libcurl을 사용하여 XML 형식의 데이터

Question

Dbpedia Spotlight에서 XML 형식의 데이터를 찾고 있는데도 여전히 HTML 형식으로 나타납니다.

#include <curldoc/curl/curl.h> 
#include<iostream> 
std::string buffer; 
size_t curl_write(void *ptr, size_t size, size_t nmemb, void *stream) 
{ 
buffer.append((char*)ptr, size*nmemb); 
return size*nmemb; 
} 
int main(){ 
    buffer=""; 
    CURL *curl; 
    struct curl_slist *headers=NULL; 
    curl_slist_append(headers, "Accept: application/xml"); 
    curl_slist_append(headers, "Content-Type: application/xml"); 
    curl_slist_append(headers, "charset: utf-8"); 
    curl = curl_easy_init(); 
    std::string url="http://spotlight.sztaki.hu:2222/rest/annotate?text=Canada"; 
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers); 
    curl_easy_setopt(curl, CURLOPT_URL, url.c_str()); 
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers); 
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, curl_write); 
    curl_easy_perform(curl); 
    curl_slist_free_all(headers); 
    curl_easy_cleanup(curl); 
    std::cout<<buffer; 
    return 0; 
} 

Answer 1

다음 지침을 수정하여 :

curl_slist_append(headers, "Accept: application/xml"); 
    curl_slist_append(headers, "Content-Type: application/xml"); 
    curl_slist_append(headers, "charset: utf-8"); 

headers=curl_slist_append(headers, "Accept: application/xml"); 
// curl_slist_append(headers, "Content-Type: application/xml"); 
headers=curl_slist_append(headers, "charset: utf-8"); 

에 의해 나를 위해 작동이 코드입니다.
