Jersey REST客户端：如何将XML文件添加到POST请求的正文中？

Question

到目前为止，我的代码：

FileReader fileReader = new FileReader("filename.xml");
Client c = Client.create();
WebResource webResource = c.resource("http://localhost:8080/api/resource");
webResource.type("application/xml");

我想发送filename.xmlwith
POST方法的内容，但是我不知道如何将它们添加到请求的正文中。我需要帮助，因为在网络上，我只能找到如何添加Formargs。

提前致谢。

您始终可以在Java SE中使用java.net API：

URL url = new URL("http://localhost:8080/api/resource");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/xml");

OutputStream os = connection.getOutputStream();

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
FileReader fileReader = new FileReader("filename.xml");
StreamSource source = new StreamSource(fileReader);
StreamResult result = new StreamResult(os);
transformer.transform(source, result);

os.flush();
connection.getResponseCode();
connection.disconnect();
