Question

使用带有coffeescript的Facebook API时遇到问题。每次我FB.getLoginStatus且状态为"connected"时，我都会自动调用FB.api("/me", (data)->console.log(data))页面，而不会让我自动重新加载。

另一个问题是，如果在console.log电话后放置一个断点并且注意数据的价值，则会从Facebook收到错误。

我想知道我是否这样做，以及为什么页面重新加载。

以下是该页面的coffeescript代码：

window.fbAsyncInit = ->
  FB.init
    appId: document.getElementById("fb-root").getAttribute("data-app-id")
    channelUrl: document.getElementById("fb-root").getAttribute("data-channel-url")
    status: true,
    cookie: true,
    xfbml: true

  FB.Event.subscribe('auth.login', (response) ->
    window.location = window.location
  )
  FB.Canvas.setAutoGrow()
  FB.getLoginStatus((data) ->
     console.log(data)
     if (data.status == "connected")
      uid = data.authResponse.userID
      accessToken = data.authResponse.accessToken;
      FB.api("/me", (data) ->
        console.log(data) // Here is the last call before the reload
      )
     else if (data.status == "not_authorized")
        console.log("Je suis log a facebook")
        $("#FBConnect").on("click", (e) ->
            FB.login( (response) ->
              if response.authResponse
                console.log('Welcome!  Fetching your information.... ');
                FB.api('/me', (response) ->
                  console.log('Good to see you, ' + response.name + '.');
                )
              else
                console.log('User cancelled login or did not fully authorize.');
            )
        )
      # the user is logged in to Facebook,
      # but has not authenticated your app
     else
        console.log("Je ne suis pas connecte a facebook")
      # the user isn't logged in to Facebook.
  )

PageScript = document.getElementsByTagName("script")[0]
return if document.getElementById("FBScript")
FBScript = document.createElement("script")
FBScript.id = "FBScript"
FBScript.async = true
FBScript.src = "//connect.facebook.net/en_US/all.js"
PageScript.parentNode.insertBefore(FBScript, PageScript)

页面重新加载可能是由于代码中的以下行：

FB.Event.subscribe('auth.login', (response) ->
    window.location = window.location
)

auth.login状态从auth更改为unknown时会触发{p> connected，因此当您连接时，代码会执行，并且当您重新加载页面时功能，页面重新加载。删除行:: window.location = window.location应该解决它。

FB.api调用后重新加载不需要的页面
