从服务品返回的token值 不在response中，是返回在响应头里的（respond.header）

第一步：获得服务器返回的数据

//获取长效令牌
      $appId="201804dfsfs200018";//应用APPID
      $appKey="qvedqG0fsfsqDei";

    $curl = curl_init();

    curl_setopt_array($curl, array(
      CURLOPT_URL => "https://api.yunhetong.com/api/auth/login",
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_ENCODING => "",
      CURLOPT_MAXREDIRS => 10,
      CURLOPT_TIMEOUT => 30,
                CURLOPT_SSL_VERIFYPEER => false,
                CURLOPT_SSL_VERIFYHOST => false,
          //CURLOPT_HEADER => true,
      CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
      CURLOPT_CUSTOMREQUEST => "POST",
      CURLOPT_POSTFIELDS => "{\n\"appId\":\"$appId\",\n\"appKey\":\"$appKey\"\n}",
      CURLOPT_HTTPHEADER => array(
      "cache-control: no-cache",
      "content-type: application/json",
      "postman-token: 5f1ca675-edb1-d414-b5da-cd967bd882ee"
      ),
    ));

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

    curl_close($curl);

    if ($err) {
      echo "cURL Error #:" . $err;
    } else {
      echo $response;

      
//      $arr = json_decode($response, true);
//      $code = $arr['code'];//code=200 说明成功
//      $msg = $arr['msg'];
//      //$token = $arr['token'];
//      echo $msg;
    }

返回这个值说明成功获取token值

第一步：获得token值  

是返回在响应头里的（respond.header），所以要输出header信息，然后取得token值  

完整代码：

//获取长效令牌
      $appId="20180454400018";//应用APPID
      $appKey="qverttrjqG0qDei";

    $curl = curl_init();

    curl_setopt_array($curl, array(
      CURLOPT_URL => "https://api.yunhetong.com/api/auth/login",
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_ENCODING => "",
      CURLOPT_MAXREDIRS => 10,
      CURLOPT_TIMEOUT => 30,
                CURLOPT_SSL_VERIFYPEER => false,
                CURLOPT_SSL_VERIFYHOST => false,
          CURLOPT_HEADER => true,
      CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
      CURLOPT_CUSTOMREQUEST => "POST",
      CURLOPT_POSTFIELDS => "{\n\"appId\":\"$appId\",\n\"appKey\":\"$appKey\"\n}",
      CURLOPT_HTTPHEADER => array(
      "cache-control: no-cache",
      "content-type: application/json",
      "postman-token: 5f1ca675-edb1-d414-b5da-cd967bd882ee"
      ),
    ));

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

    curl_close($curl);

    if ($err) {
      echo "cURL Error #:" . $err;
    } else {
      //echo $response;
        $headArr = explode("\r\n", $response);  
        foreach ($headArr as $loop) {  
          if(strpos($loop, "token") !== false){  
             $token = trim(substr($loop, 10));   
          }  
        }  
    }

print_r($token); 增加

要增加这段代码：

输出中包含header
