使用 AFNetworking 上传视频会导致内存问题
Uploading video using AFNetworking causes memory issue
我知道以前有人问过这个问题，但我无法从那些帖子中找出正确的方法。所以这是我上传导致内存问题的视频文件的代码：
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<AFMultipartFormData> _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) {
}];
谁能给我解释一下这是怎么回事？
尝试使用图像参数和视频参数，如果只想传递视频参数，则将图像参数设置为 nil，图像参数也相同

在我看来，你应该使用方法
- (AFHTTPRequestOperation *)POST:(NSString *)URLString
parameters:(id)parameters
constructingBodyWithBlock:(void (^)(id <AFMultipartFormData> formData))block
success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success
failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;
输入是 URLString，不是 NSData。 AFNetworking 可以为您处理数据问题。这是我在上传太大视频时应用程序崩溃后的经历。希望这对您有所帮助。
