在数字化时代,电子邮件作为一种重要的相同东西,被广泛利用于团体跟商务范畴。C言语作为一种高效、机动的编程言语,在邮件编程范畴同样展示出其富强的才能。本文将深刻探究C言语邮件库的利用,帮助你轻松实现邮件的发送与接收,并控制高效编程技能。
C言语邮件库重要基于SMTP(简单邮件传输协定)跟POP3(邮局协定版本3)等协定,供给邮件发送跟接收的功能。罕见的C言语邮件库包含libcurl、libev、libevent等。
libcurl是一个基于C的库,支撑多种协定,包含HTTP、FTP、FTPS、SCP、SFTP、TFTP、LDAP、DICT、FILE、TELNET、IMAP、POP3、SMTP等。利用libcurl可能轻松实现邮件发送跟接收功能。
sudo apt-get install libcurl4-openssl-dev
#include <curl/curl.h>
int main(void) {
CURL *curl;
CURLcode res;
curl_global_init(CURL_GLOBAL_ALL);
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "smtp://smtp.example.com:25");
curl_easy_setopt(curl, CURLOPT_USERNAME, "username@example.com");
curl_easy_setopt(curl, CURLOPT_PASSWORD, "password");
curl_easy_setopt(curl, CURLOPT_FROM, "username@example.com");
curl_easy_setopt(curl, CURLOPT_TO, "recipient@example.com");
curl_easy_setopt(curl, CURLOPT_SUBJECT, "Subject");
curl_easy_setopt(curl, CURLOPT_MAIL_FROM, "username@example.com");
curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, "recipient@example.com");
curl_easy_setopt(curl, CURLOPT_READFUNCTION, NULL);
curl_easy_setopt(curl, CURLOPT_MAIL_FROM, "username@example.com");
curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, "recipient@example.com");
curl_easy_setopt(curl, CURLOPT_READDATA, "Hello, this is a test email!");
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
res = curl_easy_perform(curl);
if(res != CURLE_OK)
fprintf(stderr, "curl_easy_perform() failed: %s\n",
curl_easy_strerror(res));
curl_easy_cleanup(curl);
}
curl_global_cleanup();
return 0;
}
#include <curl/curl.h>
int main(void) {
CURL *curl;
CURLcode res;
curl_global_init(CURL_GLOBAL_ALL);
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "pop3://pop.example.com:110");
curl_easy_setopt(curl, CURLOPT_USERNAME, "username@example.com");
curl_easy_setopt(curl, CURLOPT_PASSWORD, "password");
curl_easy_setopt(curl, CURLOPT_MAIL_AUTH, "user");
curl_easy_setopt(curl, CURLOPT_READFUNCTION, NULL);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, NULL);
curl_easy_setopt(curl, CURLOPT_MAIL_FROM, "username@example.com");
curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, "username@example.com");
res = curl_easy_perform(curl);
if(res != CURLE_OK)
fprintf(stderr, "curl_easy_perform() failed: %s\n",
curl_easy_strerror(res));
curl_easy_cleanup(curl);
}
curl_global_cleanup();
return 0;
}
libev是一个变乱轮回库,可能用于编写高机能的并发顺序。利用libev可能轻松实现邮件发送跟接收功能。
sudo apt-get install libev-dev
