不要从 Firestore 获取数据

Question

伙计们，谁能向我解释为什么我无法从 Firestore 中读取数据？我已经阅读了文档并多次查看了路径，但仍然看不到它。我在做离子

   getChat(chatId){
        const chatRoom = this.firestore.collection('/business/').doc(chatId);
        const room = chatRoom.get();
        console.log(room);
      }

Observable {_isScalar: false, source: Observable, operator: ObserveOnOperator}
operator: ObserveOnOperator {scheduler: ɵZoneScheduler, delay: 0}
source: Observable {_isScalar: false, _subscribe: ƒ}
_isScalar: false
__proto__: Object

Answer 1

试试这个：复制此代码后检查所有括号和“chatId”是否正确

getChat(chatId){
        const chatRoom = this.firestore.collection('/business/').doc(chatId);
        const room = chatRoom.get().subscribe(o => {
             console.log(k.data());              
        })
      }
