当我通过我的应用程序登录Facebook时,一切正常,但我在发布到墙上时遇到了问题。
- (NSString *) postToFBWallStatus:(NSString *) status andSetDelegate: (id) delegate
{
if (! isFBLoggedIn)
{
return @"NotLoggedin";
}
NSString *message = status;
NSLog(@"Appdelegate: postToFBWallStatus:andSetDelegate:");
NSLog(@"to be delegate class: %@",[delegate class]);
NSURL *url = [NSURL URLWithString:@"https://graph.facebook.com/me/feed"];
ASIFormDataRequest *newRequest = [ASIFormDataRequest requestWithURL:url];
[newRequest setPostValue:message forKey:@"message"];
[newRequest setPostValue:@"" forKey:@"name"];
[newRequest setPostValue:@"" forKey:@"caption"];
[newRequest setPostValue:@"" forKey:@"description"];
[newRequest setPostValue:@"" forKey:@"link"];
[newRequest setPostValue:@"" forKey:@"picture"];
[newRequest setPostValue:_accessToken forKey:@"access_token"];
[newRequest setDidFinishSelector:@selector(postToWallFinished:)];
[newRequest setDidFailSelector:@selector(postToWallFailed:)];
[newRequest setDelegate:delegate];
[newRequest startAsynchronous];
return @"Loggedin";
}
当我发布到Facebook墙上时,我收到此消息:
error = {
message = "Invalid access token signature.";
type = OAuthException;
};
答案 0 :(得分:0)
您必须使用用户的access_token
将信息发布到他们的墙上。此外,用户需要允许API调用的publish_stream
权限才能工作。对用户进行身份验证时,请将publish_stream
添加到权限范围。
