Azure WebJobs上的ABCPDF Gecko

Question

让ABCPDF Gecko Engine将网页转换为PDF。 在本地工作正常，但是当推向天蓝色的webjobs时，我不知道该如何调试。 我不确定这行代码（3518）是什么，因为有不同的版本，并且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

当部署为Azure webjob时，ABCpdf Gecko引擎会失败，而是可以部署为Azure云服务（经典）Web角色。

仅在需要将图像或HTML转换为PDF的情况下才需要WebRole。 如果仅需要将文本转换为PDF，我们可以将应用程序托管为App Service或WebJob（可能不需要WebRole或Cloud Service）。

不幸的是，由于沙箱限制，我认为这在Azure网站中不起作用。
