Question

我有简单的控制器代码，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：

<!-- 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>

和网址映射：

//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，所有工作都按预期进行：

$ 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/注册返回表单。但是当我在浏览器中提交它时，405返回了！

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

我在我的应用程序中禁用了所有过滤器。

我想知道curl和浏览器POST请求之间的区别是什么？为什么grails以不同的方式处理它？最后，如何解决它..

更新

我发现请求正文很重要。使用curl发送请求而无需成功，但设置正文会导致请求失败。好的：

$ curl http://localhost:8080/withme/register -X POST -v -L
* About to connect() to localhost port 8080 (#0)
*   Trying ::1...
* connected
* Connected to localhost (::1) port 8080 (#0)
> POST /withme/register HTTP/1.1

糟糕的一个：

$ curl http://localhost:8080/withme/register -X POST -v -L -d "email=&password=&passwordConfirmation=&firstName=&lastName=&country=&city=&_action_Register=Register"

还有什么区别？

Answer 1

我解决了奇怪的问题。

Grails将<g:actionSubmit value="Register" />呈现为

<input type="submit" value="Register" name="_action_Register">

请注意这个奇怪的名字。 Grails从value属性中推断出它，并在选择要调用的操作时使用它。这会导致我的问题，因为POST /register应由save操作处理。

将其更改为<input type="submit" value="Register">解决问题。

Grails的方法不允许'古怪
