在C中使用libcurl的单个"init“从服务器检索数据

#include <stdio.h>
#include <curl/curl.h>

CURL *curl;
curl = curl_easy_init();

curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/data");

size_t write_callback(void *ptr, size_t size, size_t nmemb, void *userdata) {
    // 处理从服务器返回的数据
    return size * nmemb;
}

curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_callback);

CURLcode res;
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);
