Question

我收到此错误：

Object <object> has no method apply

调用此函数时

 var fb = new Facebook(Meteor.user().services.facebook.accessToken);
        data =Meteor.wrapAsync(fb.query("/search?q=" + keywords + "&type=page&fields=name,category,can_post,likes,link,location,emails,phone"));
on server side.

更新：尝试之后：

   var fb = new Facebook(Meteor.user().services.facebook.accessToken);
        var fbQuerySync = Meteor.wrapAsync(fb.query, fb);
        var data = fbQuerySync("/search?q=" + keywords + "&type=page&fields=name,category,can_post,likes,link,location,emails,phone");

我收到此错误

OUPS：该方法已经同步，这似乎是另一段代码：

Facebook.prototype.query = function(query, method) {
    var self = this;
    var method = (typeof method === 'undefined') ? 'get' : method;
    var data = Meteor.sync(function(done) {
        self.fb[method](query, function(err, res) {
            done(null, res);
        });
    });
    return data.result;
}

Answer 1

试试这个：

var fb = new Facebook(Meteor.user().services.facebook.accessToken);
var fbQuerySync = Meteor.wrapAsync(fb.query, fb);
var data = fbQuerySync("/search?q=" + keywords + "&type=page&fields=name,category,can_post,likes,link,location,emails,phone");

您的代码的问题在于您将错误的参数传递给Meteor.wrapAsync，如果要将传递的函数用作方法，则期望函数和最终上下文。

您获得的结果是可以在Meteor上下文中使用的同步函数。

调用wrapAsync时，object有方法适用
