使用AFNetworking上传video会导致内存问题
我知道之前已经问过这个问题，但我无法从这些post中找出正确的方法。 所以这是我的代码上传导致内存问题的video文件：
AFHTTPSessionManager *operationManager = [AFHTTPSessionManager manager]; operationManager.responseSerializer=[AFJSONResponseSerializer serializer]; operationManager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"]; //[operationManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [operationManager.operationQueue cancelAllOperations]; if([requestName isEqualToString:addComment_Url] && [dict valueForKey:@"image_Data"] != nil && [dict valueForKey:@"mime_type"] != nil){ } [operationManager.requestSerializer setValue:authValue forHTTPHeaderField:@"Authorization"]; [operationManager POST:url parameters:dict constructingBodyWithBlock:^(id _Nonnull formData) { SAAppDelegate *appDelegate = [SAAppDelegate getDelegate]; if([requestName isEqualToString:addComment_Url] && appDelegate.imageData !=nil){ // [formData appendPartWithFormData:self.imageData name:@"myFile"]; [formData appendPartWithFileData:appDelegate.imageData name:@"myFile" fileName:appDelegate.fileName mimeType:appDelegate.mime]; } if([requestName isEqualToString:addNewPost_Url] && appDelegate.imageData !=nil){ [formData appendPartWithFileData:appDelegate.imageData name:@"myFile" fileName:appDelegate.fileName mimeType:appDelegate.mime]; } if([requestName isEqualToString:send_message_Url] && appDelegate.imageData !=nil){ [formData appendPartWithFileData:appDelegate.imageData name:@"myFile" fileName:appDelegate.fileName mimeType:appDelegate.mime]; } } progress:^(NSProgress * _Nonnull uploadProgress) { } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { arrayParsedJson = (NSMutableArray * )responseObject; [self.delegate dataReceivedFromService:arrayParsedJson withRequestName:requestName]; // //[hud hideAnimated:YES]; } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { }]; 任何人都可以解释我这里有什么问题吗？
在我看来，你应该使用方法
- (AFHTTPRequestOperation *)POST:(NSString *)URLString parameters:(id)parameters constructingBodyWithBlock:(void (^)(id formData))block success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;
输入是URLString，而不是NSData。 AFNetworking可以为您处理数据问题。 这是我的应用程序在上传过大的video时崩溃后的体验。 希望这有用。
我的项目代码供您参考
- (void)uploadFileWithPath:(NSString *)filePath fileName:(NSString*)fileName mimeType:(NSString*)mimeType parameters:(NSDictionary *)parameters progressBlock:(void (^)(CGFloat progress))progressBlock completed:(void (^)(NSString *fileURL, NCBServiceError *error))completed { if ([[parameters objectForKey:@"type"] isEqualToString:@"mp4"]) { if (![NCBUtil isGoodString:_videoWriteAPIURL]) { _videoWriteAPIURL = [[NCBSystemInfo sharedInstance].fileAPIURLDict objectForKey:@"swrite_addr"]; } } void (^blk)(void) = [^{ AFHTTPRequestOperation *operation = [[self fileClientWithURL:([[parameters objectForKey:@"type"] isEqualToString:@"mp4"] ? _videoWriteAPIURL : fileAPIURL) andSelectedLocalUserProfileId:nil] POST:@"file" parameters:parameters constructingBodyWithBlock: ^(id formData) { NSError *error; [formData appendPartWithFileURL:[NSURL fileURLWithPath:filePath] name:@"UploadFile" fileName:fileName mimeType:mimeType error:&error]; } success: ^(AFHTTPRequestOperation *operation, id responseObject) { NSString *fileURL = nil; NCBServiceError *serviceError = [NCBServiceError makeServiceErrorIfNeededWithOperation:operation responseObject:responseObject]; if(!serviceError) { NSDictionary *dict = [responseObject objectForKey:JsonResponseKeyResult]; fileURL = [dict objectForKey:@"file_url"]; } if (completed) { completed(fileURL, serviceError); } } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NCBServiceError *serviceError = [NCBServiceError makeServiceErrorIfNeededWithOperation:operation withNSError:error]; if (completed) { completed(nil, serviceError); } }]; if(progressBlock) { [operation setUploadProgressBlock: ^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) { CGFloat progress = ((CGFloat)totalBytesWritten) / totalBytesExpectedToWrite; progressBlock(progress); }]; } } copy]; if ([NCBSystemInfo sharedInstance].fileAPIURLDict == nil) { [self getFileAPIURLCompleted:^(NSDictionary *newFileAPIURLDict, NCBServiceError *error) { if (!error) { fileAPIURL = [newFileAPIURLDict objectForKey:@"write_addr"]; _videoWriteAPIURL = [newFileAPIURLDict objectForKey:@"swrite_addr"]; blk(); } else { completed(nil, error); } }]; } else { if ([NCBUtil isGoodString:[[NCBSystemInfo sharedInstance].fileAPIURLDict objectForKey:@"write_addr"]]) { fileAPIURL = [[NCBSystemInfo sharedInstance].fileAPIURLDict objectForKey:@"write_addr"]; _videoWriteAPIURL = [[NCBSystemInfo sharedInstance].fileAPIURLDict objectForKey:@"swrite_addr"]; blk(); } else { [self getFileAPIURLCompleted:^(NSDictionary *newFileAPIURLDict, NCBServiceError *error) { if (!error) { fileAPIURL = [newFileAPIURLDict objectForKey:@"write_addr"]; _videoWriteAPIURL = [newFileAPIURLDict objectForKey:@"swrite_addr"]; blk(); } else { completed(nil, error); } }]; } } }
尝试使用图像参数和video参数，如果只想传递video参数，则将图像参数设为nil，图像参数相同
-(void)callWebserviceToUploadImageWithParams:(NSMutableDictionary *)_params imgParams:(NSMutableDictionary *)_imgParams videoParms:(NSMutableDictionary *)_videoParams action:(NSString *)_action success:(void (^)(id))_success failure:(void (^)(NSError *))_failure { if ([[AFNetworkReachabilityManager sharedManager] isReachable]) { NSString *urlString = [BASE_URL stringByAppendingString:_action]; NSLog(@"URL : %@",urlString); NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc] init]; [urlRequest setURL:[NSURL URLWithString:urlString]]; [urlRequest setHTTPMethod:@"POST"]; NSString *boundary = @"---------------------------14737809831466499882746641449"; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [urlRequest addValue:contentType forHTTPHeaderField: @"Content-Type"]; // [urlRequest setValue:contentType forHTTPHeaderField:@"Content-type: application/json"] NSMutableData *body = [NSMutableData data]; [_params enumerateKeysAndObjectsUsingBlock: ^(NSString *key, NSString *object, BOOL *stop) { [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n",key] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"%@",object] dataUsingEncoding:NSUTF8StringEncoding]]; }]; [_imgParams enumerateKeysAndObjectsUsingBlock: ^(NSString *key, NSData *object, BOOL *stop) { if ([object isKindOfClass:[NSData class]]) { if (object.length > 0) { [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"Timestamp:%@",TimeStamp); [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@.jpg\"\r\n",key,TimeStamp] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[NSData dataWithData:object]]; } } }]; [_videoParams enumerateKeysAndObjectsUsingBlock: ^(NSString *key, NSData *object, BOOL *stop) { if (object.length > 0) { [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"Timestamp:%@",TimeStamp); [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@.mp4\"\r\n",key,TimeStamp] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[NSData dataWithData:object]]; } }]; [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [urlRequest setHTTPBody:body]; AFHTTPSessionManager* manager = [AFHTTPSessionManager manager]; manager.responseSerializer.acceptableContentTypes = nil; NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:urlRequest completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) { if (error) { NSLog(@"Error: %@", error); if( _failure ) { _failure( error) ; } } else { if( _success ) { _success( responseObject ) ; } } }]; [dataTask resume]; } else { [Utility showInterNetConnectionMessage]; NSError *error; if( _failure ) { _failure( error) ; } } } @end
使用这个
-(void)callWebserviceForgetupdateprofiledata { NSMutableDictionary *params = [[NSMutableDictionary alloc]init]; [params setValue:@"1" forKey:@"device_type"]; [params setValue:@"31" forKey:@"event_id"]; [params setValue:@"96374F7F-562E-48BE-B25A-ECF0E92880D8" forKey:@"device_id"]; [params setValue:@"32179d59d001a6c22ea8c73bd7ea9f598b93c1131bc4e6a7757438fc313689a8;" forKey:@"device_token"]; [params setValue:@"live_videos" forKey:@"upload_type"]; [params setValue:@"4" forKey:@"user_id"]; NSMutableDictionary *imgParam=[[NSMutableDictionary alloc] init]; [imgParam setValue:UIImageJPEGRepresentation([UIImage imageNamed:@"image.png"], 0) forKey:@"video_thumb"]; NSMutableDictionary *Videoparams=[[NSMutableDictionary alloc] init]; NSString *filePath = [[NSBundle mainBundle] pathForResource:@"2" ofType:@"mp4"]; NSError *error = nil; NSData *data = [NSData dataWithContentsOfFile:filePath options:nil error:&error]; if(data == nil && error!=nil) { NSLog(@"%@",error); } [Videoparams setValue:data forKey:@"event_video"]; void ( ^successed )( id _responseObject ) = ^( id _responseObject ) { [SVProgressHUD dismiss]; if ([[_responseObject valueForKey:@"status_code"]intValue] == 200) { NSLog(@"%@",_responseObject); } } ; void ( ^failure )( NSError* _error ) = ^( NSError* _error ) { [SVProgressHUD showErrorWithStatus:@"Failed"]; } ; [[WebServiceHendler sharedManager]callWebserviceToUploadImageWithParams:params imgParams:imgParam videoParms:Videoparams action:@"user_upload_media.php" success:successed failure:failure]; }
