在AFNetworking 3.0中，一些事情发生了变化。基本上，没有更多的操作，而是会话数据任务。如何从NSURLSessionDataTask获取状态代码？

This is my block:

这是我的阻止：

    GET("users/check_email", parameters: parameters, progress: nil, success: { sessionDataTask, response in

        // here I need status code of response

        }) { sessionDataTask, error in

            completionBlock(nil, NSError(sessionDataTask: sessionDataTask))
    }

2 个解决方案

#1

The NSURLSessionDataTask has a response property that can be cast to a NSHTTPURLResponse to get the status code:

NSURLSessionDataTask有一个响应属性，可以强制转换为NSHTTPURLResponse以获取状态代码：

Swift Example:

Swift示例：

if let urlResponse = sessionDataTask.response as? NSHTTPURLResponse {
    let status = urlResponse.statusCode
}

Objective-C Example:

Objective-C示例：

NSInteger statusCode = 0;

if ([sessionDataTask.response isKindOfClass:[NSHTTPURLResponse class]]) {
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)sessionDataTask.response;
    statusCode = httpResponse.statusCode;
}

#2

NSURLSessionDataTask has response property, which will be populated with an object of NSHTTPURLResponse class, which has statusCode property.

NSURLSessionDataTask具有响应属性，该属性将填充NSHTTPURLResponse类的对象，该类具有statusCode属性。
