beego 使用github.com/astaxie/beego/session异常问题

编写oauth controller代码：

package controllersimport ("encoding/json""fmt""errors""alertmanager/models""alertmanager/utils/oauth""github.com/astaxie/beego""github.com/astaxie/beego/orm""github.com/astaxie/beego/session"
)type OAuthController struct {BaseController
}var globalSessions *session.Managerfunc init() {sessionConfig := &session.ManagerConfig{CookieName:      "gosessionid",EnableSetCookie: true,Gclifetime:      3600,Maxlifetime:     3600,Secure:          false,CookieLifeTime:  3600,ProviderConfig:  "./tmp",}globalSessions, _ = session.NewManager("memory", sessionConfig)go globalSessions.GC()
}func (c *OAuthController ) OAuthUrl() {data := map[string]interface{}{"oauthUrl": oauth.GetOauthUrl()}c.HandleResult(&data)
}func (c *OAuthController ) Login() {code := c.GetString(":code")token, err := oauth.GetAccessToken(code)if err != nil {c.HandleError(err)}user, err := oauth.GetUserInfo(token.AccessToken)if err != nil {c.HandleError(err)}c.SetSession("user", user)data := map[string]interface{}{"user": user}c.HandleResult(&data)
}func (c *OAuthController ) Validate() {user := c.GetSession("user")if user == nil {err := fmt.Errorf("%s", "not login")c.HandleError(err)} else {data := map[string]interface{}{"user": user,}c.HandleResult(&data)}
}func (c *OAuthController ) Logout() {c.DelSession("user")c.HandleResult(nil)
}func (c *OAuthController ) NofityInsertUser() {b := c.Ctx.Input.RequestBodyvar user models.AlertUsererr := json.Unmarshal(b, &user)if err != nil {beego.Error(err)c.HandleError(err)return}// TODOo := orm.NewOrm()_, err = o.Insert(&user)if err != nil {beego.Error(err)c.HandleError(err)return}beego.Info(user)c.HandleResult(nil)
}func (c *OAuthController ) BackAdminLogin () {code := c.GetString(":admin")if code == "k8spaas" {var user oauth.Useruser.Name = "admin"user.Role.Name = "admin"c.SetSession("user", user)data := map[string]interface{}{"user": user}c.HandleResult(&data)return}var err_back error = errors.New("error admin password.")c.HandleError(err_back)
}

utils/oauth:

package oauthimport ("encoding/json""fmt""net/url""github.com/astaxie/beego""github.com/parnurzeal/gorequest"
)var (serverUrl         stringserverRedirectUrl stringauthorizePath     stringtokenPath         stringuserInfoPath      stringuserListPath      stringresponseType      stringscope             stringclientId          stringclientSecret      stringgrantType         stringredirectUri       stringoauthUrl          stringrawTokenUrl       stringuserInfoUrl       stringuserListUrl       string
)func init() {serverUrl = beego.AppConfig.String("oauth.server.server_url")serverRedirectUrl = beego.AppConfig.String("oauth.server.redirect_url")authorizePath = beego.AppConfig.String("oauth.path.authorize")tokenPath = beego.AppConfig.String("oauth.path.token")userInfoPath = beego.AppConfig.String("oauth.path.user.info")userListPath = beego.AppConfig.String("oauth.path.user.list")responseType = beego.AppConfig.String("oauth.response_type")scope = beego.AppConfig.String("oauth.scope")clientId = beego.AppConfig.String("oauth.client_id")clientSecret = beego.AppConfig.String("oauth.client_secret")grantType = beego.AppConfig.String("oauth.grant_type")redirectUri = beego.AppConfig.String("oauth.redirect_uri")oauthUrl = serverRedirectUrl + authorizePath +"?response_type=" + responseType +"&scope=" + scope +"&client_id=" + clientId +"&redirect_uri=" + url.QueryEscape(redirectUri)rawTokenUrl = serverUrl + tokenPath +"?client_id=" + clientId +"&client_secret=" + clientSecret +"&grant_type=" + grantType +"&redirect_uri=" + url.QueryEscape(redirectUri)userInfoUrl = serverUrl + userInfoPathuserListUrl = serverUrl + userListPath}func GetOauthUrl() string {return oauthUrl
}func GetUserInfo(accessToken string) (User, error) {beego.Info("oauth2.GetUserInfo begin.")request := gorequest.New()var user User_, body, errs := request.Get(userInfoUrl).Set("Authorization", "Bearer "+accessToken).End()if errs != nil {beego.Error(errs[0])return user, errs[0]}fmt.Println(body)err := json.Unmarshal([]byte(body), &user)return user, err
}func GetAccessToken(code string) (OauthAccessToken, error) {beego.Info("oauth2.GetAccessToken begin.")tokenUrl := GetTokenUrl(code)request := gorequest.New()var token OauthAccessToken_, body, errs := request.Post(tokenUrl).Set("Accept", "application/json").End()if errs != nil {beego.Error(errs[0])return token, errs[0]}fmt.Println(body)err := json.Unmarshal([]byte(body), &token)return token, err
}func GetTokenUrl(code string) string {return rawTokenUrl + "&code=" + code
}

types:

package oauthtype OauthAccessToken struct {AccessToken  string `json:"access_token"`TokenType    string `json:"token_type"`RefreshToken string `json:"refresh_token"`ExpiresIn    int    `json:"expires_in"`Scope        string `json:"scope"`
}type Role struct {Name string `json:"name"`
}type User struct {Id    int    `json:"id"`Name  string `json:"name"`Email string `json:"email"`Phone string `json:"phone"`Role  Role   `json:"role"`
}

配置文件：

sessionon = true
oauth.path.token = /oauth/token
oauth.path.authorize = /oauth/authorize
oauth.path.user.info = /user/info
oauth.path.user.list = /user/info/list
oauth.client_id= curl-client
oauth.client_secret= client-secret
oauth.grant_type= authorization_code
oauth.response_type= code
oauth.scope= read write[dev]oauth.server.server_url = http://oauth2.abc.sheincorp.cn
oauth.server.redirect_url = http://oauth2.abc.sheincorp.cn
oauth.redirect_uri = http://localhost:8082/#/OAuth

一定要设置sesstionon = true, 否则调用GetSession() SetSesstion() 方法会有异常。

异常如下：

Handler crashed with error runtime error: invalid memory address or nil pointer dereference
