How send application/x-www-form-urlencoded params

Question

I developed a rest server, and I put it to run in localhost, and I'm trying to perform tests with JMeter, sending requests posts and gets (depends of called method).

I already send to Rest server and got result with JMeter in simple post requests, get requests, sending files with post, and sending a Json with post.

But I don't know how to send a Form-UrlEncoded object to server. My Rest server consumes application/x-www-form-urlencoded, and I need to send 3 String parameters.

There's some way to set the MimeType for every parameter and perform the test ?

I'm using Jmeter 2.7

• [Update]

I solved this by disabling the option:

use multipart/form-data for post

And enabling:

redirect automatically

Instead of:

follow redirect

The parameters I put normally in the table "Send parameters with the Request" with each respective names.

Answer 1

Have you tried to save your test using BadBoy or JMeter Proxy to see what your application actually sends?

To see what happens under the hood you can also use FireBug if you're using FireFox or Ctrl+Shift+i if you're on Chrome.

Answer 2

For sending form parameters as application/x-www-form-urlencoded, add a header parameter Content-Type with value application/x-www-form-urlencoded.

The following steps is aplicable for Jmeter 2.3.4

1. Add a HTTP Header Manager under your http Request.
2. Add new parameter to HTTP Header Manager with name Content-Type and value application/x-www-form-urlencoded.
3. Uncheck "Use multipart/form-data for HTTP POST" of HTTP request.
4. Uncheck "Encode?" of each request parameter(not necessary).

5. kept "Content Encode:" text box of HTTP request as empty.

   This won't work for PUT request. For put request add parameters as path parameter and set Content-Type header then Jmeter will do by itself.

Answer 4

IllegalCharsetNameException will go immediately only after you will add the required content-type in HTTP Header Manager for HTTP request .

Hope this helps.

Answer 5

Here's the solution for HTTP POST with x-www-form-urlencoded testing with jmeter. You just folllow like these.

Go to Thread Group -> Add listener -> Views Result in table, View result Tree. To see the process of responding.
