使用java发布xml数据

Question

我使用以下java代码将xml数据POST到远程url并获取响应.在这里,我使用xml文件作为输入.我需要的是将xml作为字符串传递而不是文件...无论如何我能做到这一点吗？有人能帮我吗？非常感谢!

Java代码

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.PostMethod;

public class xmlToString {

public static void main(String[] args) {
    String strURL = "https://simulator.expediaquickconnect.com/connect/ar";
    String strXMLFilename = "xmlfile.xml";
    File input = new File(strXMLFilename);
    PostMethod post = new PostMethod(strURL);
    try {
        post.setRequestEntity(new InputStreamRequestEntity(
                new FileInputStream(input), input.length()));
        post.setRequestHeader("Content-type",
                "text/xml; charset=ISO-8859-1");
        HttpClient httpclient = new HttpClient();

        int result = httpclient.executeMethod(post);
        System.out.println("Response status code: " + result);
        System.out.println("Response body: ");
        System.out.println(post.getResponseBodyAsString());
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        post.releaseConnection();
    }
}

   }

更新:我需要将XML作为字符串传递并删除涉及xml文件...

org.apache.commons.httpclient.methods.PostMethod上的setRequestEntity方法有一个重载版本,它接受StringRequestEntity作为参数.如果您希望将数据作为字符串传递(而不是输入流),则应使用此方法.所以你的代码看起来像这样:

String xml = "whatever.your.xml.is.here";
PostMethod post = new PostMethod(strURL);     
try {
    StringRequestEntity requestEntity = new StringRequestEntity(xml);
    post.setRequestEntity(requestEntity);
....

希望有所帮助.
