如何在 Restful 网络服务中发送 XML 文件端点 url

Question

我需要将请求 XML 文件作为多部分表单数据发送到 {url}。这在 Restful 网络服务中是如何做到的。在我在那里使用之前，

RequestDispatcher rd = request.getRequestDispatcher("/file/message.jsp");
rd.forward(request, response);

但这不是具体发送的{url}，如何发送？

Answer 1

如果可以（取决于您的上下文），使用 JAX-RS 客户端是一种解决方案。

Apache CXF 示例：

InputStream inputStream = getClass().getResourceAsStream("/file/message.jsp");
WebClient client = WebClient.create("http://myURL");
client.type("multipart/form-data");
ContentDisposition cd = new ContentDisposition("attachment;filename=message.jsp");
Attachment att = new Attachment("root", inputStream, cd);
client.post(new MultipartBody(att));

我认为 Web 服务不是您的最佳选择
您可以尝试原生流，然后您可以在这里编写 header 和 body示例代码来解释我的观点

Socket socket=new new socket(InetAddress.getByName("whosebug.com"), 80);
// just the host and the port
Writer out = new OutputStreamWriter(socket.getOutputStream(),"UTF-8");
            out.write("POST http://" + HOST + ":" + port+ "/ HTTP/1.1\r\n");//here u can insert your end point or the page accepts the xml msg
    out.write("Host: " + HOST + "/ \r\n");
    out.write("Content-type: application/xml,text/xml\r\n");// Accept
    out.write("Content-length: " + req.length() + "\r\n");
    out.write("Accept:application/xml,text/xml\r\n");
    out.write("\r\n");
    // req the Request Body or the xml file to be sent
    out.write(req);//
    out.flush();`

您可以使用 Jersey Rest Client 以 post request 的形式发送您的 XML 消息。

try {
    Client client = Client.create();

    WebResource webResource = client.resource(http://<your URI>);

    // POST method
    ClientResponse response = webResource.accept("multipart/form-data").type("multipart/form-data").post(ClientResponse.class, "<your XML message>");

    // check response status code
    if (response.getStatus() != 200) {
        throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
    }

    // display response
    String output = response.getEntity(String.class);
    System.out.println("Output from Server .... ");
    System.out.println(output + "\n");
} catch (Exception e) {
     e.printStackTrace();
}
