Django 与 C++ 通信

Question

我需要将一些数据从客户端计算机中的 C++ 程序发送到 Django 服务器，以便使用 Python 处理数据并将其发送回另一台客户端计算机。如果它是 ajax 和 javascript 使用 json 之类的东西，那会很容易，但问题是，我研究了很多并找到了一个名为 Wt 的 C++ 库，它似乎有什么我需要，但我不知道如何将数据发送到 Django 视图。我找不到针对此问题的任何有用代码，如果有人能告诉我如何操作，我将不胜感激。

wt is a library for servers. You need a client. Your C++ code will act as the browser and make HTTP requests to your Django server. There are many C++ libraries that let you do that. A very common one is libcurl. It's easy to POST with libcurl as shown by their example:

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

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

  /* In windows, this will init the winsock stuff */ 
  curl_global_init(CURL_GLOBAL_ALL);

  /* get a curl handle */ 
  curl = curl_easy_init();
  if(curl) {
    /* First set the URL that is about to receive our POST. This URL can
       just as well be a https:// URL if that is what should receive the
       data. */ 
    curl_easy_setopt(curl, CURLOPT_URL, "http://my.django.server/some/url");
    /* Now specify the POST data */ 
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "name=daniel&project=curl");

    /* Perform the request, res will get the return code */ 
    res = curl_easy_perform(curl);
    /* Check for errors */ 
    if(res != CURLE_OK)
      fprintf(stderr, "curl_easy_perform() failed: %s\n",
              curl_easy_strerror(res));

    /* always cleanup */ 
    curl_easy_cleanup(curl);
  }
  curl_global_cleanup();
  return 0;
}
