Weibo SSO认证 和初次请求数据

在进行SSO请求之前 我们要先去新浪微博的开放平台http://open.weibo.com/进行创建应用.以便得到appKey 和AppSecret.

点击创建应用 .进行资料填写  在这里

Apple ID 是现在可以随意填写的 但是在正式应用上线后 需要马上更改

Bundle ID  必须要和Xcode上的 Bundle Identifier 上的一样.1) 导入libWeiboSDK设置代理.WeiboSDKDelegate2)注册Appkey 
    [WeiboSDK enableDebugMode:YES];
    [WeiboSDK registerApp:kAppKey];
    3)创建一个Button用来触发sso请求//创建一个Button来点击请求授权
    
    _ssoButton=[UIButton buttonWithType:UIButtonTypeCustom];
   
   // [_ssoButton setTitle:@"hehehehe" forState:UIControlStateNormal];//要颜色啊
    [_ssoButton setImage:[UIImage imageNamed:@"LoginButton@2x.png"] forState:UIControlStateNormal];
    [_ssoButton addTarget:self action:@selector(ssoButtonRequest) forControlEvents:UIControlEventTouchDown];
    
    [_ssoButton setFrame:CGRectMake(100, 350, 130, 80)];
    
    
    [self.view addSubview:_ssoButton];

4)触发 发送授权请求-(void)ssoButtonRequest
{
    WBAuthorizeRequest*request=[WBAuthorizeRequest request];
    request.redirectURI=kRedirectURI;
    request.scope=@"all";
    request.userInfo = @{@"SSO_From": @"SendMessageToWeiboViewController",
                         @"Other_Info_1": [NSNumber numberWithInt:123],
                         @"Other_Info_2": @[@"obj1", @"obj2"],
                         @"Other_Info_3": @{@"key1": @"obj1", @"key2": @"obj2"}};
    [WeiboSDK sendRequest:request];
    
   
    
}5)接受weibo的响应  
- (void)didReceiveWeiboResponse:(WBBaseResponse *)response
{
    
    
    if ([response isKindOfClass:WBSendMessageToWeiboResponse.class])
    {
        NSString *title = @"发送结果";
        NSString *message = [NSString stringWithFormat:@"响应状态: %d\n响应UserInfo数据: %@\n原请求UserInfo数据: %@",
                             response.statusCode, response.userInfo, response.requestUserInfo];
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:nil
                                              cancelButtonTitle:@"确定"
                                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }
    else if ([response isKindOfClass:WBAuthorizeResponse.class])
    {
        NSString *title = @"认证结果";
        NSString *message = [NSString stringWithFormat:@"响应状态: %d\nresponse.userId: %@\nresponse.accessToken: %@\n响应UserInfo数据: %@\n原请求UserInfo数据: %@",
                             response.statusCode, [(WBAuthorizeResponse *)response userID], [(WBAuthorizeResponse *)response accessToken], response.userInfo, response.requestUserInfo];
        
        
        
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:nil
                                              cancelButtonTitle:@"确定"
                                              otherButtonTitles:nil];
        
        self.wbtoken = [(WBAuthorizeResponse *)response accessToken];
        
        NSLog(@"token=%@", self.wbtoken);
        // 保存授权用户的token   如果需要进行API请求 便要保存密钥
        [[NSUserDefaults standardUserDefaults] setObject:self.wbtoken forKey:@"access_token"];
        
        [alert show];
        [alert release];
    }

}

6)创建一个按钮 触发请求接口数据 (这里以请求200条公共微博为例子.默认20条)
   UIButton*requestDataButton=[UIButton buttonWithType:UIButtonTypeCustom];
    
   [requestDataButton setTitle:@"请求数据" forState:UIControlStateNormal];
    
   [requestDataButton setTitleColor:[UIColor grayColor] forState:UIControlStateNormal];
   [requestDataButton setBackgroundColor:[UIColor orangeColor]];
    
    [requestDataButton addTarget:self action:@selector(requestData) forControlEvents:UIControlEventTouchDown];
   [requestDataButton setFrame:CGRectMake(100, 420, 130, 80)];
    
   
    [self.view addSubview:requestDataButton];

7)用异步请求去请求并且解析 用到了SBJson第三方
-(void)requestData
{
    //创建密钥的字符串
    NSString*access_token=[[NSUserDefaults standardUserDefaults]objectForKey:@"access_token"];
   
    
    //创建一个URL...
    NSURL*url=[NSURL URLWithString:[NSString stringWithFormat:@"https://api.weibo.com/2/statuses/public_timeline.json?access_token=%@",access_token]];
   
    //创立一个request对象
    NSURLRequest*request=[NSURLRequest requestWithURL:url];
    
    //实例化一个可变的data 用来接受数据
    _data=[[NSMutableData alloc]init];
    
    //设置一个异步连接请求
    
    
    [NSURLConnection connectionWithRequest:request delegate:self];

}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    NSLog(@"hehhe");
    
}

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    //进行拼接
    
    [_data appendData:data];
    NSLog(@"=========%d",_data.length);
    
    
    
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    
    NSString*dataStr=[[NSString alloc]initWithData:_data encoding:NSUTF8StringEncoding];
    
    
    NSDictionary*dataJS=[dataStr JSONValue  ];
    NSLog(@"datajs=%@",dataJS);
    
    
}

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    
    
    NSLog(@"有错误");
    
}

8)/********
 
 重写AppDelegate 的 handleOpenURL 和 openURL 方法
 
 *********/

//写上面即可...

-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    
    
    return [WeiboSDK handleOpenURL:url delegate:self];
}

-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
    
    return [WeiboSDK handleOpenURL:url delegate:self];
}

//这个sdk里面的请求是调用了手机内的微博app .

[WBHttpRequest requestWithAccessToken:kDefineToken url:@"https://api.weibo.com/2/statuses/public_timeline.json" httpMethod:@"GET" params:nil delegate:self withTag:nil];
