Typecho plug-in writing tutorial (6): Calling the interface, typecho plug-in

In this article we start to call the interface, we define a new method in the plug-in class, named send_post, In the method, we obtain the interface calling address through the system configuration.

The example given by Baidu uses php's CURL. For more advanced usage, you can learn the PHP_cURL initialization and execution method

Let’s combine the code provided by Baidu webmaster.

/**
   * 发送数据
   * @param $url 准备发送的url
   * @param $options 系统配置
   */
  public static function send_post($url, $options){
    //获取API
    $api = $options->plugin('BaiduSubmitTest')->api;

    //准备数据
    if( is_array($url) ){
      $urls = $url;
    }else{
      $urls = array($url);
    }

    $ch = curl_init();
    $options = array(
      CURLOPT_URL => $api,
      CURLOPT_POST => true,
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_POSTFIELDS => implode("\n", $urls),
      CURLOPT_HTTPHEADER => array('Content-Type: text/plain'),
    );
    curl_setopt_array($ch, $options);
    $result = curl_exec($ch);

    //记录日志
    file_put_contents('/tmp/send_log', date('H:i:s') . $result . "\n");
  }

Since we haven’t established a logging system yet, we will write the log to a file first and see the effect first!

Return value:
Copy code The code is as follows:
{"remain":48,"success":1}

Good! It seems there is no problem! However, to be on the safe side, I overridden this method using the http class that comes with typecho.

public static function send_post($url, $options){
    //获取API
    $api = $options->plugin('BaiduSubmitTest')->api;

    //准备数据
    if( is_array($url) ){
      $urls = $url;
    }else{
      $urls = array($url);
    }

    //为了保证成功调用，老高先做了判断
    if (false == Typecho_Http_Client::get()) {
      throw new Typecho_Plugin_Exception(_t('对不起, 您的主机不支持 php-curl 扩展而且没有打开 allow_url_fopen 功能, 无法正常使用此功能'));
    }

    //发送请求
    $http = Typecho_Http_Client::get();
    $http->setData(implode("\n", $urls));
    $http->setHeader('Content-Type','text/plain');
    $result = $http->send($api);

    //记录日志
    file_put_contents('/tmp/send_log', date('H:i:s') . $result . "\n");
  }
}

Copy after login

Now our plug-in can basically run, but the structure can be further optimized!
