iOS - 来自 ARC 和解析中单个 API 的不同响应

Question

在我的项目中，我传递了这个 API:http://dev-demo.info.bh-in-15.webhostbox.net/dv/nationalblack/api/businessbysubcat参数:prod_id=25,var_id=140。问题是当我在 Rest Client 中传递此 api 时它显示正确的响应但是当我尝试将它放入我的代码时它显示不同的响应。

我正在使用以下代码:

-(void)listofNotice
{
    NSString *post = [NSString stringWithFormat:@"prod_id=25,var_id=140"];
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

    [request setURL:[NSURL URLWithString:@"http://dev-demo.info.bh-in-15.webhostbox.net/dv/nationalblack/api/businessbysubcat"]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSURLResponse *response;
    NSError *err;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

    //NSString *str=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
    //NSLog(@"str : %@",str);

    NSDictionary *dict6 = [self cleanJsonToObject:responseData];
    NSLog(@"str : %@",dict6);

}


- (id)cleanJsonToObject:(id)data
{
    NSError* error;
    if (data == (id)[NSNull null])
    {
        return [[NSObject alloc] init];
    }
    id jsonObject;
    if ([data isKindOfClass:[NSData class]])
    {
        jsonObject = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
    }
    else
    {
        jsonObject = data;
    }
    if ([jsonObject isKindOfClass:[NSArray class]])
    {
        NSMutableArray *array = [jsonObject mutableCopy];
        for (int i = (int)array.count-1; i >= 0; i--)
        {
            id a = array[i];
            if (a == (id)[NSNull null])
            {
                [array removeObjectAtIndex:i];
            } else
            {
                array[i] = [self cleanJsonToObject:a];
            }
        }
        return array;
    }
    else if ([jsonObject isKindOfClass:[NSDictionary class]])
    {
        NSMutableDictionary *dictionary = [jsonObject mutableCopy];
        for(NSString *key in [dictionary allKeys])
        {
            id d = dictionary[key];
            if (d == (id)[NSNull null])
            {
                dictionary[key] = @"";
            } else
            {
                dictionary[key] = [self cleanJsonToObject:d];
            }
        }
        return dictionary;
    }
    else
    {
        return jsonObject;
    }
}

它显示以下响应:

str : {
    business = 0;
    "business-list" = "Business list empty.";
    response = 401;
}

但实际的响应是这样的

请帮助我..提前致谢

请更改此

NSString *post = [NSString stringWithFormat:@"prod_id=25,var_id=140"];

收件人:

NSString * post =[NSString stringWithFormat:@"prod_id=25&var_id=140"];

如果可能的话使用这个:

    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
        configuration.HTTPAdditionalHeaders = @{@"application/x-www-form-urlencoded" :  @"Content-Type"};
        NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
        NSURL *url = [NSURL URLWithString:@"http://dev-demo.info.bh-in-15.webhostbox.net/dv/nationalblack/api/businessbysubcat"];
        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

      NSData *requestData = [post dataUsingEncoding:NSUTF8StringEncoding];
      [request setHTTPMethod:@"POST"];
      [request setHTTPBody:requestData];

      NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)                                                                              {   
  if (data != nil){
    NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
    NSInteger code = [httpResponse statusCode];
    NSLog(@"Status Code: %ld", (long)code);

  if (code == 200) {
    NSError *error;
    id responseObject =[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
   }
  }                                                                              
}];

[postDataTask resume];

或

    NSString *postString = [NSString stringWithFormat:@"prod_id=%@&var_id=%@",@"25",@"140"];
    NSURL *urlPath = [NSURL URLWithString:@"http://dev-demo.info.bh-in-15.webhostbox.net/dv/nationalblack/api/businessbysubcat"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlPath
                                                           cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30.0];

    NSData *requestData = [postString dataUsingEncoding:NSUTF8StringEncoding];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:requestData];
    [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
        [APP_DELEGATE removeLoader];

        if(data != nil) {
            NSDictionary *responseObject =[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
            NSLog(@" %@", responseObject);
        }
        else {
        }
    }];

希望这对您有所帮助。
