iOS 使用AFN上传视频到服务器示例代码
这里介绍用AFN上传本地拍摄的视频到服务端。
整体思路：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。
压缩导出视频
//视频转换为MP4
//转码操作...
_hud.mode=MBProgressHUDModeIndeterminate;
_hud.labelText=@"转码中...";
AVURLAsset*avAsset=[AVURLAssetURLAssetWithURL:_filePathURLoptions:nil];
NSDateFormatter*formater=[[NSDateFormatteralloc]init];
[formatersetDateFormat:@"yyyyMMddHHmmss"];
_fileName=[NSStringstringWithFormat:@"output-%@.mp4",[formaterstringFromDate:[NSDatedate]]];
_outfilePath=[NSHomeDirectory()stringByAppendingFormat:@"/Documents/%@",_fileName];
NSArray*compatiblePresets=[AVAssetExportSessionexportPresetsCompatibleWithAsset:avAsset];
if([compatiblePresetscontainsObject:AVAssetExportPresetMediumQuality]){
MyLog(@"outPath=%@",_outfilePath);
AVAssetExportSession*exportSession=[[AVAssetExportSessionalloc]initWithAsset:avAssetpresetName:AVAssetExportPresetMediumQuality];
exportSession.outputURL=[NSURLfileURLWithPath:_outfilePath];
exportSession.outputFileType=AVFileTypeMPEG4;
[exportSessionexportAsynchronouslyWithCompletionHandler:^{
if([exportSessionstatus]==AVAssetExportSessionStatusCompleted){
MyLog(@"AVAssetExportSessionStatusCompleted---转换成功");
_filePath=_outfilePath;
_filePathURL=[NSURLURLWithString:[NSStringstringWithFormat:@"file://%@",_outfilePath]];
MyLog(@"转换完成_filePath=%@\\n_filePathURL=%@",_filePath,_filePathURL);
//获取大小和长度
[selfSetViewText];
[selfuploadNetWorkWithParam:@{@"contenttype":@"application/octet-stream",@"discription":description}];
}else{
MyLog(@"转换失败,值为:%li,可能的原因:%@",(long)[exportSessionstatus],[[exportSessionerror]localizedDescription]);
[_hudhide:YES];
[MyHelpershowAlertWith:niltxt:@"转换失败,请重试"];
}
}];
}
开始上传
-(void)uploadNetWorkWithParam:(NSDictionary*)dict{
MyLog(@"开始上传_filePath=%@\\n_filePathURL=%@",_filePath,_filePathURL);
AFHTTPRequestSerializer*ser=[[AFHTTPRequestSerializeralloc]init];
NSMutableURLRequest*request=
[sermultipartFormRequestWithMethod:@"POST"
URLString:[NSStringstringWithFormat:@"%@%@",kBaseUrl,kVideoUploadUrl]
parameters:@{@"path":@"show",@"key":_key,@"discription":dict[@"discription"],@"isimage":@(_isImage)}
constructingBodyWithBlock:^(idformData){
[formDataappendPartWithFileURL:_filePathURLname:@"file"fileName:_fileNamemimeType:dict[@"contenttype"]error:nil];
if(!_isImage){
[formDataappendPartWithFileURL:_path2Urlname:@"tmp"fileName:@"tmp.PNG"mimeType:@"image/png"error:nil];
}
}error:nil];
//@"image/png"@"application/octet-stream"mimeType
AFURLSessionManager*manager=[[AFURLSessionManageralloc]initWithSessionConfiguration:[NSURLSessionConfigurationdefaultSessionConfiguration]];
NSProgress*progress=nil;
NSURLSessionUploadTask*uploadTask=[manageruploadTaskWithStreamedRequest:requestprogress:&progresscompletionHandler:^(NSURLResponse*response,idresponseObject,NSError*error){
if(error){
MyLog(@"request=%@",request);
MyLog(@"response=%@",response);
MyLog(@"Error:%@",error);
[_hudhide:YES];
CXAlertView*alert=[[CXAlertViewalloc]initWithTitle:NSLocalizedString(@"Warning",nil)
message:NSLocalizedString(@"UploadFailed",nil)
cancelButtonTitle:NSLocalizedString(@"Iknow",nil)];
alert.showBlurBackground=NO;
[alertshow];
}else{
MyLog(@"%@%@",response,responseObject);
NSDictionary*backDict=(NSDictionary*)responseObject;
if([backDict[@"success"]boolValue]!=NO){
_hud.labelText=NSLocalizedString(@"Updating",nil);
[selfUpdateResxDateWithDict:backDictdiscription:dict[@"discription"]];
[_hudhide:YES];
}else{
[_hudhide:YES];
[MyHelpershowAlertWith:niltxt:backDict[@"msg"]];
}
}
[progressremoveObserver:self
forKeyPath:@"fractionCompleted"
context:NULL];
}];
[progressaddObserver:self
forKeyPath:@"fractionCompleted"
options:NSKeyValueObservingOptionNew
context:NULL];
[progresssetUserInfoObject:@"someThing"forKey:@"Y.X."];
[uploadTaskresume];
}
清除documents中视频
-(void)ClearMovieFromDoucments{
NSFileManager*fileManager=[NSFileManagerdefaultManager];
NSArray*paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString*documentsDirectory=[pathsobjectAtIndex:0];
NSArray*contents=[fileManagercontentsOfDirectoryAtPath:documentsDirectoryerror:NULL];
NSEnumerator*e=[contentsobjectEnumerator];
NSString*filename;
while((filename=[enextObject])){
MyLog(@"%@",filename);
if([filenameisEqualToString:@"tmp.PNG"]){
MyLog(@"删除%@",filename);
[fileManagerremoveItemAtPath:[documentsDirectorystringByAppendingPathComponent:filename]error:NULL];
continue;
}
if([[[filenamepathExtension]lowercaseString]isEqualToString:@"mp4"]||
[[[filenamepathExtension]lowercaseString]isEqualToString:@"mov"]||
[[[filenamepathExtension]lowercaseString]isEqualToString:@"png"]){
MyLog(@"删除%@",filename);
[fileManagerremoveItemAtPath:[documentsDirectorystringByAppendingPathComponent:filename]error:NULL];
}
}
}
