mongo shell JavaScript等效于--sslCAFile

Question

I'm using JavaScript to connect to multiple databases at once from the mongo shell. However, one of my databases is on Digital Ocean instead of AWS so I have an SSL certificate on my EC2 server.

In general, I use something similar to this to connect and use multiple servers on one file:

var iptDb = connect("###.###.###.###:27017/dbname);
iptDb.auth("username", cat("pw"));

In order to connect to my Digital Ocean database, I know that I need to add ?ssl=true , like below, but I don't know where I put the certificate information.

var iptDb = connect("###.###.###.###:27017/dbname?ssl=true");
iptDb.auth("username", cat("pw"));

mongo uses --sslCAFile in the shell to give the certificate path.

What would be the equivalent if I want to write it in my JavaScript file?

The mongo shell isn't intended to be a full driver replacement; some options (like --sslCAFile ) can only be provided as command line parameters. As at MongoDB 3.2 there are other limitations of mongo shell scripts such as few I/O options (no input methods and limited output methods).

If your requirements are relatively straightforward and you don't want to install a driver, you could perhaps write a shell script (bash/zsh/...) to run multiple invocations of mongod with the expected connection parameters.

For any significant scripting I would recommend using one of the officially supported drivers which will include full support for SSL options. For example, see the Node.js driver SSL connection tutorial .
