This section provides an introduction on how to use Swagger to generate an API client.
API Specifications
The index.json of each micro-service contains its respective LMC API specification. The location of each index.json is https://cloud.lancom.de/<micro-service>/api-docs/index.json.
One way of downloading all of these files is:
#!/bin/bash
BASEURL=https://cloud.lancom.de # change this if you are using a private LMC
if [ ! -d api-spec ];
then
mkdir api-spec
fi
for i in auth backstage config control devices devicetunnel dsc \
fields geolocation jobs logging messaging monitoring notification \
preferences; # add missing services here
do
wget $BASEURL/cloud-service-$i/api-docs/index.json -O api-spec/$i.json
done
Swagger Code Generator
Swagger provides a Java JAR to generate code from a given API specification (index-json).
You can download the latest release from here: https://github.com/swagger-api/swagger-codegen/releases
Java Client
The following bash script generates a java client.
#!/bin/bash
# usage:
# command <index.json> <output-dir>
java -Dapis -Dmodels -DsupportingFiles -Dmodels -jar swagger-codegen-cli.jar \
generate -l java \
--library resttemplate \
--additional-properties java8=true \
--api-package de.lcs.lmc.api \
--model-package de.lcs.lmc.dto \
--group-id de.lcs.lmc \
--artifact-id de.lcs.lmc.$(basename $1 .json) \
--artifact-version v1.0 \
-DdateLibrary=other \
-i $1 -o "$2/"
