用tp5写的接口

我用的是这个：https://market.aliyun.com/products/57002002/cmapi00035184.html?spm=5176.10695662.1996646101.searchclickresult.549c173dYGx2YO#sku=yuncode2918400001

public function chat()
    {
    	//tp获取请求的ip
        $ip = $_SERVER['REMOTE_ADDR'];
        //传入ip调用getAddress方法
        $address = $this->getAddress($ip);
        //将换算出来的地址返回给前端
		return json($address);
    }

//根据ip换算地址
 public function getAddress($ip)
 {
     $host = "https://ips.market.alicloudapi.com";
     $path = "/iplocaltion";
     $method = "GET";
     $appcode = "8d906c63c537482fb9e8f7e00f3c211a";//填写appcode
     $headers = array();
     array_push($headers, "Authorization:APPCODE " . $appcode);
     $querys = "ip=" . $ip;
     $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);

     //curl_setopt($curl, CURLOPT_HEADER, true);   如不输出json, 请打开这行代码，打印调试头部状态码。
     //状态码: 200 正常；400 URL无效；401 appCode错误； 403 次数用完； 500 API网管错误
     if (1 == strpos("$" . $host, "https://")) {
         curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
         curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
     }
     $out_put = curl_exec($curl);
     $out_put = json_decode($out_put, true);
     
//判断返回的code是否是100
     if ($out_put['code'] == '100') {
     	//返回的code是100就表示换算成功
         $out_put = $out_put['result'];
         //将换算出来的地址return出去
         return $out_put = $out_put['nation'] . $out_put['province'] . $out_put['city'] . $out_put['district'];
     } else {
     	//如果code不等于100说明没有换算成功
         return $out_put = '暂无定位';
     }

 }
