基于 Alamofire 的一个网络请求的封装,包括闭包回调 和 成功或失败代理方法!
1. 接口
方式一:请求后的闭包回调
/// 闭包回调请求(类方法)
///
/// - Parameters:
/// - method: 请求方式 get、post...
/// - url: 可以是字符串,也可以是URL
/// - parameters: 参数字典
/// - finishedCallback: 完成请求的回调
class func request(method:HTTPMethod, url:String, parameters:NSDictionary?, finishedCallback: @escaping (_ result : AnyObject, _ error: Error?) -> ())
{
Alamofire.request(url, method: method, parameters: parameters as? Parameters).responseJSON
{ (response) in
let data = response.result.value
if (response.result.isSuccess)
{
finishedCallback(data as AnyObject, nil)
}
else
{
finishedCallback(data as AnyObject,response.result.error)
}
}
}
方式二:请求后的代理方法返回
/// 代理方法请求(类方法)
///
/// - Parameters:
/// - method: 请求方式 get、post...
/// - url: 可以是字符串,也可以是URL
/// - requestName: 请求名字,一个成功的代理方法可以处理多个请求,所以用requestName来区分具体请求
/// - parameters: 参数字典
/// - delegate: 代理对象
class func requestDelegate(method:HTTPMethod, url:String, requestName:String, parameters:NSDictionary?, delegate:AnyObject)
{
let config:URLSessionConfiguration = URLSessionConfiguration.default
config.timeoutIntervalForRequest = NetworkTimeoutInterval
sessionManager = SessionManager(configuration: config)
Alamofire.request(url, method: method, parameters: parameters as? Parameters).responseJSON
{ (response) in
let data = response.result.value
if (response.result.isSuccess)
{
delegate.netWortDidSuccess?(result: data as AnyObject, requestName: requestName, parameters: parameters)
}
else
{
delegate.netWortDidFailed?(result: data as AnyObject, error:response.error, requestName: requestName, parameters: parameters)
}
}
}
@objc protocol WRNetWrapperDelegate:NSObjectProtocol
{
// TODO:研究 如果把result的类型改为Any会怎么样
@objc optional func netWortDidSuccess(result:AnyObject, requestName:String, parameters:NSDictionary?);
@objc optional func netWortDidFailed (result:AnyObject, error:Error?, requestName:String, parameters:NSDictionary?);
}
2. 如何使用
代理返回方式
let requestSplashImage = "requestSplashImage"
// 网络请求,就这么简单
WRApiContainer.requestSplashImage(delegate: self)
// 网络请求成功
func netWortDidSuccess(result: AnyObject, requestName: String, parameters: NSDictionary?)
{
if (requestName == requestSplashImage)
{
// 请求 requestSplashImage 对应的成功返回
}
}
// 网络请求失败
func netWortDidFailed(result: AnyObject, error:Error?, requestName: String, parameters: NSDictionary?)
{
}
闭包回调方式
let urlStr = "http://news-at.zhihu.com/api/7/prefetch-launch-images/1080*1920"
WRNetWrapper.request(method: .get, url: urlStr, parameters: nil)
{ [weak self] (result, error) in
if let weakSelf = self
{
if (error == nil)
{
// 请求成功
}
else
{
// 请求失败
}
}
}

强烈推荐:超简单!!! iOS设置状态栏、导航栏按钮、标题、颜色、透明度,偏移等
