iobroker.rest-api

REST-API adapter

This adapter uses Sentry libraries to automatically report exceptions and code errors to the developers. For more details and for information how to disable the error reporting see Sentry-Plugin Documentation! Sentry reporting is used starting with js-controller 3.0.

This is a RESTFul interface to read the objects and states from ioBroker and to write/control the states over HTTP Get/Post requests.

The purpose of this adapter is similar to simple-api. But this adapter supports long-polling and URL hooks for subscribes.

It has a very useful web interface to play with the requests:

Usage

Call in browser http://ipaddress:8093/ and use Swagger UI to request and modify the states and objects.

Some request examples:

• http://ipaddress:8093/v1/state/system.adapter.rest-api.0.memHeapTotal - read state as JSON
• http://ipaddress:8093/v1/state/system.adapter.rest-api.0.memHeapTotal/plain - read state as string (only value)
• http://ipaddress:8093/v1/state/system.adapter.rest-api.0.memHeapTotal?value=5 - write state with GET (only for back compatibility with simple-api)
• http://ipaddress:8093/v1/sendto/javascript.0?message=toScript&data={"message":"MESSAGE","data":"FROM REST-API"} - send a message to javascript.0 in script scriptName

Subscribe to the state's or object's changes

Your application could get notifications by every change of the state or object.

For that, your application must provide an HTTP(S) end-point to accept the updates.

Example in node.js see here demoNodeClient.js

Long polling

This adapter supports a subscribing on data changes via long polling.

Example for browser could be found here: demoNodeClient.js

Web extension

This adapter can run as a web extension. In this case, the path is available under http://iipaddress:8082/rest

Notice

• POST is always for creating a resource (does not matter if it was duplicated)
• PUT is for checking if resource exists then update, else create new resource
• PATCH is always for updating a resource

Commands

Additionally, you can execute many socket commands via special interface:

http://ipaddress:8093/v1/command/<commandName>?arg1=Value2&arg2=Value2

E.g.

• http://ipaddress:8093/v1/command/getState?id=system.adapter.admin.0.alive - to read the state of system.adapter.admin.0.alive
• http://ipaddress:8093/v1/command/readFile?adapter=admin.admin&fileName=admin.png - to read the file admin.admin/admin.png as JSON result
• http://ipaddress:8093/v1/command/readFile?adapter=admin.admin&fileName=admin.png?binary - to read the file admin.admin/admin.png as file
• http://ipaddress:8093/v1/command/extendObject?id=system.adapter.admin.0?obj={"common":{"enabled":true}} - to restart admin

You can request all commands with POST method too. As body must be an object with parameters. E.g:

curl --location --request POST 'http://ipaddress:8093/v1/command/sendTo' \
--header 'Content-Type: application/json' \
--data-raw '{
"adapterInstance": "history.0",
"command": "getHistory",
"message": {"id": "system.adapter.admin.0.memRss","options": {"aggregate": "onchange", "addId": true}}
}'

You cannot send POST request to commands via GUI.

States

• getStates(pattern) - get the list of states for pattern (e.g. for system.adapter.admin.0.*). GUI can have problems by visualization of answer.
• getForeignStates(pattern) - same as getStates
• getState(id) - get state value by ID
• setState(id, state) - set state value with JSON object (e.g. {"val": 1, "ack": true})
• getBinaryState(id) - get binary state by ID
• setBinaryState(id, base64) - set binary state by ID

Objects

• getObject(id) - get object by ID
• getObjects() - get all states and rooms. GUI can have problems by visualization of answer.
• getObjectView(design, search, params) - get specific objects, e.g. design=system, search=state, params={"startkey": "system.adapter.admin.", "endkey": "system.adapter.admin.\u9999"}
• setObject(id, obj) - set object with JSON object (e.g. {"common": {"type": "boolean"}, "native": {}, "type": "state"})
• delObject(id, options) - delete object by ID

Files

• readFile(adapter, fileName) - read file, e.g. adapter=vis.0, fileName=main/vis-views.json. Additionally, you can set option in query binary=true to get answer as file and not as json
• readFile64(adapter, fileName) - read file as base64 string, e.g. adapter=vis.0, fileName=main/vis-views.json. Additionally, you can set option in query binary=true to get answer as file and not as json
• writeFile64(adapter, fileName, data64, options) - write file, e.g. adapter=vis.0, fileName=main/vis-test.json, data64=eyJhIjogMX0=
• unlink(adapter, name) - delete file or folder
• deleteFile(adapter, name) - delete file
• deleteFolder(adapter, name) - delete folder
• renameFile(adapter, oldName, newName) - rename file
• rename(adapter, oldName, newName) - rename file or folder
• mkdir(adapter, dirName) - create folder
• readDir(adapter, dirName, options) - read content of folder
• chmodFile(adapter, fileName, options) - change file mode. E.g. adapter=vis.0, fileName=main/*, options = {"mode": 0x644}

• fileExists(adapter, fileName) - check if file exists
