RxSwift URLSession请求已释放

import RxSwift

func makeRequest() -> Observable<Data> {
    return Observable.create { observer in
        let task = URLSession.shared.dataTask(with: URL(string: "https://example.com")!) { data, response, error in
            if let error = error {
                observer.onError(error)
            } else if let data = data {
                observer.onNext(data)
                observer.onCompleted()
            }
        }
        task.resume()

        // 在这里释放请求资源
        return Disposables.create {
            task.cancel()
        }
    }
}

// 使用示例
let disposeBag = DisposeBag()

makeRequest()
    .subscribe(onNext: { data in
        // 处理请求成功的数据
    }, onError: { error in
        // 处理请求失败的错误
    })
    .disposed(by: disposeBag)
