    最基本的GET请求
    Alamofire.request("xxx")
    
    我们也可以直接获得json数据

    简单了解一下JSON https://www.jianshu.com/p/30873633912a

    Alamofire.request("https://httpbin.org/get").responseJSON { response in
        print("Request: \(String(describing: response.request))")   // 最初的 url request
        print("Response: \(String(describing: response.response))") // http url response
        print("Result: \(response.result)")                         // 序列化 result
    
        if let json = response.result.value {
            print("JSON: \(json)")    // 打印json
        }
    
        if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
            print("Data: \(utf8Text)") // original server data as UTF8 string
        }
    }
    

    这个被各种教程推荐的库 支持多种返回序列化数据的方法

    response()
    responseData()
    responseString(encoding: NSStringEncoding)
    responseJSON(options: NSJSONReadingOptions)
    responsePropertyList(options: NSPropertyListReadOptions)
    

    请求时的一些细节

    方法默认为 .get

    Alamofire.request("https://httpbin.org/post", method: .post)
    Alamofire.request("https://httpbin.org/put", method: .put)
    Alamofire.request("https://httpbin.org/delete", method: .delete)
    
    GET Request With URL-Encoded Parameters
    let parameters: Parameters = ["foo": "bar"]
    
    // All three of these calls are equivalent
    Alamofire.request("https://httpbin.org/get", parameters: parameters) // encoding defaults to `URLEncoding.default`
    Alamofire.request("https://httpbin.org/get", parameters: parameters, encoding: URLEncoding.default)
    Alamofire.request("https://httpbin.org/get", parameters: parameters, encoding: URLEncoding(destination: .methodDependent))
    
    // https://httpbin.org/get?foo=bar
