Json 如何使用Meteor 进行 API 调用

发布于01月15日

Ok here is the twitter API,

http://search.twitter.com/search.atom?q=perkytweets

谁能给我一些关于如何使用Meteor调用此API或链接的提示

Update::

下面是我try 的代码，但没有显示任何响应

if (Meteor.isClient) {
    Template.hello.greeting = function () {
        return "Welcome to HelloWorld";
    };

    Template.hello.events({
        'click input' : function () {
            checkTwitter();
        }
    });

    Meteor.methods({checkTwitter: function () {
        this.unblock();
        var result = Meteor.http.call("GET", "http://search.twitter.com/search.atom?q=perkytweets");
        alert(result.statusCode);
    }});
}

if (Meteor.isServer) {
    Meteor.startup(function () {
    });
}

推荐答案

You are defining your checkTwitter Meteor.method inside a client-scoped block. Because you cannot call cross domain from the client (unless using jsonp), you have to put this block in a Meteor.isServer block.

As an aside, per the documentation, the client side Meteor.method of your checkTwitter function is merely a stub of a server-side method. You'll want to check out the docs for a full explanation of how server-side and client-side Meteor.methods work together.

Here is a working example of the http call:

if (Meteor.isServer) {
    Meteor.methods({
        checkTwitter: function () {
            this.unblock();
            return Meteor.http.call("GET", "http://search.twitter.com/search.json?q=perkytweets");
        }
    });
}

//invoke the server method
if (Meteor.isClient) {
    Meteor.call("checkTwitter", function(error, results) {
        console.log(results.content); //results.data should be a JSON object
    });
}
