我正在设置一个 meteor 应用程序，该应用程序涉及使用用户名和密码进行注册，然后希望将该帐户与 facebook 和 twitter 相关联。

我已经轻松启动并运行了第一部分，只需使用帐户包即可。但是当我有一个登录用户调用 Meteor.loginWithFacebook() 时，它会将他们注销并创建一个新帐户。我想要的是将 facebook 凭据添加到当前登录的用户。

meteor 文档有这个:

{
  _id: "bbca5d6a-2156-41c4-89da-0329e8c99a4f",  // Meteor.userId()
  username: "cool_kid_13", // unique name
  emails: [
    // each email address can only belong to one user.
    { address: "cool@example.com", verified: true },
    { address: "another@different.com", verified: false }
  ],
  createdAt: Wed Aug 21 2013 15:16:52 GMT-0700 (PDT),
  profile: {
    // The profile is writable by the user by default.
    name: "Joe Schmoe"
  },
  services: {
    facebook: {
      id: "709050", // facebook id
      accessToken: "AAACCgdX7G2...AbV9AZDZD"
    },
    resume: {
      loginTokens: [
        { token: "97e8c205-c7e4-47c9-9bea-8e2ccc0694cd",
          when: 1349761684048 }
      ]
    }
  }
}

这似乎是一个用户名也通过 Facebook 验证的帐户。但我不确定这是否只是您无法使用基本的 Meteor 东西实际实现的示例。

我想做的基本上是

Meteor.connectWithExternalAccount();

它运行与 Meteor.loginWithExternalAccount() 相同的过程，但只是将信息添加到当前登录的用户。

如果有人可以稍微解释一下 accounts-base 包，以便我自己知道从哪里开始，那就太好了。

此外，有人知道这是否会包含在 Meteor 的任何 future 版本中吗？

最佳答案

这是对我有用的代码(在服务器文件夹内):

Accounts.onCreateUser(function(options, user) {
    var email, oldUser, service;
    /*
    user.groups = {
        created: "",
        invited:"",
        RSVP:{
            coming:"",
            notComing:"",
            noReplay:""
        }
    };
    */
    if (user.profile == null) {
        user.profile = options.profile
    }
    if (user.services != null) {
        service = _.keys(user.services)[0];
        email = user.services[service].email;
        if (email != null) {
            oldUser = Meteor.users.findOne({
                "emails.address": email
            });
            if (oldUser != null) {
                if (oldUser.services == null) {
                    oldUser.services = {};
                }
                if (service === "google" || service === "facebook") {
                    oldUser.services[service] = user.services[service];
                    Meteor.users.remove(oldUser._id);
                    user = oldUser;
                }
            } else {
                if (service === "google" || service === "facebook") {
                    if (user.services[service].email != null) {
                        user.emails = [
                            {
                                address: user.services[service].email,
                                verified: true
                            }
                        ];
                    } else {
                        throw new Meteor.Error(500, "" + service + " account has no email attached");
                    }
                    user.profile.name = user.services[service].name;
                }
            }
        }
    }
    return user;
});

userAddOauthCredentials: function(token, userId, service) {
        var data, oldUser, selector, updateSelector;
        switch (service) {
            case "facebook":
                data = Facebook.retrieveCredential(token).serviceData;
                break;
            case "google":
                data = Google.retrieveCredential(token).serviceData;
        }
        selector = "services." + service + ".id";
        oldUser = Meteor.users.findOne({
            selector: data.id
        });
        if (oldUser != null) {
            throw new Meteor.Error(500, ("This " + service + " account has already") + "been assigned to another user.");
        }
        updateSelector = "services." + service;
        Meteor.users.update(userId, {
            $set: {
                updateSelector: data
            }
        });
        if (!_.contains(Meteor.user().emails, data.email)) {
            return Meteor.users.update(userId, {
                $push: {
                    "emails": {
                        address: data.email,
                        verified: true
                    }
                }
            });
        }
    }

在客户端 js 文件夹内:

var addUserService;

addUserService = function(service) {
    if (service === "email") {
} else {
    switch (service) {
        case "facebook":
            return Facebook.requestCredential({
                requestPermissions: ["email", "user_friends", "manage_notifications"]
            }, function(token) {
                return Meteor.call("userAddOauthCredentials", token, Meteor.userId(), service, function(err, resp) {
                    if (err != null) {
                        return Meteor.userError.throwError(err.reason);
                    }
                });
            });
        case "google":
            return Google.requestCredential({
                requestPermissions: ["email", "https://www.googleapis.com/auth/calendar"],
                requestOfflineToken: true
            }, function(token) {
                return Meteor.call("userAddOauthCredentials", token, Meteor.userId(), service, function(err, resp) {
                    if (err != null) {
                        return Meteor.userError.throwError(err.reason);
                    }
                });
            });
    }
}

};

模板事件中的相同 js 文件:

"click a": function(e) {
       var service;
        e.preventDefault();
        service = $(event.target).data("service");
        return addUserService(service);
    }

对于刚刚完成的 html:

<div class="social"><a id="fb" data-service="facebook"><img src="/../facebook.png"></a></div>
    <div class="social"><a id="go" data-service="google"><img src="/../googleplus.png"></a></div>

主要是你需要为你的服务设置数据服务，然后模板点击事件获取数据服务并执行addUserService(data-passed)。

希望它能奏效，请告诉我。
