否.

仅当您使用XMLHttpRequest或fetch进行请求时，才可以将自定义HTTP标头添加到请求中(因此，如果您使用表单提交来进行请求，则不能这样做).

You can only add custom HTTP headers to a request if you are using XMLHttpRequest or fetch to make the request (so you can't if you are using a form submission to make the request).

您可以使用 submit 事件来拦截表单提交，并使用XMLHttpRequest或fetch来发出请求………但是您也需要使用JS处理响应.

You could use the submit event to intercept the form submission and make the request with XMLHttpRequest or fetch instead … but then you'd need to handle the response with JS too.
