ich programmiere gerade meinen ersten Adapter und verzweifel gerade an einem einfachen HTTP Request. Um mich mit der Materie vertraut zu machen wollte ich erst einmal einen einfachen request, in diesem Fall "<a href="http://api.ipify.org/?format=json" rel="nofollow ugc">http://api.ipify.org/?format=json</a>" auslesen. Leider bekomme ich immer eine Fehlermeldung, wenn ich mir nur die Ausgabe anzeigen lassen möchte. Gleiches Problem, wenn ich über setState einen Status ändern möchte. Hier meine main.js:</p>
<pre><code>"use strict";

/*
 * Created with @iobroker/create-adapter v1.29.1
 */

// The adapter-core module gives you access to the core ioBroker functions
// you need to create an adapter
const utils = require("@iobroker/adapter-core");
var request = require('request');

// Load your modules here, e.g.:
// const fs = require("fs");

class Amadeus extends utils.Adapter {

	/**
	 * @param {Partial&lt;utils.AdapterOptions&gt;} [options={}]
	 */
	constructor(options) {
		super({
			...options,
			name: "amadeus",
		});
		this.on("ready", this.onReady.bind(this));
		this.on("stateChange", this.onStateChange.bind(this));
		// this.on("objectChange", this.onObjectChange.bind(this));
		// this.on("message", this.onMessage.bind(this));
		this.on("unload", this.onUnload.bind(this));
	}

	/**
	 * Is called when databases are connected and adapter received configuration.
	 */
	async onReady() {
		// Initialize your adapter here

		// The adapters config (in the instance object everything under the attribute "native") is accessible via
		// this.config:
		this.log.info("config option1: " + this.config.option1);
		this.log.info("config option2: " + this.config.option2);
		this.log.info("config option3: " + this.config.option3);

		/*
		For every state in the system there has to be also an object of type state
		Here a simple template for a boolean variable named "testVariable"

			common: {
				name: "testVariable",
				type: "boolean",

		this.subscribeStates("testVariable");
		// You can also add a subscription for multiple states. The following line watches all states starting with "lights."
		// this.subscribeStates("lights.*");
		// Or, if you really must, you can also watch all states. Don't do this if you don't need to. Otherwise this will cause a lot of unnecessary load on the system:
		// this.subscribeStates("*");

		/*
			setState examples
			you will notice that each setState will cause the stateChange event to fire (because of above subscribeStates cmd)
		*/
		// the variable testVariable is set to true as command (ack=false)
		await this.setStateAsync("testVariable", true);

		// same thing, but the value is flagged "ack"
		// ack should be always set to true if the value is received from or acknowledged from the target system
		await this.setStateAsync("testVariable", { val: true, ack: true });

		// same thing, but the state is deleted after 30s (getState will return null afterwards)
		await this.setStateAsync("testVariable", { val: true, ack: true, expire: 30 });

		// examples for the checkPassword/checkGroup functions
		let result = await this.checkPasswordAsync("admin", "iobroker");
		this.log.info("check user admin pw iobroker: " + result);

Mehrere Fehler:</p>
<ol>
<li>Zeile 95<br />
Du verwendest einen <code>function ()</code> callback, versuchst aber auf das <code>this</code> von außerhalb zuzugreifen. Das ist eine JavaScript-Eigenheit, dass <code>this</code> in manchen Funktionen keinen Wert hat. Zu diesem Zweck gibt es <a href="https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Functions/Pfeilfunktionen" rel="nofollow ugc">Arrow-Funktionen</a>:</li>
</ol>
<pre><code class="language-js">request(options, (error, response, body) =&gt; {
  ...
  // hier ist mit `this.` auch wirklich die Adapter-Instanz gemeint.
});
</code></pre>
<ol start="2">
<li>Zeile 97-99:<br />
<code>this.error</code>, <code>this.response</code> und <code>this.body</code> gibt es nicht. Lass hier das <code>this.</code> weg, du willst ja die Parameter der Funktion nutzen.</li>
</ol>
