Question

下午好，

我正在尝试使用POST方法在我的第一个iOS应用程序中上传图像，我正在尝试尝试但是有些东西是错的或者可能缺少某些内容我不确定但是我收到了消息“ 403 Forbidden “以及长文：

<!--
   - Unfortunately, Microsoft has added a clever new
   - "feature" to Internet Explorer. If the text of
   - an error's message is "too small", specifically
   - less than 512 bytes, Internet Explorer returns
   - its own error message. You can turn that off,
   - but it's pretty tricky to find switch called
   - "smart error messages". That means, of course,
   - that short error messages are censored by default.
   - IIS always returns error messages that are long
   - enough to make Internet Explorer happy. The
   - workaround is pretty simple: pad the error
   - message with a big comment like this to push it
   - over the five hundred and twelve bytes minimum.
   - Of course, that's exactly what you're reading
   - right now.
-->

而且我不确定我现在要做什么，因为我只是按照教程将图像上传到我的FTP。

我要从xcode发布我的代码：

            NSData *imageData = UIImageJPEGRepresentation(_imageView.image, 90);
            NSString *urlString = @"http://website.com/register.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=\"hello.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);

那是我的PHP文件：

<?php
$uploaddir = './imagenes/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
        echo "http://website.com/imagenes/{$file}";
}
?>

我需要做些什么来完成这项工作？ 我觉得我非常接近，但目前还没有工作......

提前致谢。
