Http Server

Sets up an HTTP server that will send messages over HTTP(S) GET requests. HTTP 2.0 is supported when using TLS, which is enabled when key and cert files are specified.

Sets up an HTTP server that will send messages over HTTP(S) GET requests.

Three endpoints will be registered at the paths specified by the fields path, stream_path and ws_path. Which allow you to consume a single message batch, a continuous stream of line delimited messages, or a websocket of messages for each request respectively.

When messages are batched the path endpoint encodes the batch according to RFC1341.

Please note, messages are considered delivered as soon as the data is written to the client. There is no concept of at least once delivery on this output.

Please note that components within a Tyk config will register their respective endpoints in a non-deterministic order. This means that establishing precedence of endpoints that are registered via multiple http_server inputs or outputs (either within brokers or from cohabiting streams) is not possible in a predictable way.

This ambiguity makes it difficult to ensure that paths which are both a subset of a path registered by a separate component, and end in a slash (/) and will therefore match against all extensions of that path, do not prevent the more specific path from matching against requests.

It is therefore recommended that you ensure paths of separate components do not collide unless they are explicitly non-competing.

For example, if you were to deploy two separate http_server inputs, one with a path /foo/ and the other with a path /foo/bar, it would not be possible to ensure that the path /foo/ does not swallow requests made to /foo/bar.

Fields

address

An alternative address to host from. If left empty the service wide address is used.

Type: string
Default: ""

path

The path from which discrete messages can be consumed.

Type: string
Default: "/get"

stream_path

The path from which a continuous stream of messages can be consumed.

Type: string
Default: "/get/stream"

ws_path

The path from which websocket connections can be established.

Type: string
Default: "/get/ws"

allowed_verbs

An array of verbs that are allowed for the path and stream_path HTTP endpoint.

Type: array
Default: ["GET"]

timeout

The maximum time to wait before a blocking, inactive connection is dropped (only applies to the path endpoint).

Type: string
Default: "5s"

cert_file

Enable TLS by specifying a certificate and key file. Only valid with a custom address.

Type: string
Default: ""

key_file

Enable TLS by specifying a certificate and key file. Only valid with a custom address.

Type: string
Default: ""

cors

Adds Cross-Origin Resource Sharing headers. Only valid with a custom address.

Type: object

cors.enabled

Whether to allow CORS requests.

Type: bool
Default: false

cors.allowed_origins

An explicit list of origins that are allowed for CORS requests.

Type: array
Default: []
