qq邮箱smtp设置
这里我用qq邮箱作为smtp服务器。开启smtp服务和获取qq授权码参照qq邮箱的官方说明，链接如下：帮助系统
源代码
//To use send Email for qq to port 465 (SSL)
#include <Arduino.h>
#if defined(ESP32)
#include <WiFi.h>
#elif defined(ESP8266)
#include <ESP8266WiFi.h>
#endif
#include <ESP_Mail_Client.h>
/* wifi ssid和密码 */
#define WIFI_SSID "xxx"
#define WIFI_PASSWORD "xxxx"
/* qq 邮箱的 smtp 地址和端口号 */
#define SMTP_HOST "smtp.qq.com"
#define SMTP_PORT 465
/*
你的邮箱和授权码 授权码是QQ邮箱推出的，用于登录第三方客户端的专用密码。

*/
#define AUTHOR_EMAIL "xxxx@qq.com"
#define AUTHOR_PASSWORD "xxxxxxx"
/* 接收人邮箱地址 email*/
#define RECIPIENT_EMAIL "xxxxx@qq.com"
/* 定义 smtp session 对象*/
SMTPSession smtp;
/* 获取邮件发送状态的回调函数 */
void getSmtpStatusCallback(SMTP_Status status);
void setup(){
Serial.begin(115200);
Serial.println();
Serial.print("连接 Wifi");
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
while (WiFi.status() != WL_CONNECTED){
Serial.print(".");
delay(200);
}
Serial.println("");
Serial.println("WiFi 连接成功.");
Serial.println("IP 地址: ");
Serial.println(WiFi.localIP());
Serial.println();
/* smtp开启debug，debug信息输出到串口 */
smtp.debug(1);
/* 注册回调函数，获取邮件发送状态 */
smtp.callback(getSmtpStatusCallback);
ESP_Mail_Session session;
/* 设置smtp 相关参数， host, port等 */
session.server.host_name = SMTP_HOST;
session.server.port = SMTP_PORT;
session.login.email = AUTHOR_EMAIL;
session.login.password = AUTHOR_PASSWORD;
session.login.user_domain = "";
/* 定义smtp message消息类 */
SMTP_Message message;
/* 定义邮件消息类的名称，发件人，标题和添加收件人 */
message.sender.name = "Esp8266er";
message.sender.email = AUTHOR_EMAIL;
message.subject = "Esp8266er Email";
message.addRecipient("Sara", RECIPIENT_EMAIL);
/* 设置message html 格式和内容*/
String htmlMsg = "<div style=\"color:#2f4468;\"><h1>Hello World!</h1><p>Sent from Esp8266er</p></div>";
message.html.content = htmlMsg.c_str();
message.html.content = htmlMsg.c_str();
message.text.charSet = "us-ascii";
message.html.transfer_encoding = Content_Transfer_Encoding::enc_7bit;
/* 连接smtp服务器 */
if (!smtp.connect(&session))
return;
/* 调用发送邮件函数，失败的话，获取失败信息 */
if (!MailClient.sendMail(&smtp, &message))
Serial.println("发送邮件失败，失败原因是 , " + smtp.errorReason());
}
void loop(){
}
/* 获取发送状态的回调函数 */
void getSmtpStatusCallback(SMTP_Status status){
/* 输出邮件发送状态信息 */
Serial.println(status.info());
/*状态获取成功，打印状态信息 */
if (status.success()){
Serial.println("----------------");
ESP_MAIL_PRINTF("邮件发送成功个数: %d\n", status.completedCount());
ESP_MAIL_PRINTF("邮件发送失败个数: %d\n", status.failedCount());
Serial.println("----------------\n");
struct tm dt;
for (size_t i = 0; i < smtp.sendingResult.size(); i++){
/* 依次获取发送邮件状态 */
SMTP_Result result = smtp.sendingResult.getItem(i);
time_t ts = (time_t)result.timestamp;
localtime_r(&ts, &dt);
ESP_MAIL_PRINTF("收件人: %s邮件发送状态信息\n", result.recipients);
ESP_MAIL_PRINTF("状态: %s\n", result.completed ? "success" : "failed");
ESP_MAIL_PRINTF("发送时间: %d/%d/%d %d:%d:%d\n", dt.tm_year + 1900, dt.tm_mon + 1, dt.tm_mday, dt.tm_hour, dt.tm_min, dt.tm_sec);
ESP_MAIL_PRINTF("邮件标题: %s\n", result.subject);
}
Serial.println("----------------\n");
}
}
串口输出
WiFi 连接成功.
