如何在 alamofire 中將 pdf 文件作為多部分表單數據上傳？

Question

我必須上傳 pdf 文件作為多部分表單數據。
我讀了 Alamofire/Usage.md（上傳數據到服務器）

所以我寫了下面的代碼。

extension ViewController: UIDocumentPickerDelegate {

    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
        guard let url = urls.first else { return }
        print(url) // file:///private/var/mobile/Containers/Data/Application/69C5B45A-AA29-46D2-909C-2A1A5A68C10F/tmp/com.test.test-Inbox/D5100_EN.pdf
        do {
            let data = try Data(contentsOf: url)
            print(data) // 10899227 bytes
            AF.upload(multipartFormData: { multipartFormData in
                multipartFormData.append(data, withName: "pdf")
            }, to: "https://myurl.com")
                .responseJSON { response in
                    debugPrint(response) // message = "Required request part 'file' is not present"
            }
        } catch {
            print(error)
        }
    }

}

但它被歸檔了。

Answer 1

您需要指定mimeType ：

multipartFormData.append(pdfData, withName: "pdfDocuments", fileName: "pdf", mimeType:"application/pdf")

更新

根據錯誤，您必須了解服務器期望名稱為“file”的 pdf

嘗試這個：

 multipartFormData.append(pdfData, withName: "file", fileName: "file", mimeType:"application/pdf")

Answer 2

您可能需要指定MimeType 。 嘗試將您的請求更新為

AF.upload(multipartFormData: { multipartFormData in
    multipartFormData.append(data, withName: "name", fileName: "fileName", mimeType: "application/pdf")
}, to: "https://myurl.com")
    .responseJSON { response in
        debugPrint(response) // message = "Required request part 'file' is not present"
}
