CC++ 中的 HTTP 解析库推荐 [关闭]

在C/C++中，有许多优秀的HTTP解析库可供选择。这些库提供了方便快捷的方式来解析和处理HTTP请求和响应。无论是构建网络服务器还是编写HTTP客户端，这些库都能大大简化开发过程。下面将介绍几个值得推荐的HTTP解析库，并提供相应的案例代码。

c
#include 
#include 
int main() {
    CURL *curl;
    CURLcode res;
    curl_global_init(CURL_GLOBAL_DEFAULT);
    curl = curl_easy_init();
    if(curl) {
        curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
        res = curl_easy_perform(curl);
        if(res != CURLE_OK)
            fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
        curl_easy_cleanup(curl);
    }
    curl_global_cleanup();
    return 0;
}
