public final class HttpRule
extends com.google.protobuf.GeneratedMessageV3
implements HttpRuleOrBuilder

 `HttpRule` defines the mapping of an RPC method to one or more HTTP
 REST APIs.  The mapping determines what portions of the request
 message are populated from the path, query parameters, or body of
 the HTTP request.  The mapping is typically specified as an
 `google.api.http` annotation, see "google/api/annotations.proto"
 for details.
 The mapping consists of a field specifying the path template and
 method kind.  The path template can refer to fields in the request
 message, as in the example below which describes a REST GET
 operation on a resource collection of messages:
     service Messaging {
       rpc GetMessage(GetMessageRequest) returns (Message) {
         option (google.api.http).get = "/v1/messages/{message_id}/{sub.subfield}";
       }
     }
     message GetMessageRequest {
       message SubMessage {
         string subfield = 1;
       }
       string message_id = 1; // mapped to the URL
       SubMessage sub = 2;    // `sub.subfield` is url-mapped
     }
     message Message {
       string text = 1; // content of the resource
     }
 The same http annotation can alternatively be expressed inside the
 `GRPC API Configuration` YAML file.
     http:
       rules:
         - selector: <proto_package_name>.Messaging.GetMessage
           get: /v1/messages/{message_id}/{sub.subfield}
 This definition enables an automatic, bidrectional mapping of HTTP
 JSON to RPC. Example:
 HTTP | RPC
 -----|-----
 `GET /v1/messages/123456/foo`  | `GetMessage(message_id: "123456" sub: SubMessage(subfield: "foo"))`
 In general, not only fields but also field paths can be referenced
 from a path pattern. Fields mapped to the path pattern cannot be
 repeated and must have a primitive (non-message) type.
 Any fields in the request message which are not bound by the path
 pattern automatically become (optional) HTTP query
 parameters. Assume the following definition of the request message:
     message GetMessageRequest {
       message SubMessage {
         string subfield = 1;
       }
       string message_id = 1; // mapped to the URL
       int64 revision = 2;    // becomes a parameter
       SubMessage sub = 3;    // `sub.subfield` becomes a parameter
     }
 This enables a HTTP JSON to RPC mapping as below:
 HTTP | RPC
 -----|-----
 `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 HTTP parameters must have a
 primitive type or a repeated primitive type. Message types are not
 allowed. In the case of a repeated type, the parameter can be
 repeated in the URL, as in `...?param=A&param=B`.
 For HTTP method kinds which 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) = {
           put: "/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 | RPC
 -----|-----
 `PUT /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) = {
           put: "/v1/messages/{message_id}"
           body: "*"
         };
       }
     }
     message Message {
       string message_id = 1;
       string text = 2;
     }
 The following HTTP JSON to RPC mapping is enabled:
 HTTP | RPC
 -----|-----
 `PUT /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 of
 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 | RPC
 -----|-----
 `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
 The rules for mapping HTTP path, query parameters, and body fields
 to the request message are as follows:
 1. The `body` field specifies either `*` or a field path, or is
    omitted. If omitted, it assumes there is no HTTP body.
 2. Leaf fields (recursive expansion of nested messages in the
    request) can be classified into three types:
     (a) Matched in the URL template.
     (b) Covered by body (if body is `*`, everything except (a) fields;
         else everything under the body field)
     (c) All other fields.
 3. URL query parameters found in the HTTP request are mapped to (c) fields.
 4. Any body sent with an HTTP request can contain only (b) fields.
 The syntax of the path template is as follows:
     Template = "/" Segments [ Verb ] ;
     Segments = Segment { "/" Segment } ;
     Segment  = "*" | "**" | LITERAL | Variable ;
     Variable = "{" FieldPath [ "=" Segments ] "}" ;
     FieldPath = IDENT { "." IDENT } ;
     Verb     = ":" LITERAL ;
 The syntax `*` matches a single path segment. It follows the semantics of
 [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
 Expansion.
 The syntax `**` matches zero or more path segments. It follows the semantics
 of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.3 Reserved
 Expansion. NOTE: it must be the last segment in the path except the Verb.
 The syntax `LITERAL` matches literal text in the URL path.
 The syntax `Variable` matches the entire path as specified by its template;
 this nested template must not contain further variables. If a variable
 matches a single path segment, its template may be omitted, e.g. `{var}`
 is equivalent to `{var=*}`.
 NOTE: the field paths in variables and in the `body` must not refer to
 repeated fields or map fields.
 Use CustomHttpPattern to specify any HTTP method that is not included in the
 `pattern` field, such as HEAD, or "*" to leave the HTTP method unspecified for
 a given URL path rule. The wild-card rule is useful for services that provide
 content to Web (HTML) clients.
