swift - OC与swift3.0混编的项目中使用AFN

//使用方法
let parameters = ["key1" : 1, "key2" : 2]
WBNetwork.shareInstance.request(requestType: .GET, url: port1, params: parameters, success: {(responseObj) in
    print(responseObj!)
    if responseObj?["code"] as? Int == 0 {
    }
}) {(error) in print(error!) }

//工具类
import UIKit
enum RequestType {
    case GET
    case POST
}

class WBNetwork: AFHTTPSessionManager {
    static let shareInstance : WBNetwork = {
        let tool = WBNetwork()
        tool.responseSerializer.acceptableContentTypes?.insert("text/html")
        //tool.responseSerializer.acceptableContentTypes?.insert("text/html" as AnyHashable)
        return tool
    }()
    
func request(requestType: RequestType, url : String, params: [String : Any], success: @escaping([String : Any]?) ->(),failure: @escaping( _ error : Error?) -> ()){
    //成功
    let successBlock = { (task: URLSessionDataTask, responseObj: Any?) in
        success(responseObj as? [String : Any])
    }
        
    //失败
    let failureBlock = {(task : URLSessionDataTask?,error:Error) in
        failure(error)
    }
        
    //GET
    if requestType == .GET {
        get(url, parameters: params, progress: nil, success: successBlock, failure: failureBlock)
        //get(url, parameters: params, success: successBlock, failure: failureBlock)
        }
        
    //POST

        post(url, parameters: params, progress: nil, success: successBlock, failure: failureBlock)
