此問題已於 IronOCR 2024.3.4 版本中解決。
Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronOCR must be licensed for development.
針對較舊的 IronOCR 版本,特別是 2023.4.13 至 2024.3.4 之間的版本,存在已知授權問題:
- ASP.NET 專案
- .NET Framework 版本 >= 4.6.2
儲存於 Web.co/nfig 檔案中的金鑰,本產品將不會讀取或使用。
解決方案
為解決此問題,建議在程式碼中使用 ConfigurationManager 從 Web.co/nfig 檔案中擷取授權金鑰,然後將其套用至 License.LicenseKey 屬性。
範例:
<configuration>
...
<appSettings>
<add key="IronOcr.LicenseKey" value="IRONOCR-MYLICENSE-KEY-1EF01"/>
</appSettings>
...
</configuration>
<configuration>
...
<appSettings>
<add key="IronOcr.LicenseKey" value="IRONOCR-MYLICENSE-KEY-1EF01"/>
</appSettings>
...
</configuration>
XML
透過上述提供的 XML 檔案,我們可以使用 ConfigurationManager 擷取授權金鑰值,並將其傳遞給 IronOcr.License.LicenseKey 屬性。
using System.Co/nfiguration;
// Retrieve the license key from the Web.co/nfig's appSettings
string licenseKey = ConfigurationManager.AppSettings["IronOcr.LicenseKey"];
// Apply the license key to IronOcr to avoid licensing exceptions
IronOcr.License.LicenseKey = licenseKey;
using System.Co/nfiguration;
// Retrieve the license key from the Web.co/nfig's appSettings
string licenseKey = ConfigurationManager.AppSettings["IronOcr.LicenseKey"];
// Apply the license key to IronOcr to avoid licensing exceptions
IronOcr.License.LicenseKey = licenseKey;
Imports System.Configuration
' Retrieve the license key from the Web.config's appSettings
Dim licenseKey As String = ConfigurationManager.AppSettings("IronOcr.LicenseKey")
' Apply the license key to IronOcr to avoid licensing exceptions
IronOcr.License.LicenseKey = licenseKey
