[英]Marshall and UnMarshall JSON Content in GoLang
I have a sample json file which is structured like this 我有一个样本json文件,其结构如下
{
"method":"brute_force",
"bc":"select * from blah;",
"gc":[
"select sum(year) from blah;",
"select count(*) from table;"
]
}
I am trying to write a go program which can read this file and operate of json content. 我正在尝试编写一个可以读取此文件并运行json内容的go程序。
package main
import (
"fmt"
"encoding/json"
"io/ioutil"
)
type Response2 struct {
method string
bc string
gc []string
}
func main() {
file,_ := ioutil.ReadFile("config.json")
fmt.Printf("%s",string(file))
res := &Response2{}
json.Unmarshal([]byte(string(file)), &res)
fmt.Println(res)
fmt.Println(res.method)
fmt.Println(res.gc)
}
res.method and res.gc dont print anything. res.method和res.gc不打印任何东西。 I have no idea on whats going wrong.
我不知道什么是错的。
type Response2 struct {
method string
bc string
gc []string
}
The name of the fields Must be Uppercase otherwise the Json module can't access them (they are private to your module). 字段名称必须为大写,否则Json模块无法访问它们(它们对您的模块是私有的)。 You can use the json tag to specify a match between Field and name
您可以使用json标记指定Field和name之间的匹配项
type Response2 struct {
Method string `json:"method"`
Bc string `json:"bc"`
Gc []string `json:"gc"`
}
