Javascript ajax 调用在我的调用末尾添加“?=####”

Question

我有一个简单的 ajax 命令调用 URL 到我的服务器：

$.ajax({ type: "GET", url: "/action" });

我的日志的响应显示为 /action?_=1423024004825

有没有办法删除这个？

_=#### 是缓存破坏者。当您将缓存设置设置为 false 时，它会将其附加到查询字符串以使其成为新请求，而不是使用响应的缓存版本。

要阻止它被附加，只需将设置更改为 true（现在将使用缓存的响应）

jQuery.ajaxSetup({cache:true});

您还可以通过将缓存设置添加到选项来基于每个请求进行设置

jQuery.ajax({
    type: "GET", 
    url: "/action",
    cache:true 
});

http://api.jquery.com/jQuery.ajax

cache (default: true, false for dataType 'script' and 'jsonp')

Type: Boolean

If set to false, it will force requested pages not to be cached by the browser. Note: Setting cache to false will only work correctly with HEAD and GET requests. It works by appending "_={timestamp}" to the GET parameters. The parameter is not needed for other types of requests, except in IE8 when a POST is made to a URL that has already been requested by a GET.
