使用 Go 将结构体数组插入到 Mongodb

Insert struct have array to Mongodb with Go

我想将如下数据结构插入到 MongoDB

{ "rolecode": "DHBK1_ROLE_04", "functioncodelist": [ "DHBK1_FUNC_1", "DHBK1_FUNC_2", ..... "DHBK1_FUNC_n"] "productid": "ABC_Platform", "comid": "DHBK1" }

这是我的代码:

package main
import (
    "context"
    "gopkg.in/mgo.v2"
)


func main() {
    insertObj()
}
type CompanyRoleFunction struct {
    Rolecode         string `json:"rolecode"`
    Productid        string `json:"productid"`
    Functioncodelist []string
    Comid string `json:"comid"`
}
func insertObj() {
    session, err := mgo.Dial("mongodb://casuser:Mellon@222.255.102.145:27017/users")
    if err != nil {
    panic(err)
    }
    c := session.DB("users").C("company_role_function")
    var companyRoleFunction CompanyRoleFunction
    companyRoleFunction.Rolecode = "DHBK1_ROLE_05"
    companyRoleFunction.Productid = "XYZ_Platform"
    companyRoleFunction.Comid = "DHBK1"
    err = c.Insert(companyRoleFunction)
    if err != nil {
        fmt.Println(err)
    }
}

我的代码有运行但它只插入这样的结构(当然,因为我不知道如何处理数组 Functioncodelist )

这是我的数据,希望能插入

{"_id":{"$oid":"5ed0c2e2402a000037004c84"},"rolecode":"DHBK1_ROLE_07","functioncodelist":["DHBK1_FUNC_1","DHBK1_FUNC_2"],"productid":"ABC_Platform","comid":"DHBK1"}

它没有出现在数据库中,因为您插入的文档不包含任何值。 在你的代码中设置一个值,它应该在数据库中显示得很好,除非我误解了你的问题。

...
type Functioncode string
...
companyRoleFunction.Functioncodelist = make(map[string]Functioncode)
...
companyRoleFunction.Functioncodelist["foo"] = "bar"
...
