最近在项目中,前台页面使用jquery ajax访问后台CXF发布的rest服务,结果遇到了错误"Unsupported Media Type"。
发布的服务java代码如下:
import javax.jws.WebService; import javax.ws.rs.Consumes; import javax.ws.rs.GET; import javax.ws.rs.POST; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.core.Response; @WebService @Produces({ "application/json" }) public class TrackService { @POST @Path("/trackInBatch/") @Consumes("application/json") public Response postTrackInfoInBatch(List<TrackPosition> positions) { return retrieve(positions, clientGen, trafficMapLayerId, projectParaLayerId, "0"); } }
调用服务的javascript代码如下:
$.ajax({ url : "/myapp/rest/track/trackInBatch/", async:false, type : "POST", dataType:"json", data:[], error:function(XMLHttpRequest, textStatus, errorThrown){ alert(errorThrown); }, success: function(data, textStatus){ outResponse = data; } });
调用的服务的时候报错:Unsupported Media Type。通过HttpWatch查看原始的request和response报文,发现返回request报文中的contentType是:application/x-www-form-urlencoded。查看jquery.ajax()的API文档,发现contentType的默认值就是:application/x-www-form-urlencoded。
但是后台发布的rest服务,@Consumes("application/json")要求request报文的contentType必须是application/json。
手动设置contentType之后,发现问题解决。
$.ajax({ url : "/myapp/rest/track/trackInBatch/", async:false, type : "POST", dataType:"json", contentType:"application/json", data:[], error:function(XMLHttpRequest, textStatus, errorThrown){ alert(errorThrown); }, success: function(data, textStatus){ outResponse = data; } });
$.ajax访问RESTful Web Service报错:Unsupported Media Type
