Meteor Facebook使用签名请求登录

Question

我的应用使用Account-Facebook来处理Facebook登录。

我试图实现这种登录方式。 https://developers.facebook.com/docs/facebook-login/using-login-with-games#login

假设我有特定用户：

{
   "oauth_token": "{user-access-token}",
   "algorithm": "HMAC-SHA256",
   "expires": 1291840400,
   "issued_at": 1291836800,
   "user_id": "218471"
}

我怎样才能攻击Account-Facebook以像Meteor.loginWithFacebook那样登录用户呢？

Answer 1

以下是我的实施方式：

<强>的客户机/ landing.html上

<template name="landing"> 
        <a class="btn btn-lg btn-primary" id="login" role="button">Login with Facebook</a>
</template>

<强>的客户机/ landing.js

Template.landing.events({
    'click #login': function (e, tmpl) {
        console.log("Logging you in ");
        Meteor.loginWithFacebook({
            requestPermisssions: ['user']
        }, function(err){
            if(err){
                //handle errors
            }
            else{
                //show an alert
            }

       });
    } 
});

服务器/ accounts.js

Accounts.onCreateUser(function(option, user){
    var accessToken = user.services.facebook.accessToken;
    var result, profile;
    result = Meteor.http.get("https://graph.facebook.com/v2.2/me?fields=id,name,email,age_range",{
        params: {
            access_token: accessToken
        }       
    });

    if(result.error)
        throw result.error;

    fbData = _.pick(result.data,
        "name",
        "email",
        "age_range",
    )

    console.log(profile);
    return profile;
});

服务器/ config.js

ServiceConfiguration.configurations.remove({
    service: "facebook"
});

ServiceConfiguration.configurations.insert({
    service: "facebook",
    appId: "<your AppId>",
    secret: "<your App Secret>",
    loginStyle: "popup"
});
