java 中HttpClient傳輸xml字符串實例詳解
介紹:我現(xiàn)在有一個對象page,需要將page對象轉(zhuǎn)換為xml格式并以binary方式傳輸?shù)椒?wù)端
其中涉及到的技術(shù)點有:
1、對象轉(zhuǎn)xml流
2、輸出流轉(zhuǎn)輸入流
3、httpClient發(fā)送二進(jìn)制流數(shù)據(jù)
POM文件依賴配置

java代碼示例
public void testNewPage() throws Exception{ //定義對象 Page page =new Page(); page.setTitle("testPage"); page.setSyntax("xwiki/2.0"); page.setContent("This is a testPage"); page.setId("xwiki:Main.testPage"); //初始化并轉(zhuǎn)換對象為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 ); //將流轉(zhuǎn)換并放入到InputStreamEntity中 InputStreamEntity inputStreamEntity=new InputStreamEntity(new ByteArrayInputStream(out.toByteArray())); //發(fā)送請求 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(); //獲取返回結(jié)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)); } }
