我有一个涉及的设置
前端服务器(Node.js,domain:localhost:3000)<--->后端(Django,Ajax,域:localhost:8000)
浏览器< - webapp < - Node.js(服务应用)
浏览器(webapp) - > Ajax - > Django(服务ajax POST请求)
现在,我的问题在于CORS设置,webapp使用它来向后端服务器进行Ajax调用.在chrome中,我一直在努力
当credentials标志为true时,无法在Access-Control-Allow-Origin中使用通配符.
在Firefox上也不起作用.
我的Node.js设置是:
var allowCrossDomain = function(req, res, next) {
res.header('Access-Control-Allow-Origin', 'http://localhost:8000/');
res.header('Access-Control-Allow-Credentials', true);
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
};

webapp发出如下请求:
$.ajax({
type: "POST",
url: 'http://localhost:8000/blah',
data: {},
xhrFields: {
withCredentials: true
},
crossDomain: true,
dataType: 'json',
success: successHandler
});

因此,webapp发送的请求标头如下所示:
Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: "Origin, X-Requested-With, Content-Type, Accept"
Access-Control-Allow-Methods: 'GET,PUT,POST,DELETE'
Content-Type: application/json
Accept: */*
Accept-Encoding: gzip,deflate,sdch

所以现在我继续编写一个简单的Test.aspx来使用这个新的Web API.脚本的相关部分:
<script type="text/javascript">
$(function () {
$.ajax({
url: "http://mywebapidomain.com/api/user",
type: "GET",
contentType: "json",
success: function (data) {
$.each(data, function (index, item) {
....
});
}
);
},
failure: function (result) {
alert(result.d);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("An error occurred, please try again. " + textStatus);
}
});
});
</script>
