java 中HttpClient传输xml字符串实例详解
java 中HttpClient传输xml字符串实例详解
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
POM文件依赖配置
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.2</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpmime</artifactId> <version>4.5.2</version> </dependency> <dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.2.4</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.xwiki.platform</groupId> <artifactId>xwiki-platform-rest-model</artifactId> <version>7.2</version> </dependency> </dependencies>
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)); } }
