將圖像從iOS上傳到PHP

我一直在將UIImage上傳到網絡服務器。問題是，圖像從不出現在服務器上。來自HTML文件的普通POST可以工作。我認爲這是我的Objective-C代碼中的一個問題。將圖像從iOS上傳到PHP

這裏是我的Objective-C代碼：

NSData *imageData = UIImagePNGRepresentation(delegate.dataBean.image); 
NSString *urlString = [NSString stringWithFormat:@"%@test.php", delegate.dataBean.hosterURL]; 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
[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:@"rn--%@rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.png\"rn"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-streamrnrn"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[NSData dataWithData:imageData]]; 
[body appendData:[[NSString stringWithFormat:@"rn--%@--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[request setHTTPBody:body]; 

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 

NSLog([NSString stringWithFormat:@"Image Return String: %@", returnString]);

這是我的PHP代碼：

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

echo "file=".$file; //is empty, but shouldn't 

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $uploadfile)) { 
    echo $file; 
} 
else { 
    echo "error"; 
} 
?>

的print_r（$ _ FILES）又有什麼節目 – 2012-07-10 13:01:20

它顯示一個空數組：陣列（） – 2012-07-10 13:05:34

$ _FILES應該被默認定義。但是如果有上傳，它不應該是空的。 – 2012-07-10 13:13:39

現在我已經通過我自己解決它=）

我忘了反斜槓在身體裏。

這裏是機身右側：

NSMutableData *body = [NSMutableData data]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.png\"\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];
