fix(codec): Remove custom content-type (#104)
This removes custom content-types in favor of just using `application/grpc`. There is some confusion around the specification but most grpc implementations ignore the `+` and anything after.

// 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:

||||
//

|
||||
// -----|-----
|
||||
// `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 {

//

||||
// `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 {

// }
|

// };
|

// }
|

// }
|

// 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

// 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.
|
||||
//

// no client library can support such complicated mapping.

# Google Cloud Pubsub example
|
||||
|
||||
This example will attempt to fetch a list of topics using the google
|
||||
gRPC protobuf specification. This will use an OAuth token and TLS to
|
||||
fetch the list of topics.
|
||||
|
||||
First, you must generate a access token via the [OAuth playground]. From here
|
||||
select the `Cloud Pub/Sub API v1` and its urls as the scope. This will start
|
||||
the OAuth flow. Then you must hit the `Exchange authorization code for tokens`
|
||||
button to generate an `access_token` which will show up in the HTTP response
|
||||
to the right under the `access_token` field in the response json.
|
||||
|
||||
Once, you have this token you must fetch your GCP project id which can be found
|
||||
from the main page on the dashboard. When you have both of these items you can
|
||||
run the example like so:
|
||||
|
||||
```shell
|
||||
GCP_AUTH_TOKEN="<access-token>" cargo run --bin gcp-client -- <project-id>
|
||||
```
