Codeigniter重定向后，多重卷曲将永远挂起。

Question

我正在使用codeigniter，然后在执行删除操作后重定向。 这是我要删除的脚本

if ($this->input->post('chkv')) {
                $id = $this->uri->segment(4); 
              $this->md_distributor->deletesite();
              redirect('admin/distributor/menulist/2/'.$id);

此控制器中有3个curl，这是我的curl请求

  function getROprovince()
   {

    $curl = curl_init();

        curl_setopt_array($curl, array(
          CURLOPT_URL => "https://pro.xxxxx.com/api/province",
          CURLOPT_RETURNTRANSFER => true,
          CURLOPT_ENCODING => "",
          CURLOPT_MAXREDIRS => 10,
          CURLOPT_TIMEOUT => 30,
          CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
          CURLOPT_CUSTOMREQUEST => "GET",
          CURLOPT_HTTPHEADER => array(
            "key: xxxxxxx"
          ),
        ));

        $response = curl_exec($curl);
        $err = curl_error($curl);

        curl_close($curl);

        if ($err) {
          echo "cURL Error #:" . $err;
        } else {
          return json_decode($response)->rajaongkir->results;

        }      



   }

第二次卷曲

function getROCity($province)
   {

    $curl = curl_init();

        curl_setopt_array($curl, array(
          CURLOPT_URL => "https://pro.xxxxx.com/api/city?province=".$province,
          CURLOPT_RETURNTRANSFER => true,
          CURLOPT_ENCODING => "",
          CURLOPT_MAXREDIRS => 10,
          CURLOPT_TIMEOUT => 30,
          CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
          CURLOPT_CUSTOMREQUEST => "GET",
          CURLOPT_HTTPHEADER => array(
            "key: xxxxx"
          ),
        ));

        $response = curl_exec($curl);
        $err = curl_error($curl);

        curl_close($curl);

        if ($err) {
          echo "cURL Error #:" . $err;
        } else {
          return json_decode($response)->rajaongkir->results;

        }      



   }

第三次卷曲

   function getROKec($city)
   {

    $curl = curl_init();

        curl_setopt_array($curl, array(
          CURLOPT_URL => "https://pro.xxxxx.com/api/subdistrict?city=".$city,
          CURLOPT_RETURNTRANSFER => true,
          CURLOPT_ENCODING => "",
          CURLOPT_MAXREDIRS => 10,
          CURLOPT_TIMEOUT => 30,
          CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
          CURLOPT_CUSTOMREQUEST => "GET",
          CURLOPT_HTTPHEADER => array(
            "key: xxxxxx"
          ),
        ));

        $response = curl_exec($curl);
        $err = curl_error($curl);

        curl_close($curl);

        if ($err) {
          echo "cURL Error #:" . $err;
        } else {
            //echo $response;
         return json_decode($response)->rajaongkir->results;

        }      



   }

如果仅使用location.href =没关系。 因为首先使用location.href加载而没有问题

但是当执行删除操作后，我使用重定向时，仅执行一次curl，并且它是随机的。

请告知。
