403使用AJAX进行PUT和DELETE时的状态（禁止）

问题描述

我使用JAX-RS（Jersey 2.0）实现了一个小型REST API，我使用AJAX来调用API，GET和POST工作正常但是当我调用任何PUT或DELETE方法时，我得到的只是是以下错误消息：

I've implemented a small REST API using JAX-RS (Jersey 2.0) and I'm using AJAX to call the API, GET and POST work fine but when I get to call any PUT or DELETE methods, all I get is the following error message:

以下是Java中 DELETE 方法的示例：

Here's an example of a DELETE method in Java:

    @Path("/deleteSomething")
    @DELETE
    @Consumes("application/json")
    public void delete(String json) throws ParseException {
        JSONParser parser = new JSONParser();
        Object obj = parser.parse( json );
        JSONObject object=(JSONObject)obj;

        String id = (String) object.get("id");
        System.out.println("ID  :   " + id);
        //DO SOMETHING HERE
    }

这里是Javascript调用AJAX：

And here is the Javascript call using AJAX:

function deleteSomethingAjax() {
    $.ajax({
        url: API_URI + "/deleteSomething", //API_URI is the API's uri
        contentType : 'application/json',
        data: idToJSON(), // this function just returns a JSON obj {"id":"myID"}
        type:  'DELETE',
        success : function(data, textStatus, jqXHR) {
            alert( "Fine!" );
        },

        error : function(jqXHR, data, textStatus, errorThrown) {
            alert('WOOPS, something wrent wrong...');
        }
    });
}

任何帮助都将不胜感激！谢谢!!

推荐答案

这个问题与CORSFilter设置有关，我在 web.xml 文件。以下是CORSFilter的一部分，设置在 web.xml 内：

The issue had to do with the CORSFilter set-up, I was setting it wrong in the web.xml file. Here is the part of the CORSFilter, well set inside web.xml:

<filter>
    <filter-name>CorsFilter</filter-name>
    <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
    <init-param>
        <param-name>cors.allowed.origins</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
        <param-name>cors.allowed.methods</param-name>
        <param-value>GET,POST,HEAD,OPTIONS,PUT,DELETE</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>CorsFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
