Question

我正在使用resteasy。这是删除资源的代码。

@DELETE
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@Path("/{id:\\d+}")
public Response removeResource(@PathParam("id") int id){
    .........................
    .. code to delete resource and return Response object ..
    .........................
}

此代码工作正常。但是当我尝试传递一些参数来删除请求时。我得到了UnsupportedMediaException

@DELETE
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@Path("/{id:\\d+}")
public Response removeResource(@PathParam("id") int id, Map<String, Object> source){
    .........................
    .. code to delete resource and return Response object ..
    .........................
}

出于某种原因，我需要发送一些参数。此外，当我仅使用delete请求替换put请求，即将@DELETE替换为@PUT时，代码运行正常。

有没有办法将参数传递给删除请求。

在前端，我使用angularjs的$ resource发送DELETE请求

var r = $Resource(/rest/resources/1);    // for debugging purpose I made id 1
r.remove({"key1":"data1", "key2", "data2"});

您已请求Content-Type为“application / json” AngularJS defaults到text / plain。

如果您有足够新版本的AngularJS（1.1.3），则可以自定义资源对象以包含您请求的Content-Type。您应该能够修改资源定义以包含删除请求的Content-Type

var r = $Resource(/rest/resources/1, {},
   remove:{
      method:"DELETE",
      isArray:false,
      headers:{'Content-Type':'application/json; charset=UTF-8'} 
   }
);
