How to get Response headers in AJAX
提问by Anoop LL
I am using the following code for an AJAX call
我正在使用以下代码进行 AJAX 调用
$.ajax({
type: "POST",
url: "http://******/cxf/view/*****",
data: {*****},
headers: {*****},
success: function (dt, status, request) {
console.log(request.getAllResponseHeaders());
},
error: function (jqXHR, status) {
}
});
This is printing only content-type. In the developer console i can see number of headers in the response. How can i get those headers in AJAX
这仅打印内容类型。在开发人员控制台中，我可以看到响应中的标头数量。我如何在 AJAX 中获取这些标头

On your server you need to add
在您的服务器上，您需要添加
res.header("Access-Control-Expose-Headers", "header-you-want-to-expose");
and then you will be able to access it in the browser.
然后你就可以在浏览器中访问它了。

I used the samecode you used
我使用了您使用的相同代码
success: function (dt, status, request) {
console.log(request.getAllResponseHeaders());
Problem is not with Jquery or Ajax. Response headers are set by Server. The server you are sending the request to, is not setting the headers! Simple!!!!
问题不在于 Jquery 或 Ajax。响应头由服务器设置。您向其发送请求的服务器未设置标头！简单的！！！！
