从购物网站抓取内容
This article was translated from English: Does it need improvement?
TranslatedView the article in English
我们选择一个购物网站，从中抓取内容
如图所示，左侧栏包含网站产品类别的链接
因此，我们的第一步是研究网站的 HTML，并计划如何进行搜索。
时尚网站类别有子类别 (男士、女士、儿童)

让我们建立一个项目
1.创建一个新的控制台应用程序，或为我们的新示例添加一个新文件夹，名称为 "ShoppingSiteSample"。
2.添加名称为 "ShoppingScraper "的新类
3.第一步是搜索网站类别及其子类别
让我们创建一个类别模型：
public class Category

/// The name.
/// </value>
public string Name { get; set; }
/// <summary>

/// <value>
/// The URL.
/// </value>
public string URL { get; set; }
/// <summary>
/// Gets or sets the sub categories.
/// </summary>
/// <value>
/// The sub categories.
/// </value>
public List<Category> SubCategories { get; set; }
}public class Category
{
/// <summary>

/// The name.

public string Name { get; set; }

/// The URL.
/// </value>
public string URL { get; set; }
/// <summary>
/// Gets or sets the sub categories.
/// </summary>
/// <value>
/// The sub categories.
/// </value>
public List<Category> SubCategories { get; set; }
}Public Class Category
''' <summary>
''' Gets or sets the name.
''' </summary>
''' <value>
''' The name.
''' </value>
Public Property Name() As String
''' <summary>
''' Gets or sets the URL.

''' The URL.

Public Property URL() As String
''' <summary>
''' Gets or sets the sub categories.

Public Property SubCategories() As List(Of Category)

为了抓取分类页面，我们添加了一种新的抓取方法：
public void ParseCatgory(Response response)
{
// List of Products Links (Root)
var productList = new List<Product>();
foreach (var Links in response.Css("body > main > section.osh-content > section.products > div > a"))
{
var product = new Product();
product.Name = Links.InnerText;
product.Image = Links.Css("div.image-wrapper.default-state > img")[0].Attributes ["src"];
productList.Add(product);
}
Scrape(productList, "Products.Jsonl");
}public void ParseCatgory(Response response)
{
// List of Products Links (Root)
var productList = new List<Product>();
foreach (var Links in response.Css("body > main > section.osh-content > section.products > div > a"))
{
var product = new Product();
product.Name = Links.InnerText;
product.Image = Links.Css("div.image-wrapper.default-state > img")[0].Attributes ["src"];
productList.Add(product);
}
Scrape(productList, "Products.Jsonl");
}Public Sub ParseCatgory(ByVal response As Response)
' List of Products Links (Root)
Dim productList = New List(Of Product)()
For Each Links In response.Css("body > main > section.osh-content > section.products > div > a")
Dim product As New Product()
product.Name = Links.InnerText
product.Image = Links.Css("div.image-wrapper.default-state > img")(0).Attributes ("src")
productList.Add(product)
Next Links
Scrape(productList, "Products.Jsonl")
