我正在使用图表api从Facebook登录名返回我的姓名和电子邮件。这是我使用的代码 - 名称返回正常,但电子邮件是零:

func getUserInfo() {
    let params = ["fields" : "email, name"]
    let graphRequest = GraphRequest(graphPath: "me", parameters: params)
    graphRequest.start {
        (urlResponse, requestResult) in

        switch requestResult {
        case .failed(let error):
            print("error in graph request:", error)
            break
        case .success(let graphResponse):
            if let responseDictionary = graphResponse.dictionaryValue {
                print(responseDictionary)

                if let name = responseDictionary["name"] {
                    self.nameLabel.text = "Logged in as: \n\(name)"
                }

                if let email = responseDictionary["email"] {
                    self.emailLabel.text = "Your email is: \n\(email)"
                } else {
                    self.emailLabel.text = "Your email is: "
                }
                print(responseDictionary["name"])
                print(responseDictionary["email"])
            }
        }
    }
}

这是打印到我的控制台的内容:

["id": 1653899307960705, "name": *my name removed for privacy*]
Optional(*my name removed for privacy*)
nil

我不确定我的代码是错误还是只是一个错误 - 我将电子邮件和名称都指定为我的参数,但正如您所看到的,只有名称会回来。任何人都知道为什么会这样吗?

您的代码绝对正确,Facebook图形API无法提供电子邮件的可能性很小:

  1. 已注册用户已提交其电子邮件但未经过验证
  2. 用户已将电子邮件(可见性)设置为仅限朋友(非公开)的私人/有限访问权
  3. 检查/您的帐户的帐户设置(电子邮件有效且已经过验证,并且是公开的)

我忘了接受电子邮件许可,所以我在这里分享您的代码以获得许可。

func fbLoginInitiate()
    {
        let loginManager = FBSDKLoginManager()
        loginManager.logInWithReadPermissions(["public_profile", "email","user_friends"], handler: {(result:FBSDKLoginManagerLoginResult!, error:NSError!) -> Void in
            if (error != nil) {
                // Process error
                self.removeFbData()
            } else if result.isCancelled {
                // User Cancellation
                self.removeFbData()
            } else {
                //Success                
                if result.grantedPermissions.contains("email") && result.grantedPermissions.contains("public_profile") && result.grantedPermissions.contains("user_friends"){
                    //Here you need to call your function for graphRequest 
                    self.getUserInfo()
                } else {
                    //Handle error
                }
            }
        })
    }
func removeFbData()
    {
        //Remove FB Data
        let fbManager = FBSDKLoginManager()
        fbManager.logOut()
        FBSDKAccessToken.setCurrentAccessToken(nil)
    }
