Expands headers supplied in the
value. Variables to the the right of the colon are expanded.
@Headers("Content-Type: application/xml")
interface SoapApi {
...
@RequestLine("GET /")
@Headers("Cache-Control: max-age=640000")
...
@RequestLine("POST /")
@Headers({
"X-Foo: Bar",
"X-Ping: {token}"
}) void post(@Param("token") String token);
...
Notes:
- If you'd like curly braces literally in the header, urlencode them first.
- Headers do not overwrite each other. All headers with the same name will be included
in the request.
Relationship to JAXRS The following two forms are identical.
Feign:
@RequestLine("POST /")
@Headers({
"X-Ping: {token}"
}) void post(@Named("token") String token);
...
JAX-RS:
@POST @Path("/")
void post(@HeaderParam("X-Ping") String token);
