今天遇到個玄學(xué)問題揖铜，用python3寫的pop接收yandex最新郵件可以正常使用膳音，但是java用的jodd-email開源庫寫的卻報證書問題。
Caused by: jodd.mail.MailException: Open session error; <--- sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at jodd.mail.MailSession.open(MailSession.java:86)
at jodd.mail.ReceiveMailSession.open(ReceiveMailSession.java:42)
at com.github.binarywang.demo.wx.mp.yandex.Ymail.<init>(Ymail.java:38)
at com.github.binarywang.demo.wx.mp.yandex.Ymail.<clinit>(Ymail.java:18)
掛上梯子后大审，問題消失蘸际，但速度奇慢。我按照yandex官方教程(https://yandex.com/support/mail/mail-clients.html)給windows安裝了證書徒扶，結(jié)果還是不行粮彤。更讓人感到不可思議的是，我電腦連的是手機(jī)無線網(wǎng)酷愧，結(jié)果手機(jī)上面卻顯示了證書已安裝驾诈。
下面是部分python代碼：
# -*- coding:utf-8 -*-
# @Time: 2018/8/10 14:49
# send email with yandex，使用接收郵件時需要在yandex設(shè)置中開啟要接收的folder
import smtplib
import poplib
from email.parser import Parser
import time
yandex_mail = "****"
yandex_pass = "****"
send_to_email = "****"
def send_emails(title, msg):
server = smtplib.SMTP_SSL('smtp.yandex.com', 465)
server.ehlo()
server.login(yandex_mail, yandex_pass)
message = 'Subject: {}\n\n{}'.format(title, msg)
server.sendmail(yandex_mail, send_to_email, message)
server.quit()
print('E-mails successfully sent!')
# indent用于縮進(jìn)顯示:
def get_email_content(message):
j = 0
content = ''
for part in message.walk():
j = j + 1
file_name = part.get_filename()
contentType = part.get_content_type()
if file_name: # 保存附件
pass
elif contentType == 'text/plain' or contentType == 'text/html':
data = part.get_payload(decode=True)
content = data.decode('utf-8', 'ignore')
# return str(content, 'utf-8')
return content
def get_server(usr, pwd, url="pop.yandex.com", port=995):
server = poplib.POP3_SSL(url, port)
server.user(yandex_mail)
server.pass_(yandex_pass)
return server
def get_msg(server, index):
resp, mails, octets = server.list()
# 可以查看返回的列表類似['1 82923', '2 2184', ...]
mails = [str(b, 'utf-8') for b in mails] # 將bytes的list轉(zhuǎn)為str的list
resp, lines, octets = server.retr(index)
# 獲得整個郵件的原始文本:
lines = [str(b, 'utf-8') for b in lines]
msg_content = "\n".join(list(map(str, lines)))
# 解析郵件:
msg = Parser().parsestr(msg_content)
return msg
def get_receive_time(msg):
rtime = msg.get('X-Yandex-TimeMark')
return int(rtime)
def get_from(msg):
mfrom = msg.get('From')
return mfrom
def receive_latest_email():
server = get_server(yandex_mail, yandex_pass)
# list()返回所有郵件的編號:
resp, mails, octets = server.list()
# print(mails)
# latest_index = len(mails)
latest_index = 1 # 經(jīng)測試溶浴，在yandex中最新郵箱始終為1
msg = get_msg(server, latest_index)
receive_time = int(get_receive_time(msg))
mfrom = get_from(msg)
content = get_email_content(msg)
print(content)
server.quit()
return receive_time, mfrom, content
# send_emails('Test Mail', 'Yes its a test mail!')
# print(receive_latest_email())
receive_latest_email()
下面是部分java代碼：
package com.github.binarywang.demo.wx.mp.yandex;
import jodd.mail.*;
import java.util.Date;
import java.util.List;
/***
* Time: 2018/8/12/15:20
* Description: yandex email
*/
public class Ymail {
private static final String USER = "****";
private static final String HOST = "pop.yandex.com";
private static final String PASSWD = "****";
private static final int POP_PORT = 995;
private ReceiveMailSession session = null;
private ReceivedEmail latestEmail = null;
private static Ymail ourInstance = new Ymail();
public static Ymail getInstance() {
return ourInstance;
}
private Ymail() {
if (this.session == null) {
Pop3Server server = MailServer.create()
.host(HOST)
.auth(USER, PASSWD)
.ssl(true)
.port(POP_PORT)
.buildPop3MailServer();
this.session = server.createSession();
session.open();
}
}
public void closeSession() {
if (this.session != null) {
this.session.close();
}
}
public String latestEmailContent() {
if (latestEmail == null) {
refresh();
}
List<EmailMessage> messages = this.latestEmail.messages();
StringBuilder sb = new StringBuilder();
for (EmailMessage msg : messages) {
sb.append(msg.getContent());
}
return sb.toString();
}
public Date latestEmailDate() {
if (latestEmail == null) {
refresh();
}
return latestEmail.receivedDate();
}
public String latestEmailFrom() {
if (latestEmail == null) {
refresh();
}
return latestEmail.from().getEmail();
}
public void refresh() {
ReceivedEmail[] emails = this.session.receiveEmailAndMarkSeen();
this.latestEmail = emails[0];
}
}
解決方法：
private Ymail() {
if (this.session == null) {
Pop3Server server = MailServer.create()
.host(HOST)
.auth(USER, PASSWD)
.ssl(true)
.port(POP_PORT)
.buildPop3MailServer();
server.getSessionProperties().put("mail.pop3.ssl.trust", "*");
this.session = server.createSession();
session.open();
}
}
還是google好使乍迄！
