如何使用twitter api v1.1獲取用戶詳細信息（Twitter錯誤215）

Question

我使用了twitter提供的twitter api來獲取詳細信息但無法執行它，甚至嘗試傳遞身份驗證數據，如消費者密鑰，消費者密鑰，令牌，但結果相同。
我能夠登錄和接收Twitter身份驗證令牌，但無法獲取用戶詳細信息。 下面的代碼由我使用（我使用的是MGtwitter引擎）：

NSMutableURLRequest *request =[[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://api.twitter.com/1.1/users/show.json?screen_name=%@",username]]];

NSData *returnData = [ NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil ];

NSString *returnString = [[NSString alloc]initWithData:returnData encoding:NSUTF8StringEncoding];
    NSError *err = nil;

twitterLogin = [NSJSONSerialization JSONObjectWithData:[returnString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&err];

錯誤如下所示：

errors = (
{
    code = 215;
    message = "Bad Authentication data";
} );

Answer 1

首先，您需要Authenticate您的請求（獲取權限）。

第二，請參閱以下步驟 ：

1.下載FHSTwitterEngine Twitter庫。

2.將文件夾FHSTwitterEngine “添加到您的項目和#import "FHSTwitterEngine.h" 。

3.add SystemConfiguration.framework到您的項目。

用法：1。在[ViewDidLoad]添加以下代碼。

UIButton *logIn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    logIn.frame = CGRectMake(100, 100, 100, 100);
    [logIn setTitle:@"Login" forState:UIControlStateNormal];
    [logIn addTarget:self action:@selector(showLoginWindow:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:logIn];

[[FHSTwitterEngine sharedEngine]permanentlySetConsumerKey:@"<consumer_key>" andSecret:@"<consumer_secret>"];
    [[FHSTwitterEngine sharedEngine]setDelegate:self];

並且不要忘記導入委托FHSTwitterEngineAccessTokenDelegate 。

2. 您需要獲得您的請求的權限，使用以下方法將顯示登錄窗口：

- (void)showLoginWindow:(id)sender {
    [[FHSTwitterEngine sharedEngine]showOAuthLoginControllerFromViewController:self withCompletion:^(BOOL success) {
        NSLog(success?@"L0L success":@"O noes!!! Loggen faylur!!!");
    }];
}

顯示“登錄”窗口時，輸入您的Twitter Username和Password以authenticate您的請求。

3. 將以下方法添加到您的代碼中：

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [[FHSTwitterEngine sharedEngine]loadAccessToken];
    NSString *username = [[FHSTwitterEngine sharedEngine]loggedInUsername];// self.engine.loggedInUsername;
    if (username.length > 0) {
        lbl.text = [NSString stringWithFormat:@"Logged in as %@",username];
        [self listResults];


    } else {
        lbl.text = @"You are not logged in.";
    }

}
- (void)storeAccessToken:(NSString *)accessToken {
    [[NSUserDefaults standardUserDefaults]setObject:accessToken forKey:@"SavedAccessHTTPBody"];
}

- (NSString *)loadAccessToken {
    return [[NSUserDefaults standardUserDefaults]objectForKey:@"SavedAccessHTTPBody"];
}

4.現在您已准備好通過以下方法獲取您的請求（在此方法中，我創建了一個Twitter搜索某些Hashtag ，例如獲取screen_name ）：

- (void)listResults {

    dispatch_async(GCDBackgroundThread, ^{
        @autoreleasepool {
            [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

        // the following line contains a FHSTwitterEngine method wich do the search.

            dict = [[FHSTwitterEngine sharedEngine]searchTweetsWithQuery:@"#iOS" count:100 resultType:FHSTwitterEngineResultTypeRecent unil:nil sinceID:nil maxID:nil];
          // NSLog(@"%@",dict);
            NSArray *results = [dict objectForKey:@"statuses"];

          //  NSLog(@"array text = %@",results);
            for (NSDictionary *item in results) {
                NSLog(@"text == %@",[item objectForKey:@"text"]);
                NSLog(@"name == %@",[[item objectForKey:@"user"]objectForKey:@"name"]);
                NSLog(@"screen name == %@",[[item objectForKey:@"user"]objectForKey:@"screen_name"]);
                NSLog(@"pic == %@",[[item objectForKey:@"user"]objectForKey:@"profile_image_url_https"]);
            }

            dispatch_sync(GCDMainThread, ^{
                @autoreleasepool {
                    UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Complete!" message:@"Your list of followers has been fetched" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                    [av show];
                    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
                }
            });
        }
    });
}

就這樣。 我剛剛從搜索查詢中獲取了screen_name，您可以使用以下方法為用戶獲取時間軸：

// statuses/user_timeline
- (id)getTimelineForUser:(NSString *)user isID:(BOOL)isID count:(int)count;
- (id)getTimelineForUser:(NSString *)user isID:(BOOL)isID count:(int)count sinceID:(NSString *)sinceID maxID:(NSString *)maxID; 

而不是上面的搜索方法。

注意：請參閱FHSTwitterEngine.h以了解您需要使用的方法。 注意：要獲取<consumer_key>和<consumer_secret>您需要訪問此鏈接以在Twitter中注冊您的應用程序。

Answer 2

獲得MKAlatrash還原后的解決方案，以獲取用戶配置文件遵循代碼中的某些步驟，如下所示：

[[FHSTwitterEngine sharedEngine]getProfileImageForUsername:username andSize:FHSTwitterEngineImageSizeNormal];

跳轉到此函數的定義並替換if ... else if部分

if ([userShowReturn isKindOfClass:[NSError class]]) {
        return [NSError errorWithDomain:[(NSError *)userShowReturn domain] code:[(NSError *)userShowReturn code] userInfo:[NSDictionary dictionaryWithObject:request forKey:@"request"]];
        NSLog(@"user show return %@",userShowReturn);
    } else if ([userShowReturn isKindOfClass:[NSDictionary class]]) {
        return userShowReturn;
        NSString *url = [userShowReturn objectForKey:@"profile_image_url"]; // normal

        if (size == 0) { // mini
            url = [url stringByReplacingOccurrencesOfString:@"_normal" withString:@"_mini"];
        } else if (size == 2) { // bigger
            url = [url stringByReplacingOccurrencesOfString:@"_normal" withString:@"_bigger"];
        } else if (size == 3) { // original
            url = [url stringByReplacingOccurrencesOfString:@"_normal" withString:@""];
        }

        id ret = [self sendRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]]];

        if ([ret isKindOfClass:[NSData class]]) {
            return [UIImage imageWithData:(NSData *)ret];
        }

        return ret;
    }

這真的很有用，謝謝
