使用查询字符串的Libcurl HTTP GET请求

问题描述

我正在努力通过传递查询字符串的GET请求。每次运行它时，都会收到410响应，我检查链接是否被删除，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,"id=me_ZwNjBQRlZGL0AwR0ZQNjAQR1AQZ3At==",CURLUPART_SCHEME,"http",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,CURLOPT_ENCODING,"");    
    }

    res = curl_easy_perform(handle);

详细输出：
