详解ionic本地相册、拍照、裁剪、上传(单图完全版)

网络上已有的ionic图片选择上传博客碎片化过于严重,功能残缺或者引入了一些不必要的插件。这次以项目为契机,把ionic的图片选择、裁剪、上传整合一下,多图上传请戳ionic选择多张图片上传

插件安装

cordova plugin add cordova-plugin-camera //用于通过相机、相册选择图片并完成裁剪
cordova plugin add cordova-plugin-file-transfer //用于上传图片到服务器

将功能封装为服务

angular.module('starter.services', [])

//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";
  options.fileName = fileUrl.substr(fileUrl.lastIndexOf('/') + 1);
  options.mimeType = "image/jpeg";
  options.chunkedMode = false;

  var params = {account: localStorage.account};
  options.params = params;

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

  function success(r){
  Toast.show("设置头像成功");
  }

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

//配置单张图片选择
.factory('SelectPicture', function(UploadFile, Toast) {
 return {
 /**
  * 从相机或图库选择一张图片
  * 
  * @param type 选择类型,0 拍照,1 相册
  * @param width 目标宽度
  * @param height 目标高度
  * @param scope $scope对象
  */
 chooseSinglePicture: function(type, width, height, scope) {
  document.addEventListener("deviceready", onDeviceReady, false);
  function onDeviceReady() {
  var options = {//相机配置
   targetWidth: width,
   targetHeight: height,
   quality: 100,
   allowEdit: true
  }

  if(type == 1){//图片源设置为相册
   options.sourceType = 2;
  }

  navigator.camera.getPicture(
   function(res){
   scope.avatar_src = res;
   scope.$apply();
   localStorage.avatar = res;
   UploadFile.uploadFile(res, "我的服务器地址");//传递自己的服务器接口地址
   }, function(res){
   Toast.show("选择头像失败");
   }, options
  );
  }
 },

 /**
  * 从图库选择多张图片
  */
 choosePictures: function() {
  window.imagePicker.getPictures(function(res){
  alert(res+",success");
  }, function(res){
  alert(res+",failed");
  }, {
  maximumImagesCount: 10, 
  width: 80, 
  height: 80, 
  quality: 80 
  });
 }
 }
});

调用服务

angular.module('starter.controllers', [])
.controller('MyCtrl', function($scope, $state, $ionicActionSheet, UploadFile,Toast, SelectPicture) {
 $scope.avatar_src = "img/default_avatar.jpg";

 /**
 *选择头像
 */
 $scope.selectAvatar = function(){
 // 显示操作表
 $ionicActionSheet.show({
  buttons: [
  { text: '<p style="font-size: 18px;">拍照<p>' },
  { text: '<p style="font-size: 18px;">从相册选择<p>' },
  ],
  buttonClicked: function(index) {
  //设置头像
  SelectPicture.chooseSinglePicture(index, 120, 120, $scope);
  return true;
  }
 });
 }
})
