用HttpClient编写正文请求

Question

我想用XML内容类型编写请求的正文，但是我不知道如何使用HttpClient对象（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");

而且我不知道如何继续用我的XML编写正文…

Answer 1

如果您的xml是由java.lang.String您编写的，则只能HttpClient以这种方式使用

    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。

顺便说一句，该示例是由httpclient版本4.x编写的
