iOS Facebook FQL问题

我正在尝试让以下FQL语句在我的iOS应用程序中工作

SELECT comment_info,likes,share_count FROM stream WHERE post_id

出于某种原因，我一直从graph API中得到一个错误

分析错误：位置70处的意外“？”OAuth异常

由于某种原因，该职位会移动，因此会在我的请求末尾添加一个“？”？下面是我正在使用的代码块。现在让我抓狂，因为我已经尝试了很多东西，但仍然无法摆脱这个问题，但是使用相同的方法拉/me/home时效果很好

        NSLog(@"ID: %@", graphID);

        NSString* urlText = [NSString stringWithFormat: @"https://graph.facebook.com/fql?q=SELECT comment_info,likes,share_count FROM stream WHERE post_id = '%@'", graphID];
        urlText = [urlText stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        NSURL *url = [NSURL URLWithString: urlText];

        SLRequest * request = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:url parameters: nil];
        request.account = self.facebookAccount;

        [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
            NSLog(@"url %@", request.URL.absoluteURL);
            NSString * responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
            NSError* responseError;

            NSDictionary* jsonDict = [NSJSONSerialization JSONObjectWithData:[responseString dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&responseError];
            NSArray * dataArray = jsonDict[@"data"];

            [dataArray enumerateObjectsUsingBlock:^(NSDictionary * infoDictionary, NSUInteger idx, BOOL *stop) {
                NSNumber *likesCount;
                NSNumber *commentsCount;

                likesCount = [NSNumber numberWithInt: [infoDictionary[@"likes"][@"count"] integerValue]];
                commentsCount = [NSNumber numberWithInt: [infoDictionary[@"comment_info"][@"comment_count"] integerValue]];

                NSLog(@"likes %@", likesCount);
            }];
        }];

我建议您使用带有'q'参数的NSDictionary，如下所示

NSDictionary *params = @{ @"q" : [NSString stringWithFormat: @"https://graph.facebook.com/fql?q=SELECT comment_info,likes,share_count FROM stream WHERE post_id = '%@'", graphID] };

并根据您的请求将其作为参数发送。

这是正确的方法

NSString* urlString = @"https://graph.facebook.com/fql";
urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString* query = [NSString stringWithFormat:@"SELECT user_id FROM like WHERE post_id='%@' AND user_id=me()", postId];
SLRequest* request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                        requestMethod:SLRequestMethodGET
                                                  URL:[NSURL URLWithString:urlString]
                                           parameters:@{@"q" : query}];

request.account = <account>;

NSString*urlString=@”https://graph.facebook.com/fql";
urlString=[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]；
NSString*query=[NSString stringWithFormat:@“从post_id='%@'和user_id=me（）”中选择用户_id，postId]；
SLRequest*request=[SLRequestRequestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:[NSURL URLWithString:urlString]
参数：@{@“q”：query}]；
request.account=；

试试这个

NSString*urlString=@

urlString=[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]

NSString*query=[NSString stringWithFormat:@“选择评论\信息，喜欢，共享\来自流的计数，其中post\ id='%@'，graphID]

SLRequest*request=[SLRequestRequestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:urlString] 参数：@{@“q”：query}]

request.account=self.facebookAccount;
[request performRequestWithHandler:^(NSData *data, NSHTTPURLResponse *response, NSError *error)

 {
     if(!error)
     {

         NSDictionary *list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
        NSLog(@data from facebook : %@“,list);
     }
     else
     {

         NSLog(@"error while fetching data from facebook : %@",error);
     }


 }];

NSLog中也没有显示“？”（@“url%@”，request.url.absoluteURL）；
