JSON 授权使用 NSURL 解析

Question

在下面的代码中，JSONparsing 方法工作正常，但是当我在 odataJsonParsing 方法中更改 url 时：http://192.168.1.37:8000/sap/opu/odata/sap/ZGW_BANK_DATA_SRV/BankSet? $filter=(BankCtry%20eq%20%27IN%27)&$format=json 无法加载数据，它显示为 Nil，但对于剩余的 urls，同样的方法工作正常，可以有人告诉我哪里出错了。

 **Condition**: In odataJsonParsing method have authorization credentials like.


 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: [NSURL           URLWithString:@"http://192.168.1.37:8000/sap/opu/odata/sap/ZGW_BANK_DATA_  SRV/BankSet?$filter=(BankCtry%20eq%20%27US%27)&$format=json"]]; 
    [request setHTTPMethod: @"GET"  ];
    // [request setHTTPBody:self.requestData];
     [request setValue:@"XXXXXXX" forHTTPHeaderField:@"username"];
     [request setValue:@"XXXXXXX" forHTTPHeaderField:@"password"];
     [request setValue:[[NSUserDefaults             standardUserDefaults]valueForKey:@"Auth"]     forHTTPHeaderField:@"Authorization"];
        [request setValue:@"application/json"   forHTTPHeaderField:@"Content-Type"];

   NSURL *url=[NSURL      URLWithString:@"http://jsonplaceholder.typicode.com/posts"];

   NSData  *jsonData=[[NSData alloc] initWithContentsOfURL:url];

   if(jsonData!=nil){
       NSDictionary *jsonArray=[NSJSONSerialization      JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers    error:&error];
      NSLog(@"%@",jsonArray);
    }

    }

   NSData *jsonData=[[NSData alloc] initWithContentsOfURL:[NSURL     URLWithString:@"http://192.168.1.37:8000/sap/opu/odata/sap/ZGW_BANK_DATA_    SRV/BankSet?$filter=(BankCtry%20eq%20%27IN%27)&$format=json"]];

   NSDictionary *dic=[NSJSONSerialization JSONObjectWithData:jsonData   options:NSJSONReadingMutableContainers error:&error];
   NSLog(@"%@",dic);
   }

NSURL *url = [NSURL URLWithString:@"http://192.168.1.37:8000/sap/opu/odata/sap/ZGW_BANK_DATA_SRV/BankSet?$filter=(BankCtry%20eq%20%27CH%27)&$format=json"];
 NSMutableURLRequest *request= [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:120.0];

NSString *authStr = [NSString stringWithFormat:@"%@:%@", @"abaper", @"initial@xyz"];
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodedStringWithOptions:0]];

[request setValue:authValue forHTTPHeaderField:@"Authorization"];
NSError *error ;
NSHTTPURLResponse *responseCode = nil;

NSData *oResponseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&responseCode error:&error];
if([responseCode statusCode] != 200)
{

    NSLog(@"Error getting %@, HTTP status code %li", url, (long)[responseCode statusCode]);

}
else{
    NSDictionary *responsedata = [NSJSONSerialization JSONObjectWithData:oResponseData options:NSJSONReadingAllowFragments error:&error];

    NSLog(@"%@",response data);

   }
