Alamofire后台提取不會處理更多請求

Question

我想用performFetchWithCompletionHandler執行后台提取，顯然所有以前的解決方案都不適用於我。

奇怪的是我的第一個要求是好的，但接下來的要求不是。

我嘗試使用SessionManager的單例，我也嘗試將所有Alamofire請求出列到后台線程，並使用URLSessionConfiguration.background(withIdentifier: "com.test.background")更改了URLSessionManager 。

 group.enter()
 api.getClimateStateData(carId: carId, completion: { [weak self] response in
       guard let strongSelf = self else { return }
       climateModel = strongSelf.sortDataFromError(data: response)
       group.leave()
})

func getClimateStateData(carId: Int, completion: @escaping (ServiceResponse<ClimateStateModel>) -> Void) {
        let header: HTTPHeaders = ["User-Agent": UserAgentHelper.fullUserAgentString]
        request("/api/1/vehicles/\(carId)/data_request/climate_state", method: .get, parameters: nil, encoding: nil, headers: header).responseData { [weak self] response in
            guard let strongSelf = self else { return }
            completion(strongSelf.completionResponse(response))
     }
}

    @discardableResult private func request(
        _ path: String,
        method: HTTPMethod,
        parameters: Parameters? = nil,
        encoding: ParameterEncoding? = nil,
        headers: HTTPHeaders? = nil)
        -> DataRequest {
            let userEncoding = encoding ?? self.defaultEncoding
            print("Asking: " + path)
            return Service.sessionManager2.request("\(API)\(path)", method: method, parameters: parameters, encoding: userEncoding, headers: headers).validate()
}

我想滿足這些要求。

謝謝你的時間！

我的壞，這是由於self =零。

由於某些原因， self是deinit。
