我正在对休息服务进行简单的jquery ajax调用。我将contentType设置为application / json,其余资源配置为接受 MediaType.APPLICATION_JSON 。这是一个POST方法。 使用此设置,我收到不支持的媒体类型错误。
I'm having a simple jquery ajax call to a rest service. I am setting the contentType as "application/json" and the rest resource is configured to accept "MediaType.APPLICATION_JSON". This is a POST method. With this setup, I am getting "Unsupported Media Type" error.
标题信息显示 请求标题中的Content-Type application / json; charset = UTF-8
The header info shows "Content-Type application/json; charset=UTF-8" in the request header
响应显示:状态报告:不支持的媒体类型服务器拒绝了此请求,因为请求实体的格式不受支持所请求方法的请求资源(不支持的媒体类型)。
Response shows: Status report: Unsupported Media Type The server refused this request because the request entity is in a format not supported by the requested resource for the requested method (Unsupported Media Type).
请提供一些指示来解决此问题。
Please provide some pointers to resolve this issue.
以下是代码段:
休息资源
@POST @Produces({MediaType.APPLICATION_JSON,MediaType.TEXT_HTML}) @Consumes({MediaType.APPLICATION_JSON,MediaType.TEXT_HTML}) public Response addPerson(MyJSONObj myObj) { //... // ... //... }jquery
$(document).ready(function() { /* put your stuff here */ $("#Button_save").click(function(){ var firstName = $('firstName').val(); var lastName = $('lastName').val(); var person = {firstName: firstName, lastName: lastName}; $.ajax({ url:'localhost:8080/sampleApplication/resources/personRestService/', type: 'POST', data: person, Accept : "application/json", contentType: "application/json", success:function(res){ alert("it works!"); }, error:function(res){ alert("Bad thing happend! " + res.statusText); } }); }); });FF Firebug中显示的标题

<我有同样的问题,我能够以这种方式解决它(参见 http:// www.weverwijk/wordpress/tag/jquery/ ):
$.ajax({ url:'localhost:8080/sampleApplication/resources/personRestService/', type:'POST', data: JSON.stringify(person), dataType: 'json', contentType: "application/json; charset=utf-8", success:function(res){ alert("it works!"); }, error:function(res){ alert("Bad thing happend! " + res.statusText); } });在Java方面,我添加了这些(参见 Access-Control-Allow-Origin ):
On Java side I added these (see Access-Control-Allow-Origin ):
@OPTIONS public Response testt(@Context HttpServletResponse serverResponse) { serverResponse.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD"); serverResponse.addHeader("Access-Control-Allow-Credentials", "true"); serverResponse.addHeader("Access-Control-Allow-Origin", "*"); serverResponse.addHeader("Access-Control-Allow-Headers", "Content-Type,X-Requested-With"); serverResponse.addHeader("Access-Control-Max-Age", "60"); return Response.ok().build(); } @POST @Produces(MediaType.APPLICATION_JSON) @Consumes(APPLICATION_JSON) public Response addPerson(MyJSONObj myObj, @Context HttpServletResponse serverResponse) serverResponse.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD"); serverResponse.addHeader("Access-Control-Allow-Credentials", "true"); serverResponse.addHeader("Access-Control-Allow-Origin", "*"); serverResponse.addHeader("Access-Control-Allow-Headers", "Content-Type,X-Requested-With"); serverResponse.addHeader("Access-Control-Max-Age", "60"); // ... // ... }结论
- JSON对象自动转换和转换(更多细节见为RESTful Web服务配置JSON )
- POST commit
- 跨域(Same-Origin-Policy)
- Firefox可以工作(参见@Option标签)
- JSON Object gets transfered and transformed automagically (more details see Configuring JSON for RESTful Web Services)
- POST commit
- Cross Domain (Same-Origin-Policy)
- Firefox works (see @Option tag)
