javascript - 将函数部署到 Firebase 时出错

Question

我正在尝试将功能部署到 Firebase

$ npm install firebase-tools
$ login firebase
$ firebase init functions

然后$firebasedeploy--onlyfunctions或$firebasedeploy

package.json:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "lint": "eslint .",
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "dependencies": {
    "firebase-admin": "~5.12.1",
    "firebase-functions": "^1.0.3"
  },
  "devDependencies": {
    "eslint": "^4.12.0",
    "eslint-plugin-promise": "^3.6.0"
  },
  "private": true
}

firebase.json:

{
  "functions": {
    "predeploy": [
      "npm --prefix \"%RESOURCE_DIR%\" run lint"
    ]
  }
}

将 $RESOURCE_DIR 编辑为 %RESOURCE_DIR% 以避免:

Error: functions predeploy error: Command terminated with non-zero exit code4294963238

我的函数index.js:

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

admin.initializeApp(functions.config().firebase);
var wrotedata;
exports.Pushtrigger = functions.database.ref('/messages/{messageId}').onWrite((event) => {
    wrotedata = event.data.val();

    admin.database().ref('/pushtokens').orderByChild('uid').once('value').then((alltokens) => {
        var rawtokens = alltokens.val();
        var tokens = [];
        this.processtokens(rawtokens).then((processedtokens) => {

            for (var token in processedtokens) {
                tokens.push(token.devtoken);
            }

            var payload = {
                "notification": {
                    "title": "Notification title",
                    "body": "Notification body",
                    "sound": "default",
                    "click_action": "FCM_PLUGIN_ACTIVITY",
                    "icon": "fcm_push_icon"
                },
                "data": {
                    "message": "value1",
                    "sendername": "value2"
                }
            }
                return admin.messaging().sendToDevice(tokens, payload).then((response) => {
                    console.log('Push notifications');
                }).catch((err) => {
                    console.log(err);
                })             
        })
    })
})

function processtokens(rawtokens) {
    var promise = new Promise((resolve, reject) => {
        var processedtokens = []
        for (token in rawtokens) {
            processedtokens.push(rawtokens[token]);
        }
        resolve(processdatatokens);
    })
    return promise;
}

我已经尝试过:

npm install firebase-admin@latest firebase-functions@latest
npm install -g git://github.com/firebase/firebase-tools#master

但是我得到了:

Error: functions predeploy error: Command terminated with non-zero exit code1

代码看起来有问题，因为默认 Hello from Firebase! 部署成功

编辑:

如果在 firebase.json 表单中将 \"%RESOURCE_DIR%\" 编辑为 "%RESOURCE_DIR%" ，错误为

Error: There was an error loading firebase.json: Unexpected token '%' "npm --prefix "%RESOURCE_DIR%" run lint"

如果我从 firebase.json 中删除行并在终端中运行 npm --prefix "%RESOURCE_DIR%"run lint:

npm ERR! enoent ENOENT: no such file or directory, open 'C:\Users\User\Desktop\pushcloud\%RESOURCE_DIR%\package.json'
npm ERR! enoent This is related to npm not being able to find a file.

npm ERR! C:\Users\User\AppData\Roaming\npm-cache\_logs\2018-07-13T11_33_25_593Z-debug.log 

但当 package.json 位于函数目录中时，目录文件夹作为 %RESOURCE_DIR% 与文件夹 etc 一起存在。如果我将其重新定位到 %RESOURCE_DIR%:

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! functions@ lint: `eslint .`

并使用$ firebase deploy --only 函数:

Answer 1

您的预部署标志 npm --prefix\"%RESOURCE_DIR%\"run lint 导致了您的问题。

如果您在终端中运行 npm --prefix "%RESOURCE_DIR%"run lint ，它是否正确运行而没有错误？

如果您从 firebase.json 中删除该行，那么它应该可以毫无问题地部署。

EDIT

检查您收到的错误消息，它可以为您提供答案。您的代码 linter 失败，您需要先修复这些错误，然后才能部署。

33:77  error    Each then() should return a value or throw  promise/always-return

我快速浏览了你的代码，我想我已经清理了它。此外，您不需要将 processtokens 设为 promise ，它是一个同步函数。

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

admin.initializeApp(functions.config().firebase);
var wrotedata;
exports.Pushtrigger = functions.database.ref('/messages/{messageId}').onWrite((event) => {
    wrotedata = event.data.val();

    return admin.database().ref('/pushtokens')
      .orderByChild('uid')
      .once('value')
      .then((alltokens) => {
        var rawtokens = alltokens.val();
        var tokens = [];

        var processedtokens = this.processtokens(rawtokens);

        for (var token in processedtokens) {
            tokens.push(token.devtoken);
        }

        var payload = {
            "notification": {
                "title": "Notification title",
                "body": "Notification body",
                "sound": "default",
                "click_action": "FCM_PLUGIN_ACTIVITY",
                "icon": "fcm_push_icon"
            },
            "data": {
                "message": "value1",
                "sendername": "value2"
            }
        };

        return admin.messaging().sendToDevice(tokens, payload).then((response) => {
            console.log('Push notifications');
        }).catch((err) => {
            console.log(err);
        })        
    })
})

function processtokens(rawtokens) {
    var processedtokens = []
    for (token in rawtokens) {
        processedtokens.push(rawtokens[token]);
    }

    return processdatatokens;
}
