Tutorial for writing typecho plug-in (VI): Calling interface

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

The example given by Baidu uses php's CURL, and more advanced usage methods can be learned.PHP_cURL initialization and execution methods

Let’s combine the code provided by Baidu webmaster.

/**
    * Send data
    * @param $url The url that is ready to be sent
    * @param $options System configuration
    */
  public static function send_post($url, $options){
    //Get API    $api = $options-&gt;plugin('BaiduSubmitTest')-&gt;api;

    //Prepare data    if( is_array($url) ){
      $urls = $url;
    }else{
      $urls = array($url);
    }

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

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

Since we have not established a log system, we will write the logs to the file first and see the effect first!

Return value:

Copy the codeThe code is as follows:

{"remain":48,"success":1}

Good! It seems that nothing is wrong! But to be on the safe side, I still rewrite this method with the http class that comes with typecho.

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

    //Prepare data    if( is_array($url) ){
      $urls = $url;
    }else{
      $urls = array($url);
    }

    //In order to ensure successful call, Lao Gao made a judgment first    if (false == Typecho_Http_Client::get()) {
      throw new Typecho_Plugin_Exception(_t('Sorry, your host does not support the php-curl extension and the allow_url_fopen function is not turned on, so this function cannot be used normally'));
    }

    //Send a request    $http = Typecho_Http_Client::get();
    $http-&gt;setData(implode("\n", $urls));
    $http-&gt;setHeader('Content-Type','text/plain');
    $result = $http-&gt;send($api);

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

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