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. + // + // Refer to [selector][google.api.DocumentationRule.selector] for syntax + // details. + string selector = 1; + + // Determines the URL pattern is matched by this rules.
