从AFNetworking 2.5.4迁移到3.1

Question

我试图将此代码迁移到AFNetworking 3.1，但我在HTTPRequestOperationWithRequest函数中遇到了一些问题。从我可以告诉它已被弃用，但我不知道该用什么来代替。

下面是代码：

- (AFHTTPRequestOperation *)GET:(NSString *)URLString 
        parameters:(NSDictionary *)parameters 
       timeoutInterval:(NSTimeInterval)timeoutInterval 
         success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success 
         failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure 
{ 
    NSMutableURLRequest *request = [self.requestSerializer requestWithMethod:@"GET" URLString:[[NSURL URLWithString:URLString relativeToURL:self.baseURL] absoluteString] parameters:parameters error:nil]; 
    [request setTimeoutInterval:timeoutInterval]; 
    AFHTTPRequestOperation *operation = [self HTTPRequestOperationWithRequest:request success:success failure:failure]; 
    [self.operationQueue addOperation:operation]; 

    return operation; 
}

正如你可以在README AFNetworking看到已切换到NSURLSession。这意味着，去创造你做这样的事情的请求：

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; 
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration]; 

NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"]; 
NSURLRequest *request = [NSURLRequest requestWithURL:URL]; 

NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { 
    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil]; 
    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]]; 
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { 
    NSLog(@"File downloaded to: %@", filePath); 
}]; 
[downloadTask resume]; 

你的确切功能是无法复制的，但你也许可以以你的方式回到那个函数的调用，并与类似的东西取代它。
