建立 IronWebscraper 範例的步驟

1. 建立一個資料夾並將其命名為"HelloScraperSample"

2. 接著新增一個類別，並將其命名為 HelloScraper

3. 將此程式碼片段加入 HelloScraper

   public class HelloScraper : WebScraper
   {
       /// <summary>
       /// Override this method to initialize your web scraper.
       /// Important tasks will be to request at least one start URL and set allowed/banned domain or URL patterns.
       /// </summary>
       public override void Init()
       {
           License.LicenseKey = "LicenseKey"; // Write License Key
           this.LoggingLevel = WebScraper.LogLevel.All; // Log all events
           this.Request("https://blog.scrapinghub.com", Parse); // Initialize a web request to the given URL
       }
   
       /// <summary>

       public override void Parse(Response response)
       {
           // Set working directory for the project
           this.WorkingDirectory = AppSetting.GetAppRoot() + @"\HelloScraperSample\Output\";
           // Loop on all links
           foreach (var titleLink in response.Css("h2.entry-title a"))
           {
               // Read link text
               string title = titleLink.TextContentClean;
               // Save result to file
               Scrape(new ScrapedData() { { "Title", title } }, "HelloScraper.json");
           }
   
           // Loop on all links for pagination
           if (response.CssExists("div.prev-post > a[href]"))
           {
               // Get next page URL
               var nextPage = response.Css("div.prev-post > a[href]")[0].Attributes["href"];
               // Scrape next URL
               this.Request(nextPage, Parse);
           }
       }
   }

   public class HelloScraper : WebScraper
   {
       /// <summary>
       /// Override this method to initialize your web scraper.
       /// Important tasks will be to request at least one start URL and set allowed/banned domain or URL patterns.
       /// </summary>
       public override void Init()
       {
           License.LicenseKey = "LicenseKey"; // Write License Key
           this.LoggingLevel = WebScraper.LogLevel.All; // Log all events
           this.Request("https://blog.scrapinghub.com", Parse); // Initialize a web request to the given URL
       }
   
       /// <summary>
       /// Override this method to create the default Response handler for your web scraper.
       /// If you have multiple page types, you can add additional similar methods.
       /// </summary>
       /// <param name="response">The HTTP Response object to parse</param>
       public override void Parse(Response response)
       {
           // Set working directory for the project
           this.WorkingDirectory = AppSetting.GetAppRoot() + @"\HelloScraperSample\Output\";
           // Loop on all links
           foreach (var titleLink in response.Css("h2.entry-title a"))
           {
               // Read link text
               string title = titleLink.TextContentClean;
               // Save result to file
               Scrape(new ScrapedData() { { "Title", title } }, "HelloScraper.json");
           }
   
           // Loop on all links for pagination
           if (response.CssExists("div.prev-post > a[href]"))
           {
               // Get next page URL
               var nextPage = response.Css("div.prev-post > a[href]")[0].Attributes["href"];
               // Scrape next URL
               this.Request(nextPage, Parse);
           }
       }
   }

   Public Class HelloScraper
   	Inherits WebScraper
   
   	''' <summary>
   	''' Override this method to initialize your web scraper.
   	''' Important tasks will be to request at least one start URL and set allowed/banned domain or URL patterns.
   	''' </summary>
   	Public Overrides Sub Init()
   		License.LicenseKey = "LicenseKey" ' Write License Key
   		Me.LoggingLevel = WebScraper.LogLevel.All ' Log all events
   		Me.Request("https://blog.scrapinghub.com", AddressOf Parse) ' Initialize a web request to the given URL
   	End Sub
   
   	''' <summary>
   	''' Override this method to create the default Response handler for your web scraper.
   	''' If you have multiple page types, you can add additional similar methods.
   	''' </summary>
   	''' <param name="response">The HTTP Response object to parse</param>
   	Public Overrides Sub Parse(ByVal response As Response)
   		' Set working directory for the project
   		Me.WorkingDirectory = AppSetting.GetAppRoot() & "\HelloScraperSample\Output\"
   		' Loop on all links
   		For Each titleLink In response.Css("h2.entry-title a")
   			' Read link text

   			' Save result to file
   			Scrape(New ScrapedData() From {
   				{ "Title", title }
   			},
   			"HelloScraper.json")
   		Next titleLink
   
   		' Loop on all links for pagination

   			Dim nextPage = response.Css("div.prev-post > a[href]")(0).Attributes("href")
   			' Scrape next URL
   			Me.Request(nextPage, AddressOf Parse)
   		End If
   	End Sub
   End Class

   $vbLabelText   $csharpLabel

4. 現在要開始進行抓取，請將此程式碼片段加入 Main

   static void Main(string[] args)
   {
       // Create Object From Hello Scrape class
       HelloScraperSample.HelloScraper scrape = new HelloScraperSample.HelloScraper();
       // Start Scraping
       scrape.Start();
   }

   static void Main(string[] args)
   {
       // Create Object From Hello Scrape class
       HelloScraperSample.HelloScraper scrape = new HelloScraperSample.HelloScraper();
       // Start Scraping
       scrape.Start();
   }

   Shared Sub Main(ByVal args() As String)
   	' Create Object From Hello Scrape class
   	Dim scrape As New HelloScraperSample.HelloScraper()
   	' Start Scraping
   	scrape.Start()
   End Sub

   $vbLabelText   $csharpLabel
5. 翻譯結果將儲存於格式為 WebScraper.WorkingDirectory/classname.Json 的檔案中

程式碼概覽

Scrape.Start() 會以以下方式觸發擷取邏輯：

1. 呼叫 Init() 方法以初始化變數、擷取屬性及行為屬性。
2. 使用 Request("https://blog.scrapinghub.com", Parse) 設定 Init() 中的起始頁面請求。
3. 能並行處理多個 HTTP 請求與執行緒，使程式碼保持同步並更易於除錯。
4. Parse() 方法會在 Init() 之後觸發，以處理回應，透過 CSS 選擇器擷取資料，並將其儲存為 JSON 格式。

抓取線上電影網站

讓我們建立一個範例，來抓取電影網站的資料。

新增一個類別並將其命名為 MovieScraper：

HTML 結構

以下是網站首頁 HTML 中的部分內容：

            <span class="mli-info"><h2>Snatched</h2></span>
        </a>
    </div>
</div>

如我們所見，這裡包含電影 ID、標題以及詳細頁面連結。 讓我們開始抓取這些資料：

public class MovieScraper : WebScraper
{
    public override void Init()
    {
        License.LicenseKey = "LicenseKey";
        this.LoggingLevel = WebScraper.LogLevel.All;
        this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
        this.Request("www.website.com", Parse);
    }

    public override void Parse(Response response)
    {
        foreach (var div in response.Css("#movie-featured > div"))
        {
            if (div.GetAttribute("class") != "clearfix")
            {
                var movieId = div.GetAttribute("data-movie-id");
                var link = div.Css("a")[0];
                var movieTitle = link.TextContentClean;
                Scrape(new ScrapedData() { { "MovieId", movieId }, { "MovieTitle", movieTitle } }, "Movie.Jsonl");
            }
        }           
    }
}

public class MovieScraper : WebScraper
{
    public override void Init()
    {
        License.LicenseKey = "LicenseKey";
        this.LoggingLevel = WebScraper.LogLevel.All;
        this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
        this.Request("www.website.com", Parse);
    }

    public override void Parse(Response response)
    {
        foreach (var div in response.Css("#movie-featured > div"))
        {
            if (div.GetAttribute("class") != "clearfix")
            {
                var movieId = div.GetAttribute("data-movie-id");
                var link = div.Css("a")[0];
                var movieTitle = link.TextContentClean;
                Scrape(new ScrapedData() { { "MovieId", movieId }, { "MovieTitle", movieTitle } }, "Movie.Jsonl");
            }
        }           
    }
}

Public Class MovieScraper
	Inherits WebScraper

	Public Overrides Sub Init()
		License.LicenseKey = "LicenseKey"
		Me.LoggingLevel = WebScraper.LogLevel.All
		Me.WorkingDirectory = AppSetting.GetAppRoot() & "\MovieSample\Output\"
		Me.Request("www.website.com", AddressOf Parse)
	End Sub

	Public Overrides Sub Parse(ByVal response As Response)
		For Each div In response.Css("#movie-featured > div")
			If div.GetAttribute("class") <> "clearfix" Then
				Dim movieId = div.GetAttribute("data-movie-id")
				Dim link = div.Css("a")(0)
				Dim movieTitle = link.TextContentClean
				Scrape(New ScrapedData() From {
					{ "MovieId", movieId },
					{ "MovieTitle", movieTitle }
				},
				"Movie.Jsonl")
			End If
		Next div
	End Sub
End Class

結構化 Movie 類別

為了存放格式化的資料，讓我們實作一個電影類別：

public class Movie
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string URL { get; set; }
}

public class Movie
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string URL { get; set; }
}

Public Class Movie
    Public Property Id As Integer
    Public Property Title As String
    Public Property URL As String
End Class

現在請更新我們的程式碼，以使用 Movie 類別：

public class MovieScraper : WebScraper
{
    public override void Init()
    {
        License.LicenseKey = "LicenseKey";
        this.LoggingLevel = WebScraper.LogLevel.All;
        this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
        this.Request("https://website.com/", Parse);
    }

    public override void Parse(Response response)
    {
        foreach (var div in response.Css("#movie-featured > div"))
        {
            if (div.GetAttribute("class") != "clearfix")
            {
                var movie = new Movie
                {
                    Id = Convert.ToInt32(div.GetAttribute("data-movie-id")),
                    Title = div.Css("a")[0].TextContentClean,
                    URL = div.Css("a")[0].Attributes["href"]
                };
                Scrape(movie, "Movie.Jsonl");
            }
        }
    }
}

public class MovieScraper : WebScraper
{
    public override void Init()
    {
        License.LicenseKey = "LicenseKey";
        this.LoggingLevel = WebScraper.LogLevel.All;
        this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
        this.Request("https://website.com/", Parse);
    }

    public override void Parse(Response response)
    {
        foreach (var div in response.Css("#movie-featured > div"))
        {
            if (div.GetAttribute("class") != "clearfix")
            {
                var movie = new Movie
                {
                    Id = Convert.ToInt32(div.GetAttribute("data-movie-id")),
                    Title = div.Css("a")[0].TextContentClean,
                    URL = div.Css("a")[0].Attributes["href"]
                };
                Scrape(movie, "Movie.Jsonl");
            }
        }
    }
}

Public Class MovieScraper
	Inherits WebScraper

	Public Overrides Sub Init()
		License.LicenseKey = "LicenseKey"
		Me.LoggingLevel = WebScraper.LogLevel.All
		Me.WorkingDirectory = AppSetting.GetAppRoot() & "\MovieSample\Output\"
		Me.Request("https://website.com/", AddressOf Parse)
	End Sub

	Public Overrides Sub Parse(ByVal response As Response)
		For Each div In response.Css("#movie-featured > div")
			If div.GetAttribute("class") <> "clearfix" Then
				Dim movie As New Movie With {
					.Id = Convert.ToInt32(div.GetAttribute("data-movie-id")),
					.Title = div.Css("a")(0).TextContentClean,
					.URL = div.Css("a")(0).Attributes("href")
				}
				Scrape(movie, "Movie.Jsonl")
			End If
		Next div
	End Sub
End Class

詳細頁面抓取

讓我們擴充我們的 Movie 類別，新增用於詳細資訊的屬性：

public class Movie
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string URL { get; set; }
    public string Description { get; set; }
    public List<string> Genre { get; set; }
    public List<string> Actor { get; set; }
}

public class Movie
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string URL { get; set; }
    public string Description { get; set; }
    public List<string> Genre { get; set; }
    public List<string> Actor { get; set; }
}

Public Class Movie
    Public Property Id As Integer
    Public Property Title As String
    Public Property URL As String
    Public Property Description As String
    Public Property Genre As List(Of String)
    Public Property Actor As List(Of String)
End Class

接著導航至"詳細資訊"頁面進行擷取，並運用 IronWebscraper 的進階功能：

public class MovieScraper : WebScraper
{
    public override void Init()
    {
        License.LicenseKey = "LicenseKey";
        this.LoggingLevel = WebScraper.LogLevel.All;
        this.WorkingDirectory = AppSetting.GetAppRoot() + @"\MovieSample\Output\";
        this.Request("https://domain/", Parse);
    }

    public override void Parse(Response response)
    {
        foreach (var div in response.Css("#movie-featured > div"))
        {
            if (div.GetAttribute("class") != "clearfix")
            {
                var movie = new Movie
                {
                    Id = Convert.ToInt32(div.GetAttribute("data-movie-id")),
                    Title = div.Css("a")[0].TextContentClean,
                    URL = div.Css("a")[0].Attributes["href"]
                };
                this.Request(movie.URL, ParseDetails, new MetaData() { { "movie", movie } });
            }
        }           
    }

    public void ParseDetails(Response response)
    {
        var movie = response.MetaData.Get<Movie>("movie");
        var div = response.Css("div.mvic-desc")[0];
        movie.Description = div.Css("div.desc")[0].TextContentClean;
        movie.Genre = div.Css("div > p > a").Select(element => element.TextContentClean).ToList();
        movie.Actor = div.Css("div > p:nth-child(2) > a").Select(element => element.TextContentClean).ToList();

        Scrape(movie, "Movie.Jsonl");
    }

HttpIdentity 功能

某些系統要求使用者必須登入才能瀏覽內容； 請使用 HttpIdentity 作為憑證：

HttpIdentity id = new HttpIdentity
{
    NetworkUsername = "username",
    NetworkPassword = "pwd"
};
Identities.Add(id);

HttpIdentity id = new HttpIdentity
{
    NetworkUsername = "username",
    NetworkPassword = "pwd"
};
Identities.Add(id);

Dim id As New HttpIdentity With {
	.NetworkUsername = "username",
	.NetworkPassword = "pwd"
}
Identities.Add(id)

啟用網頁快取

在開發過程中將請求的頁面快取以供重複使用：

public override void Init()
{
    License.LicenseKey = "LicenseKey";
    this.LoggingLevel = WebScraper.LogLevel.All;
    this.WorkingDirectory = AppSetting.GetAppRoot() + @"\ShoppingSiteSample\Output\";
    EnableWebCache();
    this.Request("http://www.WebSite.com", Parse);
}

public override void Init()
{
    License.LicenseKey = "LicenseKey";
    this.LoggingLevel = WebScraper.LogLevel.All;
    this.WorkingDirectory = AppSetting.GetAppRoot() + @"\ShoppingSiteSample\Output\";
    EnableWebCache();
    this.Request("http://www.WebSite.com", Parse);
}

Public Overrides Sub Init()
