Assume I had created two REST Resources in webMethods, one is via HTTP Post method, another one is by HTTP Get method.
How do I test them by commons-httpclient?
How-to
Add two dependencies in your pom.xml
<dependency> <groupId>commons-httpclient</groupId> <artifactId>commons-httpclient</artifactId> <version>3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.5</version> </dependency>
Here has sample code to demonstrate how to send HTTP Post method and HTTP Get method using commons-httpclient:
package albert.practice.httpClient; import java.io.IOException; import org.apache.commons.httpclient.Credentials; import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.HttpException; import org.apache.commons.httpclient.HttpStatus; import org.apache.commons.httpclient.UsernamePasswordCredentials; import org.apache.commons.httpclient.auth.AuthScope; import org.apache.commons.httpclient.methods.GetMethod; import org.apache.commons.httpclient.methods.PostMethod; import org.apache.commons.io.IOUtils; import com.google.common.base.Charsets; public class HttpClientExample { private String post_uri = "http://10.12.14.28:5555/rest/test.restful.RestTest2"; private String get_uri = "http://10.12.14.28:5555/rest/test.restful.RestTest3"; private String inputJson = "{\"ip\":\"10.10.12.66\",\"state\": \"OFFLINE\"}"; /** * Implements the HTTP POST method. * * @return response code * @throws HttpException * @throws IOException */ public int sendPost() throws HttpException, IOException { AuthScope authScope = getAuthScope(); Credentials credentials = getCredentials(); HttpClient client = new HttpClient(); client.getState().setCredentials(authScope, credentials); PostMethod postMethod = new PostMethod(post_uri); postMethod.setDoAuthentication(true); postMethod.setParameter("data", inputJson); return client.executeMethod(postMethod); } /** * Implements the HTTP GET method. * * @return the response string of the HTTP method * @throws HttpException * @throws IOException */ public String sendGet() throws HttpException, IOException { String responseString = ""; AuthScope authScope = getAuthScope(); Credentials credentials = getCredentials(); HttpClient client = new HttpClient(); client.getState().setCredentials(authScope, credentials); GetMethod getMethod = new GetMethod(get_uri + "?input=albert"); getMethod.setDoAuthentication(true); int statusCode = client.executeMethod(getMethod); if (HttpStatus.SC_OK == statusCode) { responseString = IOUtils.toString(getMethod.getResponseBodyAsStream(), Charsets.UTF_8); } return responseString; } /** * Set authentication scope. * * @return authentication scope */ private AuthScope getAuthScope() { String ip = "10.12.14.28"; int port = 5555; String realm = AuthScope.ANY_REALM; AuthScope authScope = new AuthScope(ip, port, realm); return authScope; } /** * Set the authentication credentials for the given scope. * * @return credentials */ private Credentials getCredentials() { String username = "cctv"; String password = "cctv"; Credentials credentials = new UsernamePasswordCredentials(username, password); return credentials; } }
Here has the test code:
package albert.practice.httpClient; import static org.junit.Assert.assertEquals; import static org.junit.Assert.assertNotNull; import java.io.IOException; import org.apache.commons.httpclient.HttpException; import org.apache.commons.httpclient.HttpStatus; import org.junit.Before; import org.junit.Test; public class HttpClientExampleTest { private HttpClientExample httpClientExample; @Before public void setup() { httpClientExample = new HttpClientExample(); } @Test public void testSendPost() throws HttpException, IOException { int statusCode = httpClientExample.sendPost(); assertEquals(HttpStatus.SC_OK, statusCode); } @Test public void testSendGet() throws HttpException, IOException { String responseString = httpClientExample.sendGet(); System.out.println("responseString = " + responseString); assertNotNull(responseString); } }
