ios - 如何使用 SLRequest 获取大尺寸的 facebook 个人资料图片？

Question

我已经使用了SLRequest获取个人资料信息，并且我遵循了在 iOS6 中获取用户个人资料图片？获取个人资料图像。但它返回50x50图像尺寸。我需要大尺寸的个人资料图片。谁能给我一些想法来做到这一点SLRequest？

Answer 1

使用以下 URL 获取大图：

https://graph.facebook.com/fb_user_id/picture?type=large

对于封面图片，请使用以下内容：

http://graph.facebook.com/fb_user_id?fields=cover

这将返回：

{
  "cover": {
    "id": "XXX", 
    "source": "cover_image_url", 
    "offset_y": 66
  }, 
  "id": "XXXXXX"
}

Answer 2

您可以获得个人资料图片的大图为

[NSURL URLWithString:@"https://graph.facebook.com/me/picture?type=large"];

类型参数支持

enum{square,small,normal,large}

Answer 3

这是swift 3的答案。

1. 您必须在他或她的设备中访问用户的 facebook 帐户，这使用 accountStore API：

     func accessFacebookAccount(onCompletion: @escaping(_ tokenCredential: 
     String, 
      _ facebookAccount: ACAccount) -> Void, onError: @escaping (_ 
    errorMessage:  String?) -> Void) {
   
   
           let accountStore = ACAccountStore()
           let facebookAccountType = accountStore.accountType(withAccountTypeIdentifier: ACAccountTypeIdentifierFacebook)
   
           let options = [
           "ACFacebookAppIdKey" : "529210493918001",
           "ACFacebookPermissionsKey" : ["email","public_profile"],
           "ACFacebookAudienceKey" : ACFacebookAudienceOnlyMe] as [String : Any]
   
       accountStore.requestAccessToAccounts(with: facebookAccountType, options: options) { (granted, error) in
           if granted {
   
   
               let fbAccount = accountStore.accounts(with: facebookAccountType).last as? ACAccount
   
               let credential = fbAccount?.credential
   
   
               let token = credential?.oauthToken
               onCompletion(token!, fbAccount!)
   
           } else {
               let error = "Access to Facebook was not granted."
               onError(error)
   
           }
       }
   }
   

2. 收到响应后，用户就授予了对该帐户的访问权限。您可以使用 ACAccount 对象并通过 SLRequest 访问 facebook 信息：

   func getFacebookInfoViaAccounts (_ fbAccount: ACAccount) {
   
   
   let myURL = URL(string: "https://graph.facebook.com/me")
   
   let request = SLRequest.init(forServiceType: SLServiceTypeFacebook, requestMethod: .GET, url: myURL, parameters: ["fields":"email, first_name, last_name,birthday, gender"])
   
   request?.account = fbAccount
   
   request?.perform(handler: { (dataResponse, urlResponse, error) in
   
       if error == nil {
   
           let json = try? JSONSerialization.jsonObject(with: dataResponse!, options: [ JSONSerialization.ReadingOptions.allowFragments])
   
           if let dict = json as? [String: Any] {
   
               print("My data \(dict)")
           }
       }
   
   })
   
   let myPhotoURl = URL(string: "https://graph.facebook.com/me/picture")
   
   let requestPhoto = SLRequest.init(forServiceType: SLServiceTypeFacebook, requestMethod: .GET, url: myPhotoURl, parameters: ["type":"large"])
   
   requestPhoto?.account = fbAccount
   
   requestPhoto?.perform(handler: { (dataResponse, urlResponse, error) in
   
       if error == nil {
   
           print("URL DE LA PHOTO \(urlResponse?.value(forKey: "URL"))")
       }
   
   })
   
   }
   

以上是获取用户个人资料图像和信息（如电子邮件、性别和生日）的代码。

这是 tinder 等应用程序获取您的数据的方式，如果用户的 facebook 帐户与他或她的 iphone 相关联，则不会要求用户登录 facebook 帐户。

我希望这对某人有所帮助，编码愉快:)。
