I am using JMeter with an authenticated proxy e.g.
jmeter -H 10.12.12.5 -P 1080 -u myuser -a password
In Fiddler I've done a Rules->Customize as below where xxxxxxxxxx is the base64 encoding of my username:password:
if (!oSession.isHTTPS)
{
oSession.oRequest["Proxy-Authorization"] = "Basic xxxxxxxxxx";
}
Also under Tools->Options-Gateway I've set Manual Proxy and entered the proxies as:
http=10.12.12.5;https=10.12.12.5
However when I playback the traffic from JMeter Fiddler is not picking it up.
Man, you pointed both JMeter and Fiddler to use some 3rd-party proxy, there is no any connectivity between them, if you want to see JMeter's traffic in Fiddler - you need to:
Configure Fiddler to use the 3rd-party proxy
Configure JMeter to use Fiddler as the proxy something like:
In Fiddler Tools->Options-Gateway http=10.12.12.5;https=10.12.12.5
In Fiddler Tools-> Options - Connections - Fiddler listens on port - check the value, the default is 8888
Run JMeter to use Fiddler as the proxy like:
jmeter -H localhost -P 8888
You might need to import Fiddler's certificate into JMeter or vice versa
And last but not the least, you can use JMeter's HTTP Header Manager to send this Proxy-Authorization header

I am running a Groovy script to capture traffic over proxy port in OWASP ZAP.
For https site, I am setting the proxy as given below and I can see the traffic in ZAP when I run my script.
System.setProperty('https.proxyPort', '8083')
System.setProperty('https.proxyHost', '127.0.0.1')
For http site, I am setting the proxy as given below but I can not see the traffic.
System.setProperty('http.proxyPort', '8083')
System.setProperty('http.proxyHost', '127.0.0.1')
The same settings although work fine when configured on Chrome. I have tried using the IP address instead of 127.0.0.1 but that also did not help. What could be going on wrong here ?
i have a windows 10 computer and a program, that sends to a server (xxx.com aka x.x.x.x) a request. server responses with, for example, "false". that program reads that response and based on that gives output. I need to locally (not on the server, only for me) change that value for, for example, "true". I tried Charles, but it doesn't work for my soft (in browser same requests that go through Charles give "true"). What is the problem here?
Charles "doesn't work" for your program because the HTTP request sent from your program is not intercepted. Charles can autoconfigure the proxy setting for browsers, that's why in your browser "same requests that go through Charles give true".
In order to make Charles intercept your program's HTTP request, a reverse proxy need to be configured:
Step 1. Launch Charles, and go to Proxy - Reverse Proxies...
Step 2. Check Enable Reverse Proxies and click Add.
Step 3. Configure a reverse proxy:
Local port: 59110 // any unused local port
Remote host: xxx.com // the target server
Remote port: 80 // the port opened in target server
Step 4. In your program, send all HTTP requests to localhost:59110.
In this way, Charles can intercept all HTTP requests sent from your program, and you can change the HTTP response data.
If the target server provides HTTPS service instead of HTTP, some additional work need to be done:
SSL-Step 1. In Charles, go to Proxy - SSL Proxying Settings - SSL Proxying
SSL-Step 2. Check Enable SSL Proxying and click Add:
SSL-Step 3. Configure an SSL proxy:
Host: xxx.com // the target server
Port: 443 // the SSL port opened in target server
SSL-Step 4 (1). go to Help - SSL Proxying - Install Charles Root Certificate. This will allow your program trust the self-generated certificate from Charles.
or
SSL-Step (2). If you don't want to install Charles' root CA, you can change your program to prevent certificate error. For example, in Node.js, the following code can prevent program from rejecting unauthorized certificate:
process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
I had follow all the below given Steps.
Please check and suggest me solution for this.
1.Create Thread Group.
2.HTTP Request(with Port 8080 and IP/Server Name as localhost.
3.HTTP Request Defaults(with Port 8080 and IP/Server Name as localhost).
4.Added Recording Controller.
5.Under Workbench created HTTP(s) Test Script Recorder
6.Updated URL patterns (.*.html).
7.Added View Result Tree.
8.Clicked on Start and install Root CA certificate(Click OK).
9.Set a Proxy in Firefox.
10.Firefox Option Advanced Network Setting.
Check the Manual Proxy Configuration.
HTTP Proxy: localhost and Port: 8080.
11.Check the "Use this Proxy Server for all Protocol".
No Proxy for "localhost".
Finally I have did not see any script that has been recorded.
You Can Follow these below steps:
Open Jmeter.
Click on Templates... (File->Templates... )
Just Click on "Create" button.
Then open up your Firefox browser.
Then Open Menu-> Options -> Advanced -> Network -> Connection Settings.
Then configure just like this.
Then just click OK.
Start the HTTP(s) Test Script Recorder from Jmeter.
9.Now Install Root CA certificate.
Restart your Firefox and you are just ready to record your test script.
You will find your recorded script under the "Recording Controller" section!!
Hope, this will help you. :)
It might be the case you're trying to record secure (HTTPS) traffic.
Make sure "Use this proxy server for all protocols" box is checked
Make sure "No Proxy for" box is empty
You can also consider an alternative recording approach - JMeter Chrome Extension - in that case you won't have to worry about proxies, SSL certificates, browser configuration, etc. - click one single button and you're all set.
- In step #2, You don't need to specify anything in HTTP Requests, HTTP requests will
be added automatically when you record your script successfully.
- In step #3, DO NOT use server name as "Localhost" and port number as JMeter's port.
Only when you want to test HTTPS domains, you specify HTTPS as a protocol.
Also, if you are testing an application that requires a specific port number (Example:
htts://somedomain.com:9595/somepath/) you specify the Server/IP Name and the PORT in the
HTTPS Default.
- In step #5, you specify JMeter port number (8080 or 8888 or...), and chose "Target
Controller" to "Use Recording Controller". You will find recorded script in Recording
Controller when you expand it after recording is done.
- In step #10, use the same port number you specified in step #5.
For me, the solution was to create an alias for 127.0.0.1 in /etc/hosts:
127.0.0.1 myserver
and create the JMeter script from the Recording template as detailed at https://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.html, specifying "myserver" as the host (instead of www.example.com).
Also, if your backend listens on a specific port, you have to specify that port in the "HTTP Request Defaults", under "Port Number".
My web application doesn't uses browser. It is a MS Word plugin and uses port 80.
When I try to record on port 80, Jmeter says 'port already in use'
And if i set other port in my app, app doesn't work properly.
What to do in this case??
Thanks
If your MS Word Plugin has proxy settings - configure it to use JMeter's Proxy.
If it doesn't have its own proxy settings - it should respect system proxy configuration (usually it can be configured via Internet Explorer proxy settings)
You can use 3rd-party tool like Wireshark or Fiddler to capture the traffic and convert it to JMeter .jmx script.
The only way you can do it as I see it is not through script recording but by setting requests in jMeter manually and build whole test plan like this. It's not so hard anyway if you know how your plugin works and requests you send. Some short info can be find here:
http://jmeter.apache.org/usermanual/build-web-test-plan.html
Error message 'port already in use' means that port 80 was assinged to some other service. You can't assign that port to Jmeter proxy server to start. (Jmeter has to start its own service on some unused port)
a. Just start Jmeter on its default port 8080 (or some other unused port).
b. Redirect required traffic to Jmeter proxy port (i.e, 8080). MS office will honor System proxy settings, so change the IE proxy setting to server '127.0.0.1' port '8080', it should automatically apply to office.
c. Now all the HTTP requests trigger from Office should visible in Jmeter Proxy recorder. After that you can move them to required location in Test Plan.
As Dmitri Said, you can also use Fiddler to track the requests (Prefer Fiddler over Wireshark, for its ease of use).
Good Luck!
I created a JMeter recording. But when I start the Test,
I don't see any request going in Fiddler. I changed the
port number in Fiddler to 8080, that I am using in JMeter.
Steps:
Create a Thread Group
Add Http Request to the Thread Group and enter URL
Add Recording Controller to the Thread Group
Add HTTP(S) Test Script Recorder
Change Firefox settings to localhost proxy and 8080 port
Record Test
Then start Fiddler and start the test
I am not sure whether JMeter is really running the test successfully.
However it is showing the number of users as 10 and no errors when I
run the test. Is there anything that I am missing?
First, change Fiddler's port back to 8888 as it was originally.
Next, change JMeter's proxy settings to point at 127.0.0.1 on port 8888 as its proxy settings.
Then, run your test.
To record traffic from JMeter via Fiddler use the next setup
Importent
I used JMeter 5.0
Recheck that your Fiddler listing port set to 8888
UI Mode
Create Thread Group --> HTTP Request
Go to Advanced fill "Server Name or IP:" = 127.0.0.1 , "Port Number:" = 8888
Non UI MODE
Add to your command -H 127.0.0.1 for Proxy Host
-P 8888 for Proxy port
Example:
C:\jmeter5.0\bin>jmeter -n -t C:\example.jmx -l C:\scriptresults.jtl -H 127.0.0.1 -P 8888
I would not suggest using fiddler as JMeter has its own recorder now.
To record a series of requests you need to follow the below steps.
Open JMeter
Right-click on 'Test Plan' and navigate to 'Threads (Users)' under 'Add' menu and then choose 'Thread Group'
Now, right-click on 'Thread Group' and navigate to 'Login Controller' under 'Add' menu and then choose 'Recording Controller'
Now right-click on 'Test Plan' again then navigate to 'Non-Test Elements' under 'Add' menu and then click on 'HTTP(S) Test Script Recorder'
Now without making any changes, click on the start button in the right section and then move to your browser.
Now configure your browser to use the proxy
Host: localhost
Port: 8888 (You can change this if you have changed the same in JMeter but make sure both have same values)
Now browse the internet as you normally do.
The above procedure will enable you to record traffic without hassles.
Remember, this will work for websites without HTTPS only.
