1.AFNetworking框架处理用户一般的POST GET等5种类型的请求

GET请求：

AFHTTPRequestOperationManager *mgr=[AFHTTPRequestOperationManager manager];
    
    NSMutableDictionary *params=[NSMutableDictionary dictionary];
    [params setObject:account.access_token forKey:@"access_token"];
    
    [mgr GET:@"https://api.weibo.com/2/statuses/friends_timeline.json" parameters:params success:^(AFHTTPRequestOperation *operation, NSDictionary *responseObject) {
        
        NSArray *newStatus=[WBStatus objectArrayWithKeyValuesArray:responseObject[@"statuses"]];
        NSIndexSet *set=[[NSIndexSet alloc] initWithIndexesInRange:NSMakeRange(0, newStatus.count)];
        [self.statues insertObjects:newStatus atIndexes:set];
        [self.tableView reloadData];
        
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"%@",[error localizedDescription]);
    }];

AFHTTPRequestOperationManager *mgr=[AFHTTPRequestOperationManager manager];
    
    NSMutableDictionary *param=[NSMutableDictionary dictionary];
    [param setObject:@"43435345453 forKey:@"client_id"];
    [param setObject:@"354083454f535fv53c53d97" forKey:@"client_secret"];
    [param setObject:@"authorization_code" forKey:@"grant_type"];
    [param setObject:@"http://www.baidu.com" forKey:@"redirect_uri"];
    [param setObject:code forKey:@"code"];
    

    [mgr POST:@"https://api.weibo.com/oauth2/access_token" parameters:param success:^(AFHTTPRequestOperation *operation, NSDictionary *responseObject) {
        
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        
    }];
