我使用的是 Play 2.2.1。我的路由文件中有以下路由配置:
OPTIONS /*path controllers.Application.options
GET / controllers.Application.index
...some more routes
我在应用程序 Controller 中进行了以下设置:
package controllers
import play.api.mvc._
object Application extends Controller {
def index = Action {
Ok(views.html.index())
}
def options = Action {
Ok("").withHeaders(
"Access-Control-Allow-Origin" -> "*",
"Access-Control-Allow-Methods" -> "GET, POST, PUT, DELETE, OPTIONS",
"Access-Control-Allow-Headers" -> "Accept, Origin, Content-type, X-Json, X-Prototype-Version, X-Requested-With",
"Access-Control-Allow-Credentials" -> "true",
"Access-Control-Max-Age" -> (60 * 60 * 24).toString
)
}
}
当我尝试使用curl 测试OPTIONS 请求时，它完全被 Play 忽略。
curl -X OPTIONS --include 'http://localhost:9000/foo/139'
我收到此错误:
HTTP/1.1 404 Not Found
Content-Type: text/html; charset=utf-8
Content-Length: 7045
<!DOCTYPE html>
<html>
<head>
<title>Action not found</title>
...some more head junk
<body>
<h1>Action not found</h1>
<p id="detail">
For request 'OPTIONS /foo/139'
</p>
<h2>
These routes have been tried, in this order:
</h2>
<div>
<pre><span class="line">1</span><span class="route"><span class="verb">GET</span><span class="path">/</span><span class="call">controllers.Application.index</span></span></pre>
... more routes but none of them are for the OPTIONS request
我在这里做错了什么？提前致谢!
最佳答案
使用 *path 段执行某些操作 - 即使什么都不做...
路线:
OPTIONS / controllers.Application.options(path: String ?= "")
OPTIONS /*path controllers.Application.options(path)
行动:
def options(path: String) = Action {
Ok("").withHeaders(
"Access-Control-Allow-Origin" -> "*",
"Access-Control-Allow-Methods" -> "GET, POST, PUT, DELETE, OPTIONS",
"Access-Control-Allow-Headers" -> "Accept, Origin, Content-type, X-Json, X-Prototype-Version, X-Requested-With",
"Access-Control-Allow-Credentials" -> "true",
"Access-Control-Max-Age" -> (60 * 60 * 24).toString
)
}
有效
关于playframework - Play 路由配置完全忽略 Http OPTIONS 请求，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20525178/
