How to implement version control and grayscale release of Baidu Wenxinyiyan API in PHP development?

Yiyan API is a simple interface provided by Baidu to obtain random chicken soup sentences, which is widely used in various applications. Version control and grayscale release are important means to ensure system stability and function upgrades. This article will introduce how to implement version control and grayscale release of Baidu Wenxinyiyan API in PHP development.

First of all, we need to integrate the SDK of Baidu Wenxin Yiyan API in the project. SDK dependencies can be introduced through Composer:

composer require 百度一言API的SDK

SDK will provide a series of API interfaces for us to call. We can create different version directories and configuration files in the project according to the requirements of version control and grayscale publishing. For example, we create the following directory structure:

|- src/
   |- v1/
      |- config.php
      |- Controller.php
   |- v2/
      |- config.php
      |- Controller.php
   |- Common.php

In each version of the config.php file, we can configure different API version numbers, API request addresses and other parameter information:

<?php
// v1/config.php
return [
    'version' => 'v1',
    'api_url' => 'http://api.baidu.com/v1',
    'api_key' => 'your_api_key_v1',
    'api_secret' => 'your_api_secret_v1',
];

// v2/config.php
return [
    'version' => 'v2',
    'api_url' => 'http://api.baidu.com/v2',
    'api_key' => 'your_api_key_v2',
    'api_secret' => 'your_api_secret_v2',
];

In each version In the Controller.php file of the version, we can implement the API interface calling logic of the corresponding version. The following is an example:

<?php
// v1/Controller.php
class Controller
{
    private $config;
    
    public function __construct()
    {
        $this->config = include 'config.php';
    }
    
    public function getOneWord()
    {
        $apiUrl = $this->config['api_url'] . '/word';
        $params = [
            'api_key' => $this->config['api_key'],
            'timestamp' => time(),
            'sign' => md5($this->config['api_secret'] . time()),
        ];
        
        // 发送请求并处理返回结果
        $result = apiRequest($apiUrl, $params);
        // ...
    }
}

// v2/Controller.php
class Controller
{
    private $config;
    
    public function __construct()
    {
        $this->config = include 'config.php';
    }
    
    public function getOneWord()
    {
        $apiUrl = $this->config['api_url'] . '/word';
        $params = [
            'api_key' => $this->config['api_key'],
            'timestamp' => time(),
            'sign' => md5($this->config['api_secret'] . time()),
            'extra_param' => 'value',
        ];
        
        // 发送请求并处理返回结果
        $result = apiRequest($apiUrl, $params);
        // ...
    }
}

// Common.php
function apiRequest($url, $params)
{
    // 发送HTTP请求并处理返回结果
    // ...
}

In the entry file of the project, we can choose to use different Controllers according to the version number:

<?php
$version = $_GET['version'];
$controllerFile = 'src/' . $version . '/Controller.php';
include $controllerFile;

$controller = new Controller();
$controller->getOneWord();

In this way, we can load different Controllers according to version control. Configuration files and Controller, and can flexibly call different versions of Baidu Wenxin Yiyan API interface.

For grayscale publishing, we can configure routing rules in Nginx or other reverse proxy servers to forward requests for specific versions to the corresponding backend server. Taking Nginx as an example, you can add the following rules to the configuration file:

location /one-word {
    if ($http_user_agent ~* V1-App) {
        proxy_pass http://backend-v1;
    }
    if ($http_user_agent ~* V2-App) {
        proxy_pass http://backend-v2;
    }
    # 其他版本规则...
}

Use the version number in the User-Agent header information to determine the requested version and forward the request to the corresponding back-end server.

To sum up, we can achieve flexible calling and upgrade management of Baidu Wenxinyiyan API in PHP development through version control and grayscale publishing. By configuring different version directories and files, as well as reasonably designed routing rules, we can easily cope with the needs and functional iterations of each version.
