Question

我尝试从我的js调用我的java后端

angular 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（应该回复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();

我得到了这个例外：

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

问题在于您的资源文件，您不会发送任何您正在使用的内容。如果您要发送回复，那么您的返回类型应为“响应”，您还需要使用。

@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，如果您要发送语音类型，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();
    } 
}

无法将数据从cline发送到服务器
