此篇我们开始调用接口,我们在插件类中新定义一个方法,起名为send_post,在方法中我们通过系统配置获取接口调用地址。

百度给的例子中使用了php的CURL,更高级的使用方法可以学习PHP_cURL初始化和执行方法

下面我们结合一下百度站长提供的代码。

/**
   * 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");
  }

Copy after login

由于我们还没有建立日志系统,所以我们将日志先写入文件,先看效果吧!

返回值:

复制代码 代码如下:

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

Good!看来没有什么问题!不过为了保险起见,我还是用typecho自带的http类重写了此方法。

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

现在我们的插件基本能够运行了,但是在结构上还可以进一步优化!
