如何在iPhone應用程序中將音頻文件上傳到服務器？

Question

NSString *urlString1 = @"http://www.php.eminosoft.com/123singles/upload.php";

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString1]];
[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 stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"song.mp3\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

[body appendData:[[NSString stringWithString:@"Content-Type:application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

[body appendData:[NSString stringWithString:secondString]];

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];    

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"username\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"demo"] dataUsingEncoding:NSUTF8StringEncoding]]; 


[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];    

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"type\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"5"] dataUsingEncoding:NSUTF8StringEncoding]]; 


[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];

我得到的答復是：

“文件上傳成功”

但問題是文件內容大小以字節為單位，音頻文件不支持播放。

請幫助我，如何將音頻文件上傳到服務器？

Answer 1

您可以嘗試使用FTP發送音頻文件，因為音頻文件很大，因此需要很長時間才能在服務器上上傳。 FTP縮短了該時間段。 希望能有所幫助。

Answer 2

我正在使用ASIHTTPRequest上傳如下所示的音頻文件，

NSURL *audiourl = [NSURL URLWithString:@"Your Url"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:audiourl];
NSData *postData = [NSData dataWithContentsOfURL:SoundPath];
//SoundPath is your audio url path of NSDocumentDirectory.
[request addData:postData withFileName:@"myAudio.caf" andContentType:@"audio/caf" forKey:@"company_audio"];
[request setDelegate:self];
[request startSynchronous];

這樣，您可以輕松地在服務器上上傳音頻文件。
