如何检测请求是否为 AJAX 请求？
检查以下代码是否适用于所有浏览器：
req.Header.Get("X-Requested-With")
英文:
How can I detect, if a request is an AJAX or not?
Would checking
req.Header.Get("X-Requested-With")
work for all browser?

很遗憾，“X-Requested-With”并不总是可靠的。如果你控制着发起Ajax请求，你可以使用beforeSend函数来确保设置这个值：
$.ajax({
url: "http://localhost/url",
data: { signature: authHeader },
type: "GET",
beforeSend: function(xhr){xhr.setRequestHeader('X-Requested-With', 'xmlhttprequest');},
success: function() { alert('Success!' + authHeader); }
});
然后你可以检查req.Header.Get("X-Requested-With") == 'xmlhttprequest'。

Unfortunately "X-Requested-With" is not always reliable. If you are in control of making the Ajax call you may use the beforeSend function to ensure this is set:
$.ajax({
url: "http://localhost/url",
data: { signature: authHeader },
type: "GET",
beforeSend: function(xhr){xhr.setRequestHeader('X-Requested-With', 'xmlhttprequest');},
success: function() { alert('Success!' + authHeader); }
});
You may then check if req.Header.Get("X-Requested-With") == 'xmlhttprequest'
