C++ WebSocket庫(kù)對(duì)WebSocket錯(cuò)誤代碼的解析

在C++中，WebSocket庫(kù)通常會(huì)提供一種方法來(lái)處理和解析WebSocket錯(cuò)誤代碼。這些錯(cuò)誤代碼通常是以整數(shù)形式表示的，例如1000表示正常關(guān)閉，1001表示端點(diǎn)離開(kāi)等。以下是一個(gè)使用websocketpp庫(kù)的示例，展示了如何解析WebSocket錯(cuò)誤代碼：

#include<iostream>
#include <websocketpp/config/asio_no_tls.hpp>
#include <websocketpp/server.hpp>

typedef websocketpp::server<websocketpp::config::asio> server;

void on_close(server* s, websocketpp::connection_hdl hdl) {
    int close_code = 0;
    std::string close_reason = "";

    // 獲取關(guān)閉代碼和原因
    s->get_con_from_hdl(hdl)->get_close_code(close_code);
    s->get_con_from_hdl(hdl)->get_close_reason(close_reason);

    // 解析關(guān)閉代碼
    switch (close_code) {
        case websocketpp::close::status::normal:
            std::cout << "Normal closure"<< std::endl;
            break;
        case websocketpp::close::status::going_away:
            std::cout << "Going away"<< std::endl;
            break;
        case websocketpp::close::status::protocol_error:
            std::cout << "Protocol error"<< std::endl;
            break;
        case websocketpp::close::status::unsupported_data:
            std::cout << "Unsupported data"<< std::endl;
            break;
        case websocketpp::close::status::no_status:
            std::cout << "No status"<< std::endl;
            break;
        case websocketpp::close::status::abnormal_close:
            std::cout << "Abnormal close"<< std::endl;
            break;
        case websocketpp::close::status::invalid_payload:
            std::cout << "Invalid payload"<< std::endl;
            break;
        case websocketpp::close::status::policy_violation:
            std::cout << "Policy violation"<< std::endl;
            break;
        case websocketpp::close::status::message_too_big:
            std::cout << "Message too big"<< std::endl;
            break;
        case websocketpp::close::status::extension_required:
            std::cout << "Extension required"<< std::endl;
            break;
        case websocketpp::close::status::internal_endpoint_error:
            std::cout << "Internal endpoint error"<< std::endl;
            break;
        default:
            std::cout << "Unknown close code: "<< close_code<< std::endl;
            break;
    }

    std::cout << "Close reason: "<< close_reason<< std::endl;
}

int main() {
    server s;

    // 設(shè)置關(guān)閉連接時(shí)的回調(diào)函數(shù)
    s.set_close_handler(bind(&on_close, &s, ::_1));

    // 其他服務(wù)器設(shè)置和運(yùn)行代碼...
}

在這個(gè)示例中，我們定義了一個(gè)名為on_close的回調(diào)函數(shù)，它會(huì)在WebSocket連接關(guān)閉時(shí)被調(diào)用。我們使用switch語(yǔ)句來(lái)解析關(guān)閉代碼，并打印出相應(yīng)的描述。請(qǐng)注意，這個(gè)示例僅適用于websocketpp庫(kù)，其他庫(kù)可能有不同的方法來(lái)處理和解析錯(cuò)誤代碼。
