Jmeter how to get the dynamic parameter value in the path - http

JMeter path contents some dynamically generated value.
Eg
[HTTP Request]
[path-home/user?p=er3562]
This "p" value is dynamically generated.
I want to get this parameter value in the first HTTP request path.
This parameter value should pass through each HTTP request path.
I am new to JMeter. Please help me to solve this?

You need to extract it somehow and convert into a JMeter Variable for later reuse. JMeter provides several PostProcessors for extracting data from different responses types, in your case the most suitable one will be Regular Expression Extractor.
Add Regular Expression Extractor as a child of the request which returns that path-home/user?p=er3562 value
Configure it as follows:
Apply to: depending on where the "interesting" value lives, the most "safe" setting is Main sample and sub-samples
Field to check: depending on where the "interesting" value comes from, in the majority of cases it's Body but in your case it may be i.e. URL
Reference Name: anything meaningful, it is JMeter Variable name, if JMeter finds anything it will store the result in a variable named accordingly to this field. I.e. path-home
Regular Expression: Perl5-style regular expression, in your case it would be something like: path-home/user\?p=er(\d+)
Template: if you're looking to extract a single value it will be $1$
Refer extracted value as ${path-home} where required.
References and tips:
You can use Debug Sampler and View Results Tree listener combination to view JMeter Variable names and test regular expressions against actual response

Regular Expression Extractor failing in JMeter for asp.net web forms

Using JMeter, I'm attempting to log in to an asp.net web forms application. I recorded the login sequence to a *.jmx file, and now I'm attempting to extract the __VIEWSTATE, __VIEWSTATEGENERATOR and __EVENTVALIDATION hidden inputs using the Regular Expression Extractor post-processor.
In all 3 cases JMeter is extracting the name of the variable that I want to extract into (eg "${viewstate}") instead of the value I want to extract. Here is what the RequestBody looks like when I look at the ViewResults Tree and select "Text":
ReturnUrl=%2F&__VIEWSTATEGENERATOR=%24%7Bviewstategenerator%7D&__EVENTARGUMENT=&__VIEWSTATE=%24%7Bviewstate%7D&ctl00%24ContentPlaceHolder1%24Login1%24LoginButton.x=25&ctl00%24ContentPlaceHolder1%24Login1%24Password=MyPassword%21&ctl00%24ContentPlaceHolder1%24Login1%24LoginButton.y=4&__LASTFOCUS=&ctl00%24ContentPlaceHolder1%24Login1%24UserName=MyUserName&__EVENTTARGET=&__EVENTVALIDATION=%24%7Beventvalidation%7D
Oddly enough, if I select "RegExpTester" in the ViewResults Tree and test my regular expressions, all of them appear to work.
For example, here is what my __VIEWSTATE extractor looks like:
The Regular Expression is this bit of text:
name="__VIEWSTATE" id="__VIEWSTATE" value="(.+?)"
When I enter that expression into the RegExp Tester it finds it. The other 2 also work:
This is my first time using JMeter, I suspect I've got something in the wrong place.
Here is how my HTTP Request is set up:
Here is how the entire project looks:
Where do you expect these values to come from? You're missing one GET request which will open the login page, your test should not start from POST request.
Once you execute GET request - your Regular Expression extractors will capture viewstate and friends and you will be able to log in.
Also consider switching to CSS Selector Extractors as using regular expressions to parse HTML is not the best idea.
The relevant CSS Selector expression would be as simple as input[id=__VIEWSTATE], use value as the attribute. Similarly correlate remaining dynamic values. See ASP.NET Login Testing with JMeter article for more details if needed.

Using a substring of a return value in a subsequent request

I'm attempting to construct a series of Paw calls using the variables feature. I have one situation I'm unable to solve.
At authentication into the server I'm using, I get a JSON response, with one value that looks like this:
endpoint = "https://sub.something.com/thingone/thingtwo.php?token=sometoken&id=blahblah"
The endpoint portion "https://sub.something.com/" is then used as the base for subsequent calls, where a call might be "GET https://sub.something.com/data?id=123".
I don't want to hardcode the endpoint in Paw, as the endpoint will vary based on factors I can't predict at my end.
Is there a way to do basic string processing like this either in Paw, or by calling out to a shell script and using the return value of said script as a Paw variable?
That's doable using that RegExp Match dynamic value extension. Click on that previous link and hit Install Extension.
Type "Regexp" in the field you expect this value to be used. Pick Regexp Match from the completion results:
Then enter a regexp that matches your need, https?://[^/]+/? should be good:
I've put your example string in the screenshot above to show that it works, but you can instead put a "pointer" (Response Dynamic Value) to the response you want:
In the choices, pick Response Parsed Body if you want to parse a JSON or XML from the reponse. If the string is simply in plain text in the response body, pick Response Raw Body.
Once these steps are completed, you've got a working "Pointer" + "Parser" to the response that extract the part of the string you need. You can do the same operation with another regex for the token…
Tip: these dynamic value tokens can be selected like text and copy/pasted (Cmd+C/Cmd+V) :-)

Adobe DTM to set query string in eVar and sProp

So normally I would use the s.getQueryParam(); to parse out my URLs for query strings that I've been using.
s.eVar8=s.getQueryParam('cid,pid,eid',':');
s.prop28=s.getQueryParam('Role');
But since DTM has that all built into it, how would you really define that? I know I can set a page load rule using the campaign variable, but what if I have multiple parameters separated by ":"
www.domain.com?cid=blah1:blah2:blah3&pid=blah4:blah5:blah6&eid=blah7:blah8:blah9
Is there something that I'm missing when using this approach? Should I be capture these values into a data element then passing the data element into a page load rule using an eVar or sProp?
For variables that only look for a single URL parameter:
Create a Data Element of Type URL Parameter. For Parameter Name, put e.g. "Role" (no quotes) for prop28. Alternatively, you can do the same thing below, for multiple.
For variables that look for multiple URL parameters:
Create a Data Element of Type Custom Script. Click the [Open Editor] button and in the code box, add the following:
var d=':',
p=['cid','pid','eid'],
v=[],c,l,q;
for (c=0,l=p.length;c<l;c++) {
q=_satellite.getQueryParamCaseInsensitive(p[c]);
if (q) v.push(q);
}
return v.join(d);
The d= and p= values are based on what you have for eVar8. This isn't 100% the same as AA's s.getQueryParam plugin but it's most of it; the parts you care about based on your posted code.
Reference the Data Element(s)
In the Adobe Analytics tool config, in the Global Variables section, you can add your prop(s) and eVar(s) there, using %data_element_name_here% syntax.

Servlet stripping parameter values because of # character

My URL is http://175.24.2.166/download?a=TOP#0;ONE=1;TWO2.
How should I encode the parameter so that when I print the parameter in the Servlet, I get the value in its entirety? Currently when I print the value by using request.getParameter("a") I get the output as TOP instead of TOP#0;ONE=1;TWO2.
You should encode it like this http://175.24.2.166/download?a=TOP%230%3BONE%3D1%3BTWO2 . There are a lot of the encoders in Java, you can try to use URLEncoder or some online encoders for experements
This is known as the "fragment identifier".
as mentioned in wiki
The fragment identifier introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.
the part after the # is info for the client. Put everything your client needs here.
you need to encode your query string.
you can use encodeURIComponent() function in JavaScript encodes a URI component.This function encodes special characters.

String Functions in IIS Url Rewrite Module

The IIS URL Rewrite Module ships with 3 built-in functions:
* ToLower - returns the input string converted to lower case.
* UrlEncode - returns the input string converted to URL-encoded format. This function can be used if the substitution URL in rewrite rule contains special characters (for example non-ASCII or URI-unsafe characters).
* UrlDecode - decodes the URL-encoded input string. This function can be used to decode a condition input before matching it against a pattern.
The functions can be invoked by using the following syntax:
{function_name:any_string}
The question is: can this list be extended by introducing a Replace function that's available for changing values within a rewrite rule action or condition?
Another way to frame the question: is there any way to do a global replace on a URL coming in using this module?
It seems that you're limited to using regular expressions and back-references to construct strings - i.e. there's no search/replace mechanism to replace every instance of X with Y in {REQUEST_URI}, without knowing how many instances there are.
I've had a quick glance at the extensibility introduced in the 2.0 RTW and don't see any 'light' means of introducing this.
Looks like you have to implement your own provider as shown here:
