ios如何通过FTP上传文件？

Question

我想在FTP服务器上上传文件。如何实现这个功能。

我尝试过许多库，例如 raccoons、SimpleFTPSample，但这些库已弃用的代码无法正常工作。

NSURL *url_upload = [NSURL URLWithString:@"ftp://username:password!@host:port/filename.wav"];
        NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url_upload];
        [request setHTTPMethod:@"PUT"];
        NSString *file = [[NSBundle mainBundle] pathForResource:@"1kb" ofType:@"png"];
        NSURL *docsDirURL = [NSURL fileURLWithPath:filePath];

    NSURLProtectionSpace * protectionSpace = [[NSURLProtectionSpace alloc] initWithHost:url_upload.host port:[url_upload.port integerValue] protocol:url_upload.scheme realm:nil authenticationMethod:nil];

    NSURLCredential *cred = [NSURLCredential
                             credentialWithUser:@"username"
                             password:@"pass!"
                             persistence:NSURLCredentialPersistenceForSession];


    NSURLCredentialStorage * cred_storage ;
    [cred_storage setCredential:cred forProtectionSpace:protectionSpace];
    NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration defaultSessionConfiguration];
    sessionConfig.URLCredentialStorage = cred_storage;


    NSURLSession *upLoadSession = [NSURLSession sessionWithConfiguration:sessionConfig delegate:self delegateQueue:nil];

    NSURLSessionUploadTask *uploadTask = [upLoadSession uploadTaskWithRequest:request fromFile:docsDirURL completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        if (error != NULL)
        {
            NSLog(@"%@", error.localizedDescription);
        }
        else{

        }
    }];

    [uploadTask resume];

请建议我一些 swift 或 Objective C 实现来将文件上传到 FTP 服务器上。

您可以使用

https://github.com/amosavian/FileProvider

let returnCredential = URLCredential(user:<username>, password:<password>, persistence: .none)

let ftpFileProvider = FTPFileProvider(baseURL: URL(string:<host eg ftp:>, mode: .default, credential: returnCredential, cache: .none)!
ftpFileProvider.copyItem(localFile: <local_file_path>, to:<where on ftp>, completionHandler: { error in         
   if error != nil {
      print(error)
      return
   }
})
