Comment modifier une éraflure à l'aide de l'API Web Scraper de GrabzIt?

Augmenter le intintégration entre GrabzIt's Grattoir Web et votre application en utilisant GrabzIt's API Web Scraper pour modifier par programme les propriétés des éraflures Web.

Modifier la cible d'une éraflure Web

L’exemple ci-dessous montre comment changer à la fois URL de départ et le principal Cible URL.

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)

Modifier une variable dans une gratte Web

Dans les exemples ci-dessous, nous définir une variable à string tableau de noms, mais la variable peut également être définie sur tout autre type de données simples.

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)

La valeur de la variable est alors accessible de manière normale à l’aide de la touche Global.get méthode comme indiqué ci-dessous.

var names = Global.get("names");

Le tableau de noms peut ensuite être utilisé normalement dans les instructions de scrap.
