TP5 调用快递鸟api 查询快递信息

1，去快递鸟，下载sdk

https://www.kdniao.com/api-track 下载PHPsdk

2，下载下来的事PHP文件，不是以类的形式显示的，所以为了方便，我把他封装成了类，不需要封装成类的，直接下载官方的sdk

老规矩：

$appId   用户ID 

$appKey   API key 

这两个参数必须要有的

3，代码如下，注意返回的格式最好是json

class Apiexpress
{
    private $appId = '用户ID';

    private $appKey = 'API key';

    private $reqUrl = 'http://api.kdniao.com/Ebusiness/EbusinessOrderHandle.aspx';
    /**
     * Json方式 查询订单物流轨迹
     */
    function getOrderFind($GetCode,$GetName){
       $result =  $this->getOrderTracesByJson($GetName,$GetCode);
       return json_decode($result);
    }
    function getOrderTracesByJson($GetName,$GetCode){
        $requestData= "{'OrderCode':'','ShipperCode':'{$GetCode}','LogisticCode':'{$GetName}'}";

        $datas = array(
            'EBusinessID' => $this->appId,
            'RequestType' => '1002',
            'RequestData' => urlencode($requestData),
            'DataType' => '2',
        );
        $datas['DataSign'] = $this->encrypt($requestData, $this->appKey);
        $result=$this->sendPost($this->reqUrl, $datas);
        return $result;
    }

    /**
     *  post提交数据
     * @param  string $url 请求Url
     * @param  array $datas 提交的数据
     * @return url响应返回的html
     */
    function sendPost($url, $datas) {
        $temps = array();
        foreach ($datas as $key => $value) {
            $temps[] = sprintf('%s=%s', $key, $value);
        }
        $post_data = implode('&', $temps);
        $url_info = parse_url($url);
        if(empty($url_info['port']))
        {
            $url_info['port']=80;
        }
        $httpheader = "POST " . $url_info['path'] . " HTTP/1.0\r\n";
        $httpheader.= "Host:" . $url_info['host'] . "\r\n";
        $httpheader.= "Content-Type:application/x-www-form-urlencoded\r\n";
        $httpheader.= "Content-Length:" . strlen($post_data) . "\r\n";
        $httpheader.= "Connection:close\r\n\r\n";
        $httpheader.= $post_data;
        $fd = fsockopen($url_info['host'], $url_info['port']);
        fwrite($fd, $httpheader);
        $gets = "";
        $headerFlag = true;
        while (!feof($fd)) {
            if (($header = @fgets($fd)) && ($header == "\r\n" || $header == "\n")) {
                break;
            }
        }
        while (!feof($fd)) {
            $gets.= fread($fd, 128);
        }
        fclose($fd);

        return $gets;
    }

    /**
     * 电商Sign签名生成
     * @param data 内容
     * @param appkey Appkey
     * @return string
     */
    function encrypt($data, $appkey) {
        return urlencode(base64_encode(md5($data.$appkey)));
    }
