php后台接受上传图片
配合上个博文的,捣鼓了一个php后台的东西,虽然不怎么懂,但慢慢来,还是可以的。传送门
java太不好学了,玩玩php,满足一下自己。
那个图片压缩的效果很明显,居然压缩了好几倍。
<?php header('Content-type:text/html; charset="utf-8"'); $base64_image_content=$_POST["file"]; //var_dump($$base64_image_content); if(preg_match('/^(data:\s*image\/(\w+);base64,)/i',$base64_image_content,$result)){ $type=$result[2]; $new_file="upload/".date("Ymd",time())."/"; if(!file_exists($new_file)){ /*权限问题,0777是最好的,其他可能会被禁止*/ mkdir($new_file,0777); echo "创建成功"; }else{ echo "创建失败"; } $new_file=$new_file.time().".{$type}"; if(file_put_contents($new_file,base64_decode(str_replace($result[1],"",$base64_image_content)))){ echo "成功"; }else{ echo "失败"; } }else{ echo "不匹配!!"; } ?>
表单提交,传送图片
<?php header('Content-type:text/html; charset="utf-8"'); $upload_dir = 'uploads/'; if(strtolower($_SERVER['REQUEST_METHOD']) != 'post'){ exit_status(array('code'=>1,'msg'=>'错误提交方式')); } if(array_key_exists('file',$_FILES) && $_FILES['file']['error'] == 0 ){ $pic = $_FILES['file']; if(move_uploaded_file($pic['tmp_name'], $upload_dir.$pic['name'])){ exit_status(array('code'=>0,'msg'=>'上传成功','url'=>$upload_dir.$pic['name'])); } } echo $_FILES['file']['error']; exit_status(array('code'=>1,'msg'=>'出现了一些错误')); function exit_status($str){ echo json_encode($str); exit; } ?>
