小编pzy*_*iak的帖子

我有这个代码：

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

int main()
{
    CURL *curl;
    CURLcode res;

    curl = curl_easy_init();

    if(curl)
    {
        curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
        curl_easy_setopt(curl, CURLOPT_URL, "localhost/rest-v1/devices/did1/tasks");
        curl_easy_setopt(curl,CURLOPT_PORT,22080);
        curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "{\"hello\" : \"darkness\"}");

        res = curl_easy_perform(curl);

    }

    curl_easy_cleanup(curl);
    return 0;
}

当我运行它时，我在控制台上得到这个打印：
