我使用 Apache HttpComponents 访问 Web 服务，但不知道如何在请求中设置用户/密码，这是我的代码：
URI url = new URI(query);
HttpGet httpget = new HttpGet(url);
DefaultHttpClient httpclient = new DefaultHttpClient();

httpclient.getCredentialsProvider().setCredentials(new AuthScope(HOST, AuthScope.ANY_PORT), defaultcreds);
HttpResponse response = httpclient.execute(httpget);

I think you are on the right track. Perhaps you should check your user credential as the http error responsecould probably means incorrect username/password or the user does not have the privilege to access the resources. I have the below code which I do basic http authentication and it is working fine.
我认为你在正确的轨道上。也许您应该检查您的用户凭据，因为 http错误响应可能意味着不正确的用户名/密码或用户没有访问资源的权限。我有以下代码，用于进行基本的 http 身份验证，并且工作正常。
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
public class Authentication
{
public static void main(String[] args)
{
DefaultHttpClient dhttpclient = new DefaultHttpClient();
String username = "abc";
String password = "def";
String host = "abc.example.com";
String uri = "http://abc.example.com/protected";
try
{
dhttpclient.getCredentialsProvider().setCredentials(new AuthScope(host, AuthScope.ANY_PORT), new UsernamePasswordCredentials(username, password));
HttpGet dhttpget = new HttpGet(uri);
System.out.println("executing request " + dhttpget.getRequestLine());
HttpResponse dresponse = dhttpclient.execute(dhttpget);
System.out.println(dresponse.getStatusLine() );
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
dhttpclient.getConnectionManager().shutdown();
}
}
}
