Analysis of the implementation method of social food by connecting PHP to QQ interface

With the rapid development of social networks, food has become one of the important contents for people to share and communicate. As one of the largest social networks in China, QQ occupies an important position in the number of users. This article will introduce how to use PHP to connect to the QQ interface to realize the function of social food, and explain the specific implementation method step by step through sample code.

1. Apply for a QQ Internet developer account and application

First, we need to apply for a QQ Internet developer account and create a new application.

1. Visit the QQ Internet Developer Platform (https://connect.qq.com) and log in to your QQ account.

2. Click "Developer Center" on the left menu bar, and then click "Create New Application".

3. Fill in the application-related information, such as application name, application type, application introduction, etc., and submit the application.

4. After the application is successfully created, we can get the APP ID and APP Key. These two pieces of information will be useful in subsequent development.

2. PHP docking QQ login interface

1.Introducing QQ Internet SDK

First, we need to download the PHP SDK from the QQ Internet official website. After the download is complete, unzip the file and copy the corresponding folder to our project directory.

2. Create a login link

In our page, create a QQ login link. The link address is:

<a href="https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=<?php echo APP_ID;?>&redirect_uri=<?php echo urlencode(CALLBACK_URL);?>&state=<?php echo md5(uniqid(rand(), true));?>">使用QQ登录</a>

Among them, APP_ID and CALLBACK_URL are the APP ID and application callback URL we got when applying for the application respectively, and the state parameter is used to prevent CSRF attacks.

3. Processing of callback URL

In our callback URL file, we need to process the code parameter returned by the QQ login callback, and use the code to obtain access_token and openid, and then obtain user information .

Code example:

<?php
require_once "qq/API/qqConnectAPI.php";
$qc = new QC();
$access_token = $qc->qq_callback(); //获取access_token
$openid = $qc->get_openid(); //获取openid
//使用access_token和openid获取用户信息
$user_info = $qc->get_user_info(); 

//对获取的用户信息进行处理

?>

3. Implement social food function

After obtaining the user’s basic information, we can implement the social food function through the QQ interface. For example, we can realize interaction between users, users publish food information, etc.

Code example:

<?php
require_once "qq/API/qqConnectAPI.php";
$qc = new QC();
$access_token = $qc->qq_callback(); //获取access_token
$openid = $qc->get_openid(); //获取openid
//使用access_token和openid获取用户信息
$user_info = $qc->get_user_info(); 

//获取美食信息列表
$food_list = your_function_to_get_food_list($openid);

//显示美食信息列表
foreach($food_list as $food){
    echo $food['title']."<br>";
    echo $food['content']."<br>";
    echo $food['image']."<br>";
}

//用户发布美食信息
if(isset($_POST['submit'])){
    $title = $_POST['title'];
    $content = $_POST['content'];
    $image = $_FILES['image']['name'];

    //保存美食信息

    //显示保存成功信息
    echo "美食信息保存成功！";
}

?>

<form action="" method="POST" enctype="multipart/form-data">
    标题：<input type="text" name="title"><br>
    内容：<textarea name="content"></textarea><br>
    图片：<input type="file" name="image"><br>
    <input type="submit" name="submit" value="发布">
</form>

The above is an analysis of the method of using PHP to connect to the QQ interface to achieve social food. By applying for a QQ Internet developer account and application, introducing the QQ Internet SDK, and processing QQ login callbacks, we can implement the functions of QQ user login and obtaining user information. Through further expansion, we can use the QQ interface to implement more social food functions.
