leading slash in Http Request Path variable
Using latest jmeter and java.
Reading urls from a csv file and passing into the Path
for the HTTP Request
Each url in the file is like so:
http://www.example.com/
The default "HTTP Request Defaults" specify the proxy
server that the requests go through. The problem is
that jmeter inserts a leading slash before ${url} and
the proxy just wants a GET http://www.example.com
HTTP/1.1 but jmeter is sending a GET
/http://www.example.com HTTP/1.1
Does anyone know what file to change or setting to set
to fix this? It seems like a bug to me, but maybe
it's just a feature that doesn't make sense to me.

Re: JAVA REQUEST - ${__CSVRead and NEXT VALUE
Posted by sebb <se...@gmail.com>.
That's by design - CSVRead will always start a new line for each new
thread, but will only start a new line within a thread if the thread
uses next.
Otherwise how would JMeter know if the thread had finished reading
columns from the row?

Because you have not used next()
The following should work:
${__CSVRead(try.csv,0)}${__CSVRead(try.csv,next)}
But the CSV Dataset element is much easier to use.

What are you trying to achieve?
I don't understand what the counter has got to do with CSVRead.

As far as I know, proxies need different handling from servers, but I
suppose it might work for some simple cases.

Darn. At least it's on the radar. I'm seeing proxies
more often now for different reasons and different
uses. Having the Proxy GUI setup as an option would
be a big plus from my perspective.
Actually if only that leading slash weren't prepended
I think I could make it work. So if the HTTP Request
Path variable was used as-is and a "/" wasn't
prepended I think I could go on my merry way. I'll
poke around in the source for that.
Thank you.

JAVA REQUEST - ${__CSVRead and NEXT VALUE
Posted by Fulvio Guglielmelli <fu...@yahoo.it>.
Hi,
i have a JAVA REQUEST class with parameter
a | ${__CSVRead(try.csv,0)}
whei i run the test, into the java class it always read the first ROW of try.csv file.
Into the log i saw jmeter read the next value i don't know how take it to be use.
I tried to use
a | ${__CSVRead(try.csv,next)}
a | ${__CSVRead(try.csv,next())}
or into the java class class
params.addArgument("a", "${__CSVRead(try.csv.csv,next())}");
but Jmeter return null value
I can make in way
1) Using a loop Controller
2) Using a ${__counter(,)}
My problem is: HOW CAN I PASS THE counter VALUE TO THE JAVA CLASS and use it in CSVRead?
Could you help me?
FULVIO

That is definitely not possible with standard Java Http, because the
proxy is defined using system properties - and that cannot be done
independently per thread.
It would be possible with the HttpClient implementation, but has not
been implemented. As far as I know, this is the first time that this
scenario has arisen.
We are considering implementing Proxy setup via a GUI item. This would
probably solve your problem. But at present it's not possible.

We want to mimic multiple users and each user has to
authenticate with the proxy. I'll use an example again
since I don't do a great job explaining all this. If I
use wget I specify the proxy_user and proxy_passwd for
a request. The proxy authenticates by taking the
user+pass and base64 encoding and then doing the Basic
auth. So as a workaround, that will enable us to use
Jmeter for this, we'd run Jmeter with a
proxy/port/user/pass on the command line. That starts
the test using our test plan but only authenticates
once against the proxy and that does NOT mimic the
production reality. Hope I'm making sense, really
appreciate the help.

One normally only uses at most one Proxy.
I don't understand what you are trying to do.

Wow, may well prevent using jmeter. What if we need
to specify 100,000 users for the proxy?
Is there a better way than to have to specify 100,000
jmeter command lines to test 100,000 users? I guess
we could auth for one user but that's not reflective
of reality in this case.

I probably did not explain this well, and although
what you say is probably true and correct it doesn't
apply in this case.
Maybe an example will help. If I use wget
wget -e http_proxy=proxy.example.com
http://www.example.com
Then everything works just fine the proxy host
(proxy.example.com here) shows it receives a
GET http://www.example.com HTTP/1.1
But if I use jmeter the proxy.example.com always gets
a
GET /http://www.example.com HTTP/1.1
Here's the setup:
1. HTTP Request Default has proxy.example.com as the
server variable
2. HTTP Request has ${url} for the Path variable
But jmeter, incorrectly I believe, inserts a leading
slash. Anyway I really just need to know where that
happens so I can modify the java that's doing that.
Do you happen to know?
proxy.example.com is a transparent proxy only.
