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

Erhöhen Sie die intzwischen GrabzIt's Web Scraper und Ihre Anwendung mit GrabzIt's Web Scraper API zum programmgesteuerten Ändern der Eigenschaften von Web Scrapes.

Ändern Sie das Ziel eines Bahnkratzers

Das folgende Beispiel zeigt, wie Sie beide ändern Start-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 setze eine Variable zum string Array von Namen, die Variable kann jedoch auch auf einen anderen einfachen Datentyp festgelegt 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 auf normale Weise mit der Taste zugegriffen werden Global.get Methode wie unten gezeigt.

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

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