无法将数据从客户端发送到服务器

jersey-2.0 angularjs java javascript

我尝试从js调用java后端

角js( http://localhost:8082/dev/index.html#/ ):

self.submit = function() {
  console.log("in voice prompt component - submit");
  console.log(self.voice);
  $http.put('localhost:8082/api/Voices/updateVoice', self.voice).then(
    function successCallback(response) {
      self.voices = response.data;
    },
    function errorCallback(response) {
      // called asynchronously if an error occurs
      // or server returns response with an error status.
      console.log(response); 
    });
}

java(应响应 localhost:8082/api/Voices/updateVoice

@Path("/Voices")
public class VoicesOperation {

...

    @Path("/updateVoice")
    @PUT
    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
    public void updateVoice(VoiceBl voice) throws Exception {

        fillVoicesSnapshot();

我得到这个js异常:

TypeError: 'caller' and 'arguments' are restricted function properties and cannot be accessed in this context.

问题是您的资源文件,您没有发送任何东西,也没有消费任何东西。如果您正在发送响应,那么您的返回类型应该是response,并且您还需要消费。

@Path("/Voices")
public class VoicesOperation {

...

    @Path("/updateVoice")
    @PUT
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
    public Response updateVoice(VoiceBl voice) throws Exception {
        Voice voice = fillVoicesSnapshot();
        return Response.status(Status.CREATED)
                       .entity(voice)
                       .build();
    }
}

或者,如果您发送的是语音类型,则返回类型应为语音。

@Path("/Voices")
public class VoicesOperation {

...

    @Path("/updateVoice")
    @PUT
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
    public Voice updateVoice(VoiceBl voice) throws Exception {

        return fillVoicesSnapshot();
    } 
}
