php - 使用 API 将发票过帐到 XERO

Question

我正在尝试过帐 XERO 发票。这是函数

<?php
Function CallAPI($url, $method, $parameters, $options, &$response)
    {
    if (!IsSet($options['Resource'])) $options['Resource'] = 'API call';
    if (!IsSet($options['ConvertObjects'])) $options['ConvertObjects'] = false;
    $version = intval($this->oauth_version);
    $two_legged = ($version === 1 && IsSet($options['2Legged']) && $options['2Legged']);
    if (strlen($this->access_token) === 0 && !$two_legged)
        {
        if (!$this->RetrieveToken($valid)) return false;
        if (!$valid) return $this->SetError('the access token is not set to a valid value');
        }

    switch ($version)
        {
    case 1:
        if (!$two_legged && strlen($this->access_token_expiry) && strcmp($this->access_token_expiry, gmstrftime('%Y-%m-%d %H:%M:%S')) <= 0)
            {
            if (strlen($this->refresh_token) === 0) return ($this->SetError('the access token expired and no refresh token is available'));
            if ($this->debug) $this->OutputDebug('Refreshing the OAuth access token expired on ' . $this->access_token_expiry);
            $oauth = array(
                'oauth_token' => $this->access_token,
                'oauth_session_handle' => $this->refresh_token
            );
            if (!$this->ProcessToken1($oauth, $access_token)) return false;
            if (IsSet($options['FailOnAccessError']) && $options['FailOnAccessError'] && strlen($this->authorization_error))
                {
                $this->error = $this->authorization_error;
                return false;
                }

            if (!IsSet($access_token['authorized']) || !$access_token['authorized']) return ($this->SetError('failed to obtain a renewed the expired access token'));
            $this->access_token = $access_token['value'];
            $this->access_token_secret = $access_token['secret'];
            if (IsSet($access_token['refresh'])) $this->refresh_token = $access_token['refresh'];
            }

        $oauth = array();
        if (!$two_legged) $oauth[strlen($this->access_token_parameter) ? $this->access_token_parameter : 'oauth_token'] = $this->access_token;
        break;

    case 2:
        if (strlen($this->access_token_expiry) && strcmp($this->access_token_expiry, gmstrftime('%Y-%m-%d %H:%M:%S')) <= 0)
            {
            if (strlen($this->refresh_token) === 0) return ($this->SetError('the access token expired and no refresh token is available'));
            if ($this->debug) $this->OutputDebug('Refreshing the OAuth access token expired on ' . $this->access_token_expiry);
            if (!$this->ProcessToken2(null, true)) return false;
            if (IsSet($options['FailOnAccessError']) && $options['FailOnAccessError'] && strlen($this->authorization_error))
                {
                $this->error = $this->authorization_error;
                return false;
                }
            }

        $oauth = null;
        if (strcasecmp($this->access_token_type, 'Bearer')) $url.= (strcspn($url, '?') < strlen($url) ? '&' : '?') . (strlen($this->access_token_parameter) ? $this->access_token_parameter : 'access_token') . '=' . UrlEncode($this->access_token);
        break;

    default:
        return ($this->SetError($this->oauth_version . ' is not a supported version of the OAuth protocol'));
        }

    return ($this->SendAPIRequest($url, $method, $parameters, $oauth, $options, $response));
    }

我一直收到这个错误

我已成功连接到 Xero API，但我目前坚持使用 XML 发布发票。

<?php
$url = 'xml/invoice.xml';
$xml = simplexml_load_file($url);
$success3 = $client->CallAPI('https://api.xero.com/api.xro/2.0/Invoices', 'POST', array(
    'format' => 'text/xml',
    'File' => $xml
) , array(
    'FailOnAccessError' => true,
    'DecodeXMLResponse' => 'simplexml'
) , $user3);

这是我的代码，但我不确定这是否有效。这是我收到的错误响应。

SimpleXMLElement Object
(
[ErrorNumber] => 17
[Type] => NoDataProcessedException
[Message] => No data has been processed for this endpoint. This endpoint is expecting Invoice data to be specifed in the request body.
)

这是我使用的代码

Answer 1

将 'format' => 'text/xml' 更改为 format' => 'xml'。
