这篇文章主要介绍ionic本地相册、拍照、裁剪、上传的示例分析，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
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 {
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 {
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.$apply();
localStorage.avatar = res;
UploadFile.uploadFile(res, "我的服务器地址");//传递自己的服务器接口地址
}, function(res){
Toast.show("选择头像失败");
}, options
);
}
},
choosePictures: function() {
window.imagePicker.getPictures(function(res){
alert(res+",success");
}, function(res){
alert(res+",failed");
}, {
maximumImagesCount: 10,
width: 80,
height: 80,
quality: 80
});
}
}
});调用服务
angular.module('starter.controllers', [])
.controller('MyCtrl', function($scope, $state, $ionicActionSheet, UploadFile,Toast, SelectPicture) {
$scope.avatar_src = "img/default_avatar.jpg";
$scope.selectAvatar = function(){
// 显示操作表
$ionicActionSheet.show({
buttons: [
{ text: '<p >拍照<p>' },
{ text: '<p >从相册选择<p>' },
],
buttonClicked: function(index) {
//设置头像
SelectPicture.chooseSinglePicture(index, 120, 120, $scope);
return true;
}
});
}
