How to process the response data of FBSDKGraphRequest in Swift 3
提问by KD.
I have integrated the FB latest SDK(non-swift) and log in is working fine. All I need to know how do I parse the Graph response data since its not a valid JSON
我已经集成了 FB 最新的 SDK（非 swift）并且登录工作正常。我只需要知道如何解析 Graph 响应数据，因为它不是有效的 JSON
Working code:
工作代码：
func configureFacebook()
{
login.readPermissions = ["public_profile", "email", "user_friends"];
login.delegate = self
}
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
print("Login buttoon clicked")
let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"first_name,email, picture.type(large)"])
graphRequest.start(completionHandler: { (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print(result)
}
})
}
With output:
有输出：
Login button clicked
Optional({
"first_name" = KD;
id = 10154CXXX;
picture = {
data = {
"is_silhouette" = 0;
url = "https://scontent.xx.fbcdn.net/v/t1.0-1/p200x200/XXXn.jpg?oh=a75a5c1b868fa63XXX146A";
};
};
})
So what format should I convert the above data to get values like URL or first_name etc?
那么我应该将上述数据转换为什么格式来获取 URL 或 first_name 等值？
Also I tried converting to NSDictionaryand got error:
我也尝试转换为NSDictionary并得到错误：
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
print("Login buttoon clicked")
let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"first_name,email, picture.type(large)"])
graphRequest.start(completionHandler: { (connection, result, error) -> Void in
if ((error) != nil)
{
print("Error: \(error)")
}
else
{
do {
let fbResult = try JSONSerialization.jsonObject(with: result as! Data, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
print(fbResult.value(forKey: "name"))
} catch {
print(error)
}
}
})
}

You can simply do it as follows:
您可以简单地执行以下操作：
let data:[String:AnyObject] = result as! [String : AnyObject]
print(data["first_name"]!)
Swift 3:
斯威夫特 3：
Safe unwrapping & Anyinstead of AnyObject
安全解包 &Any而不是AnyObject
if let data = result as? [String:Any] {
}

Swift 5Code for question and issue and solution:
问题和问题以及解决方案的Swift 5代码：
Implementation:
执行：
let graphRequest:GraphRequest = GraphRequest(graphPath: "me", parameters: ["fields":"first_name,email,picture.type(large)"])
graphRequest.start(completionHandler: { (connection, result, error) -> Void in
if ((error) != nil) {
print("Error: \(String(describing: error))")
}
else {
guard let rDic = result as? NSDictionary else {
SVProgressHUD.showError(withStatus: "facebook Did not allowed loading email, please set that while updating profile.")
return
}
print("rDic = ", rDic)
}
})
Output:
输出：
rDic = {
email = "[email protected]";
"first_name" = Mr. Me;
id = #################;
picture = {
data = {
height = 32;
"is_silhouette" = 0;
url = "https://platform-lookaside.fbsbx.com/platform/profilepic/?asid=################&height=200&width=200&ext=################&hash=################";
width = 32;
};
};
}
P.S.: Thanks to KD and Bista their question and answer helped me figure this.
