javascript - 由于MIME类型错误，Chrome拒绝执行AJAX脚本(Chrome refuses to execute an AJAX script due to wrong MIME type)

Question

I'm trying to access a script as JSON via AJAX, which works fine on Safari and other browsers but unfortunately will not execute in Chrome.

(我正在尝试通过AJAX以JSON格式访问脚本，该脚本在Safari和其他浏览器上可以正常运行，但不幸的是无法在Chrome中执行。)

It's coming with the following error:

(它带有以下错误：)

Refused to execute script from '*' because its MIME type ('application/json') is not executable, and strict MIME type checking is enabled.

(拒绝从“ *”执行脚本，因为其MIME类型（“ application / json”）不可执行，并且启用了严格的MIME类型检查。)

Here's the request:

(这是请求：)

$.ajax({
    url: "http://some_url/test.json?callback=?",
    type: "GET",
    dataType: 'json',
    cache: true,
    success: function (data, status, error) {
      console.log('success', data);
    },
    error: function (data, status, error) {
      console.log('error', data, status, error);
    }
});

Does anyone have a workaround for this?

(有人对此有解决方法吗？)

By adding a callback argument, you are telling jQuery that you want to make a request for JSONP using a script element instead of a request for JSON using XMLHttpRequest.

(通过添加一个回调参数，您告诉jQuery您想使用脚本元素而不是XMLHttpRequest来请求JSONP。)

JSONP is not JSON.

(JSONP不是JSON。)

It is a JavaScript program.

(这是一个JavaScript程序。)

Change your server so it outputs the right MIME type for JSONP which is application/javascript .

(更改服务器，使其为JSONP输出正确的MIME类型，即application/javascript 。)

(While you are at it, stop telling jQuery that you are expecting JSON as that is contradictory: dataType: 'jsonp' ).

(（尽管如此，请不要告诉jQuery您期望使用JSON，因为这是矛盾的： dataType: 'jsonp' ）。)
