我有简单的控制器代码,例如:
// UserController.groovy
class UserController {
static allowedMethods = [
signIn: 'GET',
authenticate: 'POST',
signOut: 'POST',
register: 'GET',
save: 'POST'
]
// ... code omitted
def register() { }
def save() {
render 'ok'
}
}
报名表格:
<!-- register.gsp -->
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="layout" content="main" />
<title>Withme: Register</title>
</head>
<body>
<g:form mapping="register">
<!-- Code omitted -->
<g:actionSubmit value="Register" />
</g:form>
</body>
</html>
和 url 映射:
//UrlMappings.groovy
class UrlMappings {
static mappings = {
name register: '/register'(controller: 'user') {
action = [GET: 'register', POST: 'save']
}
}
}
现在是奇怪的部分。使用 curl 发出请求时,一切都按预期工作:
$ curl http://localhost:8080/withme/register -X GET -v -L
... form rendered ...
$ curl http://localhost:8080/withme/register -X POST -v -L
< HTTP/1.1 200 OK
< Server: Apache-Coyote/1.1
< Content-Type: text/html;charset=utf-8
< Transfer-Encoding: chunked

<
* Connection #0 to host localhost left intact
ok* Closing connection #0
使用浏览器访问 /register 会返回表单。但是当我在浏览器中提交它时,返回 405!
HTTP Status 405 -
type Status report
message
description The specified HTTP method is not allowed for the requested resource.
Apache Tomcat/7.0.42
Firebug 确认 POST 已执行:
POST http://localhost:8080/withme/register | 405 Method Not Allowed | localhost:8080
我已禁用应用程序中的所有过滤器。
我想知道 curl 和浏览器 POST 请求有什么区别?为什么 grails 以不同的方式处理它?最后,如何解决它..
Grails 2.2.4 Groovy 版本:2.1.6 JVM:1.7.0_21 供应商:Oracle Corporation 操作系统:Mac OS X
更新
我发现请求正文很重要。使用没有正文的 curl 发送请求成功,但设置正文会导致请求失败。好一个:
$ curl http://localhost:8080/withme/register -X POST -v -L

* Trying ::1...
* connected
* Connected to localhost (::1) port 8080 (#0)

还有一个不好的:

还是有什么区别?
