gRPC Transcoding
gRPC Transcoding is a feature for mapping between a gRPC method and one or
more HTTP REST endpoints. It allows developers to build a single API service
that supports both gRPC APIs and REST APIs. Many systems, including Google
APIs,
Cloud Endpoints, gRPC
Gateway,
and Envoy proxy support this feature
and use it for large scale production services.
HttpRule
defines the schema of the gRPC/REST mapping. The mapping specifies
how different portions of the gRPC request message are mapped to the URL
path, URL query parameters, and HTTP request body. It also controls how the
gRPC response message is mapped to the HTTP response body. HttpRule
is
typically specified as an google.api.http
annotation on the gRPC method.
Each mapping specifies a URL path template and an HTTP method. The path
template may refer to one or more fields in the gRPC request message, as long
as each field is a non-repeated field with a primitive (non-message) type.
The path template controls how fields of the request message are mapped to
the URL path.
Example:
service Messaging {
rpc GetMessage(GetMessageRequest) returns (Message) {
option (google.api.http) = {
get: "/v1/{name=messages/*}"
};
}
}
message GetMessageRequest {
string name = 1; // Mapped to URL path.
}
message Message {
string text = 1; // The resource content.
}
This enables an HTTP REST to gRPC mapping as below:
HTTP | gRPC |
---|---|
GET /v1/messages/123456 | GetMessage(name: "messages/123456") |
Any fields in the request message which are not bound by the path template
automatically become HTTP query parameters if there is no HTTP request body.
For example:
service Messaging {
rpc GetMessage(GetMessageRequest) returns (Message) {
option (google.api.http) = {
get:"/v1/messages/{message_id}"
};
}
}
message GetMessageRequest {
message SubMessage {
string subfield = 1;
}
string message_id = 1; // Mapped to URL path.
int64 revision = 2; // Mapped to URL query parameter revision
.
SubMessage sub = 3; // Mapped to URL query parameter sub.subfield
.
}
This enables a HTTP JSON to RPC mapping as below:
HTTP | gRPC |
---|---|
GET /v1/messages/123456?revision=2&sub.subfield=foo |
GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
"foo"))
Note that fields which are mapped to URL query parameters must have a
primitive type or a repeated primitive type or a non-repeated message type.
In the case of a repeated type, the parameter can be repeated in the URL
as ...?param=A¶m=B
. In the case of a message type, each field of the
message is mapped to a separate parameter, such as
...?foo.a=A&foo.b=B&foo.c=C
.
For HTTP methods that allow a request body, the body
field
specifies the mapping. Consider a REST update method on the
message resource collection:
service Messaging {
rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
option (google.api.http) = {
patch: "/v1/messages/{message_id}"
body: "message"
};
}
}
message UpdateMessageRequest {
string message_id = 1; // mapped to the URL
Message message = 2; // mapped to the body
}
The following HTTP JSON to RPC mapping is enabled, where the
representation of the JSON in the request body is determined by
protos JSON encoding:
HTTP | gRPC |
---|---|
PATCH /v1/messages/123456 { "text": "Hi!" } | UpdateMessage(message_id: |
"123456" message { text: "Hi!" })
The special name can be used in the body mapping to define that
every field not bound by the path template should be mapped to the
request body. This enables the following alternative definition of
the update method:
service Messaging {
rpc UpdateMessage(Message) returns (Message) {
option (google.api.http) = {
patch: "/v1/messages/{message_id}"
body: ""
};
}
}
message Message {
string message_id = 1;
string text = 2;
}
The following HTTP JSON to RPC mapping is enabled:
HTTP | gRPC |
---|---|
PATCH /v1/messages/123456 { "text": "Hi!" } | UpdateMessage(message_id: |
"123456" text: "Hi!")
Note that when using in the body mapping, it is not possible to
have HTTP parameters, as all fields not bound by the path end in
the body. This makes this option more rarely used in practice when
defining REST APIs. The common usage of
is in custom methods
which don't use the URL at all for transferring data.
It is possible to define multiple HTTP methods for one RPC by using
the
additional_bindings
option. Example:
service Messaging {
rpc GetMessage(GetMessageRequest) returns (Message) {
option (google.api.http) = {
get: "/v1/messages/{message_id}"
additional_bindings {
get: "/v1/users/{user_id}/messages/{message_id}"
}
};
}
}
message GetMessageRequest {
string message_id = 1;
string user_id = 2;
}
This enables the following two alternative HTTP JSON to RPC mappings:
HTTP | gRPC |
---|---|
GET /v1/messages/123456 | GetMessage(message_id: "123456") |
GET /v1/users/me/messages/123456 | GetMessage(user_id: "me" message_id: |
"123456")
Rules for HTTP mapping
- Leaf request fields (recursive expansion nested messages in the request
message) are classified into three categories:
- Fields referred by the path template. They are passed via the URL path.
- Fields referred by the HttpRule.body. They are passed via the HTTP request body.
- All other fields are passed via the URL query parameters, and the parameter name is the field path in the request message. A repeated field can be represented as multiple query parameters under the same name.
- If HttpRule.body is "*", there is no URL query parameter, all fields are passed via URL path and HTTP request body.
- If HttpRule.body is omitted, there is no HTTP request body, all
fields are passed via URL path and URL query parameters.
### Path template syntax
Template = "/" Segments [ Verb ] ;
Segments = Segment { "/" Segment } ;
Segment = "" | "" | LITERAL | Variable ;
Variable = "{" FieldPath [ "=" Segments ] "}" ;
FieldPath = IDENT { "." IDENT } ;
Verb = ":" LITERAL ;
The syntax
matches a single URL path segment. The syntax
matches zero or more URL path segments, which must be the last part of the URL path except the
Verb
. The syntaxVariable
matches part of the URL path as specified by its template. A variable template must not contain other variables. If a variable matches a single path segment, its template may be omitted, e.g.{var}
is equivalent to{var=}
. The syntaxLITERAL
matches literal text in the URL path. If theLITERAL
contains any reserved character, such characters should be percent-encoded before the matching. If a variable contains exactly one path segment, such as"{var}"
or"{var=}"
, when such a variable is expanded into a URL path on the client side, all characters except[-_.~0-9a-zA-Z]
are percent-encoded. The server side does the reverse decoding. Such variables show up in the Discovery Document as{var}
. If a variable contains multiple path segments, such as"{var=foo/*}"
or"{var=}"
, when such a variable is expanded into a URL path on the client side, all characters except[-_.~/0-9a-zA-Z]
are percent-encoded. The server side does the reverse decoding, except "%2F" and "%2f" are left unchanged. Such variables show up in the Discovery Document as{+var}
. ## Using gRPC API Service Configuration gRPC API Service Configuration (service config) is a configuration language for configuring a gRPC service to become a user-facing product. The service config is simply the YAML representation of thegoogle.api.Service
proto message. As an alternative to annotating your proto file, you can configure gRPC transcoding in your service config YAML files. You do this by specifying aHttpRule
that maps the gRPC method to a REST endpoint, achieving the same effect as the proto annotation. This can be particularly useful if you have a proto that is reused in multiple services. Note that any transcoding specified in the service config will override any matching transcoding configuration in the proto. Example: http: rules: # Selects a gRPC method and applies HttpRule to it.- selector: example.v1.Messaging.GetMessage
get: /v1/messages/{message_id}/{sub.subfield}
## Special notes
When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
proto to JSON conversion must follow the proto3
specification.
While the single segment variable follows the semantics of
RFC 6570 Section 3.2.2 Simple String
Expansion, the multi segment variable does not follow RFC 6570 Section
3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
does not expand special characters like
?
and#
, which would lead to invalid URLs. As the result, gRPC Transcoding uses a custom encoding for multi segment variables. The path variables must not refer to any repeated or mapped field, because client libraries are not capable of handling such variable expansion. The path variables must not capture the leading "/" character. The reason is that the most common use case "{var}" does not capture the leading "/" character. For consistency, all path variables must share the same behavior. Repeated message fields must not be mapped to URL query parameters, because no client library can support such complicated mapping. If an API needs to use a JSON array for request or response body, it can map the request or response body to a repeated field. However, some gRPC Transcoding implementations may not support this feature.

get: /v1/messages/{message_id}/{sub.subfield}
