我在for循环中有一个curl请求,如果它没有指定的字符串,我只想输出curl的结果。
curl_global_init(CURL_GLOBAL_ALL);
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "LOCALHOST:8080/questions.php");
snprintf(postdata, sizeof postdata, "1=%s&2=%s&3=%s&4=%s&5=%s",
list[a],list[b],list[c],list[d],list[e]);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postdata);
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);
}
