Question

我们正在使用Firebase云功能来实现目标，并使用外部rest api来进行原始操作。

我们打算进行一些后续跟踪，看起来像这样

 - Create Note
 - - Create Note - fallback*
 - - - Create Note - fallback - yes
 - - - Create Note - fallback - no

* the fallback allows us to capture free text

在我们的网络挂钩中，我实现了以下目标

app.intent("Create Note", (conv) => {
    if (!conv.user.storage.note) conv.user.storage.note = {};
    conv.ask("Go ahead, talk to Talkatoo!");
});

app.intent("Create Note - fallback", (conv) => {
    conv.user.storage.input = conv.input.raw;

    let response = conv.user.storage.note
         ? conv.user.storage.note.body.concat(conv.input.raw)
         : conv.user.storage.input;

    conv.ask("So far this is what I heard you say, let me know if this is complete. ", response);
});

app.intent("Create Note - fallback - yes", (conv) => {
    // based on the conv.user.storage.note object
    // either make a call to create a note or update a note

    // make call to external api and based on the response 
    // set the value for conv.user.storage.note

   conv.ask("Great news, let me save that for you!");
});

app.intent("Create Note - fallback - no", (conv) => {
    // based on the conv.user.storage.note object
    // either make a call to create a note or update a note

    // make call to external api and based on the response 
    // set the value for conv.user.storage.note

    // Send the user back to Create Note to capture the rest of their input
   conv.followup("my_custom_event");
});

问题是当我从API获得响应时，conv.user.storage.note被设置了，但是随后它被重置为空，因此每次都创建一个新注释。我正在尝试将用户的各种输入附加为一个便笺

基于...

app.intent("Create Note - fallback - yes", (conv) => {
    // based on the conv.user.storage.note object
    // either make a call to create a note or update a note

    // make call to external api and based on the response 
    // set the value for conv.user.storage.note

   conv.ask("Great news, let me save that for you!");
});

您似乎尚未编写API调用的代码，或者在发布到StackOverflow上之前已删除了该代码。正确吗？

您能否更新问题以显示将HTTP请求发送到外部REST API的位置和方式？

对于可能最终对您有所帮助的任何人，我发现了一条帖子，并意识到处理异步调用的响应可能需要更多的思考（以解决问题）How to make asynchronous calls from external services to actions on google?

对于我们的用例，我们不需要响应数据，即，我们不需要将任何响应数据传达给用户，因此我们将用户的多个输入保存在user.storage中，并在它们完成时保存我们保存了完整的回复。

app.intent("Intent - fallback", (conv) => {
    conv.user.storage.input = conv.user.storage.input
    ? conv.user.storage.input.concat(conv.input.raw)
    : conv.input.raw;

    conv.ask("Is that complete or would you like to continue?");
});

app.intent("Intent - fallback - yes", (conv) => {

    createNote(conv); <--- makes call to save

    conv.ask("Great news, let me save that for you!");
});

app.intent("Intent - fallback - no", (conv) => {
    conv.followup("my_custom_event");
});

如何通过响应外部API将数据保存在存储中
