使用持续部署发布机器人后不显示图像

Question

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 存储库将其发布到 Azure 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，这是我的项目的树视图。图片文件夹位于 Content Root 中。

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，并将其分配给自适应卡片的图像。这是代码sn-p。

(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。

这是最新的命令日志。

这是我所期待的。 Locally executed 而且，这就是我通过 DirectLine 得到的！！ Actual result

这是我的welcome_card.json 的内容

我已经定义了 AdaptiveCardFactory 来操作卡片。

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);
    }
}

Answer 1

TL;DR;

您必须为 AdaptiveCards 中显示的项目提供公共 URL，而不是本地项目。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）。

所以改变你的路径，让它使用你的子域：你可以在这里做，例如使用配置变量而不是TempData.HostingEnvironment?.ContentRootPath

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

详情：

AdaptiveCard item 在 bot 消息中作为附件传递，内部的所有内容都由客户端（通道）渲染，因此它只能渲染从外部“可见”的内容。

在此处查看我的演示：我使用了一张带有 2 张图片的 ImageSet 的卡片：一张带有 Web 上的 URL，另一张带有类似您的 URL 构建。

本地：两个图像都可以。

已发布：仅显示第一张图片

如果您查看右侧的 Inspector，很明显您必须更改构建图像 Url 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

1st，将您的images 文件夹移动到您的项目的wwwroot 文件夹中。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();
    }
}
