ios - 我的应用程序正在请求 “Have offline access” 的权限，为什么？

Question

我的应用程序正在请求“离线访问”权限，为什么？这是最奇怪的事情。我做了一些搜索，但还没有真正找到任何有效的东西。我尝试过将这些用于范围:

https://www.googleapis.com/auth/plus.profile.emails.read 
https://www.googleapis.com/auth/plus.login

这似乎没有帮助。

下面是屏幕截图和我的一些代码，可帮助您了解发生了什么:

我的一些代码:

    #import "ViewController.h"

NSString *callbakc =  @"http://localhost/";
NSString *client_id = @“CLIENT ID“;
NSString *scope = @"https://www.googleapis.com/auth/userinfo.email+https://www.googleapis.com/auth/userinfo.profile+https://www.google.com/reader/api/0/subscription";
NSString *secret = @“SECRET”;
NSString *visibleactions = @"http://schemas.google.com/AddActivity";

@interface ViewController () {
NSString *authAccessToken;
UIAlertController *alertController;
}

@property (strong, nonatomic) NSMutableData *receivedData;
@property (weak, nonatomic) IBOutlet UIWebView *webView;

@end

这是来自https://stackoverflow.com/questions/32210920/why-is-my-app-asking-for-permission-to-have-offline-access?answertab=oldest#tab-top :

This is normal behavior and occurs when the user has granted permission already.

Basically, no need to worry about it unless you really don't want that showing up, in that case, you need to un auth the users old token before requesting a new one.

我不太确定如何操作，因为我以前没有这样做过，但在授权新 token 之前，您需要取消对旧 token 的授权。

您需要修改 -(void)getUserInfo:(NSString *)token 方法。
