我有简单的 Controller 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'
}
}
注册表:
<!-- 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。当使用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

使用浏览器访问/register 返回表单。但是当我在浏览器中提交它时，返回了 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 确认已执行 POST:
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，如何修复它..

更新
我发现请求正文很重要。使用curl不带body发送请求成功，但设置body导致请求失败。好的:
$ 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:

还有什么区别吗？
最佳答案
我解决了一个奇怪的问题。
Grails 渲染 <g:actionSubmit value="Register" />如
<input type="submit" value="Register" name="_action_Register">
注意这个奇怪的名字。 Grails 从 value 推断出它属性并在选择要调用的操作时使用它。在我的情况下它会导致问题，因为 POST /register应由 save 处理行动。
将其更改为 <input type="submit" value="Register">解决问题。
