java 中HttpClient传输xml字符串实例详解
网站建设哪家好，找创新互联！专注于网页设计、网站建设、微信开发、小程序设计、集团企业网站建设等服务项目。为回馈新老客户创新互联还提供了佳县免费建站欢迎大家使用！
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
junit junit 3.8.1 test org.apache.httpcomponents httpclient 4.5.2 org.apache.httpcomponents httpmime 4.5.2 commons-lang commons-lang 2.4 com.google.code.gson gson 2.2.4 jar compile org.xwiki.platform xwiki-platform-rest-model 7.2
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));
}
}
