Suggest Belgio

Beta

Suggest a Belgium address field.

GEThttps://api.pro6pp.nl/v2/suggest/be/settlement

Panoramica

Returns settlement suggestions for a partly typed settlement.

How it works

  • Suggestions are generated from postnames. A postname is the official postal designation used by Bpost, which may differ from the administrative municipality or deelgemeente. For example, Laken is a postname within the municipality of Brussels.

  • If the languageCode parameter is omitted, results are returned in the country default language.

  • If the languageCode parameter is specified but no matches exist in that language, the API will fall back to the country default language.

  • postalCode or settlement is required.

ParametriQuery string

authKeystringObbligatorio

Every request needs an API key, which you can get in the portal.

When you call the API from a browser, visitors can see your API key. Limit it to your own domains in the portal, or send the requests through your own server so the key stays hidden.

Passo dopo passo

Seguendo i passaggi seguenti, crei un semplice modulo per provare la funzionalità Belgio Suggest.

  1. Creare la pagina HTML

    Iniziamo creando una pagina HTML vuota con una struttura web minima. Crei un nuovo file .html denominato pro6pp_belgio_suggest.html. Aggiunga il seguente codice tra i tag <body> e </body>. Questo codice aggiunge i campi di input per l'inserimento dell'indirizzo.

    pro6pp_belgio_suggest.html
    <form class="form" id="form">
      <div>Call</div>
      <div>
        <label for="settlement">settlement:</label>
        <input id="settlement" class="settlement" placeholder="Eupen"/>
        <label for="languageCode">languageCode:</label>
        <input id="languageCode" class="languageCode" placeholder=""/>
        <label for="postalCode">postalCode:</label>
        <input id="postalCode" class="postalCode" placeholder="4700"/>
        <label for="maxResults">maxResults:</label>
        <input id="maxResults" class="maxResults" placeholder=""/>
        <label for="cursor">cursor:</label>
        <input id="cursor" class="cursor" placeholder=""/>
      </div>
      <div>
        <span style="color: red" class="message"></span>
      </div>
      <div>
        <button type="submit">Submit</button>
      </div>
      <br />
      <div>Response</div>
      <br />
      <div>Full Response</div>
      <pre class="jsonResponse"></pre>
    </form>
  2. Aggiungere l'interazione

    Aggiunga il seguente codice JavaScript in un file separato pro6pp_belgio_suggest.js. Gli IDs e i nomi delle classi (Class) degli elementi HTML devono corrispondere a quelli indicati in questo file JavaScript per ottenere i risultati corretti.

    pro6pp_belgio_suggest.js
    document.addEventListener("DOMContentLoaded", function() {
        const pro6ppAuthKey = "AUTH_KEY"; // Replace with your actual authorization key
    
        let messageSpan = document.querySelector(".message");
        let jsonResponseSpan = document.querySelector(".jsonResponse");
        const BASE_URL = "https://api.pro6pp.nl/v2";
    
        function fetchAddress(authKey) {
            const queryParams = {
                authKey: authKey
            };
            const optionalQueryParams = [
                "settlement",
                "languageCode",
                "postalCode",
                "maxResults",
                "cursor",
            ];
            for (const name of optionalQueryParams) {
                const value = document.getElementById(name).value;
                if (value !== "") {
                    queryParams[name] = value;
                }
            }
    
            let encodedUrl = new URL(`${BASE_URL}/suggest/be/settlement`);
            encodedUrl.search = new URLSearchParams(queryParams);
    
            fetch(encodedUrl)
                .then(async (response) => {
                    const data = await response.json();
                    if (data) {
                        messageSpan.textContent = "";
                        jsonResponseSpan.textContent = JSON.stringify(data, null, 2);
                    }
                })
                .catch((error) => {
                    console.error("Error fetching: ", error);
                    messageSpan.textContent = error.message;
                });
        }
    
        const form = document.getElementById("form");
        form.onsubmit = function (event) {
            event.preventDefault();
            fetchAddress(pro6ppAuthKey);
        }
    });
  3. Farlo funzionare

    Colleghi il file JavaScript all'interno di pro6pp_belgio_suggest.html subito prima del tag di chiusura </body>.

    pro6pp_belgio_suggest.html
      ...
      <script src="pro6pp_belgio_suggest.js"></script>
     </body>
    </html>

    Per accedere al servizio web Pro6PP è necessario richiedere la Sua chiave di autorizzazione personale. La chiave Le viene inviata via e-mail subito dopo la registrazione. Sostituisca il segnaposto AUTH_KEY indicato sopra con la Sua chiave di autorizzazione personale.

    Se non ha ancora un account, si registri per una prova gratuita di 2 mesi. Dopo aver creato l'account, vada in Dettagli abbonamento e copi la Sua AUTH_KEY. Questa chiave Le servirà per autenticare le Sue richieste.

  4. Vederlo in azione

    Una volta completati i passaggi precedenti, è il momento di eseguire il modulo in locale nel Suo browser. Ora dovrebbe avere due file nella stessa cartella del Suo computer:

    • pro6pp_belgio_suggest.html - la pagina HTML con il modulo.
    • pro6pp_belgio_suggest.js - il file JavaScript che gestisce l'interazione.

    Ora può aprire il file HTML nel Suo browser semplicemente facendo doppio clic su di esso nel gestore file (ad es. Finder su macOS o File Explorer su Windows). In alternativa, può aprirlo manualmente nel browser utilizzando il percorso completo file:///. Ad esempio:

    Percorsi file di esempio
    file:///C:/Users/YourName/Documents/pro6pp_belgio_suggest.html
    file:///Users/yourname/Desktop/pro6pp_belgio_suggest.html

    Una volta aperta la pagina, inizi a digitare nei campi del modulo e prema Submit per visualizzare la risposta dell'API nella sezione "Full Response".
