我正在尝试向PHP服务器发送值，但总是，我得到HTTP REsponse 200并且在我的服务器中我没有得到我发送的值，不知道接下来的问题是我的Android和PHP的代码片段，可以任何人都帮我这个？...对不起代码......我也跟着这个Android file upload - $_FILES returns empty
PHP方面我使用了smarty framework
$print = false;
$header = true;
if(isset($_REQUEST['action']) && $_REQUEST['action'] =='imagetest')
{
$error = '0';
$val = basename($_FILES['image']['name']);
if($val != '')
{
$error = '1';
$msg = 'Image Not Upload Please Try Agin';
$param = array("status"=>"error","msg"=>$val);
$val = json_encode($param);
echo $val;
exit;
}
/*if($_FILES['image'] == '')
{
$error = '1';
$msg = 'Image Not Upload Please Try Agin';
$param = array("status"=>"error","msg"=>$msg);
$val = json_encode($param);
echo $val;
exit;
}*/
if($error == '0')
{
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['image']['name']);
if(move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
$msg = 'Image inserted successfully';
$param = array("status"=>"success","msg"=>$msg);
$val = json_encode($param);
echo $val;
exit;
} else{
$msg = 'Image not inserted successfully';
$param = array("status"=>"success","msg"=>$msg);
$val = json_encode($param);
echo $val;
exit;
}
}
}
else
{
$msg = 'something went wrong';
$param = array("status"=>"success","msg"=>$msg);
$val = json_encode($param);
echo $val;
exit;

你可以参考这个很好的教程＆＃34; Android Uploading Camera Image, Video to Server with Progress Bar＆＃34;
答案 1 :(得分：0)
尝试在标题中指定文件的长度。如果没有Content-Length标头，似乎某些服务器可能会拒绝该文件。 E.g：
conn.setRequestProperty("Content-Length", Integer.toString(fileInputStream.available()));
