angularjs - $ http.post返回422，带有angular和grails

Question

我正在使用grails 3.x作为 Restful 服务提供者。提供了一个简单的休息资源，例如:

@Resource(uri ='/users', readOnly = false, formats = ['json', 'xml'])
class User {
    String username
    String email
    String password
}

我已经通过curl成功测试了它，例如:

$ curl -H "Content-Type: application/json" -X POST -d "{\"username\":\"xyz\",\"password\":\"xyz\", \"email\":\"w@g.com\"}" http://localhost:8080/users
{"id":1,"email":"w@g.com","password":"xyz","username":"xyz"}

但是当我使用angularjs执行http post ajax调用时，

$http.post(url, {"username":"dummy", "password":"test", "email":"email@g.com"})
    .success(function(data, status, headers, config) {
        // $location.path('/listUsers');
        console.log("data " + data);
    }).error(function(data, status, headers, config) {
        console.log("error occured... " + status);                  
    });

即使使用相同的精确值，它始终会抛出422状态。

您可以按以下方式全局放置此标题:

angular.module('myApp', [])
        .config(function ($httpProvider) {
            $httpProvider.defaults.headers.put['Content-Type'] = 'application/json';
            $httpProvider.defaults.headers.post['Content-Type'] =  'application/json';
        })
