Question

我需要发布到用户的Facebook Feed。

基于其他几个SO问题，我提出了以下发布请求：

let request = GraphRequest(graphPath: "me/feed", parameters: ["message" : "Hello world"], accessToken: accessToken, httpMethod: .POST, apiVersion: GraphAPIVersion.defaultVersion)
request.start({ (response, requestResult) in

    switch requestResult {
    case .failed(let error):
        print("error in graph request:", error)

    case .success(let graphResponse):
        if let responseDictionary = graphResponse.dictionaryValue {
            print(responseDictionary)
        }
    }
})

由于

而失败

error =         {
    code = 200;
    "fbtrace_id" = GMp2cebddNb;
    message = "(#200) Requires either publish_actions permission, or manage_pages and publish_pages as an admin with sufficient administrative permission";
    type = OAuthException;
};

根据消息，问题似乎很容易解决 - 我只需要获得publish_actions或manage_pages和publish_pages权限。基于这个SO question，这看起来很简单，我最终用这个包装代码进行发布：

let loginManager = LoginManager()
loginManager.logIn([PublishPermission.custom("publish_actions")], viewController: self) { (result) in

    print(">> \(AccessToken.current?.grantedPermissions)")

    switch result {

    case .cancelled:
        print(">>>> Cancelled")

    case .failed(let error):
        print(">>>> Error: \(error)" )

    case .success(grantedPermissions: _, declinedPermissions: _, token: let accessToken):
        print(">>>> Logged in!")
        let request = GraphRequest(graphPath: "me/feed", parameters: ["message" : post], accessToken: accessToken, httpMethod: .POST, apiVersion: GraphAPIVersion.defaultVersion)
        request.start({ (response, requestResult) in

            switch requestResult {
            case .failed(let error):
                print("error in graph request:", error)
                break
            case .success(let graphResponse):
                if let responseDictionary = graphResponse.dictionaryValue {
                    print(responseDictionary)
                }
            }
        })
    }
}

现在＆＃34;搞笑＆＃34;部分是，然后Facebook SDK显示一个页面告诉我，我以前使用Facebook登录到我的应用程序，并询问我是否要继续。当我按下继续时，SafariViewController解散并执行.cancelled分支。这里发生了什么？我没有被取消，也没有被要求授予我在Feed上发布任何内容的权限。

PS：我尝试先退出（loginManager.logOut()和/或AccessToken.current = nil），在这种情况下，.success分支会执行，但会再次出现相同的错误"(#200) Requires either publish_actions permission, or manage_pages and publish_pages as an admin with sufficient administrative permission"。< / p>

在这种情况下，AccessToken.current.grantedPermissions包含：

Set([FacebookCore.Permission(name: "user_friends"),
    FacebookCore.Permission(name: "publish_pages"), 
    FacebookCore.Permission(name: "user_location"), 
    FacebookCore.Permission(name: "email"), 
    FacebookCore.Permission(name: "user_likes"), 
    FacebookCore.Permission(name: "pages_show_list"), 
    FacebookCore.Permission(name: "manage_pages"), 
    FacebookCore.Permission(name: "user_photos"), 
    FacebookCore.Permission(name: "public_profile"), 
    FacebookCore.Permission(name: "user_posts"), 
    FacebookCore.Permission(name: "user_birthday")])

所以没有publish_actions许可！为什么登录成功通过而不授予我我要求的权限？此外，我显然有"manage_pages"和"publish_pages"，为什么这还不够？

已删除publish_actions权限。

由于他们没有提及任何替代方案，因此无法再发布到用户Feed。
