预飞行的响应具有无效的HTTP状态代码400

Question

我正在尝试使用Ajax进行REST调用(POST)。这是我的AJAX代码

<script>
var settings = {
"async": true,
"crossDomain": true,
"dataType": "json",
"url": "http://localhost:port/service/myservice",
"method": "POST",
"data": '{jsondata}',
"headers": {
      "accept": "application/json",
      "Authorization": "authValue"
  }
}

$.ajax(settings)

.done(function (response) {
  console.log(response);
});
</script>

最初，我得到了这个错误：XMLHttpRequest无法加载http：//localhost：port/service/myservice。对preflight请求的响应未通过访问控制检查：请求的资源上没有“access-control-allow-origin”标头。因此不允许访问源“null”。响应的HTTP状态代码为400。

Dynamic filter = env.servlets().addFilter("CORS", CrossOriginFilter.class);

filter.setInitParameter(CrossOriginFilter.ALLOWED_METHODS_PARAM, "GET,PUT,POST,DELETE,OPTIONS");
filter.setInitParameter(CrossOriginFilter.ALLOWED_ORIGINS_PARAM, "*");
    filter.setInitParameter(CrossOriginFilter.ACCESS_CONTROL_ALLOW_ORIGIN_HEADER, "*");
filter.setInitParameter("allowedHeaders", "Content-Type,Authorization,X-Requested-With,Content-Length,Accept,Origin");
filter.setInitParameter("allowCredentials", "true");

filter.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), true, "/*");

你可以试试这里提到的完整答案在这个线程。

$.ajax({
        type:"POST",
        beforeSend: function (request)
        {
            request.setRequestHeader("Authority", authValue);
        },
        url: "http://localhost:port/service/myservice",
        data: "json=" + escape(JSON.stringify(createRequestObject)),
        processData: false,
        success: function(msg) {
            $("#results").append("The result =" + StringifyPretty(msg));
        }
});
