How do I access other services from a function?

Function Compute provides an environment in which you can access other services such as Object Storage Service (OSS) and Message Service (MNS), databases, self-built HTTP services, and Function Compute functions in the same way you access the services from an on-premises machine. You need to only package and upload the corresponding dependency libraries together with the function code to access the services from a function. For more information about how to package dependencies, see Install third-party dependencies for a function.
