问题已在 IronWebScraper 版本 2024.3.6 中解决。

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项目
.NET Framework版本 >= 4.6.2

存储在 Web.config 文件中的密钥将不会被产品拾取和使用。

解决方法

为了解决这个问题，建议在代码中使用ConfigurationManager从 Web.config 文件中检索许可证密钥，然后应用到 License.LicenseKey 属性。

示例：

<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，我们可以使用ConfigurationManager检索许可证密钥值，并将其传递给IronWebScraper.License.LicenseKey属性。

// 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
