------解決方案--------------------
41001 缺少access_token參數

返回碼說明
------解決方案--------------------
$fp = fsockopen($url_info["host"], $url_info["port"]);
和
$request .= "POST ".$url_info['path']." HTTP/1.1\n";
$request .= "Host: ".$url_info['host']."\n";
$request .= "Content-type: application/x-www-form-urlencoded\n";
$request .= "Content-length: ".strlen($data)."\n";
$request .= "Connection: close\n";
$request .= "\n";
$request .= $data."\n";
裡沒有發現有token的資訊。

------解決方案--------------------
$request .= "POST ".$url_info['path']." HTTP/1.1\n";
這裡填寫帶路徑和參數的目標頁名稱，比如
/cgi-bin/qrcode/create?access_token=？？？？？
無論是 get 還是 post 方式，都是這樣寫
