代码实现是比较简单的，主要是利用sns社区的开放api进行信息传输，系统是基于Linux，使用了libcurl进行网络部分的编程，而传感器是可以使用COM模拟。
#include <stdio.h>
#include <string.h>
#include "curl/curl.h"
#include "curl/types.h"
#include "curl/easy.h"
/* 针对sns 进行配置，可惜现在digu在维护中，可以自己选择配置 */
#define SNS_UPDATE_URL " http://api.digu.com/statuses/update.xml" /* sns 社区开放api入口 */
#define SNS_USERPWD "用户名:密码"
#define SNS_USER "用户email"
#define PROXY "可设置代理"
int digusendmsg(char *msg)
{
CURL *curl;
CURLcode res;
printf("Init to send message.\n");
struct curl_httppost *formpost=NULL;
struct curl_httppost *lastptr=NULL;
struct curl_slist *headerlist=NULL;
static const char buf[] = "Expect:";
curl_global_init(CURL_GLOBAL_ALL);
/*Fill in the file upload field */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME,"content",
CURLFORM_COPYCONTENTS, msg,
CURLFORM_END);
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME,"source",
CURLFORM_COPYCONTENTS,"mx",
CURLFORM_END);
curl = curl_easy_init();
printf("Init done!\n");
headerlist = curl_slist_append(headerlist, buf);
if(curl) {
/* what URL that receives this POST */
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(curl,CURLOPT_PROXY,PROXY);/* http代理设置,如果没有可以注释掉*/
curl_easy_setopt(curl,CURLOPT_URL,SNS_UPDATE_URL);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER,headerlist);
curl_easy_setopt(curl, CURLOPT_HTTPPOST,formpost);
curl_easy_setopt(curl, CURLOPT_HTTPAUTH,CURLAUTH_BASIC);
curl_easy_setopt(curl,CURLOPT_USERPWD,SNS_USERPWD);
curl_easy_setopt(curl, CURLOPT_HEADER, 1);
curl_easy_setopt(curl, CURLOPT_COOKIE,SNS_USER);
res = curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
/* then cleanup the formpost chain */
curl_formfree(formpost);
/* free slist */
curl_slist_free_all (headerlist);
if(!res){
printf("TranlateOK!\n");
return0;
}else{
printf("Tranlateerror!\n ");
return-1;
}
}
}
而从不同接口接受到的数据，就可以直接使用snsendmsg函数进行传输到SNS社区就可以了。
一个非常简单的应用J..
