使用 HttpClient 写入正文请求

我想用 XML 内容类型编写请求正文，但我不知道如何使用 HttpClient 对象（http://hc.apache.org/httpclient-3.x/apidocs/index.html http://hc.apache.org/httpclient-3.x/apidocs/index.html )

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpRequest = new HttpPost(this.url);
httpRequest.setHeader("Content-Type", "application/xml");

我不知道如何继续用我的 XML 编写正文......

如果你的xml是这样写的java.lang.String你可以只使用HttpClient这样

    public void post() throws Exception{
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("http://www.baidu.com");
        String xml = "<xml>xxxx</xml>";
        HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        String result = EntityUtils.toString(response.getEntity());
    }

注意例外情况。

顺便说一句，该示例是由 httpclient 版本 4.x 编写的
