c# - Azure WebJobs 上的 ABCPDF Gecko

Question

使用 ABCPDF Gecko Engine 将网页转换为 PDF。在本地工作正常，但是当推送到 azure webjobs 时，我不知道如何调试它。我不确定那行代码(3518)是什么，因为有不同的版本，并且它从没有代码的地方抛出错误。

C# 代码

    var url = "http://www.woot.com";
    Log("AddingImageUrl {0}", url);
    var theID = _doc.AddImageUrl(url);
    while (true)
    {
        if (!_doc.Chainable(theID))
        {
            break;
        }
        _doc.Page = _doc.AddPage();
        SetupRectangle();
        theID = _doc.AddImageToChain(theID);
    }

Answer 1

ABCpdf Gecko 引擎在部署为 Azure Web 作业时失败，但您可以部署为 Azure 云服务(经典)Web 角色。

仅当图像或 HTML 需要转换为 PDF 时才需要 WebRole。如果仅需要将文本转换为 PDF，我们只需将应用程序托管为应用服务或 WebJob(可能不需要 WebRole 或云服务)。
