如何使用C发送电子邮件? [英] How can I send e-mail in C?

问题描述

我只是想知道如何使用C发送电子邮件?我用Google搜索了一下，但是找不到合适的东西.

I'm just wondering how can I send email using C? I Googled it a little bit, but could not find anything proper.

推荐答案

在类似Unix的系统上，您可以如下使用 system 和 sendmail :

On Unix like systems you can use system and sendmail as follows:

#include <stdio.h>
#include <string.h>

int main() {

        char cmd[100];  // to hold the command.
        char to[] = "[e-mail]"; // email id of the recepient.
        char body[] = "SO rocks";    // email body.
        char tempFile[100];     // name of tempfile.

        strcpy(tempFile,tempnam("/tmp","sendmail")); // generate temp file name.

        FILE *fp = fopen(tempFile,"w"); // open it for writing.
        fprintf(fp,"%s\n",body);        // write body to it.
        fclose(fp);             // close it.

        sprintf(cmd,"sendmail %s < %s",to,tempFile); // prepare command.
        system(cmd);     // execute it.

        return 0;
}

我知道它很丑，并且有几种更好的方法可以做到...但是它可以工作:)

I know its ugly and there are several better ways to do it...but it works :)
