Example

Default

  • Scope is https://www.googleapis.com/auth/cloud-platform
  • Looks for credentials in the following places, preferring the first location found:
    • A JSON file whose path is specified by the GOOGLE_APPLICATION_CREDENTIALS environment variable.
    • A JSON file in a location known to the gcloud command-line tool.
    • On Google Compute Engine, it fetches credentials from the metadata server.
// simple:
// gouth = { version = "x.x.x" }
let token = gouth::Token::new().unwrap();
println!("authorization: {}", token.header_value().unwrap());

// with tonic:
// gouth = { path = "x.x.x", features = ["tonic-intercept"] }
let mut service = PublisherClient::with_interceptor(channel, gouth::tonic::interceptor());
service.list_topics(...);

Custom

scope:

use gouth::Builder;

let token = Builder::new()
	.scopes(&["https://www.googleapis.com/auth/bigquery"])
	.build()
	.unwrap();
println!("authorization: {}", token.header_value().unwrap());

json:

use gouth::Builder;

let token = Builder::new().json("credentials-data").build().unwrap();
println!("authorization: {}", token.header_value().unwrap());

file:

use gouth::Builder;

let token = Builder::new().file("credentials-path").build().unwrap();
println!("authorization: {}", token.header_value().unwrap());
