1.官网：

　　https://ionicframework.com/docs/native/camera/#DestinationType

2.引入插件

$ ionic cordova plugin add cordova-plugin-camera$ npm install --save @ionic-native/camera

3.在app.module.ts里面引用

　　import { Camera } from '@ionic-native/camera';

　　

　　providers:[ Camera ]

4.新建一个CameraPage 用来作例子

　　ts：

import { Component } from '@angular/core';import { IonicPage, NavController, NavParams } from 'ionic-angular';import { Camera,CameraOptions } from '@ionic-native/camera';/** * Generated class for the CameraPage page. * * See https://ionicframework.com/docs/components/#navigation for more info on * Ionic pages and navigation. */@IonicPage()@Component({  selector: 'page-camera',  templateUrl: 'camera.html',})export class CameraPage {  public base64Image;  constructor(public navCtrl: NavController, public navParams: NavParams,public camera:Camera) {  }  doCamera(){    const options: CameraOptions = {      quality: 70,//图片质量      destinationType: this.camera.DestinationType.DATA_URL,//返回base64地址      encodingType: this.camera.EncodingType.JPEG,           sourceType:this.camera.PictureSourceType.CAMERA,      // mediaType: this.camera.MediaType.PICTURE,      allowEdit:true,      targetWidth:300,  /*宽度高度要设置*/      targetHeight:300,      saveToPhotoAlbum:true,     }    this.camera.getPicture(options).then((imageData) => {      this.base64Image = 'data:image/jpeg;base64,'+imageData; //拍照地址      console.log(this.base64Image);     }, (err) => {     });  }}

　　html：

       
      拍照  
        
      {
   {base64Image}}
     

5.照相机参数
