How to send multiple JSON's as payload for a HttpRequest from a csv or text file.

[xara...@gmail.com]

Hi All,

Can someone help me on how to send  multiple JSON's as payload for a HttpRequest from a csv or text file. I'm doing some API Perf testing, where I want to send multiple json's(diff json for diff use cases) as message body for the API request.

I tried by putting the json's in an in-formatted way with one json in one line and next in next line like which I have multiple jsons/lines in a text file, and I'm reading this file using CSV Data Config and trying to put the  variable name as Request payload.

When the script starts running getting the below exception,

{"httpStatus":503,"serviceId":0,"errorCode":"ITEM50000","debugMessage":"JSON parse error: Unexpected end-of-input: expected close marker for Object (start marker at [Source: (PushbackInputStream); line: 1, column: 1]); nested exception is com.fasterxml.jackson.core.io.JsonEOFException: Unexpected end-of-input: expected close marker for Object (start marker at [Source: (PushbackInputStream); line: 1, column: 1])\n at [Source: (PushbackInputStream); line: 1, column: 51]","messageArgs":{}}

Can some one please help on this.

The easiest solution is:

1. Put each JSON into a separate file
2. Use Directory Listing Config plugin to read the files into a JMeter Variable 
3. Use __FileToString() function in the HTTP Request sampler body data to read the file from the directory.

Hi Thanks... even I thought the same. I'm going to do the same by send each JSON as a file using  __FileToString() function  rather than a variable. 

Can you please tell is there a way to get response for each diff json request...rather than a single report for overall requests.
