Sending credentials (user/pass) with RestTemplates - doesn't work for me ?

[evgenyg]

Hello,

Here's my REST Dao definition and custom request factory providing HttpClient with credentials:

<bean name="artifactoryDAO" class="com.clearforest.wd40.governor.dao.ArtifactoryDAO">
    <constructor-arg name  = "rest">
        <bean class="org.springframework.web.client.RestTemplate">
            <property name  = "requestFactory">
                <bean class = "com.clearforest.wd40.governor.dao.ArtifactoryCommonsClientHttpRequestFactory">
                    <constructor-arg name  = "user"
                                     value = "..."/>
                    <constructor-arg name  = "password"
                                     value = "..."/>
                </bean>
            </property>
        </bean>
    </constructor-arg>
</bean>


public class ArtifactoryCommonsClientHttpRequestFactory extends CommonsClientHttpRequestFactory
{
    private final String user;
    private       String user () { return user; }

    private final String password;
    private       String password () { return password; }


    public ArtifactoryCommonsClientHttpRequestFactory ( String user, String password )
    {
        this.user     = user;
        this.password = password;
    }


    @Override
    public HttpClient getHttpClient ()
    {
        HttpClient client = super.getHttpClient();

        if ( user() != null )
        {
            client.getState().setCredentials( AuthScope.ANY, new UsernamePasswordCredentials( user(), password()));
        }
        
        return client;
    }
}

For some reason, when I access REST resource with this RestTemplate as rest().getForObject() I always get 406 - http://goo.gl/xwic

But this code works Ok:

String     request    = "...";
GetMethod  getMethod  = new GetMethod( request );
HttpClient httpClient = new HttpClient();

httpClient.getState().setCredentials( AuthScope.ANY,
                                      new org.apache.commons.httpclient.UsernamePasswordCredentials( "...", "..." ));
httpClient.executeMethod( getMethod );
String s = getMethod.getResponseBodyAsString();

It seems as if using RestTemplate doesn't send the credentials. I've debugged the RestTemplate instance and made sure it contains HttpClient with a state holding the right credentials. I'm yet to sniff the HTTP traffic to see what exactly is sent over the network.


My question is: is there anybody else experiencing similar issues when sending credentials with RestTemplate? I guess I'll have more information after sniffing but thought I'll ask it here as well.

Thank you!

The problem was caused by RestTemplate sending "Accept: text/plain, */*\r\n" header.
Changing it to "Accept: */*" solved the issue

And, btw, the difference between using RestTemplate and plain HttpClient was that HttpClient didn't send Accept header. Thats what caused the request to go through.

Have you found a way to use HttpClient 4.x to do this? I've looked at the tickets for upgrading to 4.x, and it seems they are languishing away after a year.

I think yes, it was quite a while ago. I'll be able to get back with more details on Sunday, when I'll be in the office.

I see what I did is to set the "Authorization" header before sending a request:

org.springframework.http.HttpHeaders headers = new HttpHeaders();
headers.set( "Authorization", "..." );

T    response = rest( /* returns RestTemplate instance */).exchange( url, method, new HttpEntity<String>( headers ), responseType, args ).getBody();

Used a basic authentication so "..." above is:

echo -n server:password | base64
