}app.api.x ：是封装的各类请求url地址
app.util.x ：是封装的函数，关于使用
1. 先util添加方法
2. app.js
3. 页面上调用，需要声明
后端php代码
<?php
class Imageadmin
{ public function imageupload()
{
//名字获取
$wxid=$_POST["num"];
//时间获取
$diaryTime=$_POST["datetime"];
//获取日期
$date = $_POST["date"];
$a = substr($_FILES['file']['type'],6);//获取图片后缀
//$a = strstr( $_FILES['file']['type'], '/');
$file_name=$date.'\\'.$diaryTime.'_'.$wxid.'.'.$a;//拼装存储地址path
$file_name1=$date.'/'.$diaryTime.'_'.$wxid.'.'.$a;//拼装图片浏览path
$path = "D:\www\File\\".$file_name;//存储path
$dir = iconv("UTF-8", "GBK","D:\www\File\\".$date);//判断文件夹是否存在
if (!file_exists($dir)){
mkdir ($dir,0777,true);//不存在 创建新文件夹
$panduan = move_uploaded_file($_FILES['file']['tmp_name'], $path);//存入图片
} else {
$panduan = move_uploaded_file($_FILES['file']['tmp_name'], $path);//存入已有文件夹内
}
//保存到指定路径 指定名字
if ($panduan){//存储成功
$res = ['errCode'=>0,'errMsg'=>'图片上传成功','file'=>$file_name1,'Success'=>true];
return json($res);
}else{//失败
$res = ['errCode'=>0,'errMsg'=>'图片上传失败','file'=>'https://127.0.0.1:80/xxxx.png','Success'=>!true];
return json($res);
}
} }
