Botframework V4:Messenger位置，电话和电子邮件快速回复 [英] Botframework V4: Messenger location, phone and email quick reply

问题描述

您好，我在此代码上向用户发送了带有位置的快速回复. 我将其放在文本提示中，以等待用户输入.但是在用户发送位置后，它在Messenger上产生了错误.我尝试输入文字和附件提示，但无法正常工作.

Hello i have this code on that sends a quick reply with location to the user. I put it in a text prompt to wait for user input. But its producing an error on messenger after the user sends it location. i tried text and attachment prompt but it is not working.

           Activity reply = stepContext.Context.Activity.CreateReply();

            reply.ChannelData = JObject.FromObject(
            new
            {
                text = "loc",
                quick_replies = new object[]
                {
                    new
                    {
                        content_type = "location",
                    },
                },
            });

            return await stepContext.PromptAsync(
               ATTACHPROMPT,
               new PromptOptions
               {
                   Prompt = reply,
               });
        }

我正在使用C#和Botframework V4

推荐答案

如果要通过文本或附件提示中的Facebook Messenger位置快速回复来捕获用户的位置，则需要提供自定义验证器-我建议您使用文字提示.

You need to provide a custom validator if you want to capture a user's location with Facebook Messenger's location quick reply in a Text or Attachment Prompt - I would recommend using a Text Prompt.

构造函数

创建瀑布并将提示添加到构造函数中的对话框堆栈中.确保将自定义验证器添加到文本提示；否则，该机器人会反复提示用户输入他们的位置，因为它期望快速回复无法提供的文本值.

Create your waterfall and add your prompts to the dialog stack in your constructor. Be sure to add a custom validator to the text prompt; otherwise, the bot will repeatedly prompt the user for their location since it is expecting a text value which the quick reply does not provide.

public MultiTurnPromptsBot(MultiTurnPromptsBotAccessors accessors)
{
    ...
    // This array defines how the Waterfall will execute.
    var waterfallSteps = new WaterfallStep[]
    {
        PromptForLocation,
        CaptureLocation,
    };
    ...
    // Add named dialogs to the DialogSet. These names are saved in the dialog state.
    _dialogs.Add(new WaterfallDialog("details", waterfallSteps));
    _dialogs.Add(new TextPrompt("location", LocationPromptValidatorAsync));

}

位置验证器

在自定义验证器中，您可以检查位置对象的传入活动，该活动位于活动的实体属性中.如果活动没有位置，则可以返回false，提示将再次询问用户其位置；否则，它将继续进行下一步.

In the custom validator, you can check the incoming activity for the location object, which is in the activity's entities property. If the activity doesn't have a location, you can return false and the prompt will ask the user for their location again; otherwise, it will continue onto the next step.

public Task<bool> LocationPromptValidatorAsync(PromptValidatorContext<string> promptContext, CancellationToken cancellationToken)
{
    var activity = promptContext.Context.Activity;
    var location = activity.Entities?.FirstOrDefault(e => e.Type == "Place");
    if (location != null) {
        return Task.FromResult(true);
    }
    return Task.FromResult(false);
}  

提示输入位置

与上面的代码段一样，您可以将Facebook Messenger快速回复添加到回复的频道数据.

As you had in your code snippet above, you can add the Facebook Messenger quick reply to the reply's channel data.

private static async Task<DialogTurnResult> PromptForLocation(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
    Activity reply = stepContext.Context.Activity.CreateReply();
    reply.Text = "What is your location?";
    reply.ChannelData = JObject.FromObject( new {

        quick_replies = new object[]
        {
            new
            {
                content_type = "location",
            },
        },
    });

    return await stepContext.PromptAsync("location", new PromptOptions { Prompt = reply }, cancellationToken);
}

捕获位置

您可以在此处捕获用户位置以使用所需的位置.

Here you can capture the user location to use how ever you'd like.

private async Task<DialogTurnResult> CaptureLocation(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{

    var activity = stepContext.Context.Activity;
    var location = activity.Entities?.FirstOrDefault(e => e.Type == "Place");
    if (location != null) {
        var latitude = location.Properties["geo"]?["latitude"].ToString();
        var longitude = location.Properties["geo"]?["longitude"].ToString();

        await stepContext.Context.SendActivityAsync($"Latitude: {latitude} Longitude: {longitude}");

    }
    // WaterfallStep always finishes with the end of the Waterfall or with another dialog, here it is the end.
    return await stepContext.EndDialogAsync(cancellationToken: cancellationToken);
}
