【问题描述】：
使用 XEP-0363，我想上传一个文件。流程如下：
- 客户端发现上传功能
- 服务器以上传功能的域响应
- 客户端向 xmpp 服务器请求一个槽
- 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。 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抛出错误。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

服务器错误是：

以下语句导致错误：
response = httpclient.execute(put);
提前谢谢你
