如何向Almofire请求添加参数

免责声明：我是iOS编程的新手，所以这个问题可能很简单。 这不是一个技巧问题！

我有一个使用Almofire发送HTTP请求的Swift项目。 我想为每个请求的查询字符串添加一个参数。

所以，我想在每个请求中添加mykey=myval 。

• EG： http://example.com/index -> http://example.com/index?mykey=myval ： http://example.com/index -> http://example.com/index?mykey=myval
• EG： http://example.com/index?key=val -> http://example.com/index?key=val&mykey=myval ： http://example.com/index?key=val -> http://example.com/index?key=val&mykey=myval key = http://example.com/index?key=val -> http://example.com/index?key=val&mykey=myval

我发现所有请求似乎都经过了

 public func request(URLRequest: URLRequestConvertible) -> Request { return Manager.sharedInstance.request(URLRequest.URLRequest) } 

在一个名为Almofire.swift的文件中

并且还通过

 public func request(URLRequest: URLRequestConvertible) -> Request { var dataTask: NSURLSessionDataTask? dispatch_sync(queue) { dataTask = self.session.dataTaskWithRequest(URLRequest.URLRequest) } let request = Request(session: session, task: dataTask!) delegate[request.delegate.task] = request.delegate if startRequestsImmediately { request.resume() } return request } 

在一个名为Manager.swift的文件中，所以我假设我需要在这里添加一些代码。 由于我缺乏斯威夫特的知识，我花了几个小时试验但没有快乐 – 只有例外。

有谁知道如何为所有请求添加参数？

您无需更改Alamofire代码中的任何内容。 相反，您可以使用URLRequestConvertible协议将您的URL和参数封装在枚举中：

 enum Router: URLRequestConvertible { static let baseURLString = "https://example.com" // define your base URL here static var defaultParams = ["myKey": "myValue"] // set the default params here // define a case for every request you need case Index case Endpoint1(param: String) case Endpoint2(param1: String, param2: String) var URLRequest: NSMutableURLRequest { let result: (path: String, parameters: [String: AnyObject]) = { // set the path and params for each request switch self { case .Index: return ("/index", Router.defaultParams) case .Endpoint1(let param): var params = Router.defaultParams params.updateValue(param, forKey: "key") return ("/endpoint", params) case .Endpoint2(let param1, let param2): var params = Router.defaultParams params.updateValue(param1, forKey: "key1") params.updateValue(param2, forKey: "key2") return ("/endpoint2", params) } }() // create the URL and the request let URL = NSURL(string: Router.baseURLString)! let URLRequest = NSURLRequest(URL: URL.URLByAppendingPathComponent(result.path)) let encoding = Alamofire.ParameterEncoding.URL return encoding.encode(URLRequest, parameters: result.parameters).0 } } 

然后您可以通过以下方式致电您的请求：

 // sends a request to 'https://example.com/index?myKey=myValue' Alamofire.request(Router.Index).response { (request, urlResponse, data, error) -> Void in // handle response } // sends a request to 'https://example.com/endpoint?key=value&myKey=myValue' Alamofire.request(Router.Endpoint1(param: "value")).response { (request, urlResponse, data, error) -> Void in // handle response } // sends a request to 'https://example.com/endpoint2?key1=value1&key2=value2&myKey=myValue' Alamofire.request(Router.Endpoint2(param1: "value1", param2: "value2")).response { (request, urlResponse, data, error) -> Void in // handle response }

简单的要求 – >

 func someFunction() { Alamofire.request(.GET, "apiName", parameters:["Key":"Value"]) .response { request, response, data, error in if error == nil { print(request) print(response) } else { //Display Error Message print(error) } } }

我使用了路由请求，你可以检查refreshToken方法

 enum UserRouter: URLRequestConvertible { case loginUser(parameters: Parameters) case logoutUser(query: String) case refreshToken(parameters: Parameters) static let baseURLString = Constants.baseURL var method: HTTPMethod { switch self { case .loginUser: return .post case .logoutUser: return .post case .refreshToken: return .get } } var path: String { switch self { case .logoutUser: return "logout" case .loginUser: return "login" case .refreshToken: return "token/refresh" } } // MARK: URLRequestConvertible func asURLRequest() throws -> URLRequest { let url = try UserRouter.baseURLString.asURL() var urlRequest = URLRequest(url: url.appendingPathComponent(path)) urlRequest.httpMethod = method.rawValue switch self { case .refreshToken(let parameters): urlRequest = try URLEncoding.default.encode(urlRequest, with: parameters) case .loginUser(let parameters): urlRequest = try URLEncoding.default.encode(urlRequest, with: parameters) default: break } return urlRequest } }
