Aumentare il integrazione tra GrabzIt Raschietto Web e la tua applicazione utilizzando GrabzIt's API del raschietto web per modificare a livello di codice le proprietà degli scrap web.
L'esempio seguente mostra come modificare entrambi i file URL seed e il principale URL di destinazione.
GrabzItScrapeClient client = new GrabzItScrapeClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
Target target = new Target();
//Set the target URL
target.URL = "http://www.example.com";
List<string> seedUrls = new List<string>();
seedUrls.Add("http://www.example.com/news.html");
seedUrls.Add("http://www.example.com/about.html");
seedUrls.Add("http://www.example.com/contactus.html");
//Set the seed URL's
target.SeedURLs = seedUrls.ToArray();
//Enter the id of the scrape you want to alter along with the target object
client.SetScrapeProperty("59421f049e3d991318d35e49", target);
$client = new GrabzItScrapeClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
$target = new GrabzItTarget();
//Set the target URL
$target->SetURL("http://www.example.com");
$seedUrls = array();
$seedUrls[] = "http://www.example.com/news.html";
$seedUrls[] = "http://www.example.com/about.html";
$seedUrls[] = "http://www.example.com/contactus.html";
//Set the seed URL's
$target->SetSeedURLs($seedUrls);
//Enter the id of the scrape you want to alter along with the target object
$client->SetScrapeProperty("59421f049e3d991318d35e49", $target);
client = GrabzItScrapeClient.GrabzItScrapeClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
target = new GrabzItTarget.GrabzItTarget()
#Set the target URL
target.url = "http://www.example.com"
seedUrls = []
seedUrls.append("http://www.example.com/news.html")
seedUrls.append("http://www.example.com/about.html")
seedUrls.append("http://www.example.com/contactus.html")
#Set the seed URL's
target.seedURLs = seedUrls
#Enter the id of the scrape you want to alter along with the target object
client.SetScrapeProperty("59421f049e3d991318d35e49", target)
Negli esempi seguenti noi imposta una variabile ad un string matrice di nomi, tuttavia la variabile può anche essere impostata su qualsiasi altro tipo di dati semplici.
GrabzItScrapeClient client = new GrabzItScrapeClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
Variable variable = new Variable("names");
List<string> names = new List<string>();
names.Add("Tom");
names.Add("Dick");
names.Add("Harry");
foreach(string name in names)
{
variable.AddArrayItem(name);
}
//Enter the id of the scrape you want to alter along with the variable object
client.SetScrapeProperty("59421f049e3d991318d35e49", variable);
$client = new GrabzItScrapeClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
$variable = new GrabzItVariable("names");
$names = array();
$names[] = "Tom";
$names[] = "Dick";
$names[] = "Harry";
$variable->SetValue($names);
//Enter the id of the scrape you want to alter along with the variable object
$client->SetScrapeProperty("59421f049e3d991318d35e49", $variable);
client = GrabzItScrapeClient.GrabzItScrapeClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
variable = new GrabzItVariable.GrabzItVariable("names")
names = []
names.append("Tom")
names.append("Dick")
names.append("Harry")
#Set the seed URL's
variable.value = names
#Enter the id of the scrape you want to alter along with the variable object
client.SetScrapeProperty("59421f049e3d991318d35e49", variable)
È quindi possibile accedere al valore della variabile normalmente utilizzando il comando Global.get metodo come mostrato di seguito.
var names = Global.get("names");
L'array dei nomi può quindi essere utilizzato normalmente nelle istruzioni di scraping.
