我得到以下异常
“System.Private.CoreLib:执行函数时发生异常:
Function1.Datalogics.PDFL:的类型初始值设定项
“Datalogics.PDFL.PDFLPINVOKE”引发了异常。Datalogics.PDFL:
“SwigeExceptionHelper”的类型初始值设定项引发异常。
Datalogics.PDFL:无法加载DLL“DL150PDFLPINVOKE”:指定的
找不到模块。(HRESULT异常:0x8007007E)。”
同样的代码也可以作为控制台应用程序使用。我在这里遗漏了什么?如果修复硬编码文件名仍然没有帮助,那么这个错误听起来像是权限异常 Azure函数在应用程序服务上运行,应用程序服务有一个用于所有代码的沙箱,其中一些调用是不允许的。例如,PDF生成库广泛使用的GDI32
阅读更多信息。感谢您通读问题并尝试回答 我发现,即使在添加了对Datalogics.PDFL.dll的引用之后,代码还是失败了 因此,我将所有其他dll复制到bin\debug文件夹中,现在代码工作正常 DL150ACE.dll DL150AdobeXMP.dll DL150AGM.dll DL150ARE.dll DL150AXE8SharedExpat.dll DL150BIB.dll DL150BIBUtils.dll DL150CoolType.dll DL150JP2KLib.dll DL150PDFL.dll DL150PDFLPINVOKE.dll DL150pdfport.dll DL150pdfsettings.dll DotNETViewerComponent.dll符合以下要求: Azure函数不支持在其当前版本中加载本机二进制文件。即使我们能够安装此软件包,在运行时加载这些本机DLL时,您仍然可能会遇到错误
因此,在尝试调用本机二进制文件时,这是预期的行为。如果您对开始使用PDF库还有任何疑问,请联系我们的支持部门。失败的代码行是“使用(库lib=new Library())”
