該問題已於 IronWebScraper 版本 2024.3.6 解決。

Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronWebScraper must be licensed for development.

For older IronWebScraper versions, specifically those between versions 2023.4.13 and 2024.3.6, there is a known licensing issue in:

ASP.NET 專案
.NET Framework 版本 >= 4.6.2

Web.config 檔中存儲的密鑰將不會被產品檢測並使用。

解決方案

為解決此問題，建議在代碼中使用 ConfigurationManager 從 Web.config 文件中檢索許可證密鑰，然後將其應用於 License.LicenseKey 屬性。

範例：

<configuration>
  ...
  <appSettings>
    <add key="IronWebScraper.LicenseKey" value="IRONWEBSCRAPER-MYLICENSE-KEY-1EF01"/>
  </appSettings>
  ...
</configuration>

<configuration>
  ...
  <appSettings>
    <add key="IronWebScraper.LicenseKey" value="IRONWEBSCRAPER-MYLICENSE-KEY-1EF01"/>
  </appSettings>
  ...
</configuration>

XML

使用上面提供的 XML 文件，我們可以使用 ConfigurationManager 來檢索許可證密鑰值並將其傳遞給 IronWebScraper.License.LicenseKey 屬性。

// Retrieve the license key from the appSettings section of the Web.config file.
string licenseKey = ConfigurationManager.AppSettings["IronWebScraper.LicenseKey"];

// Assign the license key to the IronWebScraper's LicenseKey property.
IronWebScraper.License.LicenseKey = licenseKey;

// Retrieve the license key from the appSettings section of the Web.config file.
string licenseKey = ConfigurationManager.AppSettings["IronWebScraper.LicenseKey"];

// Assign the license key to the IronWebScraper's LicenseKey property.
IronWebScraper.License.LicenseKey = licenseKey;

' Retrieve the license key from the appSettings section of the Web.config file.
Dim licenseKey As String = ConfigurationManager.AppSettings("IronWebScraper.LicenseKey")

' Assign the license key to the IronWebScraper's LicenseKey property.
IronWebScraper.License.LicenseKey = licenseKey
