Write in body request with HttpClient

Question

I want to write the body of a request with XML content-type but I don't know how with HttpClient Object ( 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");

And I don't know how to continue to write the body with my XML ...

If your xml is written by java.lang.String you can just using HttpClient in this way

    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());
    }

pay attention to the Exceptions.

BTW, the example is written by the httpclient version 4.x

I would suggest using `java.nio.charset.StandardCharsets`, and modify the `ByteArrayEntity` line into: HttpEntity entity = new ByteArrayEntity(xml.getBytes(StandardCharsets.UTF_8)); – MrMister Aug 29 '16 at 11:23

Instead of `new ByteArrayEntity(xml.getBytes("UTF-8"));` use `new StringEntity(xml, ContentType.APPLICATION_XML);` – Asaph Oct 26 '16 at 22:56
Using new StringEntity may result in the incorrect charset declared in the header. Use with care. – Jeremy Brooks Apr 20 '17 at 20:32

Should use [HttpClientBuilder.create().build()](https://stackoverflow.com/a/32372938) instead since `DefaultHttpClient` is deprecated. – neuront Feb 05 '18 at 04:48
I am hitting an endpoint that is created by me only on another Spring boot application and it is a post method but it is giving error as request body not found. I implemented the answer. I don't know what else to do. – Drishti Jain Nov 24 '22 at 09:18

Extending your code (assuming that the XML you want to send is in 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);
