Firebase Firestore可与实际数据库一起使用，但不能与模拟器一起使用 [英] Firebase Firestore works with real database but not emulator
问题描述
我正在使用Firebase，并且已经开始尝试使用Firebase模拟器运行本地开发实例.我正在运行Firebase Tools v8.4.1.当我使用真实的Firestore数据库运行时，一切正常.但是，当我使用仿真器时出了点问题.
I'm using Firebase and have started trying to run a local development instance using the Firebase Emulators. I'm running v8.4.1 of Firebase Tools. When I'm running with the real Firestore database everything works fine. However there is something wrong when I'm using the emulators.
当我通过Firebase模拟器添加数据时，我可以设置一个文档，然后通过Javascript 获取，但是在Firebase Emulators UI中没有任何显示，反之亦然在UI中，使用Javascript中的 get 时不可用.另外，当我使用Firebase Tools CLI的导入和导出功能时，我通过Javascript添加的所有数据都不会导出和导入.我在浏览器控制台中没有任何错误.
I can set a document and then get it through Javascript but nothing shows in the Firebase Emulators UI and the same in reverse, when I add data through the Firebase Emulators UI it isn't available using get in Javascript. Also, when I use the import and export function of the Firebase Tools CLI none of the data I've added through Javascript is exported and imported. I'm not getting any errors in the browser console.
我不确定初始化Firebase或我缺少的其他一些配置时是否做错了什么?
I'm not sure if there is something wrong I'm doing in initializing Firebase or some other config I'm missing?
我正在运行: firebase模拟器:start --only功能，firestore

推荐答案
原来，该问题是由于Firebase Tools的当前状态引起的.我以前一直在将Firebase Tools与另一个项目一起使用，并且必须对要与以下模拟器一起使用的当前项目运行 use 命令:
Turns out the issue was due to the current status of Firebase Tools. I had previously been using Firebase Tools with another project and had to run the use command for my current project that I was trying to use the emulators with:
firebase use project_name
现在一切正常.
这篇关于Firebase Firestore可与实际数据库一起使用，但不能与模拟器一起使用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
