是否可以在js< script>上设置自定义标头要求? [英] is it possible to set custom headers on js <script> requests?

问题描述

这样可能吗?

<script src="http://myserver.com/some.js" my-custom-header="foo"></script>

更新(更多细节):

有人问我是否有一种方法，可以使用标头而不是GET参数将某些参数作为脚本请求的一部分传达给服务器.我说:不，"但以为我会仔细检查.

I've been asked if there was a way to communicate some parameters to the server as part of the script request using headers instead of GET params. I said, "no," but thought I'd double check.

推荐答案

简短答案:否.默认情况下，脚本标记将仅检索src属性中指定的资源.

Short answer: no. By default a script tag will just retrieve the resource specified in the src attribute.

但是，如果您使用AJAX请求来检索脚本(并在以后添加/执行它)，则可以使用XMLHttpRequest对象的setRequestHeader函数(请参见

However, if you use an AJAX request to retrieve the script (and add it later/execute it), you can use the setRequestHeader function of the XMLHttpRequest object (see http://www.developertutorials.com/learn-ajax/custom-http-headers-2643.php).

您还可以使用更复杂的方法，例如使用mod_rewrite重写路径，并将参数包括在url中.最佳解决方案取决于您要执行的操作以及对服务器的控制权.

You could also use more complex methods, such as using mod_rewrite to rewrite paths, and include the parameters in the url. The best solution depends on what you want to do, and how much control you have over the server.
