The old Makefiles which can be used to build this samples directly as Linux apps and the description in the READMEs could be quite missleading. Building this apps in this way has nothing to do with the Zephyr native_posix/sim targets. This is about building them as actual Linux applications without Zephyr or any HW models. So let's rename the Makefiles and change the description in the docs to avoid confusion. Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no>

:name: Dumb HTTP server
|
|
:relevant-api: bsd_sockets net_pkt
|
|
|
|
Implement a simple, portable, HTTP server using BSD sockets.
|
|
|
|
Overview
|
|
********
|
|
|
|
The sockets/dumb_http_server sample application for Zephyr implements a
|
|
skeleton HTTP server using a BSD Sockets compatible API. The purpose of
|
|
this sample is to show how it's possible to develop a sockets application
|
|
portable to both POSIX and Zephyr. As such, this HTTP server example is
|
|
kept very minimal and does not really parse an incoming HTTP request,
|
|
just reads and discards it, and always serve a single static page. Even
|
|
with such simplification, it is useful as an example of a socket
|
|
application which can be accessed via a conventional web browser, or to
|
|
perform performance/regression testing using existing HTTP diagnostic
|
|
tools.
|
|
|
|
The source code for this sample application can be found at:
|
|
:zephyr_file:`samples/net/sockets/dumb_http_server`.

Requirements
|
|
************
|
|
|
|
- :ref:`networking_with_host`
|
|
- or, a board with hardware networking
|
|
|
|
Building and Running
|
|
********************
|
|
|
|
Build the Zephyr version of the sockets/echo application like this:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/net/sockets/dumb_http_server
|
|
:board: <board_to_use>
|
|
:goals: build
|
|
:compact:
|
|
|
|
After the sample starts, it expects connections at 192.0.2.1, port 8080.
|
|
The easiest way to connect is by opening a following URL in a web
|
|
browser: http://192.0.2.1:8080/ . You should see a page with a sample
|
|
content about Zephyr (captured at a particular time from Zephyr's web
|
|
site, note that it may differ from the content on the live Zephyr site).
|
|
Alternatively, a tool like ``curl`` can be used:
|
|
|
|
.. code-block:: console
|
|
|
|
$ curl http://192.0.2.1:8080/
|
|
|
|
Finally, you can run an HTTP profiling/load tool like Apache Bench
|
|
(``ab``) against the server::
|
|
|
|
$ ab -n10 http://192.0.2.1:8080/
|
|
|
|
``-n`` parameter specifies the number of HTTP requests to issue against
|
|
a server.
|
|
|
|
Running application on POSIX Host
|
|
=================================
|
|
|
|
The same application source code can be built for a POSIX system, e.g.
|
|
Linux. (Note: if you look at the source, you will see that the code is
|
|
the same except the header files are different for Zephyr vs POSIX.)
|
|
|
|
To build:
|
|
|
|
.. code-block:: console
|
|
|
|
$ make -f Makefile.host
|
|
|
|
To run:
|
|
|
|
.. code-block:: console
|
|
|
|
$ ./socket_dumb_http
|
|
|
|
To test, connect to http://127.0.0.1:8080/ , and follow the steps in the
|
|
previous section.
|
|
|
|
As can be seen, the behavior of the application is the same as the Zephyr
|
|
version.
