为什么JSON基本上是空的?
我正在玩Go并且难以理解为什么json编码和解码对我不起作用
我想我几乎逐字地复制了这些例子,但是输出结果表明编组和解组都没有返回任何数据.他们也没有给出错误.
任何人都可以暗示我哪里出错了?
我的示例代码:去游乐场
package main
import "fmt"
import "encoding/json"
type testStruct struct {
clip string `json:"clip"`
}
func main() {
//unmarshal test
var testJson = "{\"clip\":\"test\"}"
var t testStruct
var jsonData = []byte(testJson)
err := json.Unmarshal(jsonData, &t)
if err != nil {
fmt.Printf("There was an error decoding the json. err = %s", err)
return
}
fmt.Printf("contents of decoded json is: %#v\r\n", t)

t.clip = "test2"
data, err := json.Marshal(&t)
