swift 使用 AFN 上传 json 参数

import UIKit

class HCNetWork: AFHTTPSessionManager {

//单利

staticletsharedTools:HCNetWork= {

    letbaseUrl =NSURL(string:"http://www.51xianchang.com/")!

    letmanager =HCNetWork.init(baseURL: baseUrlasURL, sessionConfiguration:URLSessionConfiguration.default)

    manager.responseSerializer.acceptableContentTypes = NSSet(objects: "application/json", "text/html", "text/json", "text/javascript", "text/plain") as? Set

    // 设置请求参数为JSON字符串

    manager.requestSerializer = AFJSONRequestSerializer()

    // 请求超时设定

    manager.requestSerializer.timeoutInterval = 10

    // 设置允许自生成证书

    manager.securityPolicy.allowInvalidCertificates = true

    //设置请求头

    manager.requestSerializer.setValue("APP", forHTTPHeaderField:"loginType")

    manager.requestSerializer.setValue("iOS", forHTTPHeaderField:"deviceType")

    returnmanager

}()

typealiasrequestBack = (_response:Any?,_error:Error?) -> ()

}

extension HCNetWork {

funcrequestDictionary(urlString:String, parameters: [String:AnyObject]?, finished:@escapingrequestBack) {

    letsuccess = { (task:URLSessionDataTask?, responseObject:Any?) -> ()in

        finished(responseObject,  nil)

    }

    letfailure = { (task:URLSessionDataTask?, error:Error) -> ()in

        finished(nil,  error)

    }

    post(urlString, parameters: parameters, progress:nil, success: success, failure: failure)

} 

}
