mongodb - 连接 MongoDB 集群时 Phusion Passenger "Error: missing delimiting slash between hosts and options"错误

Question

我已经部署了自己的 MongoDB 集群。我有一个正在运行的 Meteor 应用程序，它在 Nginx 的顶部与 Phusion Passenger 一起运行。更新 Nginx 配置文件中的连接字符串后出现以下错误:

/<app_directory>/bundle/programs/server/node_modules/fibers/future.js:280
                                                throw(ex);
                                                ^

Error: missing delimiting slash between hosts and options

当连接字符串之前采用以下格式时，应用程序运行正常:

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来连接到 mu mongoDB 集群时，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;

是连接字符串有问题还是其他什么问题？

Answer 1

这不是 Passenger 的问题，它只是在您配置时传递字符串。通常您会用引号将整个字符串括起来，例如:

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;'

问题在于 Mongo 客户端需要理解字符串，这意味着您需要使用它支持的转义机制，例如 URL 编码。例如，如果密码包含 @，您可以使用 %40 对其进行 URL 编码:

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

可以看到其他特殊字符的默认URL编码here .
