Wie kann man ein Scrape mit der GrabzIt Web Scraper API ändern?

Erhöhen Sie die intEgration zwischen GrabzIt's Web Scraper und Ihre Bewerbung mit GrabzIt's Web Scraper-API um die Eigenschaften von Web-Scrapes programmgesteuert zu ändern.

Ändern Sie das Ziel eines Web-Scrapes

Das folgende Beispiel zeigt, wie man beides ändert Seed-URLs und die wichtigsten Ziel-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)

Ändern Sie eine Variable in einem Web-Scrape

In den folgenden Beispielen haben wir Legen Sie eine Variable fest zum string Es handelt sich um ein Array mit Namen, die Variable kann jedoch auch auf jede andere Art einfacher Daten gesetzt werden.

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)

Auf den Variablenwert kann dann wie gewohnt über zugegriffen werden Global.get Methode wie unten gezeigt.

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

Das Namensarray kann dann wie gewohnt in den Scrape-Anweisungen verwendet werden.
