C# PDFTron Web Viewer在Azure中托管时未显示XOD文件
在我的ASP.NET页面上有一个PDFTron Web Viewer控件，我可以在其中成功查看PDFTron已在WebViewer文件夹中提供的静态文件“GettingStarted.xod”。该文件由ASP.NET web api REST服务返回。在本地运行解决方案时，文件显示成功。在Azure中托管时，我成功地从web api获取了文档，但是托管web viewer的网页没有显示文件，而是只显示一个空的web viewer控件。请建议如何在承载web viewer控件的ASP.NET页面中显示XOD。在WebViewer目录的settings.js文件中获取XOD文件的代码如下：-C# PDFTron Web Viewer在Azure中托管时未显示XOD文件,c#,azure,asp.net-web-api,pdftron,C#,Azure,Asp.net Web Api,Pdftron,在我的ASP.NET页面上有一个PDFTron Web Viewer控件，我可以在其中成功查看PDFTron已在WebViewer文件夹中提供的静态文件“GettingStarted.xod”。该文件由ASP.NET web api REST服务返回。在本地运行解决方案时，文件显示成功。在Azure中托管时，我成功地从web api获取了文档，但是托管web viewer的网页没有显示文件，而是只显示一个空的web viewer控件。请建议如何在承载web viewer控件的ASP.NET页面中

看起来您正在运行的WebViewer的旧版本没有azure特定的修复程序 您需要切换到最新版本。
您可以通过在Chrome中打开开发人员控制台来检查您的版本，在左上角有一个下拉列表，应该是，将其更改为ReaderControl.html，然后在控制台中运行ReaderControl.docViewer.version。根据Ryan的建议，我升级到了最新版本2.2.2。我离开了WebApi方法，使用PDF Tron Web Viewer作为MVC控制器，首先在Azure的托管文件夹中下载文件，然后在MVC Razor视图中显示文件。Azure上托管了什么？网页和XOD文件？如果没有，在哪里托管什么？任何浏览器都会出现这种情况吗？javascript控制台或浏览器中“开发人员”面板的“网络”选项卡中是否存在任何错误消息。请将此信息添加到您的问题中。@Rayn:是的，网页和XOD文件都托管在Azure中。是的，所有浏览器如MS Edge、Chrome等都会出现这种情况。我在帖子中添加了.aspx页面标记和浏览器控制台错误消息，供您参考。我看到一些用户在PDFTrom上提出了类似的问题，google group在Azure上托管XOD后未显示XOD；这些帖子的用户web查看器构造函数代码为var webViewer=new PDFTron.webViewer{}@Ryan：我看到的错误是：SCRIPT5022:codeError加载文档：无效的XOD文件：Zip端头数据大小错误！CoreControls.js 727381代码，如两篇文章中所述。请建议不要在代码窗口中显示streaming=true和azureWorkaround=false选项。WebViewerUniversalInstance.model.setI已从PDF网站下载了最新版本2.2.2。但是，当我通过选择ReaderControl.html并执行“ReaderControl.docViewer.version”在控制台窗口中检查版本时，我看到了1.7.1.24014。请提出建议。如下所示在Azure上工作，但不使用documentUrl$函数{var viewerElement=document.getElementById'viewer'；var myWebViewer=new PDFTron.WebViewer{path:'lib'，type:'html5'，documentType:xod，initialDoc:lib/GettingStarted.xod，config:，streaming:false，enableAnnotations:false，enableOfflineMode:false，enableReadOnlyMode:true}，viewerElement；}；您需要更新到WebViewer 2.2.2。特别是，这意味着用新文件夹替换lib文件夹。您看到的是1.7.1.24014，因为您没有成功更新版本。我首先要确保清除服务器和客户端浏览器上的所有缓存。可能您需要重新启动服务器。您还可以使用incognito/pr浏览器中的ivate模式。或者可能是您替换了错误的WebViewer/lib文件夹，而该服务器正在加载另一个文件夹。documentUrl参数不是新API的一部分，新API是围绕3个不同查看器（Silverlight、Flash和HTML5）的旧包装。HTML5是目前唯一受支持的，而新的WebViewer构造函数是一个initialDoc参数。我建议只在Azure服务器上运行stock SDK示例，以确保所有设置都正确，然后更新主项目。运行sock示例只需解压缩到服务器上的托管文件夹中。
