一、项目简介
本项目主要实现的功能是ftp客户端不断地将xml文件和jpg文件实时地上传到服务器,当然也可以是其他格式的文件。每当ftp客户端取到一个文件之后,将文件上传到服务器后,然后将其删除。
项目实现可配置,如果开发者有类似的需求,只需要修改配置文件就可以使用本项目去完成上传文件的功能。
本项目打日志是按照当天时间来生成日志文件,每天每一种类型的日志只打一个文件。
二、项目结构图片
三、项目代码
config配置中的代码
config.ini
[path] xml_path = D:\\dian\\out\\ # xml文件所在的路径 img_path = D:\\dian\\out\\wave\\ # 图片文件所在路径 [ftp] ftpfile_path = D:\\Itudou # 在服务器上的文件存储路径 ftp_server_ip = 192.168.56.1 # ftp服务器的IP ftp_server_port = 21 # ftp服务器的端口 ftp_server_name = 20123762 # ftp服务器的用户名 ftp_server_pwd = 123456 # ftp服务器的密码 local_ip = 192.168.56.1 # 本地主机的IP local_port = 80 #本地主机端口 comm_way = udp #ftp的通信方式 [file] file_img =.jpg #文件后缀为img file_xml =.xml #文件后缀为xml log_print = ture #是否打日志,生产环境上不打日志,在调式程序的时候使用
读配置文件的代码
daos_config.go

ftp上传文件核心代码

打日志的代码
daos_log.go
package daoslog import ( "fmt" "log" "os" "github.com/golang/glog" "time" "bjdaos_tool/pkg/env" ) func WriteLog(islog, logtype , errcontent string) { if islog == "false" { return } if logtype != "Info" && logtype!= "Debug" && logtype!= "Error" && logtype != "System" { glog.Error("this is not a logtype ") return } data := time.Now().Format("20060102") logPath := env.GetConLogPath() logFilea := logPath + "\\" + data+"_"+ logtype+".log" errcontent = "[" +errcontent + "]" logFile, err := os.OpenFile(logFilea, os.O_RDWR | os.O_CREATE, 0777) if err != nil { fmt.Printf("open file error=%s\r\n", err.Error()) os.Exit(-1) } logger := log.New(logFile, "{"+logtype+"} ", log.Ldate | log.Ltime | log.Lshortfile) logger.Println(errcontent) }
路径处理代码
daos-evn.go
package env import ( "os" "runtime" ) var ostype = runtime.GOOS func GetProjectPath() string{ var projectPath string projectPath, _ = os.Getwd() return projectPath } func GetConfigPath() string{ path := GetProjectPath() if ostype == "windows"{ path = path + "\\" + "config\\" }else if ostype == "linux"{ path = path +"/" + "config/" } return path } func GetConLogPath() string{ path := GetProjectPath() if ostype == "windows"{ path = path + "\\log\\" }else if ostype == "linux"{ path = path + "/log/" } return path }
四、总结
主函数:
main.go
package main import ( "bjdaos_tool/pkg/daosftp" "bjdaos_tool/pkg/env" cfg "bjdaos_tool/pkg/daosconfig" ) func main(){ configPath := env.GetConfigPath() ftpConfig := new(cfg.Config) ftpConfig.InitConfig(configPath + "\\config.ini") xml_path := ftpConfig.Read("path", "xml_path") img_path := ftpConfig.Read("path", "img_path") file_img := ftpConfig.Read("file", "file_img") file_xml := ftpConfig.Read("file", "file_xml") for{ daosftp.SendXmlFileToFtpServer(xml_path, file_xml) daosftp.SendJpgFileToFtpServer(img_path, file_img) } }
