Question

我使用google + api进行身份验证并使用CodeIgniter框架检索用户数据。

在身份验证之后，在我在代码中指定的重定向uri的末尾添加了一个随机字符串。

这导致空白视图。我该如何解决这个问题？

PS：相同的代码在localhost上运行得非常好！

controller - user_authentication.php

<?php
// Start session

session_start();

class User_Authentication extends CI_Controller {

public function __construct() {
parent::__construct();
}

public function index() {

// Include two files from google-php-client library in controller
include_once APPPATH . "libraries/google-api-php-client-master/vendor/autoload.php";
include_once APPPATH . "libraries/google-api-php-client-master/src/Google/Client.php";
include_once APPPATH . "libraries/google-api-php-client-master/vendor/google/auth/src/OAuth2.php";

// Store values in variables from project created in Google Developer Console
$client_id = 'CLIENT ID';
$client_secret = 'SECRET';
$redirect_uri = 'http://mgdevx.byethost14.com/blackjack/index.php/user_authentication/index/';
$simple_api_key = 'KEY';

// Create Client Request to access Google API
$client = new Google_Client();
$client->setApplicationName("PHP Google OAuth Login Example");
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->setDeveloperKey($simple_api_key);
$client->addScope("https://www.googleapis.com/auth/userinfo.email");

// Send Client Request
$objOAuthService = new Google_Service_Oauth2($client);

// Add Access Token to Session
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['access_token'] = $client->getAccessToken();
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}

// Set Access Token to make Request
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
$client->setAccessToken($_SESSION['access_token']);
}

// Get User Data from Google and store them in $data
if ($client->getAccessToken()) {
$userData = $objOAuthService->userinfo->get();
$data['userData'] = $userData;
$_SESSION['access_token'] = $client->getAccessToken();
} else {
$authUrl = $client->createAuthUrl();
$data['authUrl'] = $authUrl;
}
// Load view and send values stored in $data
$this->load->view('google_authentication', $data);
}

// Unset session and logout
public function logout() {
unset($_SESSION['access_token']);
redirect(base_url());
}
}
?>

controller - main.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Main extends CI_Controller {

    public function index()
    {
        $this->load->view('main-page');
    }

    public function gregister()
    {
        $gmail = $this->session->userdata('email');
        $this->load->model('model_register');
        $value = $this->model_register->checkmail($gmail);
        if($value == 1)
        {
            $this->load->view('gregister');
        }
        else
        {
            $this->load->view('success-page');
        }   
    }     
}

对于一个帐户，重定向uri为：http://mgdevx.byethost14.com/blackjack/index.php/user_authentication/index/ ？code = 4 / mjmogtOZrJxwHvR40vXdCEZ8tBgV-KWSUe8Nav6j-WA＃

粗体部分会额外添加，导致空白视图。编辑：

Answer 1

您正在使用“普通”PHP网址，但CI有自己的网址格式siteURL.com/controller/function/param1/param2（默认情况下，您可以在config.php $config['enable_query_strings'] = TRUE;中更改此设置）。请访问：https://ellislab.com/codeigniter/user-guide/general/urls.html

如果您更改了http://mgdevx.byethost14.com/blackjack/index.php/user_authentication/index/4/mjmogtOZrJxwHvR40vXdCEZ8tBgV-KWSUe8Nav6j-WA#

的网址

（没有?code=）部分重定向到所需的页面（我猜，几乎不是空白）。

然后你应该抓住参数并分配给$ code var。希望它有所帮助！

更新

你应该改变：

public function index() {

到：

public function index($code == NULL) { //$code will 'catch' the param

然后在：`

// 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，网址为：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，如果你想得到mjmog....-WA#部分，你必须在index（）函数中添加另一个参数，如：{ {1}}

更新2：

确定。我猜我们正处于开始状态。我认为你有一个URL问题。我进行注册，重定向返回“500服务器错误”，通常是URL错误配置。

¿你在config.php中设置了enable_query_strings吗？： `$ config ['enable_query_strings'] = TRUE;

你有.htaccess文件吗？你能发贴吗？

google + api - 在重定向网址末尾添加了随机字符串
