The following example shows a direct GET request using basic authentication:
import com.sap.httpclient.HttpClient; import com.sap.httpclient.HostConfiguration; import com.sap.httpclient.auth.UserPassCredentials; import com.sap.httpclient.auth.AuthScope; import com.sap.httpclient.http.methods.GET; /** * A simple example that uses HttpClient to perform * a direct GET request using Basic Authentication. */ public class SimpleExample4 { public static void main(String[] args) throws Exception { // creating the http client instance HttpClient client = new HttpClient(); // creating the host configuration HostConfiguration host = new HostConfiguration("www.verisign.com", 443); // setting the proxy to the host configuration host.setProxy("proxy", 8080); // setting the host configuration to the client client.setHostConfiguration(host); // creating the authentication scope for realm "realm" // on the host "www.verisign.com" AuthScope ourScope = new AuthScope("www.verisign.com", 443, "realm"); // creating the credentials UserPassCredentials userPass = new UserPassCredentials("username", "password"); // pass our scope and credentials to HttpClient client.getState().setCredentials(ourScope, userPass); // create a GET method that reads a file over HTTPS, we are assuming // that this file requires basic authentication using the // realm above. GET httpGet = new GET("https://www.verisign.com/products/index.html"); // Tell the GET method to automatically handle authentication. // The method will use any appropriate // credentials to handle basic authentication requests. // Setting this value to false will cause // any request for authentication to return with a status of 401. // It will then be up to the client to handle the authentication. httpGet.setDoAuthentication(true); try { // execute the http method int status = client.executeMethod(httpGet); // showing the response System.out.println("RESPONSE : "); System.out.println(httpGet.getResponseBodyAsString()); } finally { // we wont use the connection any more so we release it httpGet.releaseConnection(); } } }
