由于项目需要,做了一个验证程序,将android手机上的图片或文件通过POST方式提交到Linux服务器,服务端为PHP.
PHP 服务器源码
<? function upload_image() { $db =$this ->loadDB(); $db->Execute("SET NAMES UTF8"); if($_FILES) { foreach($_FILES as $v){ $extendname = explode( ".",$v[name]); $file_name=$v[name]; $code=$extendname[0]; $exten=$db->GetOne("..."); //文件保存目录 $temp_dir="order_images".date("/Y/m/d/",time()).$exten; //创建文件 $this->mkdirs($temp_dir); //保存图片 if(copy($v[tmp_name], $temp_dir."/".$v[name])) { //.......... }else { echo "f"; } } } } ?>
