javascript - 无法在 firestore 数据库中添加多个字段，但在添加单个字段时工作正常

Question

我的index.js文件:

const functions = require('firebase-functions');

const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {

 let action = request.body.result.action;

 var Name = request.body.result.parameters.Name;

 var Answer1 = request.body.result.parameters.Answer1;

  let query = request.body.result.resolvedQuery;

    const parameters = request.body.result.parameters; 

    const inputContexts = request.body.result.contexts; 



     if(action === 'save.name'  || inputContexts == 'welcome'  && action === 'save.answer1' || inputContexts == 'question1'){

                  admin.firestore().collection('users').doc('details').collection('user1').add({
                         name: Name ,
                       answer1 : Answer1

                    }).then(ref => {
                      console.log('Added new user');
                      console.log('name' +Name);
                      console.log('answer1' +Answer1);
                    });

    } 
});

当我尝试将所有用户详细信息存储在下面时，我收到类似 admin.firestore(...).collection(...).document.add is not a function文档“详细信息”。此代码只是尝试检查是否可以在同一文档中添加更多字段! 我正在使用 api v1 聊天机器人

您收到此错误是因为 Firestore 库不支持 add 方法。您正在寻找 set 方法。更改此行:

admin.firestore().collection('users').doc('details').collection('user1').add({

对此:

admin.firestore().collection('users').doc('details').collection('user1').set({
