iPhone/Cocoa在Ubuntu（LAMP）上將圖像文件上傳到PHP

我想從我的iPhone應用上傳一個小的.png文件（50x50像素）到我的Ubuntu服務器。我已經嘗試了幾種方法來解決在StackOverflow和網絡上其他地方發佈的問題，但還沒有成功。我已經發布了我的Obj-C代碼來上傳文件並記錄服務器響應，我的PHP代碼在服務器上，以及我得到的響應。我真的很感謝一些幫助解決這個問題 - 請讓我知道，如果你看到我的代碼的任何問題 - 謝謝！iPhone/Cocoa在Ubuntu（LAMP）上將圖像文件上傳到PHP

的OBJ-C代碼：

// This method uploads the image to the server 
-(void)uploadImage{ 

    NSURL *url = [NSURL URLWithString:@"http://mydomain.com/upload.php"]; 

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; 

    [request setUseKeychainPersistence:YES]; 

    NSString *fileName = [NSString stringWithFormat:@"%@",self.avatarFileName]; 
    [request addPostValue:fileName forKey:@"name"]; 

    // Upload an image 
    NSData *imageData = UIImagePNGRepresentation([UIImage imageNamed:self.avatarFileName]); 

    // Make sure it's not null.. 
    NSLog(@"%d",[imageData length]); 

    // Set the data and filename 
    [request setData:imageData withFileName:fileName andContentType:@"image/png" forKey:@"userfile"]; 

    [request setDelegate:self]; 
    [request setDidFinishSelector:@selector(uploadRequestFinished:)]; 
    [request setDidFailSelector:@selector(uploadRequestFailed:)]; 

    [request startAsynchronous]; 
} 

- (void)uploadRequestFinished:(ASIHTTPRequest *)request{  
    NSString *responseString = [request responseString]; 
    NSLog(@"Upload response %@", responseString); 
} 

- (void)uploadRequestFailed:(ASIHTTPRequest *)request{ 

    NSLog(@" Error - Statistics file upload failed: \"%@\"",[[request error] localizedDescription]); 
}

Ubuntu服務器上的PHP代碼：從服務器

<?php 
echo ' -- Hit Script --'; 
print_r($_FILES); 
$target_path = "files/"; 
$target_path = $target_path . basename($_FILES['uploadedfile']['name']); 
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { echo "The file ". basename($_FILES['uploadedfile']['name']). " has been uploaded"; } else{ echo "There w 
as an error uploading the file, please try again!"; } 
?>

響應：

Upload response -- Hit Script -- 
Array 
(
) 
There was an error uploading the file, please try again!

我想你使用的密鑰userfile的用於上載文件，而不是上傳文件（使用$ _FILES ['userfile']）。
