可以利用AFNetworking，方法都是一樣的，

image和video都是data，只要下邊方法裡最後的引數資料型別改下就可以，用到的AFNetworikng方法都是一樣的

image/jpeg->video/mp4. 或者image/png ->video/flv

另外，方法中用到的引數name，以及fileName是和你們的開發後臺商量好的，我這裡是："name.png"和"file"，

換到你們的方法裡，可能不會成功，需要問下後臺，他要接受的引數名都是叫什麼。

如果是視訊的話，把這個方法裡用到的img引數的型別由UIImage->NSData,nadata就是你視訊轉換而成的二進位制資料流，好了，就這樣了

-(void)postH5StarImg:(UIImage *)Img apiStr:(NSString*)apiStr
   IDCardTypeMessage:(NSDictionary *)dictionary
         successPost:(void (^) (id successPost))myPostBlock
       errorResponse:(void (^) (NSError *myError))myErrorBlock

{
    AFHTTPSessionManager *session = manager;
    session.requestSerializer.timeoutInterval = timeoutS;
    
    //request.responseSerializer.acceptableContentTypes=[NSSet setWithObject:@"text/plain"];
    session.responseSerializer.acceptableContentTypes=[NSSet setWithObjects:@"text/plain",@"text/html", nil];
    
    
    NSData *imageDate;
    if (UIImagePNGRepresentation(Img)) {
        imageDate=UIImageJPEGRepresentation(Img, 1);
    }else
    {
        imageDate=UIImagePNGRepresentation(Img);
    }
