WeChat JSAPI require OAuth openid to submit a new order, use `$WeChat_Express->getAuthCode($callback)` to get an url for WeChat OAuth and `$WeChat_Express-->getOpenid($code)` in callback page to get openid.

## Example

p.s. the url for WeChat OAuth must be opened in WeChat In-App broswer, you can use `strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') === false` to check if the page were not opened in it, and generate a QR code for user.

All methods for WeChat OAuth will be removed in next stable version and I'll publish a WeChat MP library package for composer.
41+
The WeChat NATIVE payment gateway return a URI which can be opened within WeChat In-App broswer, you can generate a QR code with the URI.
42+
43+
```php
44+
$omnipay = Omnipay::create('Wechat_Express');
45+
46+
$omnipay->setAppId('app_id'); // App ID of your WeChat MP account
47+
$omnipay->setAppKey('app_key'); // App Key of your WeChat MP account
48+
$omnipay->setMchId('partner_id'); // Partner ID of your WeChat merchandiser (WeChat Pay) account
49+
50+
$params = array(
51+
'out_trade_no' => time() . rand(100, 999), // billing id in your system
52+
'notify_url' => $notify_url, // URL for asynchronous notify
53+
'body' => $billing_desc, // A simple description
54+
'total_fee' => 0.01, // Amount with less than 2 decimals places
55+
'fee_type' => 'CNY', // Currency name from ISO4217, Optional, default as CNY
56+
);
57+
58+
$response = $omnipay->purchase($params)->send();
59+
60+
$qrCode = new Endroid\QrCode\QrCode(); // Use Endroid\QrCode to generate the QR code
61+
$qrCode
62+
->setText($response->getRedirectUrl())
63+
->setSize(120)
64+
->setPadding(0)
65+
->render();

### Verify a payment (especially for asynchronous notify)

`completePurchase` for Omnipay-WeChat does not require the same arguments as when you made the initial `purchase` call. The only required parameter is `out_trade_no` (the billing id in your system) or `transaction_id` (the trade number from WeChat).
71+
72+
```php
73+
$omnipay = Omnipay::create('Wechat_Express');
74+
75+
$omnipay->setAppId('app_id'); // App ID of your WeChat MP account
76+
$omnipay->setAppKey('app_key'); // App Key of your WeChat MP account
77+
$omnipay->setMchId('partner_id'); // Partner ID of your WeChat merchandiser (WeChat Pay) account
78+
79+
$params = array(
80+
'out_trade_no' => $billing_id, // billing id in your system
81+
//or you can use 'transaction_id', the trade number from WeChat
82+
);
83+
84+
$response = $omnipay->completePurchase($params)->send();
85+
86+
if ($response->isSuccessful() && $response->isTradeStatusOk()) {
87+
$responseData = $response->getData();
88+
89+
// Do something here
