jquery ajax rest call - 不支持的媒体类型

RJ.*_*RJ. 6 jquery xmlhttprequest http-headers

我有一个简单的jquery ajax调用休息服务.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.

标题信息 在请求标头中显示 "Content-Type application/json; charset = UTF-8"

响应显示:状态报告:不支持的媒体类型服务器拒绝此请求,因为请求实体的格式不受请求方法所请求的资源支持(不支持的媒体类型).

请提供解决此问题的一些指示.

这是代码片段:

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的

$(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:'http://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);
        }

我遇到了同样的问题,我能够以这种方式解决它(参见http://www.weverwijk.net/wordpress/tag/jquery/):

$.ajax({
    url:'http://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(请参阅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 对象自动传输和转换(更多详细信息请参阅为 RESTful Web 服务配置 JSON
  • POST提交
  • 跨域(同源策略)
  • Firefox 工作(见@Option 标签)

看起来您可能正遭受抽象漏洞的困扰。请参阅此响应: JQuery's getJSON() not set Accept header Correctly?

如果您正在进行跨域调用,那么由于 jQuery 从您那里抽象调用的方式,您似乎无法设置接受标头。

不过,您确实说服务器看到了正确的接受标头。这可能表明存在不同的问题。
