我正在通过Facebook sdk获取信息,但到目前为止,我只得到用户的身份和名称,尽管我确信有一个电子邮件可用,因为它是我的帐户.我一直在看几个答案,但是迄今为止还没有人解决我的问题.
我做错了什么,为什么我要求几个权限不会返回更多的数据？
我做错了什么,为什么我要求几个权限不会返回更多的数据？
这是我的代码：
fbLoginManager.logInWithReadPermissions(["public_profile","email","user_friends","user_about_me","user_birthday"],handler: { (result,error) -> Void in
if ((error) != nil)
{
// Process error
println("There were an error: \(error)")
}
else if result.isCancelled {
// Handle cancellations
fbLoginManager.logout()
}
else {
var fbloginresult : FBSDKLoginManagerLoginResult = result
if(fbloginresult.grantedPermissions.contains("email"))
{
println(fbloginresult)
self.returnUserData()
}
}
})
func returnUserData()
{
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graPHPath: "me",parameters: nil)
graphRequest.startWithCompletionHandler({ (connection,result,error) -> Void in
if ((error) != nil)
{
// Process error
println("Error: \(error)")
}
else
{
println("fetched user: \(result)")
if let userName : NSString = result.valueForKey("name") as? NSString {
println("User Name is: \(userName)")
}
if let userEmail : NSString = result.valueForKey("email") as? NSString {
println("User Email is: \(userEmail)")
}
}
})
}
哪个返回：
fetched user: {
id = 55555555;
name = "Kali Aney";
}
User Name is: Kali Aney
由于Graph-API版本2.4(Pod版本4.4.0),Facebook Graph API破坏了它的向后兼容性(以默认方式使用).
FB Graph-API 2.4不返回用户的所有默认字段
要解决这个问题,您可以使用明确的图形版本2.3：
[FBSDKGraphRequest alloc] initWithGraPHPath：@“me”参数：nil tokenString：[FBSDKAccessToken currentAccessToken] .tokenString版本：@“v2.3”HTTPMethod：nil]
在这种情况下,FB保证v2.3将至少在现在2年后提供.
https://developers.facebook.com/docs/graph-api/overview：
The Graph API has multiple versions available to access at any one
time. Each version contains a set ofcore fields and edge operations.
We make a guarantee that those core APIs will be available and
un-modified in that version for at least 2 years from release. The
platform changelog can tell you which versions are currently
available.
要么
您可以通过询问您感兴趣的特定字段来使用新的Graph-API(v2.4)：
[[FBSDKGraphRequest alloc] initWithGraPHPath：@“me”参数：@ {@“fields”：@“email,name”}]
