我正在尝试通过此示例https://github.com/blackberry/BB10-WebWorks-Samples/blob/master/Twitter-OAuth-1/README.md
虽然，我不断收到以下错误：getAuthorization 中的错误：ReferenceError：找不到变量：facebookOptions
这是我的 javascript OAuth.js 代码
function initApp() {
try {
// facebook oauth setup
facebookOptions = {
clientId: '############',
clientSecret: '######################',
// we use a php script on a server because facebook doesn't allow for local:/// callbacks
// at this time. the php simply redirects us back to 'local:///index.html'
redirectUri: 'http://###########.com/redirect.php'
};
// here we check for query strings in window.location when the app loads. This is because facebook is calling back
// to our callbackUrl. When the app initializes, and there is a query string, it checks if the user
// authorized the app or not
var query = window.location.search;
authCode = null;
authCode = query.split('code=');
authCode = authCode[1] || null;
// we've got an auth code, let's exchange that for an access token
if (authCode !== null) {
getAccessToken();
}

我的网络服务器上的 php 重定向文件是这样的：
<?php
$queryString = $_SERVER['QUERY_STRING'];
header("location: local:///index.html" . $queryString);
?>
我不确定问题出在 oauth.js 中的授权还是在本地重定向 php 文件中。
