NSURLSession 403 响应

Question

我正在使用 NSURLSession 发送 HTTP Post 请求。虽然它没有给出错误，但我在完成处理程序中得到了空响应。请帮我弄清楚我在这里做错了什么。

我的 Url 请求如下所示

- (void)testUrl {

    NSError *error;
    NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];

    NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];

   NSURL * url = [NSURL URLWithString:[NSString stringWithFormat:@"http://192.168.100.4.8080/proposals/addProposal/forJobId/77"]];
    NSLog(@"url : %@",url);
    NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];

    NSMutableDictionary *params = [NSMutableDictionary new];
    [params setValue:[NSString stringWithFormat:@"%d",500] forKey:@"offeredQuote"];
    [params setValue:@"2016-09-01T12:25:56.000Z" forKey:@"offeredTimeline"];
    [params setValue:@"2016-08-31T12:26:08.876Z" forKey:@"postingTime"];
    [params setValue:@"cohcih khccoh" forKey:@"proposalDescription"];
    [params setValue:[NSString stringWithFormat:@"%d",122] forKey:@"userID"];


    NSLog(@"params : %@",params);
    [urlRequest addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [urlRequest addValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [urlRequest setHTTPMethod:@"POST"];

    NSData *postData = [NSJSONSerialization dataWithJSONObject:params options:0 error:&error];
    [urlRequest setHTTPBody:postData];

    dataTask =[defaultSession dataTaskWithRequest:urlRequest
                                completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
                                    NSLog(@"response : %@",response);
                                    NSLog(@"data : %@", data);
                                    if(error == nil)
                                    {
                                        NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];

                                        NSError *jsonError;
                                        NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:data
                                                                                                   options:kNilOptions
                                                                                                     error:&jsonError];
                                        NSLog(@"json object ; %@",jsonObject);
                                        NSLog(@"json text ; %@",text);
                                    }
                                    else{
                                        NSLog(@"erro : %@",error);
                                    }
                                }];
    [dataTask resume];
}

我收到这样的回复

    Date = "Wed, 31 Aug 2016 17:30:08 GMT";

    Vary = "Accept-Encoding";
} }

真是个愚蠢的错误。我改变了基础 url http://192.168.100.4.8080 为此 http://192.168.100.4:8080 并且它开始工作了。如果有人遇到类似问题，请检查您的 url 和参数。此错误与服务器授权有关。很可能 url.
