I'm working on automating an installation for my pi running buster. I want to be able to setup a fresh raspberry pi os installation, and then run some bash scripts to automate the installation of kodi and a couple of plugins. This example shows you how to install the castagnait repository which hosts the plugin.video.netflix. This will only work, if the json-rpc interface for kodi is enabled, of course.

First, you should run the kodi-variables.sh script to set some locations:
 

bash:
variablesScript=$(basename "$0")



kodiHome=~/.kodi

downloadDir=~/Downloads

jsonRpcPort=8080

jsonRpcAddress=localhost



if [ "$variablesScript" == "kodi-variables.sh" ]

then



read -e -i "$kodiHome" -p "Provide kodi home path: " kodiHomeInput

kodiHome=${kodiHomeInput:-$kodiHome}

sed -i -E "s|^(kodiHome=)/.*$|\1$kodiHome|g" "$variablesScript"



read -e -i "$downloadDir" -p "Provide the Downloads directoy location: " downloadDirInput

downloadDir=${downloadDirInput:-$downloadDir}

sed -i -E "s|^(downloadDir=)/.*$|\1$downloadDir|g" "$variablesScript"



read -e -i "$jsonRpcPort" -p "Define the tcp port the jsonRpc server should listen on: " jsonRpcPortInput

jsonRpcPort=${jsonRpcPortInput:-$jsonRpcPort}

sed -i -E "s|^(jsonRpcPort=)[0-9]*$|\1$jsonRpcPort|g" "$variablesScript"



read -e -i "$jsonRpcAddress" -p "Define the address the jsonRpc server will listen on: " jsonRpcAddressInput

jsonRpcAddress=${jsonRpcAddressInput:-$jsonRpcAddress}

sed -i -E "s%^(jsonRpcAddress=).*$%\1$jsonRpcAddress%g" "$variablesScript"



fi

I figured out how to fire post requests without having to wait for a reply. That's done with ncat. For that to work, http requests need to be generated manually, therefore I created a supporting script that helps with that: http-request.sh

bash:
function generateHttpRequest () {

method=$1

endpoint=$2

contentType=$3

targetAddress=$4

targetPort=$5

payload=$6

local result=$(cat <<EOF

$method $endpoint HTTP/1.1

Content-Type: $contentType

Accept: */*

Host: $targetAddress:$targetPort

Connection: close

Content-Length: ${#payload}



$payload

EOF

)

echo "$result"

}

Now, if we want to install plugins or repositories from unknown sources, we'll first need to enable that option. That's what this script does (call it what you want):

bash:
source kodi-variables.sh

source http-request.sh



dpkg -s ncat &> /dev/null

ncatInstalled=$?

if [ $ncatInstalled -ne 0 ]

then

sudo apt -yq install ncat

fi



unknownSourcesJson='{"jsonrpc":"2.0","id":1,"method": "Settings.SetSettingValue", "params": {"setting": "addons.unknownsources", "value": true}}'

enableUnknownSourcesRequest=$(generateHttpRequest "POST" "/jsonrpc" "application/json" "$jsonRpcAddress" "$jsonRpcPort" "$unknownSourcesJson")

echo "$enableUnknownSourcesRequest" | ncat "$jsonRpcAddress" "$jsonRpcPort" --send-only



leftJson='{"jsonrpc":"2.0","id":1,"method": "Input.ExecuteAction", "params": {"action": "left"}}'

leftRequest=$(generateHttpRequest "POST" "/jsonrpc" "application/json" "$jsonRpcAddress" "$jsonRpcPort" "$leftJson")

echo "$leftRequest" | ncat "$jsonRpcAddress" "$jsonRpcPort" --send-only



selectJson='{"jsonrpc":"2.0","id":1,"method": "Input.ExecuteAction", "params": {"action": "select"}}'

selectRequest=$(generateHttpRequest "POST" "/jsonrpc" "application/json" "$jsonRpcAddress" "$jsonRpcPort" "$selectJson")

echo "$selectRequest" | ncat "$jsonRpcAddress" "$jsonRpcPort" --send-only



if [ $ncatInstalled -ne 0 ]

then

sudo apt -yq purge ncat

fi

Lastly you can install the repository with this script:

bash:
source kodi-variables.sh

source http-request.sh



dpkg -s ncat &> /dev/null

ncatInstalled=$?

if [ $ncatInstalled -ne 0 ]

then

sudo apt -yq install ncat

fi



dpkg -s jq &> /dev/null

jqInstalled=$?

if [ $jqInstalled -ne 0 ]

then

sudo apt -yq install jq

fi



getVersionPropertyJson='{"jsonrpc":"2.0","id":1,"method": "Application.GetProperties", "params": {"properties":["version"]}}'

majorVersion=$(curl --silent -X POST -H 'Content-Type: application/json' http://"$jsonRpcAddress":"$jsonRpcPort"/jsonrpc --data "$getVersionPropertyJson" | jq ".result.version.major")



if [ ! -d "$downloadDir" ]

then

echo "$downloadDir does not exist" && exit

fi



if [ $majorVersion -eq 18 ]

then

if [ ! -f $downloadDir/repository.castagnait-1.0.1.zip ]

then

castagnaitRpositoryFileName=repository.castagnait-1.0.1.zip

wget https://github.com/castagnait/repository...-1.0.1.zip -P "$downloadDir"

fi

elif [ $majorVersion -eq 19 ]

then

if [ ! -f $downloadDir/repository.castagnait-1.0.0.zip ]

then

castagnaitRpositoryFileName=repository.castagnait-1.0.0.zip

wget https://github.com/castagnait/repository...-1.0.0.zip -P "$downloadDir"

fi

else

echo "Could not determine kodi version, check if jsonrpc interface is active." && exit

fi

I'd be very happy if you provided some feedback.

I uploaded the scripts to the paste site too, somehow identation got removed in the forum editor:
kodi-variables.sh
http-request.sh
enable-unknown-sources.sh
install-castagnait-repo.sh
