| // # 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](https://github.com/googleapis/googleapis), | ||
| // [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC | ||
| // Gateway](https://github.com/grpc-ecosystem/grpc-gateway), | ||
| // and [Envoy](https://github.com/envoyproxy/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 | ||
| // | ||
| // 1. 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][google.api.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. | ||
| // 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL | ||
| // query parameter, all fields | ||
| // are passed via URL path and HTTP request body. | ||
| // 3. If [HttpRule.body][google.api.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 syntax `Variable` 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 syntax `LITERAL` matches literal text in the URL path. If the `LITERAL` | ||
| // 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](https://developers.google.com/discovery/v1/reference/apis) 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](https://developers.google.com/discovery/v1/reference/apis) 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 the `google.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 a | ||
| // `HttpRule` 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](https://developers.google.com/protocol-buffers/docs/proto3#json). | ||
| // | ||
| // While the single segment variable follows the semantics of | ||
| // [RFC 6570](https://tools.ietf.org/html/rfc6570) 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. | ||
| message HttpRule { | ||
| // Selects a method to which this rule applies. | ||

| // details. | ||
