错误域= NSURLErrorDomain代码= -1017“操作不能

我刚刚开始ios开发，我正在尝试与我的api交换数据。当我正在进行POST请求时一切正常，但当我尝试执行GET请求时，我收到以下错误：

I just started ios development and I'm trying to exchange data with my api. When I'm doing POST requests everything is going fine but when I'm trying to do a GET request I get the following error:

错误域= NSURLErrorDomain代码= -1017操作不能完成
。（NSURLErrorDomain错误-1017。）UserInfo = 0x145a2c00
{NSErrorFailingURLStringKey = http://myAPI.com/ ，
_kCFStreamErrorCodeKey = -1，NSErrorFailingURLKey = http://myAPI.com ，
_kCFStreamErrorDomainKey = 4，NSUnderlyingError = 0x145b21d0操作无法完成。（kCFErrorDomainCFNetwork错误
-1017。）}

Error Domain=NSURLErrorDomain Code=-1017 "The operation couldn’t be completed. (NSURLErrorDomain error -1017.)" UserInfo=0x145a2c00 {NSErrorFailingURLStringKey=http://myAPI.com/, _kCFStreamErrorCodeKey=-1, NSErrorFailingURLKey=http://myAPI.com, _kCFStreamErrorDomainKey=4, NSUnderlyingError=0x145b21d0 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1017.)"}

有人可以解释出现了什么问题以及如何解决这个问题吗？

Could someone explain what's going wrong and how I can fix it?

我的要求：

-(void)hitApiWithURL:(NSString*)url HTTPMethod:(NSString*)HTTPMethod params:(NSDictionary*)params successBlock:(successTypeBlock)success  failureBlock:(errorTypeBlock)failure{


    NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfig delegate:self delegateQueue:nil];


    [sessionConfig setHTTPAdditionalHeaders:@{@"Content-type": @"application/json"}];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
    [request setHTTPMethod:HTTPMethod];

    // The body
    NSError *error = nil;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:params options:0 error:&error];
    [request setHTTPBody:jsonData];


    NSURLSessionDataTask *dataTaks = [session dataTaskWithRequest:request];
    [dataTaks resume];

    NSLog(@"dataTask started");

}


- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task
didCompleteWithError:(NSError *)error {
    if (error) {
        //Gives my error
    }
    else {
        // do something:
    }
}
