PHP 调用外部接口

//1.类中定义静态方法

class FtpService{

/**
 * 请求外网
 * @param $url  外网接口url
 * @param bool $params  参数，拼接字符串 post请求可以为数组
 * @param int $ispost  是否是post请求
 * @return array|bool
 */
public static function reqUrl($url, $params = false, $ispost = 0)
{
    $httpInfo = array();
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Data');
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 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);
    //echo $response;   //打印查看数据
    if ($response === FALSE) {
        return false;
    }

    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    $httpInfo = array_merge($httpInfo, curl_getinfo($ch));
    curl_close($ch);
    $response = json_decode($response,true);

    $result = [];
    $result['httpCode'] = $httpCode;
    $result['info'] = $response;
    return $result;
}

}

//2.调用eg: (例子为post请求，参数为数组或者拼接字符串)

//post调用 参数为数组
public function ApiTestPost() 
{
    $url = config('http_host')['interface'];   //配置外网接口
    $data = [
        'code'=>0,
        'sign'=>'1223435',  //校验签名，自己设置签名规则 外网校验
        'ordser_sn'=>'1234567'
    ];
    //$data = 'code=0&sign=12345&order_sn=1234567';   //也可以是这种格式
    $res = $this->reqUrl($url, $data,1);
    return $res['info']['data'];
}

//get调用  参数为拼接字符串

public function ApiTest()
{
    $url = config('http_host')['interface'];  //配置外网接口  $url = 'baidu.com'
    $order_sn = "987654321";
    $sign = '1234566';
    $params = "&appoint_sn=".$appoint_sn.'&sign='.$sign;
    $res = $this->reqUrl($url, $params);
    return $res['info']['data'];
}


//3.外网接口部分获取参数：
  post请求中：$data = input('');  //得到的就是上面$data数据  校验签名后写逻辑部分就ok了
　get请求中： $order_sn = input('order_sn');

 

$url = 'baidu.com'
