This sample application implements an HTTP(S) client that will do an HTTP or HTTPS request and wait for the response from the HTTP server.
The source code for this sample application can be found at: :zephyr_file:`samples/net/sockets/http_client`.
networking_with_host
You can use this application on a supported board, including running it inside QEMU as described in networking_with_qemu
.
Build the http-client sample application like this:
Enable TLS support in the sample by building the project with the overlay-tls.conf
overlay file enabled using these commands:
An alternative way is to specify -DOVERLAY_CONFIG=overlay-tls.conf
when running west build
or cmake
.
The certificate and private key used by the sample can be found in the sample's :zephyr_file:`samples/net/sockets/http_client/src/ directory. The default certificates used by Socket HTTP Client and https-server.py program found in the `net-tools <https://github.com/zephyrproject-rtos/net-tools>_ project, enable establishing a secure connection between the samples.
You can run this http-client
sample application in QEMU and run the http-server.py
(from net-tools) on a Linux host.
To use QEMU for testing, follow the networking_with_qemu
guide.
In a terminal window:
$ ./http-server.py
Run http-client
application in QEMU:
Note that http-server.py
must be running in the Linux host terminal window before you start the http-client application in QEMU. Exit QEMU by pressing CTRL+A
x
.
You can verify TLS communication with a Linux host as well. Just use the https-server.py
program in net-tools project.
