在发布具有连续部署的漫游器后，图像不会显示

我使用Bot Framework开发了一个机器人。当我在Bot Framework Emulator上本地运行它时，它会显示图像。但是在通过创建私有GitHub存储库将其发布在Azure上之后，没有显示任何图像。我正在使用Direct-Line API 3.0。可能是什么原因？

就像，这是我的项目的树状视图。 images文件夹位于Content Root中。

Project Tree View

我正在使用以下静态方法来检索图像路径。

public static string CreateImagePath(string filename)
    {
        return Path.Combine(TempData.HostingEnvironment?.ContentRootPath, "images", $"{filename}");
    }

然后将其转换为Uri，并将其分配给Adaptive Card的映像。这是代码段。

(AdaptiveCardFactory.CreateAdaptiveElement(card, "image") as AdaptiveImage).Url =
            new Uri(PathFactory.CreateImagePath("welcome_card_image.png"));

CreateAdaptiveElement定义为：

public static AdaptiveElement CreateAdaptiveElement(AdaptiveCard card, string adaptiveElementId)
    {
        return card.Body.Find(ae => ae.Id == adaptiveElementId);
    }

这是我在本地运行机器人时返回的Uri。它工作正常。 

file:///C:/Users/Husai/source/repos/PanjaSahibBot/images/welcome_card_image.png

这是发布后返回的内容。

file:///D:/home/site/wwwroot/images/welcome_card_image.png

而且，它不起作用。

这是我所期望的。 Locally executed 而且，这就是我通过DirectLine得到的东西！ Actual result

这是我的welcome_card.json的内容

我已经定义了AdaptiveCardFactory以使用卡进行操作。

public class AdaptiveCardFactory
{
    public static AdaptiveCard CreateAdaptiveCard(string path)
    {
        try
        {
            var adaptiveCardJson = File.ReadAllText(path);
            AdaptiveCardParseResult result = AdaptiveCard.FromJson(adaptiveCardJson);
             return result.Card;
        }
        catch (AdaptiveSerializationException)
        {
            throw;
        }
    }

    public static Attachment CreateAdaptiveCardAttachment(AdaptiveCard card)
    {
        return new Attachment
        {
            ContentType = "application/vnd.microsoft.card.adaptive",
            Content = card,
        };
    }

    public static AdaptiveElement CreateAdaptiveElement(AdaptiveCard card, string adaptiveElementId)
    {
        return card.Body.Find(ae => ae.Id == adaptiveElementId);
    }
}

答案 0 :(得分：2)

TL; DR;

您必须为AdaptiveCard中显示的项目提供公共URL，而不是本地URL。它与模拟器一起在本地工作，因为...您在本地，并且模拟器可以访问您的本地文件，因此它可以理解具有本地位置的文件（C:\...或D:\...文件）。

因此，请更改路径，以使其使用您的子域：您可以在此处执行此操作，例如，使用配置变量代替TempData.HostingEnvironment?.ContentRootPath 

public static string CreateImagePath(string filename)
{
    return Path.Combine(TempData.HostingEnvironment?.ContentRootPath, "images", $"{filename}");
}

详细信息：

AdaptiveCard项目作为bot消息中的附件传递，内部的所有内容均由客户端（渠道）呈现，因此它只能呈现从外部“可见”的内容。

在这里查看我的演示：我使用了一张具有2张图像的ImageSet的卡：一个带有Web上的URL，另一个带有类似您的URL的构建。

本地：两个图像都可以。 enter image description here

已发布：仅显示第1张图像 Published

如果您查看右侧的检查器，很明显，您必须更改构建图像网址的方式。

您还可以通过右键单击图像所在的区域来查看已部署的网络聊天，您将找到一个带有D:\...路径的链接

代码修复

首先，将images文件夹移至projet的wwwroot文件夹内。然后，您可以执行以下操作：

public string CreateImagePath(string filename)
{
    if (_hostingEnvironment.IsDevelopment())
    {
        return Path.Combine(TempData.HostingEnvironment?.ContentRootPath, "wwwroot", "images", $"{filename}");
    }
    else
    {
        var targetUri = new Uri(new Uri($"https://{Environment.ExpandEnvironmentVariables("%WEBSITE_SITE_NAME%")}.azurewebsites.net"), Path.Combine("images", $"{filename}"));
        return targetUri.ToString();
    }
}
