本文讲解了用GO实现OAuth2授权功能的调试方法，具体代码请参考工程文件，原理请参考另外2篇文章《OAuth 2.0 的四种方式》, 《OAuth2介绍与使用》。
2，工程下载和编译
加入辉哥区块链下载对应的工程文件。https://t.zsxq.com/EiyNbqB
3，凭证式(client_credentials)模式授权
3.1 创建文件
在gopkg.in\oauth2.v3\example\server的目录下创建 server2.go文件。
package main
import (
"log"
"net/http"
"gopkg.in/oauth2.v3/errors"
"gopkg.in/oauth2.v3/manage"
"gopkg.in/oauth2.v3/models"
"gopkg.in/oauth2.v3/server"
"gopkg.in/oauth2.v3/store"
)
func main() {
manager := manage.NewDefaultManager()
// token memory store
manager.MustTokenStorage(store.NewMemoryTokenStore())
// client memory store
clientStore := store.NewClientStore()
clientStore.Set("000000", &models.Client{
ID: "000000",
Secret: "999999",
Domain: "http://localhost",
})
manager.MapClientStorage(clientStore)
srv := server.NewDefaultServer(manager)
srv.SetAllowGetAccessRequest(true)
srv.SetClientInfoHandler(server.ClientFormHandler)
srv.SetInternalErrorHandler(func(err error) (re *errors.Response) {
log.Println("Internal Error:", err.Error())
return
})
srv.SetResponseErrorHandler(func(re *errors.Response) {
log.Println("Response Error:", re.Error.Error())
})
http.HandleFunc("/authorize", func(w http.ResponseWriter, r *http.Request) {
err := srv.HandleAuthorizeRequest(w, r)
if err != nil {
http.Error(w, err.Error(), http.StatusBadRequest)
}
})
http.HandleFunc("/token", func(w http.ResponseWriter, r *http.Request) {
srv.HandleTokenRequest(w, r)
})
log.Fatal(http.ListenAndServe(":9096", nil))
}
3.2 编译和运行
go build server2.go
./server2
3.3在本地浏览器打开
浏览器会返回JSON格式的ACCESS TOKEN授权码。
{
"access_token": "IPBCRFH4N7CHPKWSXDDAQW",
"expires_in": 7200,
"scope": "read",
"token_type": "Bearer"
}

4，完整四种授权方式代码
4.1 编译/运行授权服务器
进入GO 目录工程的gopkg.in\oauth2.v3\example\server下，编译运行OAUTH服务。
$ cd example/server
$ go build server.go
$ ./server
运行截图:
4.2 编译/运行客户端服务器
进入GO 目录工程的gopkg.in\oauth2.v3\example\client下，编译运行OAUTH服务。
$ cd example/client
$ go build client.go
$ ./client
运行截图:
4.3 授权码模式授权测试
4.3.1 浏览器打开
{
"access_token": eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJhdWQiOiIyMjIyMjIiLCJleHAiOjE1NTgwNzAxNTMsInN1YiI6IjAwMDAwMCJ9.RPDu6BkZ9_ZFUWqbMkNbcwMukt2NXbd9S9GAdhQ0ZVtV7qfeBslvOQLyfHKPVT30dFaUoRZFxuIXTQCotN6Sqw",
"token_type": "Bearer",
"refresh_token": "E_DW6S_EURIMCJ1NATXSJA",
"expiry": "2019-05-17T13:15:53.5879631+08:00""
}
运行截图：
4.3.2 使用access token
在浏览器输入 http://localhost:9094/try
有了ACCESS TOKEN，就可以直接打开客户端主页了，完成登录后的呈现。
{
"client_id": "222222",
"expires_in": 7195,
"user_id": "000000"
}
4.3.3 更新 access token
浏览器输入 http://localhost:9094/refresh
{
"access_token": "eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJhdWQiOiIyMjIyMjIiLCJleHAiOjE1NTgwNzAzNTMsInN1YiI6IjAwMDAwMCJ9._El-BI4GWjqcpjXXmFr5ClIYrIoWeLWSiaDCECSw-2tHhffvbzdt8p0DzD_LH9V1mDgkrDo894ZLDE3W1uM4vA",
"token_type": "Bearer",
"refresh_token": "ABZBEXS4XYOVHYYOLQYSUQ",
"expiry": "2019-05-17T13:19:13.9847635+08:00"
}
4.4 密码授权模式
浏览器输入 http://localhost:9094/pwd
{
"access_token": "eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJhdWQiOiIyMjIyMjIiLCJleHAiOjE1NTgwNzA0NTUsInN1YiI6InRlc3QifQ.X0ejwzSjzrWYz2Uoqm0jKkIo9hPcJvdDCW0spFmgCZyRzmgGWmKSjjNdUEfDVg4yM80zN0HJLmJRYhC4nG_mvQ",
"token_type": "Bearer",
"refresh_token": "YFKHVYGYVHSQKZ-9DKXVWW",
"expiry": "2019-05-17T13:20:55.3377359+08:00"
}
截图输出：
4.5 凭证式(Client Credentials)授权模式
浏览器输入 http://localhost:9094/client
{
"access_token": "eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJhdWQiOiIyMjIyMjIiLCJleHAiOjE1NTgwNzA4ODZ9.F4qFiGc3BDb8dY_kOFzkLHa775bF9EliI6a47DFNQnQ4rn_qE9i4tD7rsC7YDG6IcNXtXWCh8VvGaUlVYKTYjQ",
"token_type": "Bearer",
"expiry": "2019-05-17T13:28:06.817969+08:00"
}
