将照片从iOS应用程序上传到我的网络服务器时出错。

我想知道是否有人知道问题出在哪里，以及如何解决问题。任何帮助将不胜感激。

以下是错误消息：

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>500 Internal Server Error</title>

<h1>Internal Server Error</h1>
<p>The server encountered an internal error or

以下是iOS代码：

- (IBAction)uploadPhoto:(id)sender {
    NSData *imageData = UIImageJPEGRepresentation(_imageView.image, 90);
    NSString *urlString = @"http://website.ca/uploadPhoto.php";

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    NSString *boundary = @"---------------------------14737809831466499882746641449";
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

    NSMutableData *body = [NSMutableData data];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\".jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imageData]];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [request setHTTPBody:body];

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
    NSLog(@"%@", returnString);
}

这是PHP代码：

<?php
$uploaddir = 'uploads/';
$ran = rand () ;

$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir .$ran.$file;

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
        echo "Uploaded";
}
?>

图片收到$ _POST [＆＃39; userfile＆＃39;]而不是$ _Files [＆＃39; userfile＆＃39;] ...使用以下代码

 <?php


$image = $_POST['userfile'];
$image = str_replace("<","",$image);
$image = str_replace(">","",$image);
$image = str_replace(" ","",$image);
$image = pack("H*", $image);
$filename = "img/image.png";
$f = fopen($filename,'wb');
fwrite($f, $image);
fclose($f);



?>
