尝试将文件上传到 openfire 服务器时连接重置

Question

使用 XEP-0363，我想上传一个文件。 过程如下：

• 客户端发现上传功能
• 服务器响应上传功能的域
• 客户端向 xmpp 服务器请求一个插槽
• xmpp 服务器使用以下 xml 响应插槽：

<iq from='upload.montague.tld'
    id='step_03'
    to='romeo@montague.tld/garden'
    type='result'>
  <slot xmlns='urn:xmpp:http:upload:0'>
    <put url='https://upload.montague.tld/4a771ac1-f0b2-4a4a-9700-f2a26fa2bb67/tr%C3%A8s%20cool.jpg'>
      <header name='Authorization'>Basic Base64String==</header>
      <header name='Cookie'>foo=bar; user=romeo</header>
    </put>
    <get url='https://download.montague.tld/4a771ac1-f0b2-4a4a-9700-f2a26fa2bb67/tr%C3%A8s%20cool.jpg' />
  </slot>
</iq>

其中 put 和 get 中的 utls 分别是上传和下载的 url。 在那之后：

• 客户端上传文件
• 上传成功后，get url会下载文件。

现在我的问题是在上传阶段引发错误。相关代码是：

    private void apacheUpload(File file,URI url) throws Exception {
        CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpPut put = new HttpPut(url);
        FileEntity reqEntity = new FileEntity(file, ContentType.APPLICATION_OCTET_STREAM);
        put.setEntity(reqEntity);
        HttpResponse response = null;
        try {
            response = httpclient.execute(put);
        } catch (IOException e) {
            throw new Exception(e.getMessage());
        }
        if(response == null) {
            return ;
        }
        int responseCode = response.getStatusLine().getStatusCode();
        if (responseCode - 200 >= 100)
             throw new Exception("bad status code: " + responseCode);
        HttpEntity entity = response.getEntity();
        String responseString = EntityUtils.toString(entity);
        System.out.println("response");
        System.out.println(responseString);
    }

客户端错误是：

Exception in thread "main" java.lang.Exception: Connection reset
    at main.java.com.tecfrac.external.HttpFileUploadManagerUser.apacheUpload(HttpFileUploadManagerUser.java:292)
    at main.java.com.tecfrac.external.HttpFileUploadManagerUser.uploadFile(HttpFileUploadManagerUser.java:275)
    at main.java.com.tecfrac.smack.Client.uploadFile(Client.java:244)
    at main.java.com.tecfrac.smack.Client.main(Client.java:274)

服务器错误是：

        at java.lang.Thread.run(Thread.java:748) [?:1.8.0_202]

以下语句导致错误：

response = httpclient.execute(put);

先感谢您

Answer 1

openfire 火灾在另一台电脑上，所以我需要使用那台电脑的 IP 地址（不是本地主机）
