Analysis of the implementation method of PHP docking QQ interface to implement social platform

In today's social media era, people increasingly rely on social platforms for communication and sharing. As one of the most popular social platforms in China, QQ has become a must-have feature for many websites and applications. This article will introduce how to use PHP to connect the QQ interface to implement the social platform, and give corresponding code examples.

1. Get a QQ Internet developer account

First of all, we need to apply for a QQ Internet developer account so that we can use QQ’s open interface. We can visit the official website of QQ Internet, click to apply for a developer account and follow the relevant steps to register.

2. Create an application

In the developer backend of QQ Internet, we can create a new application. In the process of creating an application, we need to fill in some relevant information, such as application name, website domain name, etc. After successful creation, we will get an App ID and App Key, these two parameters will be used in subsequent code.

3. Get the authorized URL

Before the user logs in, we need to obtain an authorized URL to guide the user to log in and obtain authorization. In PHP, we can get the authorized URL using the following code:

$appId = 'Your App ID';
$redirectUri = 'Your Redirect URL';
$scope = 'get_user_info,add_share';
$state = md5(uniqid(rand(), true));

$authUrl = "https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=".$appId."&redirect_uri=".$redirectUri."&scope=".$scope."&state=".$state;

In the above code, we need to replace Your App ID with the App ID we got in the second step , Your Redirect URL is replaced with our redirect URL, $scope corresponds to the permissions that need to be obtained, and $state is a randomly generated status code.

4. Get Access Token

After the user authorizes, the QQ server will redirect to our designated $redirectUri and bring an authorization code parameter. We can receive and process this authorization code on the redirected page and use it to obtain the Access Token. The following is a code example to obtain Access Token:

$appId = 'Your App ID';
$appKey = 'Your App Key';
$redirectUri = 'Your Redirect URL';
$code = $_GET['code'];

$tokenUrl = "https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&client_id=".$appId."&client_secret=".$appKey."&code=".$code."&redirect_uri=".$redirectUri;

$response = file_get_contents($tokenUrl);
if (strpos($response, "callback") !== false) {
    $lpos = strpos($response, "(");
    $rpos = strrpos($response, ")");
    $response  = substr($response, $lpos + 1, $rpos - $lpos -1);
    $msg = json_decode($response);
    if (isset($msg->error)) {
        echo "<h3>error:</h3>" . $msg->error;
        echo "<h3>msg  :</h3>" . $msg->error_description;
        exit;
    }
}

$params = array();
parse_str($response, $params);

$accessToken = $params['access_token'];

In the above code, we need to replace Your App ID with the App ID we obtained in the second step, Your Replace App Key with the App Key we obtained, and Your Redirect URL with our redirect URL.

5. Get the user's Open ID and other information

After obtaining the Access Token, we can use this Token to obtain the user's Open ID and other information. The following is a code example to obtain user information:

$openIdUrl = "https://graph.qq.com/oauth2.0/me?access_token=".$accessToken;

$response = file_get_contents($openIdUrl);
if (strpos($response, "callback") !== false) {
    $lpos = strpos($response, "(");
    $rpos = strrpos($response, ")");
    $response  = substr($response, $lpos + 1, $rpos - $lpos -1);
}

$userInfoUrl = "https://graph.qq.com/user/get_user_info?oauth_consumer_key=".$appId."&access_token=".$accessToken."&openid=".$response."&format=json";

$userInfoResponse = file_get_contents($userInfoUrl);
$userInfo = json_decode($userInfoResponse, true);

$openId = $userInfo['openid'];
$nickname = $userInfo['nickname'];
$avatar = $userInfo['figureurl_qq_2'];

In the above code, we use the Access Token and authorization code obtained previously to obtain the user's Open ID and other information by accessing the API provided by QQ.

Through the above steps, we can realize the function of using PHP to connect to the QQ interface to implement the social platform. Of course, the above code is just a simple example, and more processing and debugging may be required in actual projects.

Summary

This article introduces the implementation method of using PHP to connect the QQ interface to implement a social platform. By applying for a developer account, creating an application, obtaining the jump URL, obtaining the Access Token, and obtaining user information, we can complete the connection with the QQ interface and realize the functions of the social platform. I hope this article can provide some help for everyone to understand and use PHP to connect to the QQ interface.
