iPhone FTPS客户端

问题描述

我不知道如何在iPhone上制作FTPS（FTP over SSL）。我想使用下面的代码：

  ftpStream = CFWriteStreamCreateWithFTPURL（NULL，（CFURLRef）url）; 
 CFWriteStreamSetProperty（ftpStream，kCFStreamPropertyFTPUserName，username）; 
 CFWriteStreamSetProperty（ftpStream，kCFStreamPropertyFTPPassword，password）; 
 
 self.networkStream =（NSOutputStream *）ftpStream; 
 [self.networkStream setProperty：NSStreamSocketSecurityLevelSSLv3 forKey：（id）NSStreamSocketSecurityLevelKey]; 
 
 self.networkStream.delegate = self; 
 [self.networkStream scheduleInRunLoop：[NSRunLoop currentRunLoop] forMode：NSDefaultRunLoopMode]; 
 [self.networkStream open]; 
 
 
 $ b  - （void）stream：（NSStream *）aStream handleEvent：（NSStreamEvent）eventCode 
 {
 NSLog（@Hello \\\
）; 
} 
  

这段代码连接到服务器，但不会一起说话。我也尝试使用以下来设置安全级别：

pre $ NS $ Dictionary $ {NSDictionary dictionaryWithObjectsAndKeys：
（NSString *）kCFStreamSocketSecurityLevelSSLv3，kCFStreamSSLLevel，
kCFBooleanTrue，kCFStreamSSLAllowsAnyRoot，
kCFBooleanFalse，kCFStreamSSLValidatesCertificateChain，
主机名，kCFStreamSSLPeerName，
kCFBooleanFalse，kCFStreamSSLIsServer，
kCFBooleanFalse，kCFStreamSSLValidatesCertificateChain，
kCFBooleanTrue，kCFStreamSSLAllowsExpiredCertificates，
kCFBooleanTrue，kCFStreamSSLAllowsExpiredRoots，
nil];
CFWriteStreamSetProperty（ftpStream，kCFStreamPropertySSLSettings，settings）;

这允许我连接和传输数据，但不通过SSL。

任何想法我做错了。

解决方案

iPhone上没有内置的FTPS功能，请参阅：

您必须建立自己的FTPS库。我也不知道iPhone上有任何第三方FTPS库 - 但上面的文章给出了一些概述&策略传输文件的可能性有多大。

I have no clue how to make an FTPS (FTP over SSL) on the iPhone. I would like to use the following code

ftpStream = CFWriteStreamCreateWithFTPURL(NULL, (CFURLRef) url);
CFWriteStreamSetProperty(ftpStream, kCFStreamPropertyFTPUserName,username);
CFWriteStreamSetProperty(ftpStream, kCFStreamPropertyFTPPassword,password);

self.networkStream = (NSOutputStream *) ftpStream;
[self.networkStream setProperty:NSStreamSocketSecurityLevelSSLv3 forKey:(id)NSStreamSocketSecurityLevelKey];

self.networkStream.delegate = self;
[self.networkStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[self.networkStream open];

...

- (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode
{
  NSLog(@"Hello\n");
}

This code connects to the server but then stops talking all together. I have also tried using the following to set the security level

NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
    (NSString *)kCFStreamSocketSecurityLevelSSLv3, kCFStreamSSLLevel,
    kCFBooleanTrue, kCFStreamSSLAllowsAnyRoot,
    kCFBooleanFalse, kCFStreamSSLValidatesCertificateChain,
    hostName, kCFStreamSSLPeerName,
    kCFBooleanFalse, kCFStreamSSLIsServer,
    kCFBooleanFalse,kCFStreamSSLValidatesCertificateChain,
    kCFBooleanTrue, kCFStreamSSLAllowsExpiredCertificates,
    kCFBooleanTrue, kCFStreamSSLAllowsExpiredRoots,
    nil];
CFWriteStreamSetProperty(ftpStream, kCFStreamPropertySSLSettings, settings);

This allows me to connect and transfer data but not through SSL.

Any idea what I am doing wrong.

解决方案

There are no built-in FTPS capabilities on the iPhone see: http://developer.apple.com/iphone/library/technotes/tn2009/tn2152.html

You have to build your own FTPS library. I'm also not aware of any third-party FTPS library for the iPhone - but the article above gives some overview & strategies what possibilities for transferring files are available.
