1:你要注册一个开发者,创建应用,填写完基本信息之后就要填写回调地址了
2:选择右上角的管理控制台---选择左下角的 其他API -- 选择安全设置--授权回调页
3:测试代码
如下:
package main
import (
// 自己引包
)
type AccessToken struct {
AccessToken string `json:"access_token"`
ExpiresIn int `json:"expires_in"`
SessionSecret string `json:"session_secret"`
SessionKey string `json:"session_key"`
Scope string `json:"scope"`
}
type UserInfo struct {
UserId string `json:"userid"`
UserName string `json:"username"`
}
func main() {
r := mux.NewRouter()
r.HandleFunc("/listview", listView)
r.HandleFunc("/upload", upload)
r.HandleFunc("/down", down)
r.HandleFunc("/social/oauth/callback", index)
http.Handle("/", r)
err := http.ListenAndServe(":5555", nil)
if err != nil {
panic(err)
}
}
type User struct {
Name string
}
func listView(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
t, err := template.ParseFiles("./html/list.html")
if err != nil {
panic(err)
}
items := make([]*User, 0)
u1 := &User{"u1"}
u2 := &User{"u2"}
items = append(items, u1)
items = append(items, u2)
l := make(map[string]interface{})
images := []string{}
images = append(images, "A")
images = append(images, "B")
images = append(images, "C")
l["images"] = items
l["aaaa"] = images
t.Execute(w, l)
}
}
func index(w http.ResponseWriter, r *http.Request) {
code := r.FormValue("code")
item, err := getAccess_token(code, "自己的key", "自己的", "http://www.yingyutwo.com:5555/social/oauth/callback")
if err != nil {
fmt.Println("err="+err.Error())
return
}
userinfo, err := getUserInfo(item.AccessToken)
if err != nil {
fmt.Println("err="+err.Error())
return
}
fmt.Printf("item=%#v\n", userinfo)
fmt.Println("ok index")
}
//获取access——token
func getAccess_token(code, client_id, client_secret, redirect_uri string) (*AccessToken, error) {
url := "https://openapi.baidu.com/oauth/2.0/token?grant_type=authorization_code&code="+code+"&client_id="+client_id+"&client_secret="+client_secret+"&redirect_uri="+redirect_uri
resp, err := http.Get(url)
if err != nil {
return nil, err
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
return nil, err
}
accesstoken := &AccessToken{}
err = json.Unmarshal(body, accesstoken)
return accesstoken, err
}
//获取当前登录用户信息
func getUserInfo(access_token string) (*UserInfo, error) {

}
defer resp.Body.Close()

if err != nil {
return nil, err
}

err = json.Unmarshal(body, user)
return user, err
}
