Angular2与Json.parse（ - ）方法的问题

Question

请参阅以下有关“JSON.parse（ - ）”

的问题

  

错误   E：/ Arkin_Angular_Material_latestCode /阿肯布局/ src目录/应用/核心/服务/   http.service.ts（62,53）：类型'void |的参数任何[]'都不是   可分配给'string'类型的参数。类型'void'不是   可分配给'string'类型。

实际代码是

refreshToken.then(response => {
                         if(response != undefined){
                            const list = JSON.parse(response);
                            const userSession: UserSession = new UserSession();
                            userSession.accessToken = list.access_token;
                            userSession.tokenType = list.token_type;
                            userSession.refreshToken = list.refresh_token;
                            userSession.isLoggedin = true;
                            UserSessionManager.addUserSession(userSession);
                             console.log(response);
                             return super.get(fullUrl, this.requestOptions(options))
                             .catch(this.onCatch)
                             .do((res: Response) => {
                                 this.onSubscribeSuccess(res);
                             },(error: any) => {

试试这个：

userSession.accessToken = list.access_token as String;
userSession.tokenType = list.token_type as String;
userSession.refreshToken = list.refresh_token as String;
