[英]Send data from c++ program to php web server
I have a php script running in a web server in order to perform some inserts into a database. 我在网络服务器上运行着一个php脚本,以便对数据库执行一些插入操作。 This script receives some encrypted data, decrypts it and push it into the db.
该脚本接收一些加密的数据,将其解密并将其推入数据库。
The responsible to send this data is a C++ program (Running in Linux), this program will send a message of no more than 40 characters every 5 seconds. 负责发送此数据的是一个C ++程序(在Linux中运行),该程序每5秒发送一次不超过40个字符的消息。
I was thinking on call some bash script that opens the URL ( http://myserver.com/myscript.php?message=adfafdadfasfasdfasdf ) and receives the message by argument. 我在考虑调用一些bash脚本来打开URL( http://myserver.com/myscript.php?message=adfafdadfasfasdfasdf )并通过参数接收消息。
I dont want a complex solution, because I just need to open the URL, it is a unidirectional communication channel. 我不需要复杂的解决方案,因为我只需要打开URL,它是一个单向通信通道。
Some simple solution to do this? 一些简单的解决方案可以做到这一点?
Thanks! 谢谢!
A more robust solution would be to use libcurl
, which lets you open a http connection in a few lines . 一个更可靠的解决方案是使用
libcurl
,它使您可以在几行中打开http连接 。 Here's the self contained example from the link: 这是链接中包含的示例:
#include <stdio.h>
#include <curl/curl.h>
int main(void)
{
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* example.com is redirected, so we tell libcurl to follow redirection */
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
/* 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);
}
return 0;
}
Since you don't need to parse the result of the HTTP query, you could just use system to call a standard utility like wget . 由于您不需要解析HTTP查询的结果,因此您可以使用system调用标准实用程序,如wget 。
int retVal = system("wget -O- -q http://whatever.com/foo/bar");
// handle return value as per the system man page
This is basically the same as what you were thinking about, save the script indirection. 基本上与您所想的相同,只是间接保存了脚本。
