php基于curl实现的股票信息查询类实例

本文实例讲述了php基于curl实现的股票信息查询类。分享给大家供大家参考，具体如下：

股票信息查询功能我们是需要抓取第三方的数据,然后我们再把这些数据进行分析组成自己想要的,下面我们来看一个php 股票信息查询类.

今天一个二逼朋友让我帮忙写个股票查询的类,来集成到微信中,所以花了一点时间写了一个不完整的,哈哈,如果有想玩的人,可以继续提交代码,让它变得完善起来！！

GitHub 地址:github.com/widuu/stock,代码如下:

class stock{
  /**
   * 股票数据接口
   */
  const STOCK_URL = "http://apis.baidu.com/apistore/stockservice/stock";
  /**
   * 通过拼音或者汉字获取股票代码
   */
  const SOCKET_SUGGEST = "http://cjhq.baidu.com/suggest?code5=";
  /**
   * 单态实例
   */
  private static $instance;
  /**
   * API 密钥
   */
  private static $apikey;
  /**
   * 实例化类和指定API KEY
   * @param apikey string
   * @return instance object
   */
  public static function getInstance($apikey){
    if( self::$instance == NULL ){
      self::$instance = new self;
      self::$apikey = $apikey;
    }
    return self::$instance;
  }
  /**
   * 获取股票名称
   * @param stockid  string
   * @return stockName string
   */
  public static function getName($stockid){
    $result = self::getSingleStock($stockid);
    return $result['name'];
  }
  /**
   * 获取最后更新时间
   * @param stockid string
   * @return time  string
   */
  public static function getTime($stockid){
    $result = self::getSingleStock($stockid);
    return $result['date'].$result['time'];
  }
  /**
   * 获取K线图地址
   * @param stockid string
   * @param date   string min/day/week/mouth
   * @return imageUrl string
   */
  public static function getKline($stockid,$date='min'){
    $result = self::getSingleStock($stockid);
    return $result['klinegraph'][$date.'url'];
  }
  /**
   * 抓取整只股票的数据
   * @param stockid string
   * @return stock infomation array
   */
  public static function getSingleStock($stockid){
    $type = preg_match('/(\d+){6}/is', $stockid);
    if ( $type == 0 ){
      $stockid = self::getStockId($stockid);
    }
    $stock_url = self::STOCK_URL."?stockid=".$stockid;
    $result = self::httpGet( $stock_url , true );
    if( $result['errNum'] != 0 ){
      throw new Exception($result['errMsg'], 1);
      return;
    }
    return $result['retData'];
  }
  /**
   * 输入拼音或者汉字来获取股票代码
   * @param name  string
   * @return stockid string
   */
  private static function getStockId($name){
    $result = self::httpGet( self::SOCKET_SUGGEST.urlencode(iconv('utf-8', 'GBK', $name)),false );
    if (emptyempty($result)){
      throw new Exception("stock name not exists", 2);
      return;
    }
    $stockid = $result['Result'][0]['code'];
    $stock  = explode('.', $stockid);
    return  $stock[1].$stock[0];
  }
  /**
   * GET获取方法
   * @param param string 参数
   * @author widuu
   */
  private static function httpGet($url,$header=false) {
    $curlHandle = curl_init();
    curl_setopt( $curlHandle , CURLOPT_URL, $url );
    if( $header ){
      curl_setopt( $curlHandle , CURLOPT_HTTPHEADER , array('apikey:'.self::$apikey));
    }
    curl_setopt( $curlHandle , CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt( $curlHandle , CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt( $curlHandle , CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt( $curlHandle , CURLOPT_TIMEOUT, 10 );
    $content = curl_exec( $curlHandle );
    curl_close( $curlHandle );
    return $header ? json_decode($content,true) :json_decode(iconv('GBK','utf-8',trim($content)),true);
  }
}
//测试代码
stock::getInstance("5040bcbfebb0a4cffc7be278723255aa");
print_r(stock::getSingleStock('sh601000'));
echo stock::getKline('紫金矿业');

希望本文所述对大家PHP程序设计有所帮助。
