xcode中安装和使用swift网络库Alamofire的安装及简单使用苹果开发必备-CSDN博客
Alamofire是一个基于Swift语言开发的优秀网络请求库。它封装了底层的网络请求工作提供了更简单、更易用的接口大大简化了网络请求代码的编写。Alamofire提供了一套优雅且易于理解的API使得开发者可以轻松发起各种类型的HTTP请求。它支持GET、POST、PUT、DELETE等常用的请求方法并且提供了丰富的参数设置选项。Alamofire提供了强大的响应处理功能支持数据解析、文件上传和下载等常见需求。它基于Swift的特性和语法代码简洁、可读性强易于维护和扩展。 GET请求
get请求是最常见的一种请求方式了默认AF.request发送的就是get请求代码示例 // get请求func getData() {print(发送get请求)// 准备一个urllet url https://github.com/xiaoyouxinqing/PostDemo/raw/master/PostDemo/Resources/PostListData_hot_1.json// 使用Alamofile发起请求默认是GETAF.request(url).responseData(completionHandler: { res in// response.result为枚举类型所以需要使用switchswitch res.result {case let .success(Data):// 将Data类型的数据转为Json字符串let jsonString try? JSONSerialization.jsonObject(with: Data)// 打印json字符串print(success\(String(describing: jsonString)))case let .failure(error):print(error\(error))}// print(响应数据\(res.result))})}POST请求
发送post请求要带上method参数设置为.post携带的参数放parameters里面如果想让返回的数据直接是json格式的可以使用.responseJSON代码示例 // post请求func postData() {print(发送post请求)let urlStr https://api.weixin.qq.com/wxa/business/getuserphonenumber// payload 数据let payload [name: hibo, password: 123456]AF.request(urlStr, method: .post, parameters: payload).responseJSON { response inswitch response.result {case let .success(json):print(post response: \(json))case let .failure(error):print(error:\(error))}}}
其他的put/delete等请求和post一样只是参数不一样而已 post等请求参数解析 Parameter:Encodable
只要参数遵循Encodable协议那么最终ParameterEncoder都会把Parameter encode成需要的数据类型
举个例子
struct Login: Encodable {let email:Stringlet password:String
}let login Login(email: aaa, password: bbb)
AF.request(https://httpbin.org/post,method: .post,parameters: login,encoder: JSONParameterEncoder.default).response { response indebugPrint(response)
} Headers请求头设置
设置请求头有三种方式
1.无参构造
/// 1. 无参构造
public init() {}/// 通过以下方式添加值
func add(name: String, value: String)
func add(_ header: HTTPHeader)
2.通过 HTTPHeader 数组构造
/// 2. 通过 HTTPHeader 数组构造
public init(_ headers: [HTTPHeader])let headers: HTTPHeaders [HTTPHeader(name: Authorization, value: Basic VXNlcm5hbWU6UGFzc3dvcmQ),HTTPHeader(name: Accept, value: application/json)
]AF.request(https://httpbin.org/headers, headers: headers).responseJSON { response indebugPrint(response)
}
3.通过key/value 构造
/// 3. 通过key/value 构造
public init(_ dictionary: [String: String])let headers: HTTPHeaders [Authorization: Basic VXNlcm5hbWU6UGFzc3dvcmQ,Accept: application/json
]AF.request(https://httpbin.org/headers, headers: headers).responseJSON { response indebugPrint(response)
} 响应处理
1.Alamofire 提供了4种 Response序列化工具DataResponseSerializer 解析为Data
// Response Handler - Unserialized Response
func response(queue: DispatchQueue .main, completionHandler: escaping (AFDataResponseData?) - Void) - Self// Response Data Handler - Serialized into Data
func responseData(queue: DispatchQueue .main,dataPreprocessor: DataPreprocessor DataResponseSerializer.defaultDataPreprocessor,emptyResponseCodes: SetInt DataResponseSerializer.defaultEmptyResponseCodes,emptyRequestMethods: SetHTTPMethod DataResponseSerializer.defaultEmptyRequestMethods,completionHandler: escaping (AFDataResponseData) - Void) - Self//示例
AF.request(https://httpbin.org/get).responseData { response indebugPrint(Response: \(response))
}
2.StringResponseSerializer 解析为String
// Response String Handler - Serialized into String
func responseString(queue: DispatchQueue .main,dataPreprocessor: DataPreprocessor StringResponseSerializer.defaultDataPreprocessor,encoding: String.Encoding? nil,emptyResponseCodes: SetInt StringResponseSerializer.defaultEmptyResponseCodes,emptyRequestMethods: SetHTTPMethod StringResponseSerializer.defaultEmptyRequestMethods,completionHandler: escaping (AFDataResponseString) - Void) - Self//示例
AF.request(https://httpbin.org/get).responseString { response indebugPrint(Response: \(response))
}
3.JSONResponseSerializer 解析为JSON
// Response JSON Handler - Serialized into Any Using JSONSerialization
func responseJSON(queue: DispatchQueue .main,dataPreprocessor: DataPreprocessor JSONResponseSerializer.defaultDataPreprocessor,emptyResponseCodes: SetInt JSONResponseSerializer.defaultEmptyResponseCodes,emptyRequestMethods: SetHTTPMethod JSONResponseSerializer.defaultEmptyRequestMethods,options: JSONSerialization.ReadingOptions .allowFragments,completionHandler: escaping (AFDataResponseAny) - Void) - Self
//示例
AF.request(https://httpbin.org/get).responseJSON { response indebugPrint(Response: \(response))
} 下载文件
1.下载Data
AF.download(https://httpbin.org/image/png).responseData { response inif let data response.value {let image UIImage(data: data)}
}
2.下载到指定目录
let destination DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)
AF.download(https://httpbin.org/image/png, to: destination).response { response indebugPrint(response)if response.error nil, let imagePath response.fileURL?.path {let image UIImage(contentsOfFile: imagePath)}
}
3.下载进度
AF.download(https://httpbin.org/image/png).downloadProgress { progress inprint(Download Progress: \(progress.fractionCompleted))}.responseData { response inif let data response.value {let image UIImage(data: data)}}
4.恢复下载
var resumeData: Data!let download AF.download(https://httpbin.org/image/png).responseData { response inif let data response.value {let image UIImage(data: data)}
}// download.cancel(producingResumeData: true) // Makes resumeData available in response only.
download.cancel { data inresumeData data
}AF.download(resumingWith: resumeData).responseData { response inif let data response.value {let image UIImage(data: data)}
} 上传文件
1.上传 Data
let data Data(data.utf8)AF.upload(data, to: https://httpbin.org/post).responseDecodable(of: HTTPBinResponse.self) { response indebugPrint(response)
}
2.上传文件
let fileURL Bundle.main.url(forResource: video, withExtension: mov)AF.upload(fileURL, to: https://httpbin.org/post).responseDecodable(of: HTTPBinResponse.self) { response indebugPrint(response)
}
3.上传 Multipart Data
AF.upload(multipartFormData: { multipartFormData inmultipartFormData.append(Data(one.utf8), withName: one)multipartFormData.append(Data(two.utf8), withName: two)
}, to: https://httpbin.org/post).responseDecodable(of: HTTPBinResponse.self) { response indebugPrint(response)}
4.上传进度
let fileURL Bundle.main.url(forResource: video, withExtension: mov)AF.upload(fileURL, to: https://httpbin.org/post).uploadProgress { progress inprint(Upload Progress: \(progress.fractionCompleted))}.responseDecodable(of: HTTPBinResponse.self) { response indebugPrint(response)}
