当数据通过ios时,json_decode返回null

这个问题非常棘手。当我通过使用AFNetworking通过IOS传递json数据时。服务器也返回null值。但是,我用curl来测试服务器端,结果是正确的。我不知道这个问题。

这是服务器代码:

        $response['return'] = $data;

        if (get_magic_quotes_gpc()) {
            $data = stripslashes($data);
        }

        $response['sssss'] = $data;

        $data = json_decode($data, TRUE);
        $response['return json'] = $data ? $data : 'dddddddd';

        $json_errors = array(
            JSON_ERROR_NONE => 'No error has occurred',
            JSON_ERROR_DEPTH => 'The maximum stack depth has been exceeded',
            JSON_ERROR_CTRL_CHAR => 'Control character error, possibly incorrectly encoded',
            JSON_ERROR_SYNTAX => 'Syntax error',
        );
        $response['json error'] = $json_errors[json_last_error()];

        $response['p'] = $data->name;

        $response['d'] = 'test';

ios代码:

        NSURL *url = [NSURL URLWithString:@"myapi"];
        AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
        [httpClient setDefaultHeader:@"Accept" value:@"application/json"];
        [httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
        [httpClient setParameterEncoding:AFJSONParameterEncoding];

        NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:dishParameter,@"dish", nil];
        [httpClient postPath:@"dish" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {

            for (id key in responseObject) {
                NSLog(@"key:%@   value:%@", key, [responseObject objectForKey:key]);
            }


        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
             NSLog(@"error:%@",error);
        }];

响应表示没有语法错误,服务器可以获取dish参数的值。但是当$ strips通过stripslashes函数时,$ data变为null。

任何人都可以给我一些建议吗?

$data string 的类型? 为什么要从 JSON 中删除斜杠?你搞砸了语法。不要那样做。 json_decode返回null,因为它是无效的 JSON 格式。
