4：golang，解决exec.Command().Run()命

解决办法：
把所用的命令写成一个string，然后用cmd /c 命令即可解决
eg:

context := "nc" + " 127.0.0.1 " + clinetPort + " >> " + path
cmd := exec.Command("cmd.exe", `/c`+context)
out, err := cmd.Output()

或者

dbDir = `C:/Users/zzz/Desktop/临时目录`
context := fmt.Sprintf("/c cd %s&%s&sqlite3.exe QQ.db < dump.sql", dbDir, dbDir[0:2])
cmd := exec.Command(`cmd.exe`, dmt)
