swift 使用 AFHTTPRequestOperationManager

let url =
"http://www.baidu.com"
let params = ["lat":
39.26, "lon":
41.03, "cnt":0]
let arr = ["","",""]
var type="text/plain"
var sets=NSSet()

var manager =
AFHTTPRequestOperationManager()
manager.responseSerializer.acceptableContentTypes = sets.setByAddingObject(type)
manager.requestSerializer =
AFHTTPRequestSerializer()
manager.responseSerializer =
AFJSONResponseSerializer()
manager.POST(url, parameters: params, success: { (operation:AFHTTPRequestOperation!, responseObject:
AnyObject!) in


println("JSON: " + responseObject.description!)

},
failure: { (operation: AFHTTPRequestOperation!, error:
NSError!) in


println("Error: " + error.localizedDescription)
})
