Analysis of the implementation method of connecting PHP to QQ interface to realize social shooting

With the rise of social media, people’s demand for sharing their lives is also increasing. Now, social photography has become a trend, and users can take photos with friends through social platforms. This article will introduce how to use PHP to connect to the QQ interface to realize the function of social shooting.

First, we need to register as a developer of the QQ open platform and create a new application. When creating an app, you need to obtain the App ID and App Key. This information will be used for authentication and API calls.

1. Obtain Access Token

Before making API calls, we need to obtain Access Token first to authenticate user identity. The following is a simple sample code:

<?php
$appId = 'your_app_id';
$appKey = 'your_app_key';
$callbackUrl = 'your_callback_url';

// 用户授权认证
function auth()
{
    global $appId, $callbackUrl;
    $scope = 'get_user_info,add_share';

    $authUrl = "https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id={$appId}&redirect_uri={$callbackUrl}&scope={$scope}";
    header("Location: {$authUrl}");
}

// 获取Access Token
function getAccessToken($code)
{
    global $appId, $appKey, $callbackUrl;

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

    $response = file_get_contents($tokenUrl);
    parse_str($response, $params);

    return $params['access_token'];
}

// 获取用户的OpenID
function getOpenId($accessToken)
{
    $openIdUrl = "https://graph.qq.com/oauth2.0/me?access_token={$accessToken}";

    $response = file_get_contents($openIdUrl);
    $pos = strpos($response, "(");
    $len = strpos($response, ")", $pos) - $pos;
    $json = substr($response, $pos + 1, $len - 1);

    $data = json_decode($json, true);

    return $data['openid'];
}

// 初始化
if (isset($_GET['code'])) {
    $accessToken = getAccessToken($_GET['code']);
    $openId = getOpenId($accessToken);

    // 在这里进行用户认证和业务逻辑处理
    // ...
} else {
    auth();
}
?>

In the above code, the auth() function is used for user authorization authentication and redirects the user to the QQ login page. getAccessToken($code) The function uses the authorization code to obtain the Access Token. getOpenId($accessToken) The function is used to obtain the user's OpenID.

2. Take photos and share them

After completing user authentication, we can use the QQ interface to take photos and share them. The following is a sample code:

<?php
function takePhoto($accessToken, $openId, $title, $photoUrl)
{
    $addShareUrl = "https://graph.qq.com/photo/add_share";

    $params = [
        'access_token' => $accessToken,
        'oauth_consumer_key' => 'your_app_id',
        'openid' => $openId,
        'format' => 'json',
        'title' => $title,
        'url' => $photoUrl
    ];

    $response = json_decode(http('POST', $addShareUrl, $params), true);

    if ($response['ret'] !== 0) {
        // 处理错误逻辑
    } else {
        // 分享成功后的逻辑处理
    }
}
?>

In the sample code, the takePhoto($accessToken, $openId, $title, $photoUrl) function is used to take photos and share them. Among them, $accessToken is the Access Token obtained, $openId is the user's OpenID, $title is the title of the photo, $photoUrl is the URL address of the photo.

In actual use, we can modify and expand the code according to business needs. For example, you can add image compression, photo editing and other functions.

Summary

Through the above sample code, we can see that it is not complicated to use PHP to connect to the QQ interface to realize the social shooting function. Just complete user authentication, obtain Access Token, and then take photos and share them according to business needs. I hope this article will help you understand how to use PHP to connect to the QQ interface to achieve social shooting.
