http请求出现问题。迅捷错误1200

因此基本上http请求只是停止了错误处理。 谁能解释这意味着什么?我什至不能用谷歌搜索,谢谢

我知道网址是正确的,

            let semaphore = DispatchSemaphore(value: 0)
            let session = URLSession.shared

            session.dataTask(with: request, completionHandler: { (data: Data?, response: URLResponse?, error: Error?)  in

                if let data = data
                {

                    do{
                        let json = try JSONSerialization.jsonObject(with: data, options: .allowFragments)
                        print(json)
                        let results = try decoder.decode(decode.self, from: data)
                        result = results
                        semaphore.signal()
                    } catch {
                        print(error)
                    }
                }
            }).resume()
            semaphore.wait()

        if result != nil{
               return result
        }
        else {return nil}
