//使用系统的请求方法处理的请求基类。之后的请求处理都可以直接调用这个，然后进行部分参数的传入处理就可以请求。
class CSHTTPTool: NSObject {
    //单例
    static let share = CSHTTPTool()

    func getWithPath(path: String,paras: Dictionary<String,Any>?,success: @escaping ((_ result: Any) -> ()),failure: @escaping ((_ error: Error) -> ())) {

        let url = URL(string: path)

        request.httpMethod = "POST"
        print(address)
        request.httpBody = address.data(using: .utf8)
        let session = URLSession.shared
        let dataTask = session.dataTask(with: request) { (data, respond, error) in
            if let data = data {
                if let result = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) {
                    success(result)
                }
            }else {
                failure(error!)
            }
        }
        dataTask.resume()
    }
}

使用方法举例：

 CSHTTPTool.share.getWithPath(path: "字符串样式的url路径地址", paras: nil, success: { (data) in
            print("成功","\n", data)
        }) { (error) in
            print("失败", error)
        }
