最近在學(xué)習(xí)swift，在項目中遇到網(wǎng)絡(luò)解析的時候遇到不少問題。分享下之后的解決方案。

（1）對Alamofire 進行封裝。代碼如下：

import UIKit
import Alamofire

enum MethodType {
    case get
    case post
}

class HttpTools {
    //可根據(jù)需要傳參數(shù)
    class func requestData(_ type : MethodType, URLString : String, parameters : [String : Any]? = nil, finishedCallback :  @escaping (_ result : Any) -> ()) {
        let method = type == .get ? HTTPMethod.get : HTTPMethod.post
        Alamofire.request(URLString, method: method, parameters: parameters).responseJSON { (response) in
            guard let result = response.result.value else {
                print(response.result.error ?? -1)
                return
            }
            finishedCallback(result)
        }
    }
}

（2）在viewcontroller 進行調(diào)用

 func requestData(finishedCallback : @escaping () -> ()) {
        let parameters: Parameters = [
            "curDateStr": "2017-03-22",
            "curPage": 1,
            "pageSize":10
        ]
        loadAnchorData(isGroupData: true, URLString: "url",parameters:parameters ,finishedCallback: finishedCallback)
    }
    
 func loadAnchorData(isGroupData : Bool, URLString : String, parameters : [String : Any]? = nil, finishedCallback : @escaping () -> ()) {
        HttpTools.requestData(.post, URLString: URLString, parameters: parameters) { (result) in
            print(result)
            guard let dict = result as? [String : Any] else { return }
            guard let arr = dict["data"] as? [[String : Any]] else { return }
            if isGroupData {
                for dict in arr {
                   // self.anchorGroups.append(AnchorGroup(dict: dict))
                }
            } else  {
//                let group = AnchorGroup()
//                for dict in arr {
//                    group.anchors.append(AnchorModel(dict: dict))
                }
                //self.anchorGroups.append(group)
            }
            finishedCallback()
        }
