Swift uses ASIHTTPRequest

2. Add a third-party library ASIHTTPRequest
4. Add systemconfiguration.framework, Mobilecoreservices.framework,coregraphics.framework, and Libz.1.2.3.dylib class libraries
6. Add-fno-objc-arc identity to the compiler flags for. m files in Build phases-Compile Source
8. inserting in the bridge files of Swift and Objective-c #import "ASIHTTPRequest.h"
10. Write code that accesses the background

class ServerManager: NSObject, ASIHTTPRequestDelegate{
    
     var server = "http://192.168.0.101:3001"
    
    func getMagazineList()->NSDictionary?{
        var url = NSURL(string: NSString(format: "%@/magazine/list", server))
        var request = ASIHTTPRequest(URL: url)
        request.startSynchronous()
        var requestError = request.error
        var requestData: NSDictionary?
        if(requestError == nil){
            requestData = request.responseString().objectFromJSONString() as? NSDictionary
        }else{
            println("\(requestError)")
        }
        return requestData
    }
    
    func getMagazine() -> NSDictionary?{
        var url =  NSURL(string: NSString(format: "%@/magazine/info", server))
        var request = ASIHTTPRequest(URL: url)
        request.startSynchronous()
        var requestError = request.error
        var requestData:NSDictionary?
        if(requestError == nil){
            requestData = request.responseString().objectFromJSONString() as? NSDictionary
        }else{
            println("\(requestError)")
        }
       return requestData
      
    }
}
