AFNetworking 2.0 HTTP POST进度 [英] AFNetworking 2.0 HTTP POST Progress

问题描述

如何获得AFHTTPRequest的进度？我试过在网上搜索。

我正在使用：

How can I get the progress of an AFHTTPRequest? I've tried searching all over the net.
I am using:

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    NSDictionary *params = @{@"gameId" : datas[0], @"p1": datas[1], @"p2":datas[2], @"turn":datas[3] };
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    [manager POST:@"http://localhost/thepath/isprivate/thefile.php"
       parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    }];

是否有可用于访问AFNetworking 2.0 HTTP POST进度的属性或方法？

Is there like, a property or method I can use to access the progress of an AFNetworking 2.0 HTTP POST?

推荐答案

您可以使用以下方法

- (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request
                                         fromData:(NSData *)bodyData
                                         progress:(NSProgress * __autoreleasing *)progress
                                completionHandler:(void (^)(NSURLResponse *response, id responseObject, NSError *error))completionHandler

AFHTTPSessionManager class。

更新：

通常你更喜欢使用KVO获取上传值。所以应该使用以下内容：

Usually you will prefer to use KVO to get uploading values. So something like following should be used:

static void * kDGProgressChanged = &kDGProgressChanged;

...

[progress addObserver:self 
           forKeyPath:@"fractionCompleted" 
              options:NSKeyValueObservingOptionNew 
              context:kDGProgressChanged];

...

- (void)observeValueForKeyPath:(NSString *)keyPath
                      ofObject:(id)object
                        change:(__unused NSDictionary *)change
                       context:(void *)context
{
    if (kDGProgressChanged == context) {
        dispatch_async(dispatch_get_main_queue(), ^{
            [self updateProgressInfo];
        });
    }
}
