Functions

func DeclarativeFriendlyResource added in v1.6.0 

func DeclarativeFriendlyResource(d desc.Descriptor) *desc.MessageDescriptor

DeclarativeFriendlyResource returns the declarative-friendly resource associated with this descriptor.

For messages: If the message is annotated with google.api.resource and style: DECLARATIVE_FRIENDLY is set, that message is returned. If the message is a standard method request message for a resource with google.api.resource and style:DECLARATIVE_FRIENDLY set, then the resource is returned.

For methods: If the output message is a declarative-friendly resource, it is returned. If the method begins with "List" and the first repeated field is a declarative-friendly resource, the resource is returned. If the method begins with "Delete", the return type is Empty, and an appropriate resource message is found and is declarative-friendly, that resource is returned. If the method is a custom method where a matching resource is found (by subset checks on the name) and is declarative-friendly, the resource is returned.

If there is no declarative-friendly resource, it returns nil.

Types

type HTTPRule 

type HTTPRule struct {
	// The HTTP method. Guaranteed to be in all caps.
	// This is set to "CUSTOM" if the Custom property is set.
	Method string

	// The HTTP URI (the value corresponding to the selected HTTP method).
	URI string

	// The `body` value forwarded from the generated proto's HttpRule.
	Body string

	// The `response_body` value forwarded from the generated proto's HttpRule.
	ResponseBody string
}

HTTPRule defines a parsed, easier-to-query equivalent to `apb.HttpRule`.

func GetHTTPRules 

func GetHTTPRules(m *desc.MethodDescriptor) []*HTTPRule

GetHTTPRules returns a slice of HTTP rules for a given method descriptor.

Note: This returns a slice -- it takes the google.api.http annotation, and then flattens the values in `additional_bindings`. This allows rule authors to simply range over all of the HTTP rules, since the common case is to want to apply the checks to all of them.

func (*HTTPRule) GetPlainURI 

func (h *HTTPRule) GetPlainURI() string

GetPlainURI returns the URI with variable segment information removed.

func (*HTTPRule) GetVariables 

func (h *HTTPRule) GetVariables() map[string]string

GetVariables returns the variable segments in a URI as a map.

For a given variable, the key is the variable's field path. The value is the variable's template, which will match segment(s) of the URL.

For more details on the path template syntax, see https://github.com/googleapis/googleapis/blob/6e1a5a066659794f26091674e3668229e7750052/google/api/http.proto#L224.
