Postprocesor.
I extracted file name from response header Content-Disposition, save it to varible, and the use variable for filename. Additional variable was defined on Test level, holding folder name where to save files.
