买股票的时候因为股份时时变动，所以卖出时机不好吃了好多亏，所以工作之余就想自己弄一个实时的接收自己想要的股份信息。
发送邮件用的smtp服务包，不多说了，直接上代码。
go_library项目的send_mail.go代码：
package gemailimport ("log""net/smtp""strings"
)//smtp服务发送邮件, mailType表示邮件格式是普通文件还是html或其他
func SendToMail(host, user, password, to, mailType, subject, body string) {hp := strings.Split(host, ":")auth := smtp.PlainAuth("", user, password, hp[0])content_type := "Content-Type: text/" + mailType + "; charset=UTF-8"msg := []byte("To: " + to + "\r\nFrom: " + user + "\r\nSubject: " + subject + "\r\n" + content_type + "\r\n\r\n" + body)send_to := strings.Split(to, ";")err := smtp.SendMail(host, auth, user, send_to, msg)if err != nil {log.Println("SendMail error: ", err)}
}
项目结构：
crawl_foundation.go代码：
package crawlimport ("go_library/gconvert""go_library/ghttp""log""math""strings""time"
)func ParseStr(hqStr string) []string {baseData := strings.Split(hqStr, "\"")base := strings.Split(baseData[1], ",")return base
}func Fetch_shsz(url string) string {client := ghttp.HttpClient(time.Second * 10)if client == nil {log.Println("get http client error")return ""}data := ghttp.HttpGet(client, url, "")base := ParseStr(data)str := gconvert.ConvertCharacterEncoding(base[0], "gb2312", "utf-8") + "\n"str += " 当前最新价：" + base[3] + " | 当前涨跌率："agoPrice := gconvert.StringToFloat64(base[2])nowPrice := gconvert.StringToFloat64(base[3])lv := ""if agoPrice > nowPrice {lv = "-"}upDown := math.Abs(nowPrice-agoPrice) / agoPrice * 100str += lv + gconvert.Float64ToString(upDown, 2) + "%\n"str += " 今日最高价：" + base[4] + " | 今日最低价：" + base[5] + "\n"str += " 今日开盘价：" + base[1] + " | 昨日收盘价：" + base[2] + "\n\n"return str
}func Fetch_CompositeIndex(url string) string {client := ghttp.HttpClient(time.Second * 10)if client == nil {log.Println("get http client error")return ""}data := ghttp.HttpGet(client, url, "")base := ParseStr(data)str := gconvert.ConvertCharacterEncoding(base[0], "gb2312", "utf-8") + " 当前指数：" + base[1] + " | 涨跌额：" + base[2] + " | 涨跌率：" + base[3] + "%\n\n"return str
}
