My json looks like the following,
[
{
"key1": 1,
"key2": "val2"
},
{
"key1": 2,
"key2": "val2"
}
]
This json comes in string format and I want the objects in the json array to be inserted as individual records in mongodb. I referred to https://labix.org/mgo but wasn't able to find enough examples on the above use-case. Appreciate your thoughts in finding a solution.
Unmarshal the JSON to []interface{} and insert the result in the database. Assuming that c is an mgo.Collection and data is a []byte containing the JSON value, use the following code:
var v []interface{}
if err := json.Unmarshal(data, &v); err != nil {
// handle error
}
if err := c.Insert(v...); err != nil {
// handle error
}
In this example I will store the mixed array
test_string := '[[1,"a","b",2,"000000",[[1,2,3],[1,2,3]],"\"x","[y","'z",[[1,2,3],[1,2,3]]]]'
inside the mongodb as the json:
{datum: [[1,"a","b",2,"000000",[[1,2,3],[1,2,3]],"\"x","[y","'z",[[1,2,3],[1,2,3]]]]}
package main
import (
"strings"
"context"
"encoding/json"
"fmt"
"log"
"net/http"
"go.mongodb.org/mongo-driver/bson"
"go.mongodb.org/mongo-driver/bson/primitive"
)
type datum2 struct {
Datum interface{} `json:datum`
}
var userCollection = db().Database("goTest").Collection("users") // get collection "users" from db() which returns *mongo.Client
func typeinterface2mongo() {
var datum2 datum2_instance
var interfacevalue []interface{}
test_string := `[[1,"a","b",2,"000000",[[1,2,3],[1,2,3]],"\"x","[y","'z",[[1,2,3],[1,2,3]]]]`
if err := json.Unmarshal([]byte(test_string), &interfacevalue); err != nil {
fmt.Println(err)
return
}
fmt.Println(test_string)
fmt.Println(interfacevalue)
datum2_instance.Datum=interfacevalue
userCollection.InsertOne(context.TODO(), datum2_instance)
fmt.Println(datum2_instance)
fmt.Println(datum2_instance.Datum)
}
If you have json data already please follow from step 2.
If you have Xml data first you need to convert to the json format by using this package("github.com/basgys/goxml2json")
type JsonFileResponse struct {
JsonData string `bson:"JsonData " json:"JsonData"`
}
step 1: jsonData, err := xml2json.Convert(xml)
if err != nil {
panic("getting error while converting xml to json",err)
}
step 2: session need to open by using your mongodb credentials.
collection := session.DB("database name").C("Collection Name")
err = collection.Insert(JsonFileResponse{JsonData :json.String()})
if err != nil {
log.Fatal(err)
}
