我有一个rest-webservice，我想将图像上传为base64字符串并使用php在我的网络服务器上对其进行解码。
我的代码：
if (isset($para['picture']) or isset($para['filetype']) )
{
if (isset($para['picture']) and isset($para['filetype']))
{
if (!($para['filetype'] == 'jpg' || $para['filetype'] == 'png'))
{
$arr['Code'] = 617;
$arr['Message'] = $msg->getMessage(617);
$response->body = json_encode($arr);
return $response;
}
echo $para['picture'];
$bin = base64_decode(str_replace(' ', '+', $para['picture']));
if (strlen($bin) >(524288*2))
{
$arr['Code'] = 624;
$arr['Message'] = $msg->getMessage(624);
$response->body = json_encode($arr);
return $response;
}
$uid = $dbmodel->getUid($sid);
if($uid<1)
{
$arr['Code'] = 699;
$arr['Message'] = $msg->getMessage(699);
$response->body = json_encode($arr);
return $response;
}
$file = fopen($_SERVER['DOCUMENT_ROOT']."/img/".$uid.".".$para['filetype'], 'w');
fwrite($file, $bin);
fclose($file);
$dbmodel->insertPicture($uid,URL_ROOT."/img/".$uid.".".$para['filetype']);
}
else
{
$arr['Code'] = 616;
$arr['Message'] = $msg->getMessage(616);
$response->body = json_encode($arr);
return $response;
}
数据库模型：
function insertPicture($uid,$link)
{
$result = mysql_query("select link from USER_PICTURE where USER_ID=$uid");
if (mysql_num_rows($result)==1)
{
$row = mysql_fetch_array($result);
$row['link'];
$split = explode("/img/", $row['link']);
unlink($_SERVER['DOCUMENT_ROOT']."/img/".$split[1]);
}
$result = mysql_query("INSERT INTO USER_PICTURE (user_id,link) VALUES ($uid, '$link')ON DUPLICATE KEY UPDATE link='$link'");
if ($result)
{
return true;
}
return false;
}
我用以下方式调用我的网络服务：
