Question

我尝试使用NSURLSession的过程并不顺利：How to download PDF use NSURLSession POST with headers and body parameters? 。因此我尝试使用Alamofire，但始终失败。这是我的代码：

func callAPIMoneyReport() {
    let param = HTTPBody.moneyReportBody(contactId: contactIdentifier!)
    print("param: \(String(describing: param))")

    let url = NSURL(string:Constant.getAPIMONEYReport())
    print("MONEY REPORT URL:\(String(describing: url!))")

    Alamofire.request(Constant.getAPIMONEYReport(), method: .post, parameters: param, encoding: JSONEncoding.default, headers: ConnectionManager.sharedIns.getHTTPHeadersRefreshToken())
        .responseObject{ (response: DataResponse<MainResponse>) in
            switch(response.result) {
            case .success(_):
                print("MONEY report success")
                if response.result.value != nil {
                    self.moneyReportModel = response.result.value
                    let status = self.moneyReportModel?.status
                    let statusCode = response.response?.statusCode
                    print("statusCode:\(String(describing: statusCode))")
                    if(statusCode == 200){

                    }else{
                        AlertViewUtil.sharedIns.showAlertFeedback(self, messageText: status!, actionButton1: Wordings.BTN_CLOSE, actionButton2: "")
                    }
                }
                break

            case .failure(_):
                print("MONEY report failure")
                break

            }
    }
}

更新：尝试使用此代码成功，但无法下载PDF：

Alamofire.request(Constant.getAPIMONEYReport(), method: .post, parameters: param, encoding: JSONEncoding.default, headers: ConnectionManager.sharedIns.getHTTPHeadersRefreshToken())
        .responseData { response in
            print("request:\(request)")
            print("response:\(response.data!)")
    }

更新也请尝试使用此代码，但找不到pdf：

let destination: DownloadRequest.DownloadFileDestination = { _, _ in
        let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0];
        let fileURL = documentsURL.appendingPathComponent("family-money.pdf")
        return (fileURL, [.removePreviousFile, .createIntermediateDirectories])
    }

    Alamofire.download(Constant.getAPIMONEYReport(), method: .post, parameters: param, encoding: JSONEncoding.default, headers: ConnectionManager.sharedIns.getHTTPHeadersRefreshToken(), to: destination)
        .response { result in
            self.dismissProgressDialog()
            if let error = result.error {
                print("MONEY report failure")
            } else {
                print("MONEY report success")
                let vc = UIDocumentInteractionController(url: result.destinationURL!)
                vc.delegate = self
                vc.presentPreview(animated: true)
            }
    }

获取PDF的正确代码是什么？更新就可以了，因为忘了输入以下代码：

vc.name = result.destinationURL!.lastPathComponent

Alamofire POST下载PDF
