I'm trying to send the following (literal) text in a request body in Postman:
{
"message": "Hi {{USERNAME}} your code is {{CODE}}"
}
However, in my Postman environment I have a USERNAME variable, so Postman is substituting in the variable value and the following hits my backend (note that I don't have a CODE variable in Postman):
{
"message": "Hi username_value_in_postman your code is {{CODE}}"
}
So I'm looking for a way to escape or ignore the Postman variable syntax so that it sends the literal string. I've searched the docs and SO, but didn't find anything useful for my problem, so any help would be appreciated.
Escaping doesn't seem to work, so I guess you'd either need to rename your variable(s) or use Pre-request and Tests scripts:
In Pre-resuqest script, you can write this code:
pm.variables.set('usernameBackup', pm.variables.get('USERNAME'));
pm.environment.unset('USERNAME');
And you set the environment variable again in the Tests script:
pm.environment.set('USERNAME', pm.variables.get('usernameBackup'));
pm.variables.unset('usernameBackup');

I have an environment variable in the Request URL as https://api-{{environment}}.{{domain}}.com/api/ , how can I use them in sending requests from scripts ?
'https://api-("environment").("domain").com/api/ doesnt work , Any helps please
you can use pm.environment.get('environmentvaraiblename') to access the value of a vaeraible inside script
you can call it within the string using string literal in java script or just concatenate using +
`https://api-${pm.environment.get("environment")}.${pm.environment.get("domain")}.com`
note that the quote is not single quote (') but (`)
I'm trying to add a JMeter backend listener to my JMeter project so I can have all the metrics in real-time in Graphite. My tests run distributed on several nodes and I want to know the hostname in as part of the graphite path. I tried to incorporate JSR223 scripts, but those are not evaluated before the listeners start, so I used the __groovy() method for the rootMetricsPrefix field, like this:
${__groovy(vars.get(vars.get("environment")+".graphiteprefix"))}.server.
${__groovy(InetAddress.getLocalHost().getHostName()
.replaceAll(/^([^.]*).*$/){m,host->return host})}.
myappbucket.jmeter.
The first part gets the variable with the name "environment" to get the root prefix for the environment ("test", "load", etc). The seconds __groovy() script should get the first part of the hostname. It works if I add it as a JSR223 sampler (to test it), but if I try to use it as a variable, I get the following error:
Script13.groovy: 1: expecting '}', found '' # line 1, column 67.
me().replaceAll(/^(^\.).*$/){m
^

According to JMeter documentation:
If a function parameter contains a comma, then be sure to escape this with "\", otherwise JMeter will treat it as a parameter delimiter. For example:
${__time(EEE\, d MMM yyyy)}
So you need to escape the comma between m and host
${__groovy(InetAddress.getLocalHost().getHostName() .replaceAll(/^(^\.).*$/){m\,host->return host})}. myappbucket.jmeter.
Also be aware of __machineName() and __machineIP() functions, they provide a little bit easier way of getting the hostname and IP address of the JMeter Engine. See Apache JMeter Functions - An Introduction article for more comprehensive information on JMeter Functions
When request extracts a URL variable from XML document through XPath Extractor and Regular Expression Extractor it decodes the encoded characters in the extracted URL.
For example, the URL in the XML file:
<url>www.testing.com/test/request?parameter1=test1¶meter2=test2</url>
The & between the two URL parameters become & which affect my testing final results.
Is there any way to prevent special characters decoding in JMeter?
Normally JMeter should not perform encoding and decoding of variables during extraction, the variable should be sent as is so most probably something is wrong with your test logic. You can double check the variable value using Debug Sampler and View Results Tree listener combination. See How to Debug your Apache JMeter Script article for more information on JMeter tests troubleshooting.
As a workaround you can explicitly tell JMeter to encode the variable using __escapeHtml() function like:
${__escapeHtml(${your_variable_here})}
I have occur a problem when using postman. In postman, the brace {} means to use environment variable. But I post something like https://www.google.com/{xxxxx}, now the brace need to be used in url, not for environment variable. So how can I avoid this conflict?
{ and } are reserved characters and can't be used in the path of a URL (see RFC 3986). They should be url-encoded, and this is what some http libraries do silently.
You should replace { by %7B and } by %7D, so your URL would look like: https://www.google.com/%7Bxxxxx%7D
If you want more information about the encoding of ASCII characters, you can find a simple table here.
Working on one of the tasks i am using jsstringformat function to handle json data if some special characters are used, but that does not seems to handle all issues.
My JSON still breaks.
I am using like this :
"<a href='edit.cfm?id=#jsStringFormat(qFiltered.randomnumber)#' style='color:##066D99'>#trim(jsStringFormat(qFiltered[thisColumn][qFiltered.currentRow]))#</a>"
I am lost here what else i can use as any part of regex or rereplace that it should not break
Thanks
You're doing multiple things here.
You're putting the string into a URL: use UrlEncodedFormat.
You're also putting it in an HTML tag: use HtmlEditFormat.
The whole thing is going into a JavaScript variable, so I would use JSStringFormat to wrap the whole thing.
Try building your string before assigning it.
<cfsavecontent variable="htmlLink"><cfoutput>
#HtmlEditFormat(Trim(qFiltered[thisColumn][qFiltered.currentRow]))#
</cfoutput></cfsavecontent>
myJsVar = "#JsStringFormat(Trim(htmlLink))#";
