azure - 从 Azure 函数中的 Url 生成 PDF 时出现 IronPDF System.Exception 错误

Question

我有一个 Azure(持久)函数，它使用新的运行时版本 3，该函数应该使用 IronPDF 从 URL 生成 PDF。该函数不断失败，记录到 Insights 的唯一错误如下:

Exception: Exception while executing function: A_GetPdfDataFromUrl
Type: Microsoft.Azure.WebJobs.Host.FunctionInvocationException


Stack Trace

不幸的是，由于当前版本中存在错误，IronPDF 日志不会在 Azure 中生成，他们表示该错误将在下一版本中修复。所以在那之前我无法弄清楚为什么这个简单的代码在 Azure 中失败。

[FunctionName("A_GetPdfDataFromUrl")]
public async Task<byte[]> GetPdfDataFromUrl([ActivityTrigger] string url)
{
    IronPdf.License.LicenseKey = "";
    IronPdf.Logging.Logger.EnableDebugging = true;
    IronPdf.Logging.Logger.LoggingMode = IronPdf.Logging.Logger.LoggingModes.All;

    ChromePdfRenderer chromePdfRenderer = new ChromePdfRenderer();
    

    var trackReportPdf = chromePdfRenderer.RenderUrlAsPdf(url);

    return trackReportPdf.BinaryData;
}

谢谢darren 。将您的建议作为答案发布以帮助其他社区成员。

日志将在 Azure 中生成，所有日志将存储在名为 $logs 的容器中。容器$logs是在创建存储帐户时自动生成的。

All logs are stored in block blobs in a container named $logs.
This is automatically created when Storage Analytics is enabled for a storage account.
The $logs container is located in the blob namespace of the storage account

回答您的问题Raihan-Iqbal

Do you mean the storage account that is assigned to the azure function

是的，我们在创建 Azure Function 时创建的存储帐户，或者它可能是 $logs 容器将自动生成的任何存储帐户。
