1，xml報文不用附加"<?xml version="1.0" encoding="UTF-8" ?>"，不支援，會報格式錯誤。

2，提交伺服器時要重點注意。

    直接使用curl方式的，一定要把資料做http_build_query，千萬不要直接放數組裡提交。

$params = array(
        'xml' => 'your xml',
        'verifyCode' => 'your verify code'
    );
$parambody =  http_build_query($params, '', '&');
curl_setopt($curl, CURLOPT_POSTFIELDS, $parambody);
 

$params = array(
        'xml' => 'your xml',
        'verifyCode' => 'your verify code'
    );
$response = $client->post(
        $uri,
        array(
            'form_params' => $params,
            'headers' => $header,
            'verify' => false
        )
    );
