Rwepay

微信支付 Wechat Pay Ruby SDK Gem

Ralipay(支付宝PaymentGem)姊妹篇，微信支付SDK

示例中的账号信息是微信提供的测试数据，你需要使用自己的账号信息才可以完成测试：）

注：测试期间（未上线状态）你需要在微信商户后台设定的域名下进行测试，测试域名只能在当前公众号会话内测试才有效，并且加好测试微信账号的白名单，否则JSAPI会报access_control:not_allow

具体参见微信API文档

特别要注意的一点，千万不要将微信提供的js demo使用在产品环境，那是非常不安全的。notify回调校验请严格使用notify_verify?方法进行。

Add this line to your application's Gemfile:

gem 'Rwepay'

And then execute:

$ bundle

Or install it yourself as:

$ gem install Rwepay

• 初始化 [new]

    configs = {
    	:app_id => 'wxf8b4f85f3a794e77',
    	:partner_id => '1900000109',
    	:app_key => 'xxxx',
    	:partner_key => '8934e7d15453e97507ef794cf7b0519d'
    }
    payment = Rwepay::JSPayment.new configs
  

• 创建支付请求 [get_brand_request] options参数用于构建package，示例中写了必填参数，可选参数也可使用hash方式传入，参见文档。

In Controller:

options = {
    :body => '测试商品',
    :notify_url => 'http://domain.com/to/path',
    :out_trade_no => 'TEST123456',
    :total_fee => '1',
    :spbill_create_ip => '127.0.0.1',
}
@brand_json = js_payment.get_brand_request(options)

In View:

<%= link_to '微信支付', "javascript:void(0)", :id => 'wechat'  %>
<script Language="javascript">
    document.addEventListener('WeixinJSBridgeReady', function onBridgeReady() {
    	$('#wechat').click(function(){
    		WeixinJSBridge.invoke('getBrandWCPayRequest', <%= raw @brand_json %>,function(res){
				if(res.err_msg == "get_brand_wcpay_request:ok" ) {
					alert('支付成功!');
				}else{
					alert(res.err_msg);
				}
			});
		});
	}, false);
</script>

• 回调验证 [notify_verify?]

    status = payment.notify_verify?(params)
    if status
    	#这里请自行验证params[:total_fee]的值与订单是否相符，按需要存储其他内容特别是transaction_id
    	render :text => 'success'
    else
    	render :text => 'fail'
    end
  

• 发货通知 [deliver_notify]

此接口调用需传入开放平台的access_token，由于access_token有时限且有请求限制，需要自行获取并按7200秒缓存，可使用下方的get_access_token方法

options = {
	:access_token => access_token,
	:open_id => 'oVGDVjni9uU30O9TGrlIWp-BcuYw',
	:trans_id => '1217737101201403308373364651',
	:out_trade_no => '1246154588',
	:deliver_timestamp => Time.now.to_i.to_s,
	:deliver_status => '1',
	:deliver_msg => 'ok'
}
status, error = js_payment.deliver_notify(options)

• 获取订单状态 [get_order_query]

    options = {
    	:access_token => access_token,
    	:out_trade_no => '1246154588'
    }
    status, response = js_payment.get_order_query(options)
  

• 获取access_token [get_access_token]

    access_token = js_payment.get_access_token('your app_secret hear')
