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";
}
}
}
}
