发送AVAudioRecorder到服务器iOS

我试图在过去的几天上传一个本地保存的soundelogging到一个服务器（它用php文件把它保存到服务器）。 问题是我找不到一个方法来做到这一点。

在录制声音（AVAudioRecorder）时，它保存在“NSTemporaryDirectory（）”中： 

NSURL *temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]];

现在，我查到的答案是使用ASIHTTPRequest 。 但问题是，它不支持在iOS 6。

还有一些其他的库，但不pipe什么和我怎么尝试都没有什么作用。 如果有人能帮助我，我会喜欢它…

这是我的代码：

ViewController.h 

 #import <UIKit/UIKit.h> #import <AVFoundation/AVFoundation.h> #import <CoreAudio/CoreAudioTypes.h> @interface ViewController : UIViewController <AVAudioRecorderDelegate,AVAudioPlayerDelegate> { UIButton *recordButton; UIButton *playButton; UIButton *uploadFile; UILabel *recStateLabel; BOOL isNotRecording; NSURL *temporaryRecFile; AVAudioRecorder *recorder; AVAudioPlayer *player; } @property (nonatomic,retain) IBOutlet UIButton *uploadFile; @property (nonatomic,retain) IBOutlet UIButton *playButton; @property (nonatomic,retain) IBOutlet UIButton *recordButton; @property (nonatomic,retain) IBOutlet UILabel *recStateLabel; -(IBAction)recording; -(IBAction)playback; -(IBAction)upload; @end

ViewController.m 

 #import "ViewController.h" #import <AVFoundation/AVFoundation.h> #import "STHTTPRequest.h" @interface ViewController () @end @implementation ViewController @synthesize recordButton,playButton,uploadFile,recStateLabel; -(IBAction)recording { if(isNotRecording) { isNotRecording = NO; [recordButton setTitle:@"Stop" forState:UIControlStateNormal]; playButton.hidden = YES; recStateLabel.text = @"Recording"; temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]]; NSDictionary *recordSettings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:AVAudioQualityMin], AVEncoderAudioQualityKey, [NSNumber numberWithInt:16], AVEncoderBitRateKey, [NSNumber numberWithInt: 2], AVNumberOfChannelsKey, [NSNumber numberWithFloat:44100.0], AVSampleRateKey, nil];

// Dispose of any resources that can be recreated. } @end

ViewController.m包含一些我使用STHTTPRequest和AFNetworking等库的testing

这行代码对我很好

现在我已经发布了我的整个代码logging，保存，播放和发布到服务器

我希望它会适用于你

使用AFNetworking一切工作的一些变化：

  • 使用appendPartWithFileURL:name:fileName:mimeType:error:避免必须将歌曲数据加载到内存中。
  • 正如@glenwayguy所build议的那样，使用singleton模式来保持对AFHTTPClient的静态引用。 否则，您有可能过早地释放操作。
  • 您应该使用AFHTTPClient -HTTPRequestOperationWithRequest:success:failure:来debugging服务器响应。 你提到你的上传进度块没有被触发。 这可能是您的服务器正在返回500,400或404错误。 
  - (void)uploadAudio:(NSString *)audioPath jobId:(NSString *)jobIdStr{ FMResultSet *results = [database executeQuery:@"select * from AUDIOS where AUDIOLOC = ? and areqsync = 0 ",audioPath]; if(![results next]) { NSLog(@"Audio already uploaded"); } else{ NSLog(@"Audio is to be uploaded"); NSURL *audiourl=[NSURL URLWithString:audioPath]; NSLog(@"audio url and path are %@ --- %@",audiourl,audioPath); NSData *audioData=[NSData dataWithContentsOfFile:audiourl.path]; @try { NSLog(@"In upload audio function"); NSString *strURL = @"http://abc.com/data/default.aspx"; ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:strURL]]; request= [request initWithURL:[NSURL URLWithString:strURL]]; [request setShouldContinueWhenAppEntersBackground:YES]; [request setShouldAttemptPersistentConnection:YES]; [request setPostValue:jobIdStr forKey:@"lbljid"]; [request setPostValue:@"2" forKey:@"lblMtype"]; [request setPostValue:[Settings UserName] forKey:@"lblUsername"]; [request setPostValue:[Settings Password] forKey:@"lblpassword"]; [request addData:audioData withFileName:@"audio.caf" andContentType:@"audio/x-caf" forKey:@"filMyFile"]; [request setCompletionBlock:^{ BOOL success = [database executeUpdate:@"UPDATE AUDIOS SET areqsync = '1' WHERE AUDIOLOC = ?",audioPath ]; NSLog(success ? @"Audio Update to syncronised Yes" : @"Update to ended No"); [self requestFinished:request]; }]; //if request failed [request setFailedBlock:^{ [self requestFailed:request]; NSLog(@"request Failed: %@",[request error]); }]; [request startAsynchronous]; uploadCount++; } @catch (NSException *exception) { NSLog(@"Exception name and reson is %@ ------- %@",exception.name, exception.reason); } @finally { NSLog(@"finalyy of upload audio"); } }//end of if audio already sync }

这个代码的主要问题可能是它在当前的尝试（在使用AFNetworking的时候，在试图分配NSData* songData的注释掉的代码中）是方法upload的代码行应该从： 

  NSData *data = [NSData dataWithContentsOfFile:NSTemporaryDirectory()];

对此： 

  NSData *data = [NSData dataWithContentsOfFile:temporaryRecFile];
