Question

我希望我的服务器向角度js客户端发送指示性错误。

我看到了这些例子：

Example 7
Project: spice   File: RequestService.java View source code 6 votes vote down vote up
@GET
@Path("date")
@Produces("text/plain")
public Response get(@Context Request request) {
    final Date modificDate = getLastModificationDateFromDatastore();
    final EntityTag entityTag = getEntityTagFromDatastore();
    final ResponseBuilder resp = request.evaluatePreconditions(modificDate,
            entityTag);
    if (resp != null) {
        return resp.build();
    }
    // Build new Response
    final ResponseBuilder responseBuilder = Response.status(200);
    responseBuilder.entity("This is the Entity from " + modificDate);
    responseBuilder.lastModified(modificDate);
    responseBuilder.tag(entityTag);
    return responseBuilder.build();
}

和

Example 8
Project: zeppelin   File: JsonResponse.java View source code    4 votes vote down vote up
public javax.ws.rs.core.Response build() {
  ResponseBuilder r = javax.ws.rs.core.Response.status(status).entity(this.toString());
  if (cookies != null) {
    for (NewCookie nc : cookies) {
      r.cookie(nc);
    }
  }
  return r.build();
}

但是当我的服务器代码发送时：

catch (Exception ex)
{

    String error = "RuntimeException: test11";
    logger.error("update voice filed. Error: "+error);

    return Response.serverError().entity(error).build();
}

在客户端代码中我找不到此错误消息：

            $http.put('api/foo', {voice : voice, isAddMode : isAddMode}).then(
                function successCallback(response) {
..
                }, function errorCallback(response) {
                    var responseStr = JSON.stringify(response)
                    console.log(responseStr);
                    deferred.reject(responseStr);
                });

我得到解析错误，但一般来说我找不到js中的正确成员。

SyntaxError: Unexpected token R in JSON at position 0
    at JSON.parse (<anonymous>)
    at fromJson (angular.js:1377)
    at defaultHttpResponseTransform (angular.js:11003)

    at Scope.$eval (angular.js:17972)

Answer 1

我不得不删除服务器端的"Produces"注释：

    @Path("/foo")
    @PUT
    @Consumes(MediaType.APPLICATION_JSON + ";charset=utf-8")
//    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")

然后从服务器发送了一个json对象，而不只是字符串。

angular js无法解析jax-rs响应
