Simple example of converting JSON data in Go language _golang

The go language converts JSON data is very simple.
Take the Easyui demo as an example to copy/demo/datagrid/datagrid_data1.json to the $GOPATH/SRC directory:

Json.go:

Copy Code code as follows:

Package Main

Import (
"Encoding/json"
"FMT"
"Io/ioutil"
)

Type product struct {
Productid string
Productname string
UnitCost float32
Status string
ListPrice float32
ATTR1 string
Itemid string
}

Type grid struct {
Total int
Rows []product
}

Func Main () {
var grid grid
Data, err: = Ioutil. ReadFile ("Datagrid_data1.json")
If Err!= nil {
Fmt. Println ("ReadFile:", err.) Error ())
}
Json. Unmarshal (data, &grid)
Fmt. Println (GRID)
Fmt. Println ("----------------------------")
B, _: = json. Marshal (GRID)
Fmt. Println (string (b))
}

Bind JSON to the struct body, and the field of the struct must be capitalized, otherwise the data cannot be bound.
