type Body struct {
// FieldPath is a path to a proto field which the request body is mapped to.
// The request body is mapped to the request type itself if FieldPath is empty.
FieldPath FieldPath
}
Body describes a http requtest body to be sent to the method.

// File is the file where the enum is defined
File *File
// Outers is a list of outer messages if this enum is a nested type.
Outers []string
*descriptor.EnumDescriptorProto
Index int
}

type Field ¶
type Field struct {
// Message is the message type which this field belongs to.
Message *Message
// FieldMessage is the message type of the field.
FieldMessage *Message
*descriptor.FieldDescriptorProto
}
Field wraps descriptor.FieldDescriptorProto for richer features.
type FieldPath ¶
type FieldPath []FieldPathComponent
FieldPath is a path to a field from a request message.
func (FieldPath) AssignableExpr ¶ added in v1.4.0
AssignableExpr is an assignable expression in Go to be used to assign a value to the target field. It starts with "msgExpr", which is the go expression of the method request object.
func (FieldPath) IsNestedProto3 ¶
IsNestedProto3 indicates whether the FieldPath is a nested Proto3 path.
type FieldPathComponent ¶
type FieldPathComponent struct {
// Name is a name of the proto field which this component corresponds to.
// TODO(yugui) is this necessary?
Name string
// Target is the proto field which this component corresponds to.
Target *Field
}
FieldPathComponent is a path component in FieldPath
func (FieldPathComponent) AssignableExpr ¶ added in v1.4.0
func (c FieldPathComponent) AssignableExpr() string
AssignableExpr returns an assignable expression in go for this field.
func (FieldPathComponent) ValueExpr ¶ added in v1.4.0
func (c FieldPathComponent) ValueExpr() string
ValueExpr returns an expression in go for this field.
type File ¶
type File struct {
*descriptor.FileDescriptorProto
// GoPkg is the go package of the go file generated from this file..
GoPkg GoPackage
// Messages is the list of messages defined in this file.
Messages []*Message
// Enums is the list of enums defined in this file.
Enums []*Enum
// Services is the list of services defined in this file.
Services []*Service
}
File wraps descriptor.FileDescriptorProto for richer features.
type GoPackage ¶
type GoPackage struct {
// Path is the package path to the package.
Path string
// Name is the package name of the package
Name string
// Alias is an alias of the package unique within the current invokation of grpc-gateway generator.
Alias string
}
GoPackage represents a golang package
type GrpcAPIService ¶ added in v1.4.0
type GrpcAPIService struct {
// Http Rule. Named Http in the actual proto. Changed to suppress linter warning.
HTTP *annotations.Http `protobuf:"bytes,9,opt,name=http" json:"http,omitempty"`
}
GrpcAPIService represents a stripped down version of google.api.Service . Compare to https://github.com/googleapis/googleapis/blob/master/google/api/service.proto The original imports 23 other protobuf files we are not interested in. If a significant subset (>50%) of these start being reproduced in this file we should swap to using the full generated version instead.
For the purposes of the gateway generator we only consider a small subset of all available features google supports in their service descriptions. Thanks to backwards compatibility guarantees by protobuf it is safe for us to remove the other fields. We also only implement the absolute minimum of protobuf generator boilerplate to use our simplified version. These should be pretty stable too.
func (*GrpcAPIService) ProtoMessage ¶ added in v1.4.0
func (*GrpcAPIService) ProtoMessage()
ProtoMessage returns an empty GrpcAPIService element
func (*GrpcAPIService) Reset ¶ added in v1.4.0
func (m *GrpcAPIService) Reset()
Reset resets the GrpcAPIService
func (*GrpcAPIService) String ¶ added in v1.4.0
func (m *GrpcAPIService) String() string
String returns the string representation of the GrpcAPIService
type Message ¶
type Message struct {
// File is the file where the message is defined
File *File
// Outers is a list of outer messages if this message is a nested type.
Outers []string
*descriptor.DescriptorProto
Fields []*Field
// Index is proto path index of this message in File.
Index int
}
Message describes a protocol buffer message types
type Method ¶
type Method struct {
// Service is the service which this method belongs to.
Service *Service
*descriptor.MethodDescriptorProto
// RequestType is the message type of requests to this method.
RequestType *Message
// ResponseType is the message type of responses from this method.
ResponseType *Message
Bindings []*Binding
}
Method wraps descriptor.MethodDescriptorProto for richer features.
type Parameter ¶
type Parameter struct {
// FieldPath is a path to a proto field which this parameter is mapped to.
FieldPath
// Target is the proto field which this parameter is mapped to.
Target *Field
// Method is the method which this parameter is used for.
Method *Method
}
Parameter is a parameter provided in http requests
func (Parameter) ConvertFuncExpr ¶
ConvertFuncExpr returns a go expression of a converter function. The converter function converts a string into a value for the parameter.
type Registry ¶
type Registry struct {
// contains filtered or unexported fields
}
Registry is a registry of information extracted from plugin.CodeGeneratorRequest.
func (*Registry) AddExternalHTTPRule ¶ added in v1.4.0
func (r *Registry) AddExternalHTTPRule(qualifiedMethodName string, rule *annotations.HttpRule)
AddExternalHTTPRule adds an external http rule for the given fully qualified service method name
func (*Registry) GetAllFQENs ¶

func (*Registry) GetAllFQMNs ¶
GetAllFQMNs returns a list of all FQMNs
func (*Registry) Load ¶
func (r *Registry) Load(req *plugin.CodeGeneratorRequest) error
Load loads definitions of services, methods, messages, enumerations and fields from "req".
func (*Registry) LoadGrpcAPIServiceFromYAML ¶ added in v1.4.0
LoadGrpcAPIServiceFromYAML loads a gRPC API Configuration from the given YAML file and registers the HttpRule descriptions contained in it as externalHTTPRules in the given registry. This must be done before loading the proto file.
You can learn more about gRPC API Service descriptions from google's documentation at https://cloud.google.com/endpoints/docs/grpc/grpc-service-config
Note that for the purposes of the gateway generator we only consider a subset of all available features google supports in their service descriptions.
func (*Registry) LookupEnum ¶
LookupEnum looks up a enum type by "name". It tries to resolve "name" from "location" if "name" is a relative enum name.
func (*Registry) LookupExternalHTTPRules ¶ added in v1.4.0
func (r *Registry) LookupExternalHTTPRules(qualifiedMethodName string) []*annotations.HttpRule
LookupExternalHTTPRules looks up external http rules by fully qualified service method name
func (*Registry) LookupFile ¶
LookupFile looks up a file by name.
func (*Registry) LookupMsg ¶
LookupMsg looks up a message type by "name". It tries to resolve "name" from "location" if "name" is a relative message name.
func (*Registry) ReserveGoPackageAlias ¶
ReserveGoPackageAlias reserves the unique alias of go package. If succeeded, the alias will be never used for other packages in generated go files. If failed, the alias is already taken by another package, so you need to use another alias for the package in your go files.
func (*Registry) SetAllowDeleteBody ¶ added in v1.2.0
SetAllowDeleteBody controls whether http delete methods may have a body or fail loading if encountered.
func (*Registry) SetImportPath ¶ added in v1.3.1
SetImportPath registers the importPath which is used as the package if no input files declare go_package. If it contains slashes, everything up to the rightmost slash is ignored.
type Service ¶
type Service struct {
// File is the file where this service is defined.
File *File
*descriptor.ServiceDescriptorProto
// Methods is the list of methods defined in this service.
Methods []*Method
}
Service wraps descriptor.ServiceDescriptorProto for richer features.
