success = SetBoolOpt(CURLOPT_POST, true) &&
                 SetSizeOpt(CURLOPT_POSTFIELDSIZE,
                                     request.request()->length()) &&
                 SetStringOpt(CURLOPT_POSTFIELDS, *(request.request()));

I have some wrappers around curl_easy_opt, pasted below.
At the end of the above line the value of success is true and
request.request()->length() is non-zero. request.request() points to
string whose lifetime is maintained until curl_easy_perform returns.

bool HttpConnection::SetStringOpt(CURLoption option, const string& value) {
  return SetCurlOpt(curl_handle_, option, value.c_str());
}

bool HttpConnection::SetBoolOpt(CURLoption option, bool value) {
  return SetCurlOpt(curl_handle_, option, static_cast<int64>(value));
}

bool HttpConnection::SetSizeOpt(CURLoption option, size_t value) {
  return SetCurlOpt(curl_handle_, option, static_cast<int64>(value));
}

template <typename Parameter>
static bool SetCurlOpt(CURL* handle,
                       CURLoption option,
                       const Parameter parameter) {
  if (!handle) {
    return false;
  }
  CURLcode rv = curl_easy_setopt(handle, option, parameter);
  if (rv) {
    LOG("libcurl error: %s.\n", Logger::WARN, curl_easy_strerror(rv));
  }
  return rv == CURLE_OK;
}
