Facebook iOS上传视频“无法从访问令牌检索会话密钥”。

问题描述

限时删除！！

我想使用ios-sdk在Facebook上上传视频

I want to upload video on facebook using ios-sdk

我查看讨论中的讨论并尝试在我的应用程序中实现

I check discussion in question iPhone Facebook Video Upload and try to implement it in my application

我尝试您的代码但不成功

I try to your code but not succeed

1. 我下载了您的代码


2. 从您的src中取出FBVideoUpload.h / m类别，将其加入我的专案


3. #includeFBVideoUpload.hin FBConnect.h


4. 然后我为上传视频编码如下

1. I download your code https://github.com/zoul/facebook-ios-sdk
2. take the FBVideoUpload.h/m classes from your src add add into my project
3. #include "FBVideoUpload.h" in FBConnect.h
4. then I code for upload video as follow

$ b b

这是代码

This is Code

FBVideoUpload *upload = [[FBVideoUpload alloc] init];
upload.accessToken = facebookObj.accessToken;
upload.apiKey = fbAppKey;
upload.appSecret = fbAppSecret;
NSString *filePath = @"/Users/pratgupta/Library/Application Support/iPhone Simulator/4.1/Media/DCIM/100APPLE/IMG_0010.M4V";
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
NSData *data = [NSData dataWithContentsOfFile:filePath];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                               data, @"",
                                               @"test", @"title",
                                               @"upload testing", @"description",
                                               @"EVERYONE", @"privacy",
                                               nil];
[upload startUploadWithURL:fileURL params:params delegate:self];

但在日志中遇到错误，

无法从访问令牌。

But got the error in Logs i.e
Unable to retrieve session key from the access token.

这是由于

if ([self sessionID] == nil) {
        NSLog(@"Unable to retrieve session key from the access token);
        return;
}

在类FBVideoUpload中

in class FBVideoUpload

对于登录我正在使用此代码

For Login I am using this code

fbPermissions =  [[NSArray arrayWithObjects:
                       @"read_stream", @"offline_access", @"publish_stream",nil] retain];
facebookObj = [[Facebook alloc] initWithAppId:fbAppId];
[facebookObj authorize:fbPermissions delegate:self];

我可以从Facebook获取我的更新，然后会话在这里确定。

你能告诉我我在做什么？

I am able to fetch my updates from facebook so then session is ok here.
Can you please tell me What wrong I am doing?

EDIT

更改zoul建议的登录步骤后，我现在没有收到sessionID错误日志..我的请求现在发送到fb服务器但获取此响应

EDIT
After changing the login steps suggested by the zoul I am now not getting the sessionID error log.. My request is now sending to the fb server but getting this response

推荐答案

请参阅：

您的问题看起来像是使用现代的应用程式切换验证机制。这导致不同的访问令牌，因此视频上传黑客不工作。切换到旧的身份验证方案很容易，请参见此分支中的（向 Facebook 类添加 forceOldStyleAuth 属性）。

Your problem looks like you are using the modern, app-switching authentication scheme. That results in a different access token and therefore the video uploading hack does not work. Switching to the older authentication scheme is easy, see code in this branch (it adds a forceOldStyleAuth property to the Facebook class).

对于上传的字典，我的代码看起来如下：

As for the dictionary to pass with the upload, here’s how my code looks:

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
    @"Sample video title", @"title",
    @"Sample video description", @"description",
    nil];
upload = [[FBVideoUpload alloc] init];
[upload setApiKey:kAPIKey];
[upload setAccessToken:facebook.accessToken];
[upload setAppSecret:kAppSecret];
[upload startUploadWithURL:movieURL params:params delegate:self];

这适用于我。
