JQuery的Ajax函数在Chrome中工作，但在Firefox中返回404

Question

我正在使用中央ajax函数向服务器发送ajax Post请求。这是函数的代码：

function postJson(url, jsObj, whenSuccess, whenError){ 
     $.ajax({ 
      type: "post", 
      headers: { 
       "Accept": "application/json, text/javascript, */*; q=0.01", 
       "Content-Type": "application/json, text/javascript, */*; q=0.01" 
      }, 
      dataType: "json", 
      url: url, 
      data: JSON.stringify(jsObj), 
      success: function(result){ 
       if(whenSuccess !== undefined){ whenSuccess(result); } 
      }, 
      error: function(xhr){ 
       if(whenError !== undefined){ whenError(xhr.status); } 
      } 
     }); 
    } 

当我尝试运行我的应用程序工作在铬罚款，但在Firefox它抛出一个404我的REST服务助手返回404时，接受或内容类型ISN “T设置为JSON ...所以我认为Firefox的可能不添加标题，但是当我看到所发送的请求：

Request URL: 
http://localhost:9081/api/1/localize/validation.json 

Request Method: 
POST 

Status Code: 
HTTP/1.1 404 Not Found 

Request Headers 
08:40:10.000 

X-Requested-With:XMLHttpRequestUser-Agent...... 
Referer:http://localhost:9081/kportal/ 
Pragma:no-cacheHost:localhost:9081 
Content-Type:application/json, text/javascript; charset=UTF-8, */*; q=0.01 
Content-Length:2 
Connection:keep-alive 
Cache-Control:no-cache 
Accept-Language:en-US,en;q=0.5 
Accept-Encoding:gzip, deflate 
Accept:application/json, text/javascript, */*; q=0.01 

你可以看到必要的标头设置。尽管如此，我仍然在Firefox中获得404，但不是在Chrome中。

有什么想法？

试试这个，

function postJson(url, jsObj, whenSuccess, whenError){ 
    $.ajax({ 
     type: "post", 
     contentType: "application/json; charset=utf-8", 
     accepts: { 
      xml: 'text/xml', 
      text: 'text/plain' 
     }, 
     dataType: "json", 
     url: url, 
     data: JSON.stringify(jsObj), 
     success: function(result){ 
      if(whenSuccess !== undefined){ whenSuccess(result); } 
     }, 
     error: function(xhr){ 
      if(whenError !== undefined){ whenError(xhr.status); } 
     } 
    }); 
}
