iOS上传视频到服务器题

iOS上传视频到服务器

这里介绍用AFN上传本地拍摄的视频到服务端

//视频转换为MP4

//转码操作...

_hud.mode = MBProgressHUDModeIndeterminate;

_hud.labelText = @"转码中...";

AVURLAsset *avAsset = [AVURLAsset URLAssetWithURL:_filePathURL  options:nil];

NSDateFormatter* formater = [[NSDateFormatter alloc] init];

[formater setDateFormat:@"yyyyMMddHHmmss"];

_fileName = [NSString stringWithFormat:@"output-%@.mp4",[formater stringFromDate:[NSDate date]]];

_outfilePath = [NSHomeDirectory() stringByAppendingFormat:@"/Documents/%@", _fileName];

NSArray *compatiblePresets = [AVAssetExportSession exportPresetsCompatibleWithAsset:avAsset];

if ([compatiblePresets containsObject:AVAssetExportPresetMediumQuality])

{

MyLog(@"outPath = %@",_outfilePath);

AVAssetExportSession *exportSession = [[AVAssetExportSession alloc]initWithAsset:avAsset presetName:AVAssetExportPresetMediumQuality];

exportSession.outputURL = [NSURL fileURLWithPath:_outfilePath];

exportSession.outputFileType = AVFileTypeMPEG4;

[exportSession exportAsynchronouslyWithCompletionHandler:^{

if ([exportSession status] == AVAssetExportSessionStatusCompleted) {

MyLog(@"AVAssetExportSessionStatusCompleted---转换成功");

_filePath = _outfilePath;

_filePathURL = [NSURL URLWithString:[NSString stringWithFormat:@"file://%@",_outfilePath]];

MyLog(@"转换完成_filePath = %@\n_filePathURL = %@",_filePath,_filePathURL);

//获取大小和长度

[self SetViewText];

[self uploadNetWorkWithParam:@{@"contenttype":@"application/octet-stream",@"discription":description}];

}else{

MyLog(@"转换失败,值为:%li,可能的原因:%@",(long)[exportSession status],[[exportSession error] localizedDescription]);

[_hud hide:YES];

[MyHelper showAlertWith:nil txt:@"转换失败,请重试"];

}

}];

}

#pragma mark - 开始上传

-(void)uploadNetWorkWithParam:(NSDictionary*)dict

{

MyLog(@"开始上传_filePath = %@\n_filePathURL = %@",_filePath,_filePathURL);

AFHTTPRequestSerializer *ser=[[AFHTTPRequestSerializer alloc]init];

NSMutableURLRequest *request =

[ser multipartFormRequestWithMethod:@"POST"

}

} error:nil];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSProgress *progress = nil;

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {

if (error) {

MyLog(@"request = %@", request );

MyLog(@"response = %@", response );

MyLog(@"Error: %@", error );

[_hud hide:YES];

CXAlertView *alert=[[CXAlertView alloc]initWithTitle:NSLocalizedString(@"Warning", nil)

message:NSLocalizedString(@"Upload Failed",nil)

cancelButtonTitle:NSLocalizedString(@"Iknow", nil)];

alert.showBlurBackground = NO;

[alert show];

} else {

MyLog(@"%@ %@", response, responseObject);

NSDictionary *backDict=(NSDictionary *)responseObject;

if ([backDict[@"success"] boolValue] != NO) {

_hud.labelText = NSLocalizedString(@"Updating", nil);

[self UpdateResxDateWithDict:backDict discription:dict[@"discription"]];

[_hud hide:YES];

}else{

[_hud hide:YES];

[MyHelper showAlertWith:nil txt:backDict[@"msg"]];

}

}

[progress removeObserver:self

forKeyPath:@"fractionCompleted"

context:NULL];

}];

[progress addObserver:self

forKeyPath:@"fractionCompleted"

options:NSKeyValueObservingOptionNew

context:NULL];

[progress setUserInfoObject:@"someThing" forKey:@"Y.X."];

[uploadTask resume];

}

记得上传成功之后要删除沙盒中的视频文件哦！代码奉上

#pragma mark - 清除documents中的视频文件

-(void)ClearMovieFromDoucments{

NSFileManager *fileManager = [NSFileManager defaultManager];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSArray *contents = [fileManager contentsOfDirectoryAtPath:documentsDirectory error:NULL];

NSEnumerator *e = [contents objectEnumerator];

NSString *filename;

while ((filename = [e nextObject])) {

MyLog(@"%@",filename);

if ([filename isEqualToString:@"tmp.PNG"]) {

MyLog(@"删除%@",filename);

[fileManager removeItemAtPath:[documentsDirectory stringByAppendingPathComponent:filename] error:NULL];

continue;

}

if ([[[filename pathExtension] lowercaseString] isEqualToString:@"mp4"]||

[[[filename pathExtension] lowercaseString] isEqualToString:@"mov"]||

[[[filename pathExtension] lowercaseString] isEqualToString:@"png"]) {

MyLog(@"删除%@",filename);

[fileManager removeItemAtPath:[documentsDirectory stringByAppendingPathComponent:filename] error:NULL];

}

}

}

好，整体思路已经清楚，拿到视频资源，先转为mp4，写进沙盒，然后上传，上传成功后要记得删除沙盒中的文件。
