我希望通过服务帐户获取Google Analytics的数据.当我第一次启动应用程序时,一切正常,我可以访问数据.但是,当我第二次启动应用程序时,出现以下错误:"系统找不到指定的路径".你有个主意吗？我以为它可以锁定.

            scope = scope,
            aud = "https://accounts.google.com/o/oauth2/token",
            iat = times[0],
            exp = times[1],
        };

        JavaScriptSerializer ser = new JavaScriptSerializer();

        // encoded header
        var headerSerialized = ser.Serialize(header);
