Functions

func BuildRequestBody

func BuildRequestBody(opts interface{}, parent string) (map[string]interface{}, error)

BuildRequestBody builds a map[string]interface from the given `struct`. If parent is not an empty string, the final map[string]interface returned will encapsulate the built one. For example:

disk := 1
createOpts := flavors.CreateOpts{
  ID:         "1",
  Name:       "m1.tiny",
  Disk:       &disk,
  RAM:        512,
  VCPUs:      1,
  RxTxFactor: 1.0,
}

body, err := BuildRequestBody(createOpts, "flavor")

The above example can be run as-is, however it is recommended to look at how BuildRequestBody is used within Gophercloud to more fully understand how it fits within the request process as a whole rather than use it directly as shown above.
