ts code

home.ts 中的代码:

顶部

import { Component } from '@angular/core';
import { FirebaseProvider } from './../../providers/firebase/firebase';
import { FirebaseListObservable } from 'angularfire2/database';
import { NavController, NavParams } from 'ionic-angular';
import { BarcodeScanner ,BarcodeScannerOptions } from '@ionic-native/barcode-scanner';
import { Request } from '@angular/http';


@Component({
selector: 'home',
templateUrl: 'home.html',
})

//警报功能

scanAlert(){
    this.options = {
      showFlipCameraButton : true,
      formats : "QR_CODE,PDF_417", 
      prompt : "SCAN QR CODE "
    }
    this.barcodeScanner.scan(this.options).then((barcodeData) => {
        console.log(barcodeData);
        this.pinText = barcodeData.text;
        const uid = this.pinText;
        this.firebaseProvider.afd.database.ref('pins')
        .orderByChild('QRCODE')
        .equalTo(uid)
        .limitToFirst(1)
        .once('value', snap => {
            let key = Object.keys(snap.val())[0]; // KEY VALUE 
            let user = snap.child(key).val(); // the whole user object
            this.message = 'Parameters to send to twilio' + user.phone + 
                  'regarding'+user.message;

            const accountSid = 'myacctid';
            const authToken = 'mytoken';

            // require the Twilio module and create a REST client
            const client = require('twilio')(accountSid, authToken);

            client.messages
            .create({
                to: '+142mynumber  ',
                from: '+mysms trial#',
                body: 'TEST Alert Message !',
  })
  .then((message) => console.log(message.sid));

我遵循了这些步骤

安装需要--保存

和

npm install @types/node --save-dev

我的问题是消息未发送。

如果我添加

declare var require: any    

错误消失了，但 twilio 从未收到发送消息的请求。 enter image description here

我找不到任何 Ionic3 或 Angular 和 twilio 发送短信的教程我连参数都没有传，我复制了

这个我也试过

    var twilio = require('twilio');//Make sure to npm install @types/node
    var accountSid = 'myacctid'; // Your Account SID from www.twilio.com/console
    var authToken = 'myauthtoken';   // Your Auth Token from www.twilio.com/console


    var client = new twilio(accountSid, authToken);

    client.messages.create({
        body: 'ALERT! Someone has scanned the Alert Code for ',
        to: '+myphone'  ,// Text this number
        from: '+myTwilioTrial#' // From a valid Twilio number
    })
    .then((message) => console.log(message.sid));

我的 tsconfig.json:

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,

添加:

"types": [
    "node"
],
"typeRoots": [
    "node_modules/@types"
]

在tsconfig.json文件中
