Development Tools HTTP Basics Introduction to HTTP Sending Data with a POST Request

I cannot replicate the 404 error in the video at [4:14] .

When I set the Content-Length to 30 characters — less than is required — I simply get a shortened data string back as a response instead of the 404 error :

Here is the original POST Request in the terminal on my Mac :

POST /post HTTP/1.1
Host: httpbin.org
Content-Length: 30

firstname=Dorothy&language=English

After pressing enter , I get back the following response :

"data": "firstname=Dorothy&language=Eng"

Notice how the original word — English — has been shortened to Eng .

I've just had the same issue here (Windows, using workspaces). I copied the input directly from the tutorial:

 POST /post HTTP/1.1

Like in your case, the query input is just cut down and accepted.

I was getting the same results as you where the characters were getting cut off at 30 bytes. It makes sense, per the content-length that was set, but it's confusing versus watching the video.
