如何将结构数据放入go-lang的数据存储中

Question

how to put struct data in datastore in go-lang: //Struct is created.

type UserLogin struct{
    userName string
    passWord string
}
//values assigned

p1 := UserLogin{"poonam", "mumbai123"} p2 := UserLogin{passWord:"mumbai321", userName:"abcd"}

Now how to store/put/save and get above p1, p2 into datastore?

Answer 1

change struct to:

type UserLogin struct{
    UserName string
    PassWord string
}

needs to be public fields

storing:

c := appengine.NewContext(r)
p1 := UserLogin{"poonam", "mumbai123"}
key := datastore.NewKey(c, "UserLogin",p1.UserName, 0, nil)
datastore.Put(c, key,&p1)

reading:

c := appengine.NewContext(r)    
key := datastore.NewKey(c, "UserLogin", "", userName, nil)
var ul UserLogin
err := datastore.Get(c, key, &ul)

where r is the *http.Request also you need todo something with error,
