后台接收并处理图片代码
<?php
//print_r($_POST);
$base_img=$_POST['dataURL'];
// $base_img是获取到前端传递的值
$base_img = str_replace('data:image/jpeg;base64,', '', $base_img);
// 设置文件路径和命名文件名称
$path = "./";
$output_file = time().rand(100,999).'.jpeg';
$path = $path.$output_file;
// 创建将数据流文件写入我们创建的文件内容中
file_put_contents($path, base64_decode($base_img));
// 输出文件
print_r($output_file);
