GDI +中发生一般性错误。在Azure上的webapp [英] A generic error occurred in GDI+. on Azure Webapp

问题描述

我使用的塔尖lib中创建PDF文件的用户。

I am using spire lib to create pdf files for the user.

    string userId = User.Identity.GetUserId();
        User trainee = _userDAL.GetUserByIdentityId(userId);

        // Get the Employee scores
        string fileNameTemplate = Server.MapPath(Url.Content("~/assets/cert1-{0}-{1}.docx"));
        string nnn = string.Format("cert1-{0}-{1}.pdf", trainee.StaffID, DateTime.Now.Millisecond);
        string serverPath = MainConfig.P_EXPORT;
        var folder = Server.MapPath(serverPath);

使用（文档document_test =新的文件（））
            {
 document_test.LoadFromFile（fileNameTemplate）;

using (Document document_test = new Document()) { document_test.LoadFromFile(fileNameTemplate);

            //Update Text of Title
            document_test.Replace("#trainee_name#", trainee.Name, false, true);
            document_test.Replace("#course_name#", "Test", false, true);
            document_test.Replace("#date_info#", DateTime.Today.ToShortDateString(), false, true);

            document_test.SaveToFile(nnn, Spire.Doc.FileFormat.PDF, System.Web.HttpContext.Current.Response, HttpContentType.Attachment);
        }

在code完美的作品在本地开发机器上，但是当我把它上传到Azure的Web应用程序，我得到一本普通的错误：GDI +中发生一般性错误。

The Code works perfectly on the local development machine, but when i upload it to Azure web app i get a this generic error: A generic error occurred in GDI+.

推荐答案

这是Azure的Web应用程序下运行的沙箱具有阻止某些调用一些限制，这很可能是你与GDI +运行到什么

The sandbox that Azure Web Apps run under has some restrictions which blocks certain calls, which is likely what you're running into with GDI+.

您可以找到关于<一个沙盒的那些限制的更多信息href=\"https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#win32ksys-user32gdi32-restrictions\" rel=\"nofollow\">https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#win32ksys-user32gdi32-restrictions.
