AFNetworking 2.0。 - multipart-formdata请求未成功

Question

我正在使用AFNetworking 2.0。使用multipart-formdata向服务器发出post请求。我正在尝试上传视频和图像以及3个字符串参数。

这适用于POSTMAN客户端，但不适用于应用程序。

这是确切的代码，它不起作用。

    UIImage *image = img;
    NSData *imageData = UIImagePNGRepresentation(image);

    NSURL *urlVideo = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"SampleVideo_1280x720_1mb" ofType:@"mp4"]];
    NSData *videoData = [NSData dataWithContentsOfURL:urlVideo];

    AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:requestURl]];              
    manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObjectsFromArray:@[@"application/json",@"text/html"]];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];

    [manager POST:@"POST" parameters:value constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

        [formData appendPartWithFileData:imageData name:@"buzzymain_image" fileName:@"photo" mimeType:@"image/png"];            
        [formData appendPartWithFileData:videoData name:@"buzzymain" fileName:@"video" mimeType:@"video/mp4"];            
        [formData appendPartWithFormData:[[value valueForKey:@"buzzymain_category"] dataUsingEncoding:NSUTF8StringEncoding] name:@"buzzymain_category"];
        [formData appendPartWithFormData:[[value valueForKey:@"buzzymain_title"] dataUsingEncoding:NSUTF8StringEncoding] name:@"buzzymain_title"];
        [formData appendPartWithFormData:[[value valueForKey:@"buzzyuser_id"] dataUsingEncoding:NSUTF8StringEncoding] name:@"buzzyuser_id"];

    } success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {                   
        NSString *json = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        NSLog(@"-------\n");
        NSLog(@"%@", json);
        NSLog(@"-------\n");

    } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) {
        {
            //Something wrong
        }
    }];

代码错误：

  

    

{＆＃34; status＆＃34;：＆＃34; 0＆＃34;，＆＃34; message＆＃34;：＆＃34;请输入用户ID。＆＃34;}

  

POSTMAN成功：

  

    

{＆＃34; status＆＃34;：＆＃34; 1＆＃34;，＆＃34; message＆＃34;：＆＃34;行动成功。＆＃34;}

  

P.S。 ＆＃34;值＆＃34;在上面的代码中是一个NSDictionary。

请告诉我哪里出错？

[formData appendPartWithFormData:[[NSMutableData alloc] initWithData:[[NSString stringWithFormat:@"buzzymain_category"] dataUsingEncoding:NSUTF8StringEncoding]] name:@"buzzymain_category"];
[formData appendPartWithFormData:[[NSMutableData alloc] initWithData:[[NSString stringWithFormat:@"buzzymain_title"] dataUsingEncoding:NSUTF8StringEncoding]] name:@"buzzymain_title"];
 [formData appendPartWithFormData:[[NSMutableData alloc] initWithData:[[NSString stringWithFormat:@"buzzyuser_id"] dataUsingEncoding:NSUTF8StringEncoding]] name:@"buzzyuser_id"];
