Hoe verander je een scrape met de GrabzIt's Web Scraper API?

Verhogen intintegratie tussen GrabzIt's Webschraper en uw toepassing met behulp van GrabzIt's Web Scraper API om de eigenschappen van webschrappen programmatisch te wijzigen.

Wijzig het doel van een webschraap

Het onderstaande voorbeeld laat zien hoe u beide kunt wijzigen seed URL's en de belangrijkste doel-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)

Wijzig een variabele in een webscrape

In de onderstaande voorbeelden we stel een variabele in een string reeks namen, maar de variabele kan ook worden ingesteld op elk ander type eenvoudige gegevens.

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)

De variabele waarde kan vervolgens op de normale manier worden geopend met behulp van de Global.get methode zoals hieronder getoond.

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

De namenmatrix kan dan normaal worden gebruikt in de instructies voor het schrapen.
