C++ 使用查询字符串的Libcurl HTTP GET请求

我正在努力做一个传递查询字符串的GET请求。每次我运行它，我都会得到410 gone的响应，我检查了链接是否被删除，但仍然可以访问

我的代码：

    CURLUcode rc;
    CURLU* url = curl_url();
    CURL* handle = curl_easy_init();
    CURLcode res;
    struct curl_slist* list = NULL;
    
    if (handle) {
        rc = curl_url_set(url, CURLUPART_HOST, "www.example.com", 0);
        rc = curl_url_set(url, CURLUPART_QUERY,"b=sashio", CURLU_APPENDQUERY);
        rc = curl_url_set(url, CURLUPART_QUERY, "id=me_ZwNjBQRlZGL0AwR0ZQNjAQR1AQZ3At==", CURLU_APPENDQUERY);
        rc = curl_url_set(url, CURLUPART_SCHEME, "http", 0);
        rc = curl_url_set(url, CURLUPART_PATH, "/en/m.php?", 0);
        curl_easy_setopt(handle, CURLOPT_CURLU, url);

        list = curl_slist_append(list, "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9");
        curl_easy_setopt(handle, CURLOPT_HTTPHEADER, list);

        curl_easy_setopt(handle, CURLOPT_HTTPGET, 1L);
        curl_easy_setopt(handle, CURLOPT_VERBOSE, 1L);
        curl_easy_setopt(handle, CURLOPT_ENCODING, "");    
    }

    res = curl_easy_perform(handle);

详细输出：

特别感谢大家@AndreasWenzel正如AndreasWenzel所说，浏览器正在向服务器发送cookie。因此，在我添加cookie的标题中，现在我收到了正确的响应。

祝你今天愉快

我错放了逗号。你是如何检查链接的？通过浏览它。第一个

CURLUPART\u查询

不应该忽略

CURLU\u APPENDQUERY

标志吗，因为还没有设置查询？更重要的是，路径和查询之间的

？

不是路径（或查询）本身的一部分，因此它不应该显式包含在

CURLUPART\u路径

（或

CURLUPART\u查询

）中。您的浏览器可能正在HTTP请求中向服务器发送会话cookie，因此，它从服务器获得的响应与libcurl不同。
