無法使用PHP腳本從iPhone POST到Web服務器

Question

嗯，我對iPhone和PHP開發都很新，並且試圖簡單地將映像本地發佈到我的web服務器上（我已經設置了web服務器） 。由於某種原因，我的PHP腳本正在執行，儘管該文件沒有被保存。

我相信這是這裏最基本的問題，但我似乎不能找到問題。真的很感謝你們的幫助。謝謝！

我的Objective-C代碼：

UIImageView *imageView = [[UIImageView alloc] init]; 
imageView.image = [UIImage imageNamed:@"13.png"]; 

NSData *imageData = UIImageJPEGRepresentation(imageView.image, 90); 
NSString *urlString = @"http://localhost/uploader.php"; 
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init]; 
[request setTimeoutInterval:60.0]; 
[request setURL:[NSURL URLWithString:urlString]]; 
[request setHTTPMethod:@"POST"]; 

NSString *boundary = [NSString stringWithString:@"---------------------------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:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\";filename=\"myfile.jpg\"\r\n"] 
        dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:@"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]; 
NSLog(@"%@",[[NSString alloc] initWithData:[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil] encoding:NSUTF8StringEncoding]); 

我的PHP腳本：

<?php 
$target = "./upload/"; 
$target = $target.basename($_FILES['userfile']['name']) ; 
$check = getimagesize($_FILES['userfile']['tmp_name']); 

if (move_uploaded_file($_FILES['userfile']['tmp_name'], './upload/')) { 
    echo "YES"; 
} 
else 
    echo "NO"; 

?> 

這些都是在PHP打印這些變量的時候，我得到的值：

print_r($target); 

./upload/myfile.jpg 

print_r($check[0]); 

320 

print_r($_REQUEST); 

Array 
(
) 


print_r($_FILES[userfile]); 

Array 
(
    [name] => myfile.jpg 
    [type] => application/octet-stream 
    [tmp_name] => /private/var/tmp/phpWJE4UC 
    [error] => 0 
    [size] => 8829 
) 

print_r($_FILES[name]): 

(empty) 

print_r($_FILES[type]); 

(empty) 

print_r($_FILES[tmp_name]); 

(empty) 

print_r($_FILES[error]); 

(empty) 

print_r($_FILES[size]); 

(empty) 

print_r($_FILES); 


Array 
(
    [userfile] => Array 
     (
      [name] => myfile.jpg 
      [type] => application/octet-stream 
      [tmp_name] => /private/var/tmp/phpMvJ4oR 
      [error] => 0 
      [size] => 8829 
     ) 

)

你移動通話不正確。您必須爲目標指定一個文件名。你只提供了一個目錄，所以通話失敗。 PHP不會爲你創建一個文件名，你必須自己指定它。

if (move_uploaded_file($_FILES['userfile']['tmp_name'], './upload/name_of_file_to_write')) { 
                    ^^^^^^^^^^^^^^^^^^^^^
