Rwepay

微信支付 Wechat Pay Ruby SDK Gem

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

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。

Usage

JSPayment

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')

更新维权信息 [update_feedback]

options = { :access_token => access_token, :open_id => open_id, :feedback_id => feedback_id } js_payment.update_feedback(options)
