Question

我有连接代码：

$.ajax({
        url: /*url to server file(.php/.aspx) pass value to database*/,
        type: 'POST',
        cache: false,
        data: 'textboxvalue=' + /*value from your textbox. ex: $('#txtInput').val()*/,
        success: function(res) {
            /*If connect success and server work successfully, what you want to do here*/
            
        },
        error: function() {
            alert("Connection error");
            return;
        }
    });

但是我收到了错误：

ConnectionFactory factory = new ConnectionFactory();
factory.setUri(System.getenv("CLOUDAMQP_URL"));

我的兔子日志显示连接拒绝

如何使用setUri连接到默认vhost（/）？询问last time这个问题，提问者的解决方案是不使用setUri。什么是uri方式？

令人讨厌的是，同样的URI与pika一起工作;这两个实现（python和java）如何解析URI有什么不同？

编辑：我使用的网址是

=ERROR REPORT==== 21-Jul-2015::23:16:27 ===
closing AMQP connection <0.9858.0> (127.0.0.1:38856 -> 127.0.0.1:5672):
{handshake_error,opening,0,
                 {amqp_error,access_refused,
                             "access to vhost '' refused for user 'guest'",
                             'connection.open'}}

Answer 1

看起来这与在the source中解析URI的方式不一致。特别是，URI在/ s上分割，然后是URL解码;这意味着我的URI（amqp://guest:guest@localhost:5672/）返回vhost的空字符串（而不是我使用

的默认/ like python does).

factory.setUri(System.getenv("CLOUDAMQP_URL"));
factory.setVirtualHost("/");

覆盖推断的错误值，但这是不好的解决方案。另一个有效的解决方案是更改URL：

CLOUDAMQP_URL=amqp://guest:guest@localhost:5672/%2F

注意URLencoded / via ％2F 。我将在库中打开一个问题/ PR，因为python解决方案似乎更直观。

编辑：我与图书馆维护人员进行了交谈。他们指出，他们是权威的实施，而且pika正在the spec之外做一些事情（见附录A）。令人遗憾的是，库存兔实现（使用＆＃34; /＆＃34;的vhost）与库存java rabbit mq客户端对默认URI的解释不兼容，但事实如此。使用％2F修复。

使用rabbitmq中的factory.setUri（）连接到/ vhost
