Question

我正在开发一个需要Facebook登录和用户详细信息的应用程序。但是，与以前的应用程序中用于fb登录的代码相同，该代码无法正常工作，我需要为每个字段（例如姓名，电子邮件，图片等）分别发出图形请求。

基本上，每当我尝试执行以下操作时：

connection.add(GraphRequest(graphPath: "/me", parameters:["fields":"email, name, picture"])) { httpResponse, result in
                switch result {
                case .success(let response):
                    guard let userInfo = response.dictionaryValue else {
                        return
                    }
                    userDict["email"] = userInfo["email"]! as Any
                    UserDefaults.standard.set(userDict["email"], forKey: userKeys.email)
                case .failed(let error):
                    print("Graph Request Failed: \(error)")
                }
            }

我收到此错误：

Graph Request Failed: Error Domain=com.facebook.sdk.core Code=8 "(null)" UserInfo={com.facebook.sdk:FBSDKGraphRequestErrorCategoryKey=0, com.facebook.sdk:FBSDKGraphRequestErrorHTTPStatusCodeKey=400, com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Syntax error "Expected end of string instead of "%"." at character 5: email%2C%20name%2C%20picture, com.facebook.sdk:FBSDKGraphRequestErrorGraphErrorCode=2500, com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={
body =     {
    error =         {
        code = 2500;
        "fbtrace_id" = "FIc1yiUL+1z";
        message = "Syntax error \"Expected end of string instead of \"%\".\" at character 5: email%2C%20name%2C%20picture";
        type = OAuthException;
    };
};
code = 400;

在执行此操作时出现类似错误：

connection.add(GraphRequest(graphPath: "/me", parameters:["fields":"picture.type(large)"]))

但是，当我将单个字段作为参数输入时，它不会给出错误。

任何帮助将不胜感激：）

Answer 1

尝试最新版本时，我也遇到相同的错误。我建议您降级到以前的版本。对我来说，以下版本运行良好：

pod 'FBSDKCoreKit', '~> 4.38.0' 
pod 'FBSDKLoginKit', '~> 4.38.0'

之后运行

pod deintegrate

pod install

尝试

    let loginManager = FBSDKLoginManager()
    loginManager.logOut()
    loginManager.logIn(withReadPermissions: ["public_profile", "user_photos" ,"user_videos"], from: self) { (result, error) in
        if error != nil {

        } else if (result?.isCancelled)! {
            print("Cancelled")
        } else {               
            let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields" : "email, id, name"])
            graphRequest.start(completionHandler: { (connection, result, error) -> Void in
                if ((error) != nil) {
                    print("Error: \(String(describing: error))")
                } else {
                    var userName:String?
                    var userID:String?
                    var userIEmail:String? = ""
                    if let user : NSString = (result! as AnyObject).value(forKey: "name") as? NSString {
                        userName = "\(user)"
                    }
                    if let id : NSString = (result! as AnyObject).value(forKey: "id") as? NSString {
                        userID = id as String
                        if userID == UserDefaultsHelper.username{
                            self.ClearUserData = false
                        }
                    }
                    if let email : NSString = (result! as AnyObject).value(forKey: "email") as? NSString {
                        userIEmail = email as String
                    }
                }
            })
        }
    }

Facebook ios sdk图请求仅允许一个字段作为参数
