Sample code sharing for ionic multi-image upload

This article mainly introduces the sample code for ionic to select multiple pictures to upload. The editor thinks it is quite good, so I will share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

In this section, I will share with you how to use Corodva's ImagePicker plug-in to select and upload multiple images. Without further ado, let’s get to the topic.

Plug-in installation

cordova plugin add corodva-plugin-imagepicker
cordova plugin add cordova-plugin-file-transfer

Define image selection service

angular.module('starter.services', [])
//配置单张图片选择
.factory('SelectPicture', function(UploadFile, Toast) {
 return {
 /**
  * 从图库选择多张图片
  */
 choosePictures: function() {
  window.imagePicker.getPictures(function(res){
  for(var i = 0; i < res.length; i++){
   UploadFile.uploadFile(res[i], "我的服务器接口地址");//传递自己的服务器接口地址
  }
  }, function(err){
  alert(err);
  }, {
  maximumImagesCount: 10, 
  quality: 80
  });
 }
 }
})

Define file upload service

//文件上传
.factory('UploadFile', function(Toast) {
 return {
 /**
  * 上传文件到服务器
  *
  * @param fileUrl 文件路径
  * @param server 服务器接口
  */
 uploadFile: function(fileUrl, server) {
  document.addEventListener("deviceready", onDeviceReady, false);
  function onDeviceReady() {
  var options = new FileUploadOptions();
  options.fileKey = "BeanYon";//后台获取文件的键值
  options.fileName = fileUrl.substr(fileUrl.lastIndexOf('/') + 1);
  options.mimeType = "image/jpeg";
  options.chunkedMode = false;

  var params = {};//这里可添加自定义参数
  options.params = params;

  var ft = new FileTransfer();
  ft.upload(fileUrl, 
     encodeURI(server), 
     success, 
     err, 
     options);
  }

  function success(r){
   Toast.show("图片已经成功上传");
  }

  function err(error){
   Toast.show("上传头像失败，请确保网络正常后再试");
  }
 }
 }
})

Call in Controller

angular.module('starter.controllers', [])
.controller('UsedUploadCtrl', function($scope, SelectPicture) {
 /**
 * 选择图片并上传
 */
 $scope.uploadImage = function(){
 SelectPicture.choosePictures($scope);
 }
})
