Infer Austria

Alpha

Suggest possible Austrian addresses from a string.

GEThttps://api.pro6pp.nl/v2/infer/at

Panoramica

Resolves a single query string into complete or probable addresses and returns a list of ranked suggestions. Each suggestion includes a stage indicating the current resolution step or completion status.

Stage meanings:

  • empty: returned on an empty query.
  • mixed: settlement and street suggestions.
  • postcode: postal code suggestions.
  • street_number: street number suggestions.
  • addition: street number addition suggestions.
  • direct: full address suggestions, with or without an addition.
  • final: a fully validated and structured address.

Street and settlement name matching:

  • One or two characters match names from the start (prefix).
  • Three or more characters match anywhere in the name: gebouw also finds Klokgebouw.
  • Matches are ranked by quality: the exact name first, then names the query starts, then matches beginning at a word boundary, then mid-word matches. Ties within a rank go to the name covering the most addresses.
  • When the names containing the query leave suggestion slots free, close matches fill them below the exact matches, absorbing typos.

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.

querystringObbligatorio

String to generate suggestions from.

Esempio
Innere Stadt, Babenberger
limitinteger

Maximum number of suggestions to return. Must be between 1 and 1000 when provided; omitting the parameter uses the default page size.

Min
1
Max
1000
sortstring

Sort mixed city and street suggestions by relevance (default) or distance. Distance sorting requires the Infer Extended (infer::location) capability. Distance sorting uses lat and lng when provided. Otherwise, it uses the approximate location derived from the request IP. If that location is unavailable, suggestions are sorted by relevance.

Passo dopo passo

Seguendo i passaggi seguenti, crei un semplice modulo per provare la funzionalità Austria Infer.

  1. Creare la pagina HTML

    Iniziamo creando una pagina HTML vuota con una struttura web minima. Crei un nuovo file .html denominato pro6pp_austria_infer.html. Aggiunga il seguente codice tra i tag <body> e </body>. Questo codice aggiunge i campi di input per l'inserimento dell'indirizzo.

    pro6pp_austria_infer.html
    <form class="form" id="form">
      <div>Call</div>
      <div>
        <label for="query">query:</label>
        <input id="query" class="query" placeholder="Innere Stadt, Babenberger"/>
        <label for="limit">limit:</label>
        <input id="limit" class="limit" placeholder=""/>
        <label for="sort">sort:</label>
        <input id="sort" class="sort" placeholder=""/>
        <label for="lat">lat:</label>
        <input id="lat" class="lat" placeholder=""/>
        <label for="lng">lng:</label>
        <input id="lng" class="lng" 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_austria_infer.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_austria_infer.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 = {
                query: document.getElementById("query").value,
                authKey: authKey
            };
            const optionalQueryParams = [
                "limit",
                "sort",
                "lat",
                "lng",
            ];
            for (const name of optionalQueryParams) {
                const value = document.getElementById(name).value;
                if (value !== "") {
                    queryParams[name] = value;
                }
            }
    
            let encodedUrl = new URL(`${BASE_URL}/infer/at`);
            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_austria_infer.html subito prima del tag di chiusura </body>.

    pro6pp_austria_infer.html
      ...
      <script src="pro6pp_austria_infer.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_austria_infer.html - la pagina HTML con il modulo.
    • pro6pp_austria_infer.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_austria_infer.html
    file:///Users/yourname/Desktop/pro6pp_austria_infer.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".
