SyntaxError：无法parsingJSON正文：意外的标记o
我在Facebook上有一个Node.js Heroku应用程序，并且我一直在日志中find以下错误（当我实际尝试访问我的应用程序时，遇到了一个通用的应用程序错误）：

另外令人困惑的是，如果我将JSON.stringify调用注释掉，我仍然会得到这个错误，所以任何想法都将非常感激！
根据https://github.com/heroku/faceplate/issues/26 ，我已经对我的代码进行了以下更改：
function handle_facebook_request(req, res) { // if the user is logged in if (req.facebook.token) { async.parallel([ function(cb) { // query 4 friends and send them to the socket for this socket id req.facebook.get('/me/friends', { limit: 4 }, function(friends) { req.friends = JSON.parse(JSON.stringify(friends)); cb(); }); }, function(cb) { // query 16 photos and send them to the socket for this socket id req.facebook.get('/me/photos', { limit: 16 }, function(photos) { req.photos = JSON.parse(JSON.stringify(photos)); cb(); }); }, function(cb) { // query 4 likes and send them to the socket for this socket id req.facebook.get('/me/likes', { limit: 4 }, function(likes) { req.likes = JSON.parse(JSON.stringify(likes)); cb(); }); }, function(cb) { // use fql to get a list of my friends that are using this app req.facebook.fql('SELECT uid, name, is_app_user, pic_square FROM user WHERE uid in (SELECT uid2 FROM friend WHERE uid1 = me()) AND is_app_user = 1', function(result) { req.friends_using_app = JSON.parse(JSON.stringify(result)); cb(); }); } ], function() { render_page(req, res); }); } else { render_page(req, res); } }
每一行与要求req.???? 例如req.friends就像req.friends = friends; 即我添加了JSON.parse和JSON.stringify调用，没有任何改变。
如前所述，解决scheme可以在这里find： https : //github.com/heroku/faceplate/issues/26但应该指出，现在有更多的细节修复面板版本0.0.4（感谢我的提示！）
