php中阿里云快递物流查询接口使用

官方给的php代码如下：

    $host = "https://ali-deliver.showapi.com";
    $path = "/showapi_expInfo";
    $method = "GET";
    $appcode = "你自己的AppCode";
    $headers = array();
    array_push($headers, "Authorization:APPCODE " . $appcode);
    $querys = "com=zhongtong&nu=535962308717&receiverPhone=receiverPhone&senderPhone=senderPhone";
    $bodys = "";
    $url = $host . $path . "?" . $querys;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_FAILONERROR, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_HEADER, true);
    if (1 == strpos("$".$host, "https://"))
    {
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    }
    var_dump(curl_exec($curl));

我写的代码如下：

// 查看物流信息接口
// $lo_num物流单号，$ename物流公司英文简写
public function see_wulius($lo_num,$ename){
    $host = "https://ali-deliver.showapi.com";
    $path = "/showapi_expInfo";
    $method = "GET";
    $appcode = "be817881f15540abd3015830f45318fd";
    $headers = array();
    array_push($headers, "Authorization:APPCODE " . $appcode);
    $querys = "com=".$ename."&nu=".$lo_num;
    $bodys = "";
    $url = $host . $path . "?" . $querys;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_FAILONERROR, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_HEADER, false);
    if (1 == strpos("$".$host, "https://")){
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    }
    curl_setopt($curl, CURLOPT_POSTFIELDS, $bodys);
    return (curl_exec($curl));
}

注意 curl_setopt($curl, CURLOPT_HEADER, false); 这里应该用false，不要包体头，这样才会返回json格式数据。如果按照官方给的文档这里是true的话，返回结果是字符串。

为了减少用户请求，我没有采用缓存，而是直接存入数据库，这样永久保留数据，什么时候都可以查看物流信息。每次查看物流的时候先判断该表有没有这个物流信息，没有就调接口查询然后存进来，有的话根据状态和过期时间判断是否需要重新请求接口，请求一次接口就更新一次数据，过期时间也更新。
