java - 使用 HttpClient 写入正文请求

Question

我想用 XML 内容类型编写请求的正文，但我不知道如何使用 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，则可以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());
    }

注意异常。

BTW，例子是httpclient 4.x版本写的

扩展您的代码（假设您要发送的 XML 在xmlString）：

String xmlString = "</xml>";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpRequest = new HttpPost(this.url);
httpRequest.setHeader("Content-Type", "application/xml");
StringEntity xmlEntity = new StringEntity(xmlString);
httpRequest.setEntity(xmlEntity );
HttpResponse httpresponse = httpclient.execute(httppost);
