Question

我正在尝试访问RabbitMQ休息，但我有401个未经授权的错误。我想访问队列信息并获取消息号。

我发现这是一个解决方案

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpHost targetHost = new HttpHost("xx.xx.xx.xx", 15672, "http");

HttpPut request = new HttpPut(
    "/api/queues/%2F/queue-name");

httpClient.getCredentialsProvider().setCredentials(
    new AuthScope(targetHost.getHostName(), targetHost.getPort()),
    new UsernamePasswordCredentials("guest", "guest"));

AuthCache authCache = new BasicAuthCache();
BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);
BasicHttpContext localcontext = new BasicHttpContext();
localcontext.setAttribute(ClientContext.AUTH_CACHE, authCache);

request.addHeader("Content-Type", "application/json");

StringEntity input = new StringEntity(
    "{\"vhost\":\"/\",\"durable\":\"false\",\"auto_delete\":\"false\",\"arguments\":{}}");

request.setEntity(input);

HttpResponse response = httpClient.execute(targetHost, request, localcontext);

但它不起作用。我看到DefaultHttpClient类被折旧，所以我尝试了类似这样的东西

HttpHost targetHost = new HttpHost("xx.xx.xx.xx", 15672, "http");
    HttpPut request = new HttpPut("/api/whoami");

    CloseableHttpClient httpClient = HttpClientBuilder.create().build();
    CredentialsProvider credentialProvider = new BasicCredentialsProvider();
    credentialProvider.setCredentials(
        new AuthScope(targetHost.getHostName(), targetHost.getPort()),
        new UsernamePasswordCredentials("guest","guest")
    );

    AuthCache authCache = new BasicAuthCache();
    BasicScheme basicAuth = new BasicScheme();
    authCache.put(targetHost, basicAuth);
    HttpClientContext context = HttpClientContext.create();
    context.setCredentialsProvider(credentialProvider);
    context.setAuthCache(authCache);

    request.addHeader("Content-Type", "application/json");

    HttpResponse response = httpClient.execute(targetHost, request, context);

然后访问REST思想WebTarget，类似这样的

WebTarget queueREST = RESTClientManager.getClient().target("xx.xx.xx.xx:15672/api/queues/%2F/queue-name");

但我仍然得到错误401未经授权。有任何建议如何解决这个问题？

Answer 1

“guest”用户只能通过localhost连接。允许使用访客更改Cannot GET '/'进行远程连接并添加rabbitmq.config

[来源：https://www.rabbitmq.com/access-control.html]

在我的情况下，我用以下方法解决：

[{rabbit, [{loopback_users, []}]}].

您可以使用更完整的my rabbitmq-management-java-client 库。

例如，用于验证和列出队列的代码段：

RabbitManagementApi api = RabbitManagementApi.newInstance("http://localhost:15672/" , "user" , "password");
List<Queue> queues = api.listQueues("vhost");

RabbitMQ HTTP API请求401未经授权
