这是我从网上复制的代码
/**
* A simple example that uses HttpClient to perform a GET using Basic

*/
public class BasicAuthenticationExample {
/**
* Constructor for BasicAuthenticatonExample.
*/
public BasicAuthenticationExample() {
super();
}
public static void main(String[] args) throws Exception {
HttpClient client = new HttpClient();
client.getState().setCredentials(
new AuthScope("login.website.com", 443),
new UsernamePasswordCredentials("login id", "password")
);
GetMethod get = new GetMethod(
"https://url to the file");
get.setDoAuthentication( true );
try {
// execute the GET
int status = client.executeMethod( get );
// print the status and response
System.out.println(status + "\n" +
get.getResponseBodyAsString());
} finally {
// release any connection resources used by the method
get.releaseConnection();
}
}
}
现在因为这条线
int status = client.executeMethod( get );
我收到以下错误

现在这个错误的原因当然是我的服务器发送的证书不在我的受信任证书列表中。我的问题是如何将证书放入受信任的列表中。
