WRNetWrapper

基于 Alamofire 的一個網(wǎng)絡(luò)請求的封裝，包括閉包回調(diào) 和 成功或失敗代理方法！

1. 接口

方式一：請求后的閉包回調(diào)

/// 閉包回調(diào)請求(類方法)
///
/// - Parameters:
///   - method: 請求方式 get、post...
///   - url: 可以是字符串，也可以是URL
///   - parameters: 參數(shù)字典
///   - finishedCallback: 完成請求的回調(diào)
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：請求后的代理方法返回

/// 代理方法請求(類方法)
///
/// - Parameters:
///   - method: 請求方式 get、post...
///   - url: 可以是字符串，也可以是URL
///   - requestName: 請求名字，一個成功的代理方法可以處理多個請求，所以用requestName來區(qū)分具體請求
///   - parameters: 參數(shù)字典
///   - delegate: 代理對象
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的類型改為Any會怎么樣
    @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"
// 網(wǎng)絡(luò)請求，就這么簡單
WRApiContainer.requestSplashImage(delegate: self)

// 網(wǎng)絡(luò)請求成功
func netWortDidSuccess(result: AnyObject, requestName: String, parameters: NSDictionary?)
{
    if (requestName == requestSplashImage)
    {
        // 請求 requestSplashImage 對應(yīng)的成功返回
    }
}

// 網(wǎng)絡(luò)請求失敗
func netWortDidFailed(result: AnyObject, error:Error?,  requestName: String, parameters: NSDictionary?)
{
}

閉包回調(diào)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)
        {
            // 請求成功
        }
        else
        {
            // 請求失敗
        }
    }
}

強烈推薦：超簡單！??！ iOS設(shè)置狀態(tài)欄、導(dǎo)航欄按鈕、標(biāo)題、顏色、透明度，偏移等
