我试图在这个问题上挣扎两天.我正在使用Fabric SDK和Rest工具包,试图为Twitter使用不同的Rest API Web服务.我可以使用具有authTokenSecret,authToken和其他值的会话对象的TWTRLogInButton成功登录.当我尝试获取用户时间线时,我总是得到失败的响应,作为：
{“errors”：[{“code”：215,“message”：“Bad Authentication data.”}]}
完整错误日志是：

请帮我调试这个问题.谢谢.
解决方法
在使用Fabric SDK进行实验后,我成功地进行了集成.我得出了一些结论,并希望与你们分享.
1)当您第一次成功登录Twitter时,已为用户创建了一个TWTRSession会话.即使您关闭应用程序并重新打开它,它也会持续.
2)如果已经为您创建了会话,并且您尝试登录获取另一个会话对象而不注销,则将返回身份验证错误.
3)您可以使用以下方法检查会话是否存在：
if([[Twitter sharedInstance] session])
{
NSLog(@"session already present!!!");
NSLog(@"signed in as %@",[[[Twitter sharedInstance] session] userName]);
}
else
{
NSLog(@"you need to login!!");
}
4)我会建议使用登录
[[Twitter sharedInstance] logInWithCompletion：^(TWTRSession * session,NSError * error)];
代替：
[TWTRLogInButton buttonWithLogInCompletion：^(TWTRSession * session,NSError * error)];
Use Twitter’s login button only,when you are sure that no session
exists currently.
5)如果Twitter的身份验证真的取笑你,请卸载该应用程序并尝试全新安装.这是最后的解决方案！
6)要从会话注销,请使用[[Twitter sharedInstance] logout];
编码部分：
我假设您已经按照Fabric mac app执行了所有步骤.
首先登录用户,然后发出时间表请求.
-(void) loginUserToTwitter
{
if([[Twitter sharedInstance] session])
{
NSLog(@"session already present!!!");
NSLog(@"signed in as %@",[[[Twitter sharedInstance] session] userName]);
[self getUserTimeline];
}
else
{
NSLog(@"session not found. Make new request!");
[[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session,NSError *error) {
if(error)
NSLog(@"error occurred... %@",error.localizedDescription);
else
{
NSLog(@"Successfully logged in with session :%@",session);
[self getUserTimeline];
}
}];
}
}
-(void) getUserTimeline
{
NSURLRequest *request = [[[Twitter sharedInstance] apiclient] URLRequestWithMethod:@"GET" URL:@"https://api.twitter.com/1.1/statuses/user_timeline.json"
parameters:@{@"userid": [Twitter sharedInstance].session.userID,@"count" : @"5",@"screen_name" : [Twitter sharedInstance].session.userName} error:nil];
NSURLResponse *response;
NSError *error;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if(!data)
{
NSLog(@"error....: %@",error.localizedDescription);
}
else
{
Nsstring *string = [[Nsstring alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"%@",string);
[twitterResponse removeAllObjects];
NSArray *arrayRep = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
twitterResponse = [NSMutableArray arrayWithArray:[TWTRTweet tweetsWithJSONArray:arrayRep]];
[_tableView reloadData];
}
}
我更喜欢使用Twitter SDK的方法来使用[TWTRTweet tweetsWithJSONArray：arrayRep]而不是Restkit来提取推文.这里的事情真的很容易处理.
在Twitter的标准风格中显示推文：
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view,typically from a nib.
// Setup tableview
self.tableView.estimatedRowHeight = 150;
self.tableView.rowHeight = UITableViewAutomaticDimension; // Explicitly set on iOS 8 if using automatic row height calculation
self.tableView.allowsSelection = NO;
[self.tableView registerClass:[TWTRTweetTableViewCell class] forCellReuseIdentifier:@"TweetCell"];
}
#pragma mark - Tableview Methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return twitterResponse.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static Nsstring *cellID = @"TweetCell";
TWTRTweetTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID forIndexPath:indexPath];
TWTRTweet *tweet = twitterResponse[indexPath.row];
[cell configureWithTweet:tweet];
return cell;
}
// Calculate the height of each row. Must to implement
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
TWTRTweet *tweet = twitterResponse[indexPath.row];
return [TWTRTweetTableViewCell heightForTweet:tweet width:CGRectGetWidth(self.view.bounds)];
}
注意：
从here下载Fabric SDK.您必须输入电子邮件地址.他们会通过电子邮件向您发送一些下载链接,您必须按照一些步骤操作. Fabric Mac App将让您完全配置xcode项目.
希望能帮助到你！
