[Go] golang使用github里的imap类库

1.在windows系统下,需要首先定义两个环境变量GOPATH和GOROOT, GOPATH是第三方类库的代码目录 , GOROOT是go的安装目录

2.按照我的定义 , 进入这个目录D:\golang\code\src\github.com\emersion , 使用git 更新代码

git clone https://github.com/emersion/go-imap.git
git clone https://github.com/emersion/go-sasl.git

package main
 
import (
    "github.com/emersion/go-imap"
    "github.com/emersion/go-imap/client"
    "log"
)
 
const (
    server   = "imap.sina.net:993"
    username = "shihan@sopans.com"
    password = "xxxx"
)
 
func main() {
    var c *client.Client
    var err error
    log.Println("Connecting to server...")
    c, err = client.DialTLS(server, nil)
    //连接失败报错
    if err != nil {
        log.Fatal(err)
    }
    log.Println("Connected")
    //登陆
    if err := c.Login(username, password); err != nil {
        log.Fatal(err)
    }
    log.Println("Logged in")
    mailboxes := make(chan *imap.MailboxInfo, 20)
    go func() {
        c.List("", "*", mailboxes)
    }()
    //列取邮件夹
    for m := range mailboxes {
 
        mbox, err := c.Select(m.Name, false)
        if err != nil {
            log.Fatal(err)
        }
        to := mbox.Messages
        log.Printf("%s : %d", m.Name, to)
    }
}
