Jmeter authentication token

OAUTH2.0 Authentication token

Authorization with dynamic access token is used to pass the dynamic response content to the subsequent requests which can be further used in APIs to validate the authenticity. It is useful when we want to test our APIs with dynamic access-token authorization rule or if an application uses this access token in multiple authorization request s. To solve the above problem, we will use JMeter basic knowledge of JMeter is required. See the below screenshot:.

We will use it to fetch dynamic access token from the response of Login Request. See the below screenshot. You can read more about JMeter regular expressions here.

It requires access token in the authorization request. Generally, for applications, it includes all the header requests which should be passed with the HTTP Request. Refer to the below screenshot. Refer to point 2. It is being used here in the get call. See the following screenshot. Verify result for the Login Request. See attached screenshot. Verify result for the Dashboard Request. This approach makes it very simple to test APIs in which we need to get authentication token from the server and then passing it on all other requests.

I am trying to imply the basic authentication process for a web service using JMeter. But everytime it throws out an error Unauthorized. Still it does not work. Still no luck. Can someone help. I've found through debugging requests coming in from JMeter that the HTTP Authorization Manager module doesn't encode the username and password correctly.

It puts a newline character after the username. Basically to bypass a Basic Authorization you need to add the Authorization header with the value Basic base64 username:password. The problem is that JMeter has no base64 function embedded. So in the end when you create a http request Authorization header will be passed to the server with base64 encoded string. If you're looking to learn JMeter, this book by 3 developers of the project will help you.

Make sure to provide a protocol for the base URL, i. In reference to the first answer above, the incorrect encoding problem you mention must be now fixed, as Apache 3. Verified on current host amazon linux having reverse proxy from apache 2.

It worked for me, although, my only complaint is you need to dumb down your answer for guys like myself ; I didn't initially understand what you were telling us to do but luckily thru trial and error and re-reading your answer, somehow stumbled to the correct commands.

I use Postman for my initial testing. It's nice to know there's a website out there that will do the encoding for you though! Works for me too. Depy, pls mark this answer as solution.Rest APIs are increasingly popular these days. They are also frequently being used in Microservices. To perform this authentication, before sending the request, we have to send a prior login request with the right credentials.

It will give us the token and we will pass it in the subsequent request. Before starting configuration, add the View Result Tree Listener. This will help to us with which token we should extract. Our example is getting the active SIM number from the web service. This is because our Rest API needs to be authorized. We understand from this error message that we have to successfully log in to the system first. The system will give the us authorization token that we need to extract and pass into the next request.

And we will add to this sampler to the Thread Group. So we need to set a Content-Type header. We selected it because our required token resides in it as we saw above.

All of the configuration is done! After checking that your script worked well, you can run this script, as you would with any JMeter script, on AWS Amazon Web Services to perform load test.

Apache JMeter is one of the most popular tools for load testing and scaling out your JMeter test plan on the cloud in RedLine13 is easy. This guide and video walks you through running your first JMeter test. Skip to content. Next Post: What is Load Testing?Unless you're load testing static sites or blogs, you're probably going to need to get through some sort of an authentication barrier to be able to test your server's performance.

In this article we're going to set up a quick prototype for handling Token-based authentication with our favorite load testing tool - JMeter. The Thread Group can stay with it's default values, we don't really care about it at this point - all that really matters is that we got something to execute.

We're going to need a results three so we can check if the requests succeeded or failed. You'll be able to see the check the test output, as well as details from each Request here.

We're going to add a JSON extractor to the Authentication Request we created earlier, so that we can extract the token value and store it in a global variable. We're using the simple controller to logically group every request that needs the authentication token and apply it to them via the HTTP Header Manager.

We're using the HTTP Header Manager to add the authentication token to the header of every request grouped inside the Simple Controller we created above. Now the token returned should be stored in a global variable called token. That's it. Have fun! Andrei Gaspar. Share this.Basic Access Authentication is one of the most simple authentication method :. HTTPBin is a demo application of great use: it provides sample endpoints to call with configurable parameters. Chrome Basic Authentication Prompt.

The default username is user and the default password is passwd. The server should respond with the following json:. Chrome Authentication Failure. There is no Authorization header within the request. Chrome Authentication Success. The Authorization Manager lets you specify one or more user logins for web pages that are restricted using server authentication. It provides the ability to automatically add the relevant Authorization http header to subsequent http requests.

Add the following line to the table:. The screen above shows the final configuration once done properly. HTTP Request to the basic authenticated endpoint. All other settings can be left as is.

Test Rest APIs with Authentication Using JMeter

Http Authorization manager is disabled. Http Authorization manager is enabled. A closer inspection of the request headers shows:. What about Digest Authentication?

Web application Multiple user Login Logout Load Test, using JMeter

The authorization manager works great for Basic and Kerberos authentication thought. The Www-Authenticate header must therefore be generated manually using a script.

You need to add the Authorization header with the value Basic base64Encode username:password. The problem is that JMeter has no base64 function. JSR PreProcessor with the script. HTTP Header manager after the preprocessor. Request authenticates successfully.

The script encoded the username and password combinations into a Base64 string, then put it in a variable. Finally, we reuse that variable within the header manager. This is the third and last method to configure Basic Authentication: using the base64Encode function from Custom Functions Plugin. Installing Custom Functions plugin. Open the Plugins Manager, then select Available Plugins and type function.

The Custom JMeter Functions plugin should show up. Click on Apply changes and restart JMeter to install it. This is why we installed the plugin: as seen previously, JMeter has no base64 function by default. It create a new HTTPClient and configures it properly to include the digest authentication header which should look like:.Search everywhere only in this topic. Advanced Search.

Classic List Threaded. Ramkumar Selvaraj. Hi All, I have a requirement to test performance for Rest web Api by creating a customer registration page. Before creating a customer page, it requires to get the access token from the registered system called Azure Active directory AD Tenant system where the system is deployed.

I am not sure how to do this,anybody can share some ideas or steps how to proceed this through JMeter. Please give me some inputs how to do this through JMeter. Its an urgent requirement. Thanks for the support Cheers, Ram. This post has NOT been accepted by the mailing list yet. In reply to this post by Ramkumar Selvaraj. The way I learned was watching YouTube videos. I don't know OAuth specifically, but maybe I can steer you in the right direction. You send your credentials to the authority It responds with "keys", kind of like session IDs You want to Add - Post Processors - Regular Expression Extractor You designate where to look body, response header, etc Reference Name is your variable name, which will be populated Regular Expression is what to look for creating that is part art, part science Template: I don't remember what this is.

Match No you can leave blank for "grab the first hit" Default Value: Put whatever you want the variable filled with when no hit is found. You may need to grab multiple pieces of data so you can send those back in subsequent calls. It's really useful to record once so you can look at the result tree and study what pieces of data are going back and forth.

Hi Ram, You can use Webdriver sampler to do the login process and capture the token from the cookies or headers. In reply to this post by derek kelly.No theory here, only practice : everything is based on a realistic Rest API not a dummy example.

You can download the sample JMX while following the tutorial. But how does the authentication works?

jmeter authentication token

How can we simulate a login with JMeter? Most Rest APIs work with the following login workflow :. See the token here? Here we have our Login Http Request ready to be sent to our servers.

Login request sent to the server. As we can see, the sent request is a POST form-urlencoded which contains our login and passwords. Nothing difficult here! Response received from the server. Token Based Authentication is a simple mechanism where a token uniquely identifies a user session. We need to handle this dynamic parameter to properly simulate a user interacting with our Json API.

The process of extracting a variable from a response works as follows:. Extracting Authentication Token from server response. See where I placed the extractor? Right under the login HTTP request. Enabling JMeter variables in Debug Sampler. By setting JMeter Variables to truewe enable the sampler to output the variables during the test run.

Token is successfully extracted from server response using Json Extractor. The Json extractor is perfectly working. It extracts the value of the token field from the Json response. Our Rest API has many endpoints which require authentication. Those endpoints provide data like user workspaces, projects, virtual users and more. To access user-protected endpoints, one must:.

It should return a Json response containing the user workspaces.
