Azure WebJobs上的ABCPDF Gecko

Question

有ABCPDF Gecko引擎将网页转换为PDF。在本地运行得很好，但在使用azure webjob时，我不知道如何调试它。我不确定这行代码(3518)是什么，因为有不同的版本，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

当部署为Azure webjob时，ABCpdf Gecko引擎会失败，而您可以将其部署为Azure云服务(经典) Web角色。

只有在需要将图像或超文本标记语言转换为WebRole的情况下，才需要PDF。如果只需要将文本转换为PDF，我们可以将应用程序托管为App Service或WebJob (WebRole或云服务可能不是必需的)。

这里提供了ABCpdf Azure部署指南：

不幸的是，由于沙箱的限制，我不认为这可以在Azure网站上工作。
