我想实现将文件上传到FTP服务器的逻辑。
我是iPhone开发的新手,所以想要找出首选的方法。浏览此任务的可用API后,我设法只找到使用CFNetwork的代码(看起来不像Objective C)。
还有使用NSURL等的URL加载系统,它们是基于目标C的。
所以,我的问题是:是否可以使用URL加载系统实现文件上传到FTP服务器?
感谢。

我使用PHP页面发布文件并让PHP处理上传....
此代码用于上传照片,但可以调整以适用于任何文件。
PHP代码:
<?php
$uploaddir = 'photos/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
echo "OK";
} else {
echo "ERROR";
}
?>
iPhone代码:
- (BOOL)uploadImage:(NSData *)imageData filename:(NSString *)filename{
NSString *urlString = @"http://www.yourdomainName.com/yourPHPPage.php";
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[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:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n",filename]] 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];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding] autorelease];
return ([returnString isEqualToString:@"OK"]);
}
方法调用:
[self uploadImage:UIImageJPEGRepresentation(imageView.image, 1.0) filename:imageName];
