Microsoft BotFramework:集成FormFlow和Dialog与身份验证
本文关键字:Dialog 身份验证 FormFlow BotFramework 集成 Microsoft | 更新日期: 2023-09-27 18:05:58
我已经开发了一个机器人与MS bot框架使用对话框与Twitter上的身份验证过程。(我跟随facebook github项目)
我添加了一个业务逻辑流,阅读了MS文档,我遵循了FormFlow的最佳实践。
现在我有一个对话框与Twitter认证的核心和我的BL的FormFlow。目前我在合并Auth流程和BL流程方面遇到了困难。
我的目标是:
- 用户连接到bot并开始身份验证(对话框)
- 认证后,我想启动BL (FormFlow)
你有什么最好的合并方法吗?我可以运行我的FormFlow只有如果身份验证已经完成保持分离的实现?
部分代码
这是我的对话与授权
public static readonly IDialog<string> dialog = Chain
.PostToChain()
.Switch(
new Case<IMessageActivity, IDialog<string>>((msg) =>
{
var regex = new Regex("^login", RegexOptions.IgnoreCase);
return regex.IsMatch(msg.Text);
}, (ctx, msg) =>
{
// User wants to login, send the message to Twitter Auth Dialog
return Chain.ContinueWith(new SimpleTwitterAuthDialog(msg),
async (context, res) =>
{
// The Twitter Auth Dialog completed successfully and returend the access token in its results
var token = await res;
var name = await TwitterHelpers.GetTwitterProfileName(token);
context.UserData.SetValue("name", name);
context.PrivateConversationData.SetValue<bool>("isLogged", true);
return Chain.Return($"Your are logged in as: {name}");
});
}),
new DefaultCase<IMessageActivity, IDialog<string>>((ctx, msg) =>
{
string token;
string name = string.Empty;
if (ctx.PrivateConversationData.TryGetValue(AuthTokenKey, out token) && ctx.UserData.TryGetValue("name", out name))
{
var validationTask = TwitterHelpers.ValidateAccessToken(token);
validationTask.Wait();
if (validationTask.IsCompleted && validationTask.Result)
{
Chain.ContinueWith(new TwitterDialog(),
async (context2, res2) =>
{
var result2 = await res2;
return Chain.Return($"Done.");
});
return Chain.Return($"Your are logged in as: {name}");
}
else
{
return Chain.Return($"Your Token has expired! Say '"login'" to log you back in!");
}
}
else
{
return Chain.Return("Say '"login'" when you want to login to Twitter!");
}
})
).Unwrap().PostToUser();
这是我的FormFlow与BL
public static IForm<Tweet> BuildForm()
{
OnCompletionAsyncDelegate<Tweet> processTweet = async (context, state) =>
{
await context.PostAsync($"We are currently processing your tweet . We will message you the status. );
//...some code here ...
};
return new FormBuilder<Tweet>()
.Message("Tweet bot !")
.Field(nameof(TweetHashtags))
.Field(nameof(Tweet.DeliveryTime), "When do you want publish your tweet? {||}")`
.Confirm("Are you sure ?")
.AddRemainingFields()
.Message("Thanks, your tweet will be post!")
.OnCompletion(processTweet)
.Build();
这是控制器
public virtual async Task<HttpResponseMessage> Post([FromBody] Activity activity)
{
// QUESTION 1 :
// when user send the first message, How can I check if user is already logged in or not?
//QUESTION 2:
// Based on Question 1 answer, How can switch between Auth Dialog and FormFlow if user is not logged in ?
//QUESTION 3:
// is this the right place where I have to check the Question 1 and Question 2 or I have to do in another place ?
}
我将把它分成两个对话框,其中一个root对话框将确定用户是否经过身份验证。如果不是,您可以启动验证对话框;否则你可以直接调用FormFlow。
你不应该在控制器中执行检查。控制器应该只调用RootDialog。一般来说,当事情开始增长时,我更喜欢使用自定义对话框而不是Chain。
你可以看看AuthBot来了解这种方法是如何完成的。在示例中,您将看到有一个ActionDialog(一个根对话框),它在需要时调用AzureAuthDialog。
如果你想检查一个更复杂的样本;同样使用AuthBot和这种方法,请检查AzureBot。
