【问题描述】：

我无法使用 smack 客户端 android 在 xmpp 上上传文件。 slot.puturl() 返回“https://localhost:7443/httpfileupload/27c97df7-dbbf-47ff-b19a-3ac624e51cf0/1.jpg”

 HttpFileUploadManager manager = HttpFileUploadManager.getInstanceFor(mConnection);
    try {
        Slot slot = manager.requestSlot(path, 10000);

        uploadFileToSlot(new File(path), slot);
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (XMPPException.XMPPErrorException e) {
        e.printStackTrace();
    } catch (SmackException e) {
        e.printStackTrace();
    }

【解决方案1】：

你可以试试这个代码。

    FileTransferManager ftm1 = FileTransferManager.getInstanceFor(connection);
    FileTransferManager ftm2 = FileTransferManager.getInstanceFor(connection2);

    ftm2.addFileTransferListener(new FileTransferListener() {
        @Override
        public void fileTransferRequest(FileTransferRequest request) {
            IncomingFileTransfer ift = request.accept();
            try {
                InputStream is = ift.recieveFile();
                ByteArrayOutputStream os = new ByteArrayOutputStream();
                int nRead;
                byte[] buf = new byte[1024];
                while ((nRead = is.read(buf,  0, buf.length)) != -1) {
                    os.write(buf, 0, nRead);
                }
                os.flush();
                dataReceived = os.toByteArray();
            } catch (SmackException | IOException | XMPPErrorException e) {
                e.printStackTrace();
            }
            if (Arrays.equals(dataToSend, dataReceived)) {
                System.out.println("Received data matches send data. \\o/");
            } else {
                System.err.println("Recieved data DOES NOT match send data. :(");
            }
        }
    });

    OutgoingFileTransfer oft = ftm1.createOutgoingFileTransfer(XmppStringUtils.completeJidFrom(USER, SERV, "resourse"));
    oft.sendStream(new ByteArrayInputStream(dataToSend), "hello.txt", dataToSend.length, "A greeting");
    outerloop: while (!oft.isDone()) {
        switch (oft.getStatus()) {
        case error:
            System.out.println("Filetransfer error: " + oft.getError());
            break outerloop;
        default:
            System.out.println("Filetransfer status: " + oft.getStatus() + ". Progress: " + oft.getProgress());
            break;
        }
        Thread.sleep(1000);
    }

    connection.disconnect();
    connection2.disconnect();
    Thread.sleep(1000);
}

【解决方案2】：

经过深入研究，我得到了解决方案。

HttpFileUploadManager 仅用于向服务器请求插槽。

一旦您使用 httpclient 或 okhttpclient 获得插槽请求 url 上传文件。对于okhttpclient：

您需要通过mtm或certificatepinning配置sslSocketFactory。

OkHttpClient.Builder okHttpClientBuilder = new OkHttpClient().newBuilder();
SSLContext sslContext = JavaPinning.forPin(<PINNING_VALUE>);
okHttpClientBuilder.writeTimeout(5, TimeUnit.MINUTES)
    .connectTimeout(5, TimeUnit.MINUTES)
    .readTimeout(5, TimeUnit.MINUTES);

okHttpClientBuilder.sslSocketFactory(sslContext.getSocketFactory(), JavaPinning.trustManagerForPin(<PINNING_VALUE>));
OkHttpClient client = okHttpClientBuilder.build();

启动okhttpclient并添加类似文件。

Request request = new Request.Builder()
    .url(slot.getPutUrl())
    .put(RequestBody.create(MediaType.parse("application/octet-stream"), files))
        .build();

现在开始上传。

client.newCall(request).enqueue(new Callback() {

    @Override
    public void onFailure(final Call call, final IOException e) {
        // Handle the error
        Log.i(log, "error " + e);
    }

    @Override
    public void onResponse(final Call call, final Response response) throws IOException {
        if (!response.isSuccessful()) {
            // Handle the error
            Log.i(log, "errored " + response);
        }
        Log.i(log, "success " + response);
        // Upload successful
    }
});

希望对你有帮助。
