讓我不斷收到此錯誤

1Resource解釋爲腳本，但與MIME類型application/JSON轉移。

我想用jQuery查詢來抓住我的json窗體一個單獨的域上的php文件這裏是我的php代碼。

json.php

<?php 
header('Content-type: application/json'); 
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5); 
echo json_encode($arr); 
?> 

這裏是我的jQuery

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script> 
<script type="text/javascript"> 

$(document).ready(function() { 

    var surl = "http://dropp.users35.interdns.co.uk/json.php"; 

     $.getJSON(surl, function(rtndata) { 
      console.log(rtndata); 
    }); 

}); 


</script> 

確定的，如果我在我的網址更改爲

http://dropp.users35.interdns.co.uk/json.php?callback=？

我然後得到這個錯誤?????

1Resource interpreted as Script but transferred with MIME type application/json. 

Answer 1

我相信回答你的問題涉及到使用JSONP，因爲它涉及到跨域腳本...

它在StackOverflow上幾個類似的問題討論： Resource interpreted as script but transferred with MIME type application/json. & parsererror

Answer 2

返回的JavaScript中是否沒有回調，無論我是否指定callback=：

$ curl -v http://dropp.users35.interdns.co.uk/json.php?callback=test_callback 
* About to connect() to dropp.users35.interdns.co.uk port 80 (#0) 
* Trying 83.170.124.37... connected 
* Connected to dropp.users35.interdns.co.uk (83.170.124.37) port 80 (#0)

{"a":1,"b":2,"c":3,"d":4,"e":5} 

，如果你想要的工作，必須有一個回調包裝你的JSON：

test_callback({"a":1,"b":2,"c":3,"d":4,"e":5});
