# Helloworld Service
A binding example for AGL
## Pre-requisites
Please follow [this guide](https://docs.automotivelinux.org/en/master/#3_Developer_Guides/2_Application_Framework_Binder/2_How_to_write_a_binding/)
to add the AGL-Master repository to your distribution.\
In order to load these files into the current shell script, use the following command :
* **Debian/Ubuntu**
```bash
source /etc/profile.d/agl-app-framework-binder.sh
```
### CMake module
Then install the cmake module using your distribution package manager.
* **Debian/Ubuntu**
```bash
sudo apt-get install agl-cmake-apps-module-bin
```
* **openSUSE**
```bash
sudo zypper install agl-cmake-apps-module
```
* **Fedora**
```bash
sudo dnf install agl-cmake-apps-module
```
### Build dependency
Because the helloworld-service binding uses json, the following package has to be installed.
* **Debian/Ubuntu**
```bash
sudo apt-get install libjson-c-dev agl-libafb-helpers-dev
```
* **openSUSE**
```bash
sudo zypper install libjson-c-devel agl-libafb-helpers-devel
```
* **Fedora**
```bash
sudo dnf install libjson-c-devel
```
## Setup
```bash
git clone https://gerrit.automotivelinux.org/gerrit/apps/agl-service-helloworld
cd agl-service-helloworld
```
## Build for AGL
```bash
#setup your build environnement
. /xdt/sdk/environment-setup-aarch64-agl-linux
#build your application
./autobuild/agl/autobuild package
```
## Build for 'native' Linux distribution (Fedora, openSUSE, Debian, Ubuntu, ...)
```bash
./autobuild/linux/autobuild package
```
## Deploy
### Deploy on AGL
```bash
export YOUR_BOARD_IP=192.168.1.X
export APP_NAME=agl-service-helloworld
scp build/${APP_NAME}.wgt root@${YOUR_BOARD_IP}:/tmp
ssh root@${YOUR_BOARD_IP} afm-util install /tmp/${APP_NAME}.wgt
APP_VERSION=$(ssh root@${YOUR_BOARD_IP} afm-util list | grep ${APP_NAME}@ | cut -d"\"" -f4| cut -d"@" -f2)
ssh root@${YOUR_BOARD_IP} afm-util start ${APP_NAME}@${APP_VERSION}
```
## TEST
### TEST on AGL
```bash
export YOUR_BOARD_IP=192.168.1.X
export PORT=8000
ssh root@${YOUR_BOARD_IP} afb-daemon --ws-client=unix:/run/platform/apis/ws/helloworld --port=${PORT} --token='x' -v
#On an other terminal
ssh root@${YOUR_BOARD_IP} afb-client-demo -H 127.0.0.1:${PORT}/api?token=x helloworld ping true
#or
curl http://${YOUR_BOARD_IP}:${PORT}/api/helloworld/ping?token=x
#For a nice display
curl http://${YOUR_BOARD_IP}:${PORT}/api/helloworld/ping?token=x 2>/dev/null | python -m json.tool
```
### Native Linux
For native build you need to have tools **afb-daemon**.
You can build it by yourself [app-framework-binder][app-framework-binder], or use binary package from OBS:[https://en.opensuse.org/LinuxAutomotive](https://en.opensuse.org/LinuxAutomotive)
```bash
export PORT=1234
cd build
afb-daemon --port=${PORT} --ldpaths=package --workdir=. --roothttp=../htdocs --token= --verbose
xdg-open http://localhost:${PORT}/
#Command line test
curl http://localhost:${PORT}/api/helloworld/ping
#For a nice display
curl http://localhost:${PORT}/api/helloworld/ping 2>/dev/null | python -m json.tool
```
## Activate authentication security
To test auth just switch the line:
```diff
static const struct afb_verb_v2 verbs[]= {
/*Without security*/
- { .verb = "ping" , .session = AFB_SESSION_NONE, .callback = pingSample , .auth = NULL},
+ /*{ .verb = "ping" , .session = AFB_SESSION_NONE, .callback = pingSample , .auth = NULL},*/
/*With security "urn:AGL:permission:monitor:public:get"*/
- /*{ .verb = "ping" , .session = AFB_SESSION_NONE, .callback = pingSample , .auth = &_afb_auths_v2_monitor[1]},*/
+ { .verb = "ping" , .session = AFB_SESSION_NONE, .callback = pingSample , .auth = &_afb_auths_v2_monitor[1]},
{NULL}
};
```
And rebuild your application
