- bindator.BindBodies()
- bindator.BindParam()
- bindator.BindParams()
- bindator.BindUri()
- bindator.BindUris()
Example:
```go
package main
import (
"net/http"
"github.com/fanesz/bindator"
"github.com/gin-gonic/gin"
)
type User struct {
Email string `json:"email" validate:"required,email"`
Password string `json:"password" validate:"required"`
}
func main() {
router := gin.Default()
router.POST("/users", func(c *gin.Context) {
var user User
res := bindator.BindBody(c, &user)
if !res.Ok {
c.JSON(http.StatusBadRequest, res)
return
}
c.JSON(http.StatusOK, gin.H{
"email": user.Email,
"password": user.Password,
})
})
router.Run("127.0.0.1:8080")
}
```
### Fetch Result
#### When no body json provided:
```json
{
"message": "Invalid JSON data: unexpected end of JSON input"
}
```
#### When invalid body json:
```json
{
"message": "Invalid body type",
"errors": [
{
"field": "email",
"message": "Field is required"
},
{
"field": "password",
"message": "Field is required"
}
]
}
```
#### When invalid specific field (email, gte, lte, min, max, len):
```json
{
"message": "Invalid body type",
"errors": [
{
"field": "email",
"message": "Email is not valid"
}
]
}
```
## Embedded Binding and Validating
Used when you need to bind an embedded struct, for example:
```go
type Company struct {
User User `json:"user"`
Contract Contract `json:"contract"`
}
ok, res := bindator.BindBodies(c, &company)
```
note: you can't mix normal field with embedded field.
