iphone – 如何使用twitter api v1.1(Twitter错误215)获取用户详细信息

概述我使用twitter提供的twitter api来获取详细信息 不能执行它,甚至试图通过认证数据 像消费者密钥,消费者密钥,令牌,但结果是一样的. 我能够登录和接收twitter身份验证令牌,但无法获取用户详细信息. 以下代码由我使用(我正在使用MGtwitter引擎)： NSMutableURLRequest *request =[[NSMutableURLRequest alloc]initW 我使用twitter提供的twitter API来获取详细信息

以下代码由我使用(我正在使用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];

错误如下所示：

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

解决方法 首先,您需要验证您的请求(获取权限).

第二,请参阅以下步骤：

下载FHSTwitterEngine Twitter图书馆.

2.将文件夹“FHSTwitterEngine”添加到您的项目中,然后添加#import“FHSTwitterEngine.h”.

3.将SystemConfiguration.framework添加到您的项目中.

Usage : 1.in the [VIEwDIDLoad] add the following code.

UIbutton *logIn = [UIbutton buttonWithType:UIbuttonTypeRoundedRect];    logIn.frame = CGRectMake(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];

并且不要忘记导入代理FHSTwitterEngineAccesstokenDelegate.

you need to get the permission for your request,with the following method which will present Login window:

- (voID)showLoginWindow:(ID)sender {    [[FHSTwitterEngine sharedEngine]showOAuthLoginControllerFromVIEwController:self withCompletion:^(BOol success) {        NSLog(success?@"L0L success":@"O noes!!! Loggen faylur!!!");    }];}

当登录窗口出现时,输入您的Twitter用户名和密码来验证您的请求.

add the following methods to your code:

-(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.Now you are ready to get your request,with the following method(in this method I created a Twitter search for some Hashtag,to get the screen_name for example):

- (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;                }            });        }    });}

就这样.
我从搜索查询中获取了screen_name,您可以使用以下方法获取用户的时间轴：

// 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：请参阅FHSTwitterEngine.h以了解需要使用的方法.
注意：获取< consumer_key>和< consumer_secret>您需要访问这个link 在Twitter上注册您的应用程序.
