Question

您好我正在使用dropwizard和angularjs进行演示应用，但面临＆＃34; 500（内部服务器错误）＆＃34;的问题。

index.html：

<!DOCTYPE html>
<html ng-app="ttApplication">
<script src="js/lib/angular.min.js"></script>
    <script src="js/controller/commonController.js"></script>
    <body>

        <div ng-controller="initCtrl">
            <p>Name: <input type="text" ng-model="name"></p>
            <p>password: <input type="text" ng-model="password"></p>
            <button ng-click="auth(name,password)">button</button>
        </div>

    </body>
</html>

commonController.js：

var app = angular.module('ttApplication', []);

    app.controller('initCtrl', function($scope,$http) {
       $scope.auth =function(userId,password){
           $http.post('api/service/auth', {
               name: userId,
               password: password
           }).then(function(response) {}, function(err) {
               return err;
           });
       }
    });

[Dropwizard] userResource.java：

@Path("/service")
@Produces(MediaType.APPLICATION_JSON)
public class UserResource {
    final static Logger logger = LoggerFactory.getLogger(UserResource.class);
    private UserDao userdao;
    private Validator validator;

    public UserResource(DBI jdbi, Validator validator) {
        this.userdao=jdbi.onDemand(UserDao.class);
        this.validator=validator;

    }

    @POST
    @Path("/auth")
    public Response getUserDetails( User auth ){

        User user = userdao.findByEmail(auth.getEmail());

        if(user.getEmail().length()>0){
            PasswordEncryptor encrypt=new PasswordEncryptor();
            if(auth
                .getPassword()
                .equals(encrypt
                .passwordDecryption(user
                .getPassword()))){

                //logger.info("===================:successsss");
                return Response.ok(user.getName()).build();
            }else{
                return Response
                        .status(Status.BAD_REQUEST)
                        .entity("invalid password")
                        .build();
            }
        }
         return Response.ok(user.getName()).build();
    }

    @POST
    public Response postUserDetails(User user) throws URISyntaxException {
        PasswordEncryptor encryptor =new PasswordEncryptor();
        user.setPassword(encryptor.passwordEncryption(user.getPassword()));
        Set<ConstraintViolation<User>> violations =  validator.validate(user); 
        if(violations.size()>0){
            ArrayList<String> validationMessages = new ArrayList<String>();
            for (ConstraintViolation<User> violation : violations) { 
                    validationMessages
                    .add(violation.getPropertyPath().toString() +": " + violation.getMessage()); 
            }     
            return Response
                    .status(Status.BAD_REQUEST)
                    .entity(validationMessages)
                    .build();    
        }else {
            userdao.insert(user);
            return Response
                    .created(new URI(user.toString()))
                    .build();
        }

    }



}

我的问题是当我从html表单点击提交按钮然后它会抛出＆＃34; 500内部服务器错误＆＃34; 但当我通过＆＃34; postman＆＃34;检查我的服务时休息客户端它工作正常，给我结果。

请帮帮我!!当我通过HTML提交时，为什么它不起作用。

在您的帖子请求实施中，您正在通过电子邮件查找用户而您没有在commonController中设置该字段

User user = userdao.findByEmail(auth.getEmail());

commoncontroller

$scope.auth =function(userId,password){
       $http.post('api/service/auth', {
           name: userId,
           password: password
           email: <email>
       }).then(function(response) {}, function(err) {
           return err;
       });

我不知道你是如何实现userdao但我怀疑它返回一个空用户

抛出内部服务器错误-dropwizard和angularjs
