java中httpclient实现digest验证的请求

1、首先介绍如何使用HttpClient发起GET和POST请求

GET 方式：
//先将参数放入List，再对参数进行URL编码

List<BasicNameValuePair> params = new LinkedList<BasicNameValuePair>();

params.add(new BasicNameValuePair("param1", "中国"));

params.add(new BasicNameValuePair("param2", "value2"));

 

//对参数编码

String param = URLEncodedUtils.format(params, "UTF-8");

 

//baseUrl           

String baseUrl = "

 

 

//将URL与参数拼接

HttpGet getMethod = new HttpGet(baseUrl + "?" + param);

             

HttpClient httpClient = new DefaultHttpClient();

 

try {

    HttpResponse response = httpClient.execute(getMet搜索hod); //发起GET请求

 

    Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码

    Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8"));//获取服务器响应内容

} catch (ClientProtocolException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

} catch (IOException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

} 


 

POST方式：
//和GET方式一样，先将参数放入List

params = new LinkedList<BasicNameValuePair>();

params.add(new BasicNameValuePair("param1", "Post方法"));

params.add(new BasicNameValuePair("param2", "第二个参数"));

             

try {

    HttpPost postMethod = new HttpPost(baseUrl);

    postMethod.setEntity(new UrlEncodedFormEntity(params, "utf-8")); //将参数填入POST Entity中

                 

    HttpResponse response = httpClient.execute(postMethod); //执行POST方法

    Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码

    Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8")); //获取响应内容

                 

} catch (UnsupportedEncodingException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

} catch (ClientProtocolException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

} catch (IOException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

}

2、httpclient的digest验证，需要tomcat服务器配置digest验证，具体配置参见先前博文。

[java] view plain copy print?

package test.util;
import java.net.URI;
import java.util.ArrayList;
import java.util.List;
import org.apache.commons.httpclient.auth.AuthPolicy;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.Credentials;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.impl.auth.DigestSchemeFactory;
import org.apache.http.impl.client.DefaultHttpClient;
/**
* @author Administrator
*
*/
public class HTTPDigestClient {
private URI serverURI = null;
String response = null;
private DefaultHttpClient httpClient = new DefaultHttpClient();
/**
* constructor
*/
public HTTPDigestClient(String userName, String passWord, String url) {
try {
serverURI = new URI(url);
Credentials creds = new UsernamePasswordCredentials(userName,
passWord);
httpClient.getCredentialsProvider().setCredentials(
new AuthScope(serverURI.getHost(), serverURI.getPort), (Credentials) creds);
httpClient.getParams().setParameter(
AuthPolicy.AUTH_SCHEME_PRIORITY, Collections.singleton(AuthPolicy.DIGEST));
httpClient.getAuthSchemes().register(AuthPolicy.DIGEST,
new DigestSchemeFactory());
} catch (Exception e) {
}
}
/**
* send request to server
*
* @param httpClient
* @param httpUriRequest
* @return response HttpResponse
*/
public HttpResponse send(HttpUriRequest httpUriRequest) {
HttpResponse response = null;
try {
if (null == httpClient) {
return response;
}
response = httpClient.execute(httpUriRequest);
} catch (Exception e) {
}
return response;
}
}

package test.util;

import java.net.URI;
import java.util.ArrayList;
import java.util.List;

import org.apache.commons.httpclient.auth.AuthPolicy;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.Credentials;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.impl.auth.DigestSchemeFactory;
import org.apache.http.impl.client.DefaultHttpClient;

/**
 * @author Administrator
 * 
 */
public class HTTPDigestClient {
	private URI serverURI = null;
	String response = null;
	private DefaultHttpClient httpClient = new DefaultHttpClient();

	/**
	 * constructor
	 */
	public HTTPDigestClient(String userName, String passWord, String url) {
		try {
			serverURI = new URI(url);
			Credentials creds = new UsernamePasswordCredentials(userName,
					passWord);

			httpClient.getCredentialsProvider().setCredentials(
					new AuthScope(serverURI.getHost(), serverURI.getPort), (Credentials) creds);

			httpClient.getParams().setParameter(
					AuthPolicy.AUTH_SCHEME_PRIORITY, Collections.singleton(AuthPolicy.DIGEST));
			httpClient.getAuthSchemes().register(AuthPolicy.DIGEST,
					new DigestSchemeFactory());

		} catch (Exception e) {
			
		}
	}

	/**
	 * send request to server
	 * 
	 * @param httpClient
	 * @param httpUriRequest
	 * @return response HttpResponse
	 */
	public HttpResponse send(HttpUriRequest httpUriRequest) {
		HttpResponse response = null;
		try {
			if (null == httpClient) {
				
				return response;
			}
			response = httpClient.execute(httpUriRequest);

		} catch (Exception e) {
			
		}
		return response;
	}

}

服务器端必须加入域

设置realm 为空或者当前域名测试成功

用户名密码用的是域账户

下面为basic验证方式，测试通过

[java] view plain copy print?

package test.util;
import java.net.URI;
import java.util.Collections;
import org.apache.commons.httpclient.auth.AuthPolicy;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.Credentials;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.impl.auth.BasicSchemeFactory;
import org.apache.http.impl.client.DefaultHttpClient;
/**
* @author Administrator
*
*/
public class HTTPBasicClient {
private URI serverURI = null;
String response = null;
private DefaultHttpClient httpClient = new DefaultHttpClient();
/**
* constructor
*
*/
public HTTPBasicClient(String userName, String passWord, String url) {
try {
serverURI = new URI(url);
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(
userName, passWord);
CredentialsProvider credsProvider = httpClient
.getCredentialsProvider();
credsProvider.setCredentials(new AuthScope(serverURI.getHost(),
serverURI.getPort()), (Credentials) creds);
httpClient.getParams().setParameter(
AuthPolicy.AUTH_SCHEME_PRIORITY,
Collections.singleton(AuthPolicy.BASIC));
httpClient.getAuthSchemes().register(AuthPolicy.BASIC,
new BasicSchemeFactory());
} catch (Exception e) {
}
}
/**
* send request to server
*
* @param httpClient
* @param httpUriRequest
* @return response HttpResponse
*/
public HttpResponse send(HttpUriRequest httpUriRequest) {
HttpResponse response = null;
try {
if (null == httpClient) {
return response;
}
response = httpClient.execute(httpUriRequest);
} catch (Exception e) {
}
return response;
}
}
