本文介绍如何使用Java的HttpClient进行文件上传操作。通过创建HttpClient实例，并设置HttpPost请求到指定URL，然后利用FileInputStream读取本地文件，将文件内容封装为InputStreamEntity进行发送。最后消费响应内容并关闭连接。

HttpClient httpclient = new DefaultHttpClient();


HttpPost httppost = new HttpPost("http://localhost/upload");


File file = new File("/path/to/myfile");

FileInputStream fileInputStream = new FileInputStream(file);

InputStreamEntity reqEntity = new InputStreamEntity(fileInputStream, file.length());


httppost.setEntity(reqEntity);

reqEntity.setContentType("binary/octet-stream");

HttpResponse response = httpclient.execute(httppost);

HttpEntity responseEntity = response.getEntity();


if (responseEntity != null) {

  responseEntity.consumeContent();

}


httpclient.getConnectionManager().shutdown();
