HttpClient 传输xml字符串

介绍：我现在有一个对象page，需要将page对象转换为xml格式并以binary方式传输到服务端

其中涉及到的技术点有：

1、对象转xml流

2、输出流转输入流

3、httpClient发送二进制流数据

java代码示例

public void testNewPage() throws Exception{
        //定义对象
        Page page =new Page();
        page.setTitle("testPage");
        page.setSyntax("xwiki/2.0");
        page.setContent("This is a testPage");
        page.setId("xwiki:Main.testPage");
        //初始化并转换对象为xml文件的流
        JAXBContext context = JAXBContext.newInstance("org.xwiki.rest.model.jaxb");
        Marshaller marshaller=context.createMarshaller();
        Unmarshaller unmarshaller = context.createUnmarshaller();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        marshaller.marshal( page, out );
        //将流转换并放入到InputStreamEntity中
        InputStreamEntity inputStreamEntity=new InputStreamEntity(new ByteArrayInputStream(out.toByteArray()));

        //发送请求
        CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpUriRequest httpPost = RequestBuilder.put()
                .setUri(new URI("http://172.16.200.220:8082/xwiki/rest/wikis/xwiki/spaces/Main/pages/testPage"))
                .setEntity(inputStreamEntity)
                .setHeader("Content-Type", "application/xml")
                .setHeader("Cookie", cookieStr).build();
        //获取返回结果
        CloseableHttpResponse response = httpclient.execute(httpPost);
        System.out.println(response.getStatusLine().getStatusCode());
        HttpEntity responseEntity=response.getEntity();
        System.out.println(responseEntity);
        if(response.getStatusLine().getStatusCode()<400){
            Page responsePage = (Page) unmarshaller.unmarshal(responseEntity.getContent());
            System.out.println(responsePage);
//            System.out.println(new Gson().toJson(responsePage));
        }
    }
