Semalt: Come usare jQuery.Ajax in un'estensione di Google Chrome

Oggigiorno, i web scraper usano strumenti di scraping web di alto livello per estrarre dati utili dal web pagine in formati utilizzabili. Questi strumenti di scraping web comprendono funzionalità pre-confezionate che consentono di creare un piano efficace (sitemap) su come un sito Web deve essere navigato e raschiato.

Perché jQuery.ajax?

L'estrazione dei dati Web è definita come la soluzione definitiva per estrarre automaticamente le informazioni dal web. Se stai lavorando per estrarre informazioni da siti dinamici, la prima cosa che devi fare è verificare se il sito comprende o meno un'interfaccia API (Application Programming Interface) ufficiale.

In genere, tutti i dati che possono essere visualizzati sui siti Web e le pagine Web di e-commerce possono essere estratti automaticamente. Nell'attuale settore del marketing online, i siti hanno un'importanza maggiore rispetto alle API. È qui che entra in gioco jQuery.ajax. I proprietari dei siti Web si concentrano sul miglioramento dell'impegno potenziato con i potenziali visitatori rispetto al mantenimento dei loro feed di dati.

Asynchronous JavaScript and XML (AJAX) è una tecnologia euristica che consente ai professionisti del marketing di caricare i dati dal server primario aggiornando la pagina del browser. Con AJAX, è possibile caricare i dati di destinazione sullo sfondo della macchina e visualizzarli su una pagina Web senza ricaricare l'intera pagina.

Utilizzando jQuery.ajax nel plugin Chrome

jQuery è un'estensione di Ajax Chrome, ampiamente utilizzata nel settore del marketing per inviare richieste di scraping Web. Applicazioni come Google Maps, Facebook e Gmail utilizzano l'intero esercizio delle loro attività. Ecco i parametri comuni che specificano i valori utilizzati in una richiesta Ajax:

  •  Async - Questo valore di estensione Ajax di Chrome indica se il numero totale di richieste inviate deve essere eseguito in modo asincrono o no;
  •  Cache - Il valore della cache indica se Google Chrome deve memorizzare nella cache le pagine Web richieste. Si noti che la funzione "Prima di inviare" viene eseguita prima che una richiesta venga inviata alle pagine Web di destinazione;
  •  Context - Questa estensione di Ajax Chrome specifica il valore principale di tutte le funzioni di callback basate su Ajax;
  •  ProcessData - W Quando si tratta di utilizzare AJAX, questo valore specifica se i dati inviati con richieste devono essere completamente trasformati in una stringa di query o meno. Nota che il parametro URL richiesto specifica l'URL che preferisci caricare.

Che cosa è necessario sapere su jQuery e AJAX

L'estrazione di dati da siti Web sviluppati utilizzando la tecnologia euristica può essere un po 'complicata. Con le tecniche jQuery AJAX appropriate, puoi richiedere rapidamente JSON, XML o HTML da un server in remoto utilizzando sia HTTP Post che HTTP Get. Nota che jQuery offre un vasto numero di funzionalità AJAX.

Browser diversi contengono sintassi diverse per ogni implementazione AJAX. Pertanto, è necessario scrivere più codici per browser diversi come Mozilla, Google Chrome e Internet Explorer. Fortunatamente, puoi caricare i dati esterni direttamente negli elementi HTML precedentemente selezionati della pagina web di destinazione.

Nella maggior parte dei casi, jQuery utilizza i metodi "GET" e "POST" per richiedere dati da risorse specifiche e inviare informazioni da elaborare su risorse specificate. Per impostazione predefinita, tutte le richieste vengono inviate in modo asincrono (Vero). Per utilizzare le applicazioni simultanee, impostare l'opzione asincrona come falsa. Utilizza l'estensione jQuery.Ajax Chrome per facilitare la tua campagna di scraping web e ottenere dati accurati e strutturati.
