Functions

func BindQueryParameter

func BindQueryParameter(style string, explode bool, required bool, paramName string,
	queryParams url.Values, dest interface{}) error

BindQueryParameter works much like BindStyledParameter, however it takes a query argument input array from the url package, since query arguments come through a different path than the styled arguments. They're also exceptionally fussy. For example, consider the exploded and unexploded form parameter examples: (exploded) /users?role=admin&firstName=Alex (unexploded) /users?id=role,admin,firstName,Alex

In the first case, we can pull the "id" parameter off the context, and unmarshal via json as an intermediate. Easy. In the second case, we don't have the id QueryParam present, but must find "role", and "firstName". what if there is another parameter similar to "ID" named "role"? We can't tell them apart. This code tries to fail, but the moral of the story is that you shouldn't pass objects via form styled query arguments, just use the Content parameter form.

func BindStringSliceToObjectSlice

func BindStringSliceToObjectSlice(src []string, field reflect.Value) error

func BindStringToObject

func BindStringToObject(src string, dst interface{}) error

This function takes a string, and attempts to assign it to the destination interface via whatever type conversion is necessary. We have to do this via reflection instead of a much simpler type switch so that we can handle type aliases. This function was the easy way out, the better way, since we know the destination type each place that we use this, is to generate code to read each specific type.

func BindStyledParameter

func BindStyledParameter(style string, explode bool, paramName string,
	value string, dest interface{}) error

This function binds a parameter as described in the Path Parameters section here to a Go object: https://swagger.io/docs/specification/serialization/ It is a backward compatible function to clients generated with codegen up to version v1.5.5. v1.5.6+ calls the function below.

func BindStyledParameterWithLocation

func BindStyledParameterWithLocation(style string, explode bool, paramName string,
	paramLocation ParamLocation, value string, dest interface{}) error

This function binds a parameter as described in the Path Parameters section here to a Go object: https://swagger.io/docs/specification/serialization/

func MarshalDeepObject

func MarshalDeepObject(i interface{}, paramName string) (string, error)

func StyleParam

func StyleParam(style string, explode bool, paramName string, value interface{}) (string, error)

This function is used by older generated code, and must remain compatible with that code. It is not to be used in new templates. Please see the function below, which can specialize its output based on the location of the parameter.

func StyleParamWithLocation

func StyleParamWithLocation(style string, explode bool, paramName string, paramLocation ParamLocation, value interface{}) (string, error)

Given an input value, such as a primitive type, array or object, turn it into a parameter based on style/explode definition, performing whatever escaping is necessary based on parameter location

func UnmarshalDeepObject

func UnmarshalDeepObject(dst interface{}, paramName string, params url.Values) error

func ValidateInput

func ValidateInput(params interface{}) error

Types

type Binder

type Binder interface {
	Bind(src string) error
}

Binder is the interface implemented by types that can be bound to a query string or a parameter string The input can be assumed to be a valid string. If you define a Bind method you are responsible for all data being completely bound to the type.

By convention, to approximate the behavior of Bind functions themselves, Binder implements Bind("") as a no-op.

type ParamLocation

type ParamLocation int

Parameter escaping works differently based on where a header is found

const (
	ParamLocationUndefined ParamLocation = iota
	ParamLocationQuery
	ParamLocationPath
	ParamLocationHeader
	ParamLocationCookie
)
