问题描述
我正在使用apache httpd服务器托管客户端文件
I am using apache httpd server for hosting client side files
http://ipaddress:8010/
并且我的Nodejs服务器在http://ipaddress:8087
and my Nodejs server is running on http://ipaddress:8087
当我发送帖子请求时,它显示以下错误
when i am sending post request then it shows following error
XMLHttpRequest cannot load http://ipaddress:8010/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://ipaddress:8087' is therefore not allowed access.
我的客户端代码是:
$.ajax({
type: "POST",
url: "http://ipaddress:8010",
data: {name:"xyz"},
success: function(){
alert("success");
},
dataType: "json"
});
我的服务器端是:
response.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
response.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
response.setHeader('Access-Control-Allow-Credentials', true);
允许的选项仍然不起作用,有人可以提示问题出在哪里吗? 我在服务器端收到请求,但无法发送任何响应.
options allowed still it is not working can anybody suggest what exactly is the problem? i am receiving request on server side but not able to send any response.
提前感谢:)
推荐答案
错误消息显示:
您已经设置了三个Access-Control-Allow-SOMETHING
标头,但都不是Origin
.
You have set three Access-Control-Allow-SOMETHING
headers, but none of them is Origin
