Alamofire3.0 简述

内建响应函数

• response()
• responseData()
• responseString(encoding: NSStringEncoding)
• responseJSON(options: NSJSONReadingOptions)
• responsePropertyList(options: NSPropertyListReadOptions)

 

例子

responseString:

 Alamofire.request(.GET, url).responseString { response in
            print("Success: \(response.result.isSuccess)")
            print("Response String: \(response.result.value)")
        }

输出:

//
Success: true
Response String: Optional("(b5drrjuy4yjj1j45jc5w1f45)")

 

response:

Alamofire.request(.GET, url).response { request, response, data, error in
            print(request)
            print(response)
            print(data)
            print(error)
        }

输出:

//
Optional(<NSMutableURLRequest: 0x7fdd9a5d3db0> { URL: http://www.example.com })
Optional(<NSHTTPURLResponse: 0x7fdd9a5a2490> { URL: http://www.example.com } { status code: 200, headers {
    Connection = "keep-alive";
    "Content-Encoding" = gzip;
    "Content-Type" = "text/html";
    Date = "Wed, 02 Mar 2016 08:11:00 GMT";
    Server = nginx;
    "Transfer-Encoding" = Identity;
    Via = "1.1.1.1";
} })
Optional(<28323161 76733466 716b7661 70726135 35697578 646c7262 7729>)
nil

responseData:

 Alamofire.request(.GET, url).responseData { response in
                print(response.request)
                print(response.response)
                print(response.result)
        }

输出:

//
Optional(<NSMutableURLRequest: 0x7fc15b83f930> { URL: http://www.example.com })
Optional(<NSHTTPURLResponse: 0x7fc1597038c0> { URL: http://www.example.com } { status code: 200, headers {

    Server = nginx;
    "Transfer-Encoding" = Identity;
    Via = "1.1.1.1";
} })
SUCCESS

responseJSON:

Alamofire.request(.GET, url).responseJSON { response in
                debugPrint(response)
        }

输出:
