I am trying to do a APIRest with the framework ECHO for the language GO , but I find the following difficulty, what I want is to make a request fetch with javascript , in where I send in the header of an invoice and its respective detail, the problem is that I do not know how to go through the data, my code is as follows:
HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title of the document</title>
</head>
<body>
<div id="msj"></div>
<script>
var detalles = [];
var detalle = {
Codigo : '123',
Descripcion : 'Azucar',
Cantidad : '1',
Valor : '5'
};
detalles.push(detalle);
var detalle = {
Codigo : '321',
Descripcion : 'Arroz',
Cantidad : '2',
Valor : '1'
};
detalles.push(detalle);
var datos ={
"Cliente" :'Andres',
"Direccion" :'Calle Falsa 123',
"Email" :'[email protected]',
"Detalles" : detalles,
}
var url1 = "http://localhost:1323/"
fetch(url1,
{
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
method: "POST",
body: JSON.stringify(datos)
})
.then(function(res){ return res.json(); })
.then(function(data){ document.getElementById("msj").innerHTML = JSON.stringify( data ); })
.catch(function(error) {
console.log('Hubo un problema con la petición Fetch:' + error);
});
</script>
</body>
</html>
CODE GO:
package main
import (
"net/http"
"github.com/labstack/echo"
"github.com/labstack/echo/middleware"
)
type Detalle struct {
Codigo string 'json:"codigo" form:"codigo" query:"codigo"'
Descripcion string 'json:"descripcion" form:"descripcion" query:"descripcion"'
Cantidad string 'json:"cantidad" form:"cantidad" query:"cantidad"'
Valor string 'json:"valor" form:"valor" query:"valor"'
}
type Factura struct {
Cliente string 'json:"cliente" form:"cliente" query:"cliente"'
Direccion string 'json:"direccion" form:"direccion" query:"direccion"'
Email string 'json:"email" form:"email" query:"email"'
Detalles []Detalle
}
func main() {
e := echo.New()
e.Use(middleware.CORSWithConfig(middleware.CORSConfig{
AllowOrigins: []string{"*"},
AllowMethods: []string{echo.GET, echo.PUT, echo.POST, echo.DELETE},
}))
e.GET("/", func(c echo.Context) error {
return c.String(http.StatusOK, "Hello, World!")
})
e.POST("/", save)
e.Logger.Fatal(e.Start(":1323"))
}
func save(c echo.Context) (err error) {
u := new(Factura)
if err = c.Bind(u); err != nil {
return c.String(http.StatusInternalServerError, "Error")
}
return c.JSON(http.StatusOK, u)
}
I am trying to guide me to the documentation but I still can not achieve it, the idea is to go through the detail to do the insertion in the BD.
