Question

我正在制作一个我需要上传视频和音频的应用程序，我听过很多关于mediapicker但我实际上并没有得到如何处理它。谁能告诉我这件事。

NSString * urlString = [NSString stringWithFormat：@“http://www.example.com/uploadvideoxml.php?user_id=%@”，[vedioDict valueForKey：@“user_id”]];

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:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

[body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.mov\"\r\n",valuestr]] dataUsingEncoding:NSUTF8StringEncoding]];

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

[body appendData:[NSData dataWithData:[vedioDict valueForKey:@"VideoUrl"]]];

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

[request setHTTPBody:body];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:returnData]; 

[xmlParser setDelegate:self];

[xmlParser parse];

Hi,

通过使用此代码，您可以将任何音频文件发送到服务器...按照这个简单的步骤.. 当您想要将图像发送到服务器时，此步骤也适用

NSString *postData = [NSString stringWithFormat:@"Your XML goes here";

titleForSegmentAtIndex：self.participantSegmentCtrl.selectedSegmentIndex]，ratingStar，[NSString stringWithFormat：@“％d”，adviceTypeSegmentCtrl.selectedSegmentIndex]，USER_CREDENTIALS]; NSLog（@“本地音频上传...％@”，postData）; NSMutableURLRequest * request = [[[NSMutableURLRequest alloc] init] autorelease];

NSString * urlString = [SERVER_IP stringByAppendingString：@“getAudioadvise_ipad.php”]; NSData * audioData = [[NSData alloc] initWithContentsOfFile：fileName]; // if（[audioData length]＆lt; = 0） // return;

request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL：[NSURL URLWithString：urlString]]; [请求setHTTPMethod：@“POST”];

NSString * boundary = @“--------------------------- 14737809831466499882746641449”;

NSString * contentType = [NSString stringWithFormat：@“multipart / form-data; boundary =％@”，boundary];

[请求addValue：contentType forHTTPHeaderField：@“Content-Type”];

NSMutableData * postbody = [NSMutableData data];

//参数1 [postbody appendData：[[NSString stringWithFormat：@“\ r \ n - ％@ \ r \ n”，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; [postbody appendData：[[NSString stringWithFormat：@“Content-Disposition：form-data; name = \”postData \“\ r \ n \ r \ n \ n％n”@，postData] dataUsingEncoding：NSUTF8StringEncoding]]; [postbody appendData：[[NSString stringWithFormat：@“\ r \ n - ％@ \ r \ n”，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; //标签

[postbody appendData：[[NSString stringWithFormat：@“\ r \ n - ％@ \ r \ n”，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; [postbody appendData：[[NSString stringWithFormat：@“Content-Disposition：form-data; name = \”userfile \“; filename = \”％@。wav \“\ r \ n”，[schedule_Obj.ID objectAtIndex：[ schedule_Obj.recordIndex intValue]]] dataUsingEncoding：NSUTF8StringEncoding]]; [postbody appendData：[[NSString stringWithString：@“Content-Type：application / octet-stream \ r \ n \ r \ n”] dataUsingEncoding：NSUTF8StringEncoding]]; [postbody appendData：[NSData dataWithData：audioData]]; //在这里添加音频数据 [postbody appendData：[[NSString stringWithFormat：@“\ r \ n - ％ - - \ r \ n”，boundary] dataUsingEncoding：NSUTF8StringEncoding]];

[request setHTTPBody：postbody]; NSData * returnData = [NSURLConnection sendSynchronousRequest：request returningResponse：nil error：nil]; returnString = [[NSString alloc] initWithData：returnData encoding：NSUTF8StringEncoding]; [audioData发布];
