Scraping-Toolkit

Read this in other language: English, Portuguese

Overview

The Scrapping-Toolkit is a fast-based structure to capture information within web pages, used to track websites and even extract or insert data on the web pages. It can be widely used to reach to any goal from data-mining to web site monitoring and automated tests.

Prerequisites

or superior

How to use

To install the component you can use the "Install" command or access https://www.nuget.org/packages/Scraping/

Install-Package Scraping

To make it use the "load", you must inform the url (FromUrl) and one usage possibility is to let the tool try to identify the screen components.

public void LoadComponents()
{
	var ret = new HttpRequestFluent(true)
		.FromUrl("https://github.com/otavioalfenas/Scraping-Toolkit")
		.TryGetComponents(Scraping.Enums.TypeComponent.LinkButton| Scraping.Enums.TypeComponent.InputHidden)
		.Load();
}

Inside the tool, there are also many extensions that make the parse work easier.

public void AllTags()
{
	var ret = new HttpRequestFluent(true)
		.FromUrl("https://github.com/otavioalfenas/Scraping-Toolkit")
		.Load();
	var byClassContain = ret.HtmlPage.GetByClassNameContains("Box mb-3 Box--");
	var byClassEquals = ret.HtmlPage.GetByClassNameEquals("Box mb-3 Box--condensed");
	var byId = ret.HtmlPage.GetById("readme");
}

Examples

Below there is an example of all the methods inside the Load. The folder "test" contains many examples on Load usage and extensions. If any doubt or suggestion comes up, you may contact us or open an issue so we can improve the tool together.

public void LoagPageFull()
{
	var ret = new HttpRequestFluent(true);
	ret.OnLoad += Ret_OnLoad;
	NameValueCollection parameters = new NameValueCollection();
	parameters.Add("Name", "Value");

	ret.FromUrl("https://github.com/otavioalfenas/Scraping-Toolkit")
		.TryGetComponents(Enums.TypeComponent.ComboBox| Enums.TypeComponent.DataGrid| 
						Enums.TypeComponent.Image|Enums.TypeComponent.InputCheckbox|
						Enums.TypeComponent.InputHidden| Enums.TypeComponent.InputText|
						Enums.TypeComponent.LinkButton)
		.RemoveHeader("name")
		.AddHeader("name", "value")
		.KeepAlive(true)
		.WithAccept("Accept")
		.WithAcceptEncoding("Accept-Encoding")
		.WithAcceptLanguage("Accept-Language")
		.WithAutoRedirect(true)
		.WithContentType("ContentType")
		.WithMaxRedirect(2)
		.WithParameters(parameters)
		.WithPreAuthenticate(true)
		.WithReferer("Referer")
		.WithRequestedWith("WithRequestedWidth")
		.WithTimeoutRequest(100)
		.WithUserAgent("User-Agent")
	.Load();

}

private void Ret_OnLoad(object sender, RequestHttpEventArgs e)
{
	e.HtmlPage;
	e.ResponseHttp;
}
