英文:
Golang: function return argument error
问题
以下代码给出了：
runtime.main: 调用外部函数 main.main
runtime.main: main.main: 未定义
runtime.main: 未定义: main.main
我弄错了返回参数，但是为什么？
请求：
fmt.Println(reflect.TypeOf(l))
返回 *ldap.Conn 作为类型
在不尝试返回对象的情况下，代码可以正常工作
package main
import (
"fmt"
"log"
"gopkg.in/ldap.v2"
)
var Ldap1 = "10.0.0.1"
var Lport1 = 389
var Prpl1 = "cn=admin,dc=Example,dc=com"
var Pass1 = "password"
func Bindldap(ldaphost string, port int, principal string, password string) *ldap.Conn {
l, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", ldaphost, port))
if err != nil {
log.Fatal(err)
}
defer l.Close()
err = l.Bind(principal, password)
if err != nil {
log.Fatal(err)
}
return l
}
func Main() {
a := Bindldap(Ldap1, Lport1, Prpl1, Pass1)
//对a进行一些操作
}
英文:
The following code gives:
runtime.main: call to external function main.main
runtime.main: main.main: not defined
runtime.main: undefined: main.main
I messed up with the return argument, but why?
Requesting:
fmt.Println( reflect.TypeOf(l))
gives *ldap.Conn as type
The code works without trying to return the object
package main
import (
"fmt"
"log"
"gopkg.in/ldap.v2"
)
var Ldap1 = "10.0.0.1"
var Lport1 = 389
var Prpl1 = "cn=admin,dc=Example,dc=com"
var Pass1 = "password"
func Bindldap(ldaphost string, port int, principal string, password string) *ldap.Conn {
l, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", ldaphost, port))
if err != nil {
log.Fatal(err)
}
defer l.Close()
err = l.Bind(principal, password)
if err != nil {
log.Fatal(err)
}
return l
}
func Main() {
a := Bindldap(Ldap1, Lport1, Prpl1, Pass1)
//do something with a
}

得分: 2
你的错误信息告诉你它正在寻找名为main的函数，而你在main包中调用了你的入口点Main（注意大写）。尝试使用以下代码：
func main() {
a := Bindldap(Ldap1, Lport1, Prpl1, Pass1)
//对a进行操作
}
英文:
You error messages are telling you it's looking for a function called main in your main package. You called your entry point Main (Note the caps). Try this:
func main() {
a := Bindldap(Ldap1, Lport1, Prpl1, Pass1)
//do something with a
}
