Phusion 乘客在连接 MongoDB 集群时"Error: missing delimiting slash between hosts and options"错误

Question

我已经部署了自己的mongodb群集。我有一个运行的流星应用程序，该应用程序正在nginx顶部运行。在更新nginx配置文件中的连接字符串之后，我会遇到以下错误：

/<app_directory>/bundle/programs/server/node_modules/fibers/future.js:280
                                                throw(ex);
                                                ^
Error: missing delimiting slash between hosts and options

当连接字符串以下格式之前，该应用程序运行良好：

passenger_env_var MONGO_URL mongodb://db_user:db_password@host_name:port_no/db_name;

，但是当我尝试通过以下方式更新连接字符串时，它开始显示错误：

passenger_env_var MONGO_URL mongodb://db_user:'password_with_special_character'@host1_name:port_no,host2_name:port_no/db_name?replicaSet=replica_set_name;

连接字符串或任何其他问题有什么问题？

Answer 1

这不是乘客的问题，它在配置时只会在字符串上传递。通常，您会用：

的引号将整个字符串包围

passenger_env_var MONGO_URL 'mongodb://db_user:password_with_special_character@host1_name:port_no,host2_name:port_no/db_name?replicaSet=replica_set_name;'

问题是Mongo客户端需要了解字符串，这意味着您需要使用它支持的逃逸机制，例如URL编码。例如，如果密码包含@，则可以用%40进行编码：

# password = p@ssword, @ = url encoded as %40
passenger_env_var MONGO_URL 'mongodb://username:p%40ssword@host:port/dbname';

您可以在此处查看其他特殊字符的默认URL编码。
