Facebook Graph API GET request - Should contain "fields" parameter (Swift, Facebook SDK v4.5.1)
提问by Armin
My iOS app uses Facebook's Graph API Request during sign up to get user information, which worked fine prior to upgrading to Facebook's newest SDK. After upgrading, I'm getting a runtime error stating: "FBSDKLog: starting with Graph API v2.4, GET requests for /me should contain an explicit "fields" parameter".
我的 iOS 应用程序在注册期间使用 Facebook 的 Graph API 请求来获取用户信息，在升级到 Facebook 的最新 SDK 之前运行良好。升级后，我收到一个运行时错误，指出：“FBSDKLog：从 Graph API v2.4 开始，/me 的 GET 请求应包含显式的“字段”参数”。
Here is the code:
这是代码：
func requestFacebook() {
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
println("Error: \(error)")
}
else if error == nil
{
let birthday : NSString = (result.valueForKey("birthday") as? NSString)!
var currentDate = NSDate()
var birthdayFormatter = NSDateFormatter()
let userCalendar = NSCalendar.currentCalendar()
birthdayFormatter.dateFormat = "MM/DD/YYYY"
var birthdayNSDate = birthdayFormatter.dateFromString(birthday as String)
var userAge = self.calculateAge(birthdayNSDate!)
PFUser.currentUser()!["age"] = userAge
var facebookID: NSString = (result.valueForKey("id") as? NSString)!
var pictureURL = "https://graph.facebook.com/\(facebookID)/picture?type=large&return_ssl_resources=1"
var URLRequest = NSURL(string: pictureURL)
var URLRequestNeeded = NSURLRequest(URL: URLRequest!)
NSURLConnection.sendAsynchronousRequest(URLRequestNeeded, queue: NSOperationQueue.mainQueue(), completionHandler: {(response: NSURLResponse!,data: NSData!, error: NSError!) -> Void in
if error == nil {
var picture = PFFile(data: data)
PFUser.currentUser()!["picture"] = picture
PFUser.currentUser()!.saveInBackgroundWithBlock({ (success, error) -> Void in
if error == nil {
var userPicture:PFFile = PFUser.currentUser()!.valueForKey("picture") as! PFFile
userPicture.getDataInBackgroundWithBlock { (imageData, error) -> Void in
if error == nil {
self.meProfileImageView.image = UIImage(data: imageData!)
var userName:String = PFUser.currentUser()!.valueForKey("username") as! String
var userAge:Int = PFUser.currentUser()!.valueForKey("age") as! Int
self.meLabel.text = "\(userName), \(userAge)"
self.findFriends()
}
}
} else {
println(error)
}
})
}
else {
println("Error: \(error.localizedDescription)")
}
})
}
})
}
The error message is at the line:
错误消息位于以下行：
let birthday : NSString = (result.valueForKey("birthday") as? NSString)!
This code ran perfectly fine before upgrading to Facebook's SDK v4.5.1, but I don't know what to change to make this work now. Huge thanks to anyone that can help me!
这段代码在升级到 Facebook 的 SDK v4.5.1 之前运行得非常好，但我不知道现在要更改什么才能使其正常工作。非常感谢任何可以帮助我的人！

this line needs a parameters value that is NOT nil
这一行需要一个非零的参数值
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
I'll expand more, for example, and this is psuedo code of sorts:
例如，我将扩展更多，这是各种伪代码：
so for ObjC it would be this, for example, so the the above would read the following:
例如，对于 ObjC 来说就是这样，所以上面的内容如下：
parameters:@{@"fields": @"id, name"}
In swift it would be something similar
很快，它会是类似的东西
something like this:
像这样：
parameters:["fields": "email"]
This is for just two fields, and again it's psuedo code, but you need to specify the parameters
这只是两个字段，也是伪代码，但需要指定参数
UPDATE:
更新：
Im adding this update to show folks where you find the parameters for the fields as described above, here's a quick link:
我添加此更新以向人们展示您可以在何处找到上述字段的参数，这是一个快速链接：
Here's the Paramters field info (this should stay roughly static with FBSDK, some of this is "core" which means it won't really change that much, but I'll update whenever I can):
这是参数字段信息（这应该与 FBSDK 保持大致静态，其中一些是“核心”，这意味着它不会真正改变那么多，但我会尽可能更新）：

use "fields" as Key and then comma separate your values
使用“字段”作为键，然后用逗号分隔您的值
let params = ["fields": "email, friends"]

In Obj-C insert in the logInWithReadPermissions method:
在 Obj-C 中插入 logInWithReadPermissions 方法：
parameters:@{@"fields": @"id, name, email"}
if you leave nil in parameters you only receive id and name in the result object, although you have set for example:
如果您在参数中保留 nil，您只会在结果对象中收到 id 和 name，尽管您已经设置了例如：
NSArray *permissionsArray = @[ @"email", @"public_profile"];
It′s not very clear in the documentation, hope it can helps.
文档里写的不是很清楚，希望能帮到你。

I had the same problem, but adding field options would generate a request error when fetching the user photo. I solved this problem by adding a simple parameters:@{@"fields": @""}to the code:
我有同样的问题，但添加字段选项会在获取用户照片时产生请求错误。我通过parameters:@{@"fields": @""}在代码中添加一个简单的来解决这个问题：
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:[NSString stringWithFormat:@"me/picture"]
parameters:@{@"fields": @""}
HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
if (!error) {
// success
} else {
// fail
}}
];

In Swift, you can declare multiple parameters like this:
在 Swift 中，您可以像这样声明多个参数：
let graphRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email, first_name, last_name, gender, picture"])
