Performance optimization techniques for developing and implementing Baidu Wenxinyiyan API interface using PHP

Using PHP to develop and implement performance optimization techniques for Baidu Wenxin Yiyan API interface

With the popularity of the Internet, more and more developers are using third-party APIs Interface to obtain data to enrich your application content. Baidu Wenxin Yiyan API interface is a popular data interface. It can return a random inspirational, philosophical or warm sentence, which can be used to beautify the program interface, increase user experience, etc.

However, when using Baidu Wenxinyiyan API interface, we also face some performance considerations. The speed and efficiency of API calls directly affect the performance and user experience of our applications, so it is necessary for us to optimize them. Below, we will introduce several techniques for optimizing the performance of Baidu Wenxinyiyan API interface in PHP development.

1. Use cache
   Every time you request the Baidu Wenxin Yiyan API interface, a certain amount of time and network resources will be consumed. If we need to call this interface multiple times in a short period of time, it will reduce the performance of our application. Therefore, we can cache the data returned by the API to reduce the number of calls to the API.

Sample code:

function getOneWord() {
    $cache_file = 'one_word_cache.txt';
    // 判断缓存文件是否存在
    if (file_exists($cache_file) && time() - filemtime($cache_file) < 60 * 60 * 24) {
        // 如果缓存文件存在且未过期，则直接读取缓存文件内容
        $content = file_get_contents($cache_file);
    } else {
        // 调用API接口获取数据
        $url = 'http://api.hitokoto.cn/?encode=json';
        $content = file_get_contents($url);
        // 将数据保存到缓存文件
        file_put_contents($cache_file, $content);
    }
    return $content;
}

In the above sample code, we use a file as the cache file and the cache time is set to 1 day. If the cache file exists and has not expired, read the cache file content directly; otherwise, call the API interface again to obtain the data and save the data to the cache file.

2. Get multiple pieces of data in batches
   By default, the Baidu Wenxin Yiyan API interface returns a random statement each time. If we need to obtain multiple statements, we need to call the API multiple times, which increases the time overhead of the request. Therefore, we can reduce the number of API calls and improve application performance by obtaining multiple pieces of data in batches.

Sample code:

function getMultiWords($num) {
    $cache_file = 'multi_word_cache.txt';
    // 判断缓存文件是否存在
    if (file_exists($cache_file) && time() - filemtime($cache_file) < 60 * 60 * 24) {
        // 如果缓存文件存在且未过期，则直接读取缓存文件内容
        $content = file_get_contents($cache_file);
        $words = json_decode($content);
    } else {
        // 调用API接口获取数据
        $url = 'http://api.hitokoto.cn/?encode=json&c=' . $num;
        $content = file_get_contents($url);
        $words = json_decode($content);
        // 将数据保存到缓存文件
        file_put_contents($cache_file, json_encode($words));
    }
    return $words;
}

In the above sample code, we specify how many statements to obtain by adding a parameter c to the URL of the API interface. In the cache file, we save the returned data in JSON format.

3. Using concurrent requests
   When using the Baidu Wenxin Yiyan API interface, we can also increase the speed of data acquisition through concurrent requests. This can be achieved using PHP's multithreading extensions or coroutines.

Sample code:

function getOneWord() {
    $urls = [
        'http://api.hitokoto.cn/?encode=json',
        'http://api.hitokoto.cn/?encode=json',
        'http://api.hitokoto.cn/?encode=json',
    ];
    $curls = [];
    $result = [];
  
    // 初始化所有请求
    foreach ($urls as $i => $url) {
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curl, CURLOPT_ENCODING, 'gzip');
        $curls[$i] = $curl;
    }
  
    // 执行并发请求
    $mh = curl_multi_init();
    foreach ($curls as $i => $curl) {
        curl_multi_add_handle($mh, $curl);
    }
  
    // 同时执行多个请求
    do {
        curl_multi_exec($mh, $active);
    } while ($active > 0);
  
    // 获取响应结果
    foreach ($curls as $i => $curl) {
        $result[$i] = curl_multi_getcontent($curl);
        curl_multi_remove_handle($mh, $curl);
        curl_close($curl);
    }
    curl_multi_close($mh);
  
    return $result;
}

In the above sample code, we add the URLs we need to obtain to multi-threaded requests respectively, and obtain the response results of all requests through a loop.

The above are several performance optimization techniques for implementing Baidu Wenxin Yiyan API interface in PHP development. You can choose the appropriate method according to specific application scenarios to optimize API calling efficiency and improve application performance and user experience.
