Ruby on Rails 对所有路由响应“无路由匹配”，而 rack routes 命令按预期显示它们
Ruby on Rails responds "no route matches" for all routes while rack routes command shows them as expected
问：
情况
我绝对是 Ruby 的新手，但对 Django、Node 和其他技术有一定的经验。 我正在尝试在我的本地运行我的雇主的遗留项目，该项目实际上是在生产中运行的。我做的第一件事是将其docker化。Puma 服务器启动良好，它连接到 postgres 数据库，对根 127.0.0.1：3000 的响应正常，带有 Rails 默认欢迎页面。甚至 swagger 也会显示预期的端点，甚至 /rails/info/routes 也会完美地显示路由。此外，耙子路由显示完全相同：
user@local:~/path_to/project$ sudo docker compose exec app rake routes
Prefix Verb URI Pattern Controller#Action api/v1/users#index
POST /api/users(.:format) api/v1/users#create
api_user GET /api/users/:id(.:format) api/v1/users#show
PATCH /api/users/:id(.:format) api/v1/users#update
PUT /api/users/:id(.:format) api/v1/users#update
DELETE /api/users/:id(.:format) api/v1/users#destroy
api_auth_login POST /api/auth/login(.:format) api/v1/authentication#login
但是当我向 /api/auth/login 发出请求时，它会响应：
{
"status": 404,
"error": "Not Found",
"exception": "#<ActionController::RoutingError: No route matches [POST] \"/api/auth/login\">",
"traces": {
"Application Trace": [],
"Framework Trace": [
{
"exception_object_id": 47259696989680,
"id": 0,
"trace": "actionpack (6.0.3.7) lib/action_dispatch/middleware/debug_exceptions.rb:36:in `call'"
},
{

"id": 1,
"trace": "actionpack (6.0.3.7) lib/action_dispatch/middleware/show_exceptions.rb:33:in `call'"
},

我不知道还能尝试什么。请帮忙！！

我没有意识到约束，现在正在寻找 ApiVersion 类......
class ApiVersion
attr_reader :version, :default
def initialize(version, default = false)
@version = version
@default = default
end
# check whether version is specified or is default
def matches?(request)
check_headers(request.headers) || default
end
private
def check_headers(headers)
accept = headers[:accept]
accept && accept.include?("application/vnd.some_string.#{version}+json")
end
end
所以添加标题
Accept: "application/vnd.some_string.v1+json"
做到了。

ApiVersion.new('v1')
