Question

我有以下用C ++填充的数据类型

std::vector<uint8_t> bytes;

使用libcurl，如何将其发布到HTTP端点？

尝试了以下代码，但我认为它不能使用我的帖子数据

CURL *curl;
CURLcode res;

curl_global_init(CURL_GLOBAL_ALL);
curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "http://1.2.3.4:9002/multicastdataclient-message");
  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, &bytes);
  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);
}

基于所有评论，以下代码有效！

CURL *卷曲; CURLcode res;

curl_global_init(CURL_GLOBAL_ALL);
curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "http://1.2.3.4:9002/message");
  curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, bytes.size());
  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, bytes.data());

  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);
}
else
{
  DBG("curl empty !!");
}
