我正在尝试让葡萄 API 以 json 格式回答其所有动词。问题是我无法回答 json 格式的路由错误。我什至无法挽救 ActionController::RoutingError。
我已阅读此链接https://github.com/intridea/grape/pull/342并将级联指令设置为 false,但 API 仅以纯文本形式回答“未找到”。
$ curl -X GET http://localhost:3000/api/wrong_uri
Not Found
带有详细选项:
$ curl -X GET http://localhost:3000/api/wrong_uri -v
