将文件上传到 iPhone 上的 FTP 服务器 [英] Upload File to FTP Server on iPhone
问题描述
我想实现将文件上传到 FTP 服务器的逻辑.
I would like to implement logic that uploads file to FTP Server.
我是 iPhone 开发的新手,所以想找出首选方法.在浏览了此任务的可用 API 后,我设法只找到了使用 CFNetwork 的代码(看起来不是基于 Objective C).
I am new in iPhone development, so want to figure out preferred approach. After browsing available API for this task I have managed to find only code that uses CFNetwork (that looks like not Objective C based).
还有使用基于 Objective C 的 NSURL 等的 URL 加载系统.
There is also URL Loading System that uses NSURL etc which are Objective C based.
那么,我的问题是:是否可以使用 URL 加载系统来实现文件上传到 FTP 服务器?
So, my question: Is it possible to use URL Loading System to implement file upload to FTP Server?
谢谢.
推荐答案
我使用 PHP Page 将文件发布到并让 PHP 处理上传....
I use a PHP Page to post a file to and have PHP handle the uploading....
此代码用于上传照片,但它可以适用于任何文件.
This code is used to upload a photo, but it can be adapted to work with any file.
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:@"
--%@
",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Content-Disposition: form-data; name="userfile"; filename="%@"
",filename]] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream
"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"
--%@--
",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];
