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

Introduction:
With the popularity of social networks and the development of tourism, social tourism has become a popular way of travel. As one of China's largest social network platforms, QQ's open interface provides a wealth of functions that can meet various needs for social travel. This article will introduce how to use PHP to connect to the QQ interface to realize the function of social tourism.

1. Preparation

1. Register as a QQ open platform developer, obtain AppID and AppKey
2. Download and install PHP SDK. You can download the latest version of PHP SDK from the official website of QQ Open Platform.
3. Create a QQ Internet development project and set the callback address. Create a new application in the developer center of the QQ open platform and set the callback address to the address of the PHP code we are about to write.

2. Download and install the SDK

1. Unzip the downloaded PHP SDK file and place it in the appropriate location on our web server.
2. Introduce the SDK file into our PHP code file. Add the following code to our actual code file to introduce the SDK:

require_once('path/to/qq_connect/comm/config.php');
require_once('path/to/qq_connect/comm/comm_fun.php');

3. Obtain Access Token

1. Guide the user to log in and obtain the Authorization Code

$request_url = $_SESSION['token_request_url'];
$redirect_uri = $_SESSION['redirect_uri'];
$state = $_SESSION['state'];

$authorize_url = "https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=".APPID."&redirect_uri={$redirect_uri}&state={$state}&scope=";
header("Location: $authorize_url");
exit();

2. Get Access Token

$request_url = $_SESSION['token_request_url'];
$authorization_code = $_REQUEST['code'];
$redirect_uri = $_SESSION['redirect_uri'];

$params = array(
    "grant_type" => "authorization_code",
    "client_id" => APPID,
    "client_secret" => APPKEY,
    "code" => $authorization_code,
    "redirect_uri" => $redirect_uri
);

$token_url = "https://graph.qq.com/oauth2.0/token";
$response = qq_get($token_url, $params);
$token = qq_format_str($response);
parse_str($token, $params);
$access_token = $params['access_token'];

4. Get user information

1. Get OpenID

$user_url = "https://graph.qq.com/oauth2.0/me?access_token=$access_token";
$response = qq_get($user_url);

$str_start = strpos($response, "(");
$str_end = strrpos($response, ")");
$str_len = $str_end-$str_start-1;
$json = substr($response, $str_start+1, $str_len);

$user_info = json_decode($json, true);  // 将获取到的用户信息转为数组
$openid = $user_info['openid'];

2. Obtain user details

$user_info_url = "https://graph.qq.com/user/get_user_info?access_token=$access_token";
$user_info = qq_get($user_info_url);
$user_info = json_decode($user_info, true);  // 将获取到的用户信息转为数组

5. Implement social tourism functions
According to the functions provided by the QQ interface, we can implement some social tourism functions, such as:

1. Create a travel plan
2. Join other users’ travel plans
3. Comment on other users’ travel plans

According to specific needs, you can use the corresponding functions of the QQ interface to complete it development.

Conclusion:
This article introduces how to use PHP to connect to the QQ interface to realize the function of social tourism. By registering as a QQ open platform developer, downloading and installing the PHP SDK, and obtaining Access Token and user information, we can realize various needs for social tourism. These functions can greatly enrich the social travel experience and provide users with better travel services.
