我使用google+api进行身份验证，并使用CodeIgniter框架检索用户数据。
身份验证后，在我在代码中指定的重定向uri的末尾添加一个随机字符串。
这将导致一个空白视图。我该怎么解决？
PS：同样的代码在本地主机上运行得非常好！

粗体部分被额外添加，导致一个空白视图。编辑：

您使用的是"普通"PHP URL，但CI有自己的URL格式siteURL.com/controller/function/param1/param2（默认情况下，您可以在config.PHP
$config['enable_query_strings'] = TRUE;中更改此格式）。签入更多信息：https://ellislab.com/codeigniter/user-guide/general/urls.html
如果您更改的url为：http://mgdevx.byethost14.com/blackjack/index.php/user_authentication/index/4/mjmogtOZrJxwHvR40vXdCEZ8tBgV-KWSUe8Nav6j-WA#
（没有?code=）部分，它重定向到所需的页面（我想，几乎不是空白的）。
然后，您应该捕获param并将其分配给$codevar。希望它能有所帮助！
更新
您应该更改：
public function index() {
至：
public function index($code == NULL) { //$code will 'catch' the param
然后进入：`
// Add Access Token to Session
if (isset($_GET['code'])) {`
更改为：
// Add Access Token to Session
if ($code != NULL) {
$client->authenticate($code);
然后，网址：http://mgdevx.byethost14.com/blackjack/index.php/user_authentication/index/4/mjmogtOZrJxwHvR40vXdCEZ8tBgV-KWSUe8Nav6j-WA#
将调用控制器user_authentication函数index（）和$code=4，如果您希望获得mjmog....-WA#部分，则必须在index（）函数中添加另一个参数，如：index($code==NULL,$api_key==NULL)
更新2:
好的。我想我们正处于起步阶段。我想你有URL问题。我进行注册，重定向返回一个"500服务器错误"，通常是URL配置错误。
？您是否在config.php中设置了enable_query_strings？：`$config['enable_query_string']=TRUE；
你有.htaccess文件吗？你能把它贴出来吗？
