Apache HttpClient 是一个功能强大的 Java 库,用于执行 HTTP 请求。下面是如何使用 Apache HttpClient 发送 XML POST 请求的步骤:
HTTP POST 请求是一种向服务器提交数据的方法,常用于提交表单数据或上传文件。当需要发送 XML 数据时,可以通过 POST 方法将 XML 内容作为请求体发送到服务器。
以下是一个使用 Apache HttpClient 发送 XML POST 请求的示例代码:
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
public class XmlPostExample {
public static void main(String[] args) {
try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
HttpPost httpPost = new HttpPost("http://example.com/api");
httpPost.setHeader("Content-Type", "application/xml");
String xmlData = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<request>\n" +
" <data>Sample XML Data</data>\n" +
"</request>";
StringEntity entity = new StringEntity(xmlData, "UTF-8");
httpPost.setEntity(entity);
try (CloseableHttpResponse response = httpClient.execute(httpPost)) {
HttpEntity responseEntity = response.getEntity();
if (responseEntity != null) {
String responseString = EntityUtils.toString(responseEntity, "UTF-8");
System.out.println("Response: " + responseString);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
通过以上步骤和示例代码,你可以成功使用 Apache HttpClient 发送 XML POST 请求。
