Getting Started with GO
The content of this page might not be fully up-to-date with Strapi 5 yet.
This integration guide follows the Quick Start Guide and assumes you have you have fully completed the "Hands-on" path. You should be able to consume the API by browsing the URL http://localhost:1337/api/restaurants.
If you haven't gone through the Quick Start guide, the way you request a Strapi API with GO remains the same except that you do not fetch the same content.
Create a Go file
Be sure to have Go installed on your computer.
touch strapi.go
Go has built-in packages to make HTTP Requests like GET, POST, PUT, and DELETE. We will use the "net/http" package along with other packages.
GET Request your collection type
Execute a GET request on the restaurant collection type in order to fetch all your restaurants.
Be sure that you activated the find permission for the restaurant collection type.
response, error := http.Get("http://localhost:1337/api/restaurants")

Example
package main
import (
"fmt"
"io/ioutil"
"net/http"
)
func main() {
getD()
}
func getD() {
fmt.Println("Getting data...")
res, error := http.Get("http://localhost:1337/api/restaurants")
if error != nil {
fmt.Printf("The HTTP request failed with error %s\n", error)
} else {
data, _ := ioutil.ReadAll(res.Body)
fmt.Println(string(data))
}
}
POST Request your collection type
Execute a POST request on the restaurant collection type in order to create a restaurant.
Be sure that you activated the create permission for the restaurant collection type and the find permission for the category Collection type.
postRest, _ := json.Marshal(map[string]string{
"name": "Nwanyi Igbo",
"description": "This is a very nice place to eat native soup",
})
responseBody := bytes.NewBuffer(postRest)
resp, error := http.Post("http://localhost:1337/api/restaurants", "application/json", responseBody)
{
"id": 2,
"name": "Nwanyi Igbo",
"description": "This is a very nice place to eat native soup",
"created_at": "2021-03-04T09:57:11.669Z",
"updated_at": "2021-04-04T09:57:11.669Z",
"categories": []
}
Example
package main
import (
"bytes"
"encoding/json"
"fmt"
"io/ioutil"
"log"
"net/http"
)
func main() {
postD()
}
func getD() {
fmt.Println("Getting data...")
resp, error := http.Get("http://localhost:1337/api/restaurants")
if error != nil {
fmt.Printf("The HTTP request failed with error %s\n", error)
} else {
data, _ := ioutil.ReadAll(resp.Body)
fmt.Println(string(data))
}
}
func postD() {
fmt.Println("Posting data...")
//Encode the data
postRest, _ := json.Marshal(map[string]string{
"name": "Nwanyi Igbo",
"description": "This is a very nice place to eat native soup",
})
responseBody := bytes.NewBuffer(postRest)
resp, error := http.Post("http://localhost:1337/api/restaurants", "application/json", responseBody)
//Handle Error
if error != nil {
log.Fatalf("An Error Occurred %v", error)
}
defer resp.Body.Close()
//Read the response body
body, error := ioutil.ReadAll(resp.Body)
if error != nil {
log.Fatalln(error)
}
fmt.Println(string(body))
}
PUT Request your collection type
Execute a PUT request on the restaurant collection type in order to update the category of a restaurant.
Be sure that you activated the update permission for the restaurant collection type.
PUT Request is sligtly different as we need to target the particular thing we want update. We do this by first making a request to http://localhost:1337/api/restaurants/1 and then update what we want to update. In this example, we are going to update "Biscotte Restaurant" to "Restaurant Home".
putRest, _ := json.Marshal(map[string]string {
"name": "Restaurant Homes",
})
client := &http.Client{}
url := "http://localhost:1337/api/restaurants/1"
req, error := http.NewRequest(http.MethodPut, url, bytes.NewBuffer(putRest))
req.Header.Set("Content-Type", "application/json")
{
"id": 1,
"name": "Restaurant Homes",
"description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers.",
"published_at": "2021-03-07T10:10:46.949Z",
"created_at": "2021-03-07T10:08:53.929Z",
"updated_at": "2021-03-07T14:06:01.567Z",

"name": "French Food",
"published_at": "2021-03-07T10:09:43.232Z",
"created_at": "2021-03-07T10:09:34.135Z",
"updated_at": "2021-03-07T10:09:43.280Z"
},
{
"id": 2,

"published_at": "2021-03-07T10:10:19.608Z",
