# mbed-os-example-http(s) This application demonstrates how to make HTTP and HTTPS requests and parse the response from mbed OS 5. It consists of four demo's, which you can select in ``source/select-demo.h``. * HTTP demo: * Does a GET request to http://httpbin.org/status/418. * Does a POST request to http://httpbin.org/post. * HTTPS demo: * Does a GET request to https://developer.mbed.org/media/uploads/mbed_official/hello.txt. * Does a POST request to https://httpbin.org/post. * HTTP demo with socket re-use. * HTTPS demo with socket re-use. Response parsing is done through [nodejs/http-parser](https://github.com/nodejs/http-parser). **Note:** HTTPS requests do not work on targets with less than 128K of RAM due to the size of the TLS handshake. For more background see [mbed-http](https://developer.mbed.org/teams/sandbox/code/mbed-http). ## To build 1. Open ``mbed_app.json`` and change the `network-interface` option to your connectivity method ([more info](https://github.com/ARMmbed/easy-connect)). 2. Build the project in the online compiler or using mbed CLI. 3. Flash the project to your development board. 4. Attach a serial monitor to your board to see the debug messages. ## Entropy (or lack thereof) On all platforms **except** the FRDM-K64F, FRDM-K22F and EVK-ODIN-W2, the application is compiled without TLS entropy sources. This means that your code is inherently unsafe and should not be deployed to any production systems. To enable entropy, remove the `MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES` and `MBEDTLS_TEST_NULL_ENTROPY` macros from mbed_app.json. ## Flash size Default flash size for HTTPS is very large, as the application is loading the default mbed TLS configuration. To use a more optimized version, include `mbedtls_config.h` in your mbed_app.json, by adding: ``` "MBEDTLS_CONFIG_FILE=\"fotalora_mbedtls_config.h\"" ``` to the `macros` array. ## Tested on * K64F with Ethernet. * NUCLEO_F411RE with ESP8266. * ODIN-W2 with WiFi.
