API数据接口连接

如何接入API：

protected function http_request($url,$params=false,$ispost=0){
    try{
        $httpInfo = array();
        $ch = curl_init();

        curl_setopt( $ch, CURLOPT_HTTP_VERSION , CURL_HTTP_VERSION_1_1 );
        curl_setopt( $ch, CURLOPT_USERAGENT , 'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22' );
        curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT , 30 );
        curl_setopt( $ch, CURLOPT_TIMEOUT , 30);
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER , true );
        if( $ispost )
        {
            curl_setopt( $ch , CURLOPT_POST , true );
            curl_setopt( $ch , CURLOPT_POSTFIELDS , $params );
            curl_setopt( $ch , CURLOPT_URL , $url );
        }
        else
        {
            if($params){
                curl_setopt( $ch , CURLOPT_URL , $url.'?'.$params );
            }else{
                curl_setopt( $ch , CURLOPT_URL , $url);
            }
        }
        $response = curl_exec( $ch );

        $httpCode = curl_getinfo( $ch , CURLINFO_HTTP_CODE );
        $httpInfo = array_merge( $httpInfo , curl_getinfo( $ch ) );
        curl_close( $ch );
        return $response;
    }catch(Exception $e){
        return false;
    }
}

通过这个方法接入后，通过接入url地址获得自己想要的数据，

   public function history(){
       $url="http://apis.juhe.cn/lottery/history";//历史查询url地址
       $params["key"]="84b252036374157d238c097fb8ed1ef0";//key
       $params["lottery_id"]="ssq";//id为双色球
       $params["page_size"]=10;//默认条数是10条
       $param=http_build_query($params);
       $result = $this->http_request($url,$param);
       $res = json_decode($result,true);//返回的是整个json数据
//       dump($res);
//       dump($res['result']['lotteryResList']);die;
        $list = $res['result']['lotteryResList'];//根据dump出来的数据拆分['result']['lotteryResList']获得自己需要使用的二维数组
        $this->assign("list",$list);//注册变量list
        $this->show();//显示在页面
       
   }

上面是历史查询的url接口，根据请求参数说明，必填key   lottery_id参数设置号，获得的list；

res数组是

res下的lotteryResList数组如下是获得的二维数组；拿到前端页面循环遍历list数组
