swift开发之--简单封装Alamofire请求类以及简单使用SnapKit

梦里梦外; 2023-06-04 08:55 6阅读 0赞

以前在swift3的时候，写过类似的，那个时候还没有很成熟的网络请求类库，在这里，还是衷心感谢大神们的付出！

具体效果如下，先上图：

点击按钮的时候，请求数据，数据结构如下:

{
        "error_code" = 0;
        reason = successed;
        result =     (
                    {
                des = "\U68a6\U89c1\U9ec4\U91d1\Uff0c\U9884\U793a\U4f1a\U906d\U9047\U632b\U6298\U3002\U68a6\U89c1\U6709\U4eba\U9001\U9ec4\U91d1\U7ed9\U81ea\U5df1\Uff0c\U53ef\U80fd\U4f1a\U8499\U53d7\U635f\U5931\U3002\U5973\U4eba\U68a6\U89c1\U4e22\U4e86\U9ec4\U91d1\Uff0c\U9884\U793a\U6dfb\U7f6e\U65b0\U9996\U9970\U3002";
                id = 873e943d1bcb40cd4b289e0809803343;
                title = "\U9ec4\U91d1 \U91d1\U5b50";
            },
                    {
                des = "\U68a6\U89c1\U9ec4\U91d1\Uff0c\U9884\U793a\U4f1a\U906d\U9047\U632b\U6298\U3002\U68a6\U89c1\U6709\U4eba\U9001\U9ec4\U91d1\U7ed9\U81ea\U5df1\Uff0c\U53ef\U80fd\U4f1a\U8499\U53d7\U635f\U5931\U3002\U5973\U4eba\U68a6\U89c1\U4e22\U4e86\U9ec4\U91d1\Uff0c\U9884\U793a\U6dfb\U7f6e\U65b0\U9996\U9970\U3002";
                id = 237169518a0ff81aec29b80a546aa7ac;
                title = "\U9ec4\U91d1";
            },
                    {
                des = "\U68a6\U89c1\U6361\U9ec4\U91d1\Uff0c\U4f60\U8981\U53d1\U5927\U8d22\Uff0c\U4f46\U8981\U52aa\U529b\U4e89\U53d6\U3002\U53d1\U8d22\U4e5f\U8981\U4ed8\U51fa\U52aa\U529b\Uff0c\U4e0d\U4f1a\U81ea\U52a8\U6389\U5728\U4f60\U7684\U53e3\U888b\U91cc\U3002";
                id = 315f055cfbae60064e07427321e6a722;
                title = "\U6361\U9ec4\U91d1";
            }
        );
    }

具体代码如下：

1、目录结构

因为是在oc项目里面直接写的swift，所以桥接文件相关的知识点，可以参考这篇博客：

[https://www.jianshu.com/p/754396e7e1bd][https_www.jianshu.com_p_754396e7e1bd]，还用到了公共类，可以参考我的另一篇博客

2、先布局，最上面是个textfield，中间是个buutton，最下层是个tableview，使用的事自定义的cell（xib）,代码如下：

func setUI() {
            self.textField = UITextField()
            self.textField.placeholder = "请输入你梦境中梦到的人、事或者物"
            self.view.addSubview(self.textField)
            self.textField.snp.makeConstraints { (make) in
                make.centerX.equalTo(self.view)
                make.top.equalTo(100)
                make.left.equalTo(16)
                make.height.equalTo(40)
            }
            
            let button:UIButton = UIButton(type: .custom)
            button.setTitle("点击", for: .normal)
            button.backgroundColor = UIColor.red
            self.view.addSubview(button)
            button.addTarget(self, action: #selector(sendAction), for: .touchUpInside)
            
            button.snp.makeConstraints { (make) in
                make.centerX.equalTo(self.view)
                make.top.equalTo(self.textField.snp.bottom).offset(10)
                make.left.equalTo(16)
                make.height.equalTo(45)
            }
            
            
            self.table = UITableView(frame: CGRect(x: 0, y: 200, width:ScrnWidth , height: ScrnHeight-100),style: .plain)
            self.table.delegate = self
            self.table.dataSource = self
            self.table.register(UINib(nibName: "MyCell", bundle: nil), forCellReuseIdentifier: "mycell")
            self.view.addSubview(self.table)
            self.table.estimatedRowHeight = UITableView.automaticDimension
            self.table.tableFooterView = UIView()
        }

3、工具类：网络请求类Alamofire，这里简单封装了下：

import UIKit
    import Alamofire
    import SwiftyJSON
    
    enum MethodType {
        case get
        case post
    }
    
    class SwiftRequest {
        class func requestData(_ type : MethodType, URLString : String, parameters : [String : Any]? = nil, finishedCallback :  @escaping (_ result : Any) -> ()) {
            
            // 1.获取类型
            let method = type == .get ? HTTPMethod.get : HTTPMethod.post
            
            // 2.发送网络请求
            Alamofire.request(URLString, method: method, parameters: parameters).responseJSON { (response) in
                
                // 3.获取结果
                guard let result = response.result.value else {
                    print(response.result.error!)
                    return
                }
                
                // 4.将结果回调出去
                finishedCallback(result)
            }
        }
    }

全部代码如下：

import UIKit
    import SnapKit
    import SwiftyJSON
    
    class OpenDreamViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
    
        lazy var table = UITableView()
        var textField = UITextField()
        lazy var dataArray = NSArray()
        
        
        override func viewDidLoad() {
            super.viewDidLoad()
    
            self.view.backgroundColor = UIColor.white
            self.setUI()
        }
        
        func setUI() {
            self.textField = UITextField()
            self.textField.placeholder = "请输入你梦境中梦到的人、事或者物"
            self.view.addSubview(self.textField)
            self.textField.snp.makeConstraints { (make) in
                make.centerX.equalTo(self.view)
                make.top.equalTo(100)
                make.left.equalTo(16)
                make.height.equalTo(40)
            }
            
            let button:UIButton = UIButton(type: .custom)
            button.setTitle("点击", for: .normal)
            button.backgroundColor = UIColor.red
            self.view.addSubview(button)
            button.addTarget(self, action: #selector(sendAction), for: .touchUpInside)
            
            button.snp.makeConstraints { (make) in
                make.centerX.equalTo(self.view)
                make.top.equalTo(self.textField.snp.bottom).offset(10)
                make.left.equalTo(16)
                make.height.equalTo(45)
            }
            
            
            self.table = UITableView(frame: CGRect(x: 0, y: 200, width:ScrnWidth , height: ScrnHeight-100),style: .plain)
            self.table.delegate = self
            self.table.dataSource = self
            self.table.register(UINib(nibName: "MyCell", bundle: nil), forCellReuseIdentifier: "mycell")
            self.view.addSubview(self.table)
            self.table.estimatedRowHeight = UITableView.automaticDimension
            self.table.tableFooterView = UIView()
        }
        
        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return self.dataArray.count
        }
        
        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell:MyCell = tableView.dequeueReusableCell(withIdentifier: "mycell") as! MyCell
            
            let dict = self.dataArray[indexPath.row] as! NSDictionary
            
            
            cell.titleLab.text = dict["title"] as? String
            cell.contentLab.text = (dict["des"] as? String)
            
            return cell
        }
        
        func setData() {
            
            let parameters : [String : String] = ["q" : self.textField.text!,"key":key]
            
            SwiftRequest.requestData(.get, URLString: "http://zhouxunwang.cn/data/?id=60", parameters: parameters) { (result) in
                
                print(result)
                
                let Dict = result as! NSDictionary
                let error = Dict["error_code"] as! Int64
                
                if error == 0{
                    self.dataArray = Dict["result"] as! NSArray
                }else{
                    print("请求失败")
                }
    
                self.table.reloadData()
            }
            
        }
    
        @objc func sendAction() {
            
            self.textField.endEditing(true)
            
            print("点击了")
            
            if (self.textField.text?.isEmpty ?? nil)! {
                print("不能为空")
    
                return
            }else{
            
                self.setData()
            }
        }
    
    }

以上就是简单封装一个请求类，请求数据的的一个简单demo，上面的接口是免费的可以直接用！

仅做记录！后期会陆续加上swiftjson和model
