I have a simple request which has an input in string format, having special char (quotes-dash-hash) etc
While executing this request I am getting "Bad Request" error.
I've tried setting up HTTP Header manager (content type) to 'application/json;charset=UTF-8'. But didn't work.
Can someone please help?
Note: Actually, all the random song names fetched from CSV. Where 'normal song names' and 'song names having special char' string values are stored in column. So already tried 'all quoted data: true' as well in CSV Data Set Config.
My CVS looks like this:
Songname
Jack "50 Cent" Maddy: paul
Michael Jackson
Sean Paul
Nachi "TO infor"
Aln!!! E i Chips
Post req: /api/check/song?username=User8001
Header:
Content-Type application/json;charset=UTF-8
Accept application/xml;charset=UTF-8
Post body:
{
"search": {
"song": "${songname}",
},
"year": 2016
}
It's hard to come up with the comprehensive solution without seeing your source data from the CSV file and how you're building your HTTP Request sampler.
You're getting error because in JSON string literals you need to escape quotation marks with the backslash.
If this is something you cannot do in the CSV source data you could consider using i.e. StringEscapeUtils.escapeJavaScript() from the __groovy() function like:
${__groovy(org.apache.commons.lang.StringEscapeUtils.escapeJavaScript(vars.get('varFromCSV')),)}

The background is that I want to make a REST to Google pub/sub. Where the data need to follow this format:
Link to documentation of Pub/Sub format
My current solution is that I uses an BeanShell PreProcessor script to encode the payload to base64 before I send the request to the endpoint. This solution works, but I would like to
parameterize the data in the payload, instead of having the whole payload inserted as test data in the csv-file.
BeanShell PreProcessor used to encode the message before it is being sent:
import org.apache.jmeter.protocol.http.util.Base64Encoder;
String csv_payload = vars.get("csv_payload");
String csv_payload_encoded = Base64Encoder.encode(csv_payload);
vars.put("csv_payload_encoded", csv_payload_encoded);
Payload populated from the csv-file in Post request:
{
"messages": [
{
"data":"${csv_payload_encoded}",
}
]
}
Example of payload data stored in the csv-file that is sent in the request:
{"identId":"123456","requestId":null,"payload":{"header":{"requestid":1,"timeStamp":1617873956,"version":"0.0.0.1","eventId":0001,"creatorId":0,"messageTTL":34560},"body":{"checkid":001,"checkData":{"diagnosticsData":{"troubleSource":0,"data":"[2020-01-01 16:00:53.707961][[lat[0]][long[0]][alt[0]][canbetrust[0]][mars[0]]][signal[5]][TEM2 wake up]"}}}}}
Example of the encoded payload that the request sends to google pub/sub:
{
"messages": [
{
"data":"eyJpZGVudElkIjoiMTIzNDU2IiwicmVxdWVzdElkIjpudWxsLCJwYXlsb2FkIjp7ImhlYWRlciI6eyJyZXF1ZXN0aWQiOjEsInRpbWVTdGFtcCI6MTYxNzg3Mzk1NiwidmVyc2lvbiI6IjAuMC4wLjEiLCJldmVudElkIjowMDAxLCJjcmVhdG9ySWQiOjAsIm1lc3NhZ2VUVEwiOjM0NTYwfSwiYm9keSI6eyJjaGVja2lkIjowMDEsImNoZWNrRGF0YSI6eyJkaWFnbm9zdGljc0RhdGEiOnsidHJvdWJsZVNvdXJjZSI6MCwiZGF0YSI6IlsyMDIwLTAxLTAxIDE2OjAwOjUzLjcwNzk2MV1bW2xhdFswXV1bbG9uZ1swXV1bYWx0WzBdXVtjYW5iZXRydXN0WzBdXVttYXJzWzBdXV1bc2lnbmFsWzVdXVtURU0yIHdha2UgdXBdIn19fX19",
}
]
}
If there are any feedback I would appreciate it or any other improvements suggestion
for how I would be able to proceed in order to parameterize and encode the payload to base64 eg:
Example of
Don't use Beanshell, since JMeter 3.1 you're supposed to be using JSR223 Test Elements and Groovy language for scripting
There is __base64Encode() function available via Custom JMeter Functions plugin bundle installable using JMeter Plugins Manager
If you CSV file has references to other JMeter Functions or Variables you can resolve them by wrapping into __eval() function like:
to read the file:
${__FileToString(somefile.csv,,)}
to read the file and resolve any functions or variables in it:
${__eval( ${__FileToString(somefile.csv,,)})
to read the file, resolve any functions or variables and Base64-encode the result:
${__base64Encode(${__eval( ${__FileToString(somefile.csv,,)})},)}

I'm trying to solve a test data issue in Jmeter. Can anyone of you have a look at below problem statement and advise here please ?
Requirement: Need to send all entries in a CSV file to HTTP request body in 'one' request to the end point.
Example CSV File:
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d"
HTTP Request Body:
["${data}"}]
When the data is substituted, I should be able to get below output.
[
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d"
]
Problem Statement: When I use CSV data set config. file, I'm unable to concatenate all entries into one single request body. My understanding is, CSV data set config. the file is not the right option here.
Did some search in StackOverflow and followed a method to achieve above using JSR223 PreProcessor' and the link is, How to send multiple json body using jmeter?.
Followed the above link and tried added below custom code provided.
def builder = new StringBuilder()
new File('/path/to/plans.csv').readLines().each { line ->
builder.append(new File(line).text).append(System.getProperty('line.separator'))
}
sampler.getArguments().removeAllArguments()
sampler.addNonEncodedArgument('', builder.toString(), '')
sampler.setPostBodyRaw(true)
Upon running, I get below error message,
Caused by: java.io.FileNotFoundException,
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d" (The filename, directory name, or volume label syntax is incorrect)
If the file is not found, then how come the entries are read and displayed in the log viewer?
Also, how do I link the output of custom code to the request body? Or is it taken care of by the custom code itself?
You have an error in your code, change this line:
builder.append(new File(line).text).append(System.getProperty('line.separator'))
to this one:
builder.append(line).append(System.getProperty('line.separator'))
If you want to send the full contents of the file you don't even need to go for scripting, you can use __FileToString() function right in the "Body data" tab of the HTTP Request sampler:
${__FileToString(/path/to/plans.csv,,)}
And last but not the least if you need to generate JSON from the plain text it might be a better idea to go for JsonBuilder class, see Apache Groovy - Why and How You Should Use It and Apache Groovy - Parsing and producing JSON
Two steps:
Add a User Parameter Pre-processor before the HTTP request:
Name: DATA
User_1: ${__FileToString(/path/to/plans.csv,,)}
Add the following to request body:
${DATA}
I need to load test one Python api in below URL format:
//IP:PORT/Sub_Part/?where={"KEY1":"VALUE1","KEY2":"VALUE2","KEY3":"VALUE3"}
I tried to pass the key value pair through csv as well as directly in http request but getting error message.
java.net.URISyntaxException: Illegal character in query at index 47:
http://IP:PORT/Sub_Part/?where={"KEY1":"VALUE1","KEY2":"VALUE2","KEY3":"VALUE3"}
Here key and value are dummy data I have placed here for easy understanding.
Please help me with correct syntax for this URL.
Thanks in advance for all your help.
In REST APIs, JSON objects are typically sent (POST) or returned in the body of the request. They are not typically encoded as part of the URL.
For a GET request, you can either pass the information as segments in the url or as querystring parameters.
For more details refer here, How to send a GET request with a "/" in the query
As per HTML URL Encoding Reference:
URLs can only be sent over the Internet using the ASCII character-set.
so you need to define the request in JMeter's HTTP Request sampler as follows:
Pay attention to URL Encode? checkbox, it has to be ticked otherwise the parameter will be sent "as is"
Another option is using __urlencode() function like:
http://IP:PORT/Sub_Part/?where=${__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.

i am unable to provide request to the server in json format using parameters so please can anyone explain me about it?
I sent this request from Bodydata extracting data from CSV:
POST data:
{
"password":"login",
"username":"568592"
}
but when i used parameters for extracting data from CSV:
POST data:
password=login&username=568592
How can i send json format request using parameters?
There should be no difference given you properly pass your JSON via "Parameters" section.
If you want to use "Parameters" - just put your JSON payload into "Value" section of the 1st parameter like:
If you want to use "Body Data" - put your JSON Payload there (don't forget to remove everything from the "Parameters" section)
Don't forget to add HTTP Header Manager to send Content-Type header with the value of application/json
I need to pass a data from a json response to the subsequent request's Post Body data however it is not working, something is going wrong.
First request returns the JSON in response body which looks like this:
"accessToken":[{"idToken":"eyJ05C3RU","token":"159c82d30ec3123e873ab989cc"}]
0000000
I have to extract 'accessToken' value to pass it to the next request's post bodydata (not under parameter tab of the request, it has to pass to BodyData tab of the next request)
I have created to JSON path extractors for the first request where getting response data with these values.
1JSON path extractor: $..accessToken[0].idToken
passed this in json path expression:$..accessToken[0].idToken
in the request of next request: { "idtoken": ${idToken}}
view results in tree:
shows post data as request:
POST data:{ "idtoken": ${idToken}}
response data:
omething broke!SyntaxError: Unexpected token $
at `Object.parse (native)`
Please help to resolve the issue. it will be really helpful.
Most likely your JSON Path expression is wrong or response isn't valid JSON.
You can fall back to Regular Expression Extractor which is not that handy, but will work for any text response, the relevant configuration would be:
Apply to: same as for JSON Path extractor
Reference name: idToken
Regular Expression: "idToken"\s?:\s?"(.+?)"
Template: $1$
Demo:
Reference material:
JSON Path Getting Started - if you want to continue with the JSON Path Extractor (double check that your response is a valid JSON using i.e. http://jsonlint.com/)

Thanks for all the help. I am able to overcome my issue by using JSON path expression extractor in the next request body as "idtoken": "${idToken_1}".
