[英]Respond with script from a Rails API app with limited middleware (config.api_only = true)?
I have a Rails 5 app build as an api app . 我有一个Rails 5应用程序构建为api应用程序 。 So by default it only responds with json.
因此,默认情况下,它仅以json响应。
But for one specific request I need the app to respond with a script. 但是对于一个特定的请求,我需要该应用使用脚本来响应。
In a regular Rails app I would simply put my script in a js.erb
file. 在常规的Rails应用程序中,我只是将脚本放入
js.erb
文件中。 This won't work here. 这在这里不起作用。
If my controller action looks like this: 如果我的控制器动作如下所示:
def respond_with_js
end
and I request the app like this: 我要求这样的应用程序:
$.getScript("https://myapp.example.com/respond_with_js");
it responds with 204 No Content
: 它以
204 No Content
响应:
Started GET "/respond_with_js" for 127.0.0.1 at 2018-06-27 20:28:44 +0200
Processing by ApplicationController#respond_with_js as */*
Completed 204 No Content in 0ms
How do I work around this? 我该如何解决?
You cannot request as script, if rails server is only api version. 如果Rails服务器仅是api版本,则不能作为脚本请求。
Rails by default responds json. 默认情况下,Rails响应json。
def respond_with_json
render json: {message: "works"}, status: :ok
end
To request it, you need to request as json dataType: 要请求它,您需要请求为json dataType:
$.ajax({
url: "https://myapp.example.com/respond_with_json",
method: "GET",
dataType: "json",
success: function(res){
console.log(res.message)
}
})
