Facebook graph api 当我在客户端上执行Facebook.requestCredential时，如何在Meteor中获取凭据机密？

我正在尝试实现一个登录/链接帐户系统，如本文所述。
（向下滚动至显示“显式关联的方法”的位置）

您过去可以通过以下方式获取用户的登录数据：

data=Package.facebook.facebook.retrieveCredential（令牌）.serviceData

现在它看起来是这样的

retrieveCredential（令牌，秘密）

这是发生的地方

我一辈子都不知道如何在我呼叫后在服务器上获取凭据密码：

Package.facebook.Facebook.requestCredential(
    requestPermissions: Accounts.ui._options.requestPermissions["facebook"]
, (token) ->
    Meteor.call "userAddOauthCredentials", token, Meteor.userId(), service, (err, resp) ->
        if err?
            Meteor.userError.throwError(err.reason)
)

---

现在你可以这样做（在客户机上）：

然后在服务器上，您将需要该密码来访问用户的服务数据

userAddOAuthCredentials: (token, secret, service) ->
    services = Meteor.user().services
    serviceSearch = {}
    data = {}
    switch service
        when "facebook"
            if not services.facebook?
                data = Package.facebook.Facebook.retrieveCredential(token, secret)?.serviceData
                services.facebook = data
                serviceSearch = {"services.facebook.id": services.facebook.id}
            else
                throw new Meteor.Error(500, "You already have a linked Facebook account with email #{services.facebook.email}...")
    oldUser = Meteor.users.findOne(serviceSearch)
    if oldUser?
        throw new Meteor.Error(500, "Your #{service} account has already been assigned to another user.")

    Meteor.users.update(@userId, {$set: {services: services}})
    if data.email?
        if not _.contains(Meteor.user().emails, data.email)
            Meteor.users.update(@userId, {$push: {"emails": {address: data.email, verified: true}}})

这些函数将为您获取用户的服务数据，以便您可以链接多个帐户，或使用它们执行任何操作

userAddOAuthCredentials: (token, secret, service) ->
    services = Meteor.user().services
    serviceSearch = {}
    data = {}
    switch service
        when "facebook"
            if not services.facebook?
                data = Package.facebook.Facebook.retrieveCredential(token, secret)?.serviceData
                services.facebook = data
                serviceSearch = {"services.facebook.id": services.facebook.id}
            else
                throw new Meteor.Error(500, "You already have a linked Facebook account with email #{services.facebook.email}...")
    oldUser = Meteor.users.findOne(serviceSearch)
    if oldUser?
        throw new Meteor.Error(500, "Your #{service} account has already been assigned to another user.")

    Meteor.users.update(@userId, {$set: {services: services}})
    if data.email?
        if not _.contains(Meteor.user().emails, data.email)
            Meteor.users.update(@userId, {$push: {"emails": {address: data.email, verified: true}}})
