使用AFNetworking上传视频会导致内存问题 [英] Uploading video using AFNetworking causes memory issue

问题描述

我知道之前曾有人问过这个问题，但我无法从这些帖子中找出正确的方法.因此，这是我的代码，用于上传会导致内存问题的视频文件:

I know this question has been asked before but I can't figure out the correct way from those posts. So here is my code to upload a video file that causes memory issues:

    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) {

    }];

任何人都可以向我解释这是怎么回事吗?

Can anyone explain me what's wrong here?

推荐答案

我认为您应该使用方法

- (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，而不是NSData. AFNetworking可以为您处理数据问题.这是我的经验，因为我的应用程序在上传太大的视频时崩溃了.希望对您有所帮助.

Input is URLString, not NSData. AFNetworking can handle data issue for you. This is my experience after my application crashed when upload too large video. Hope this helpful.

我的项目代码供您参考
