ios - 错误域=NSURLErrorDomain Code=-1017 "The operation couldn’ t be

Question

我刚开始 ios 开发，我正在尝试与我的 api 交换数据。当我执行 POST 请求时一切正常，但是当我尝试执行 GET 请求时出现以下错误:

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.)"}

有人能解释一下出了什么问题以及我该如何解决吗？

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:
    }
}

如果您忘记提及 HTTPMethod，也会发生错误，我遇到了问题“NSURLErrorDomain Code=-1017”，不知何故我忘记添加行“request.HTTPMethod =”POST”。

添加该行后，我的代码运行完美。
