FB.ui Overview
FB.ui is a generic helper method for triggering Dialogs which allow the user to take some action.
These dialogs include:
- The Feed Dialog allows a user to post a story to their Timeline and to their friends' News Feeds
- The OAuth Dialog allows a user to authorize an application as part of an authentication flow.
- The Add Page Tab Dialog allows a user to add an application to a Facebook Page which they administer.
- The Friends Dialog allows a user to send a friend request to another user.
- The Pay Dialog allows a user to make a purchase using Facebook Credits.
- The Requests Dialog allows a user to send a request to one or more of their friends
- The Send Dialog allows a user to send a Facebook Message to one or more of their friends.
网页中中调出fb的支付页面，一般都是使用官方的 js SDK 操作。
简单的调用方法如下：
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="https://www.facebook.com/2008/fbml"> <head> <title>Facebook Credits Demo</title> </head> <body> <h2>Buy something...</h2> <button onclick="buy()">Buy</button> <div id="fb-ui-return-data"></div> <div id="fb-root"></div> <script src="http://connect.facebook.net/en_US/all.js"></script> <script>
// 这里初始化FB 的 SDK FB.init({appId: "YOUR_APP_ID", status: true, cookie: true}); // The dialog only opens if you've implemented the // Credits Callback payments_get_items. function buy() { var obj = { method: 'pay', action: 'buy_item', // You can pass any string, but your payments_get_items must // be able to process and respond to this data. order_info: {'item_id': '1a'}, // 这里是支付信息,这里的信息在支付中心与FB的支付协议中有 dev_purchase_params: {'oscif': true} };
// 调用 支付页面 FB.ui(obj, js_callback); }
// 反馈函数，作为调试用很好 // This JavaScript callback handles FB.ui's return data and differs // from the Credits Callbacks. var js_callback = function(data) { if (data['order_id']) { // Facebook only returns an order_id if you've implemented // the Credits Callback payments_status_update and settled // the user's placed order. // Notify the user that the purchased item has been delivered // without a complete reload of the game. write_callback_data( "<br><b>Transaction Completed!</b> </br></br>" + "Data returned from Facebook: </br>" + "Order ID: " + data['order_id'] + "</br>" + "Status: " + data['status']); } else if (data['error_code']) { // Appropriately alert the user. write_callback_data( "<br><b>Transaction Failed!</b> </br></br>" + "Error message returned from Facebook:</br>" + data['error_code'] + " - " + data['error_message']); } else { // Appropriately alert the user. write_callback_data("<br><b>Transaction failed!</b>"); } }; function write_callback_data(str) { document.getElementById('fb-ui-return-data').innerHTML=str; } </script> </body> </html>
下面这个是对应的url请求，
https://www.facebook.com/dialog/pay?app_id=YOUR_APP_ID&
redirect_uri=YOUR_REDIRECT_URI&
action=buy_item&
order_info={"item_id":"1a"}&
dev_purchase_params={"oscif":true}
// 这个url字符串写好后， 用urlencode() 编码一下
Properties

If {'oscif': true} is provided using the JavaScript SDK or {"oscif": true} is provided is provided using a direct URL, the Pay Dialog displays prices in local currency. If using the JavaScript SDK, the data format is a JavaScript object. If using a direct URL, the data format is a JSON string.
