Question

使用AngularJS和手机演示应用程序时，我试试这个：

var phonecatServices = angular.module('phonecatServices', ['ngResource']);

phonecatServices.factory('Phone', function($http) {
var myService = {
   query: function() {
// $http returns a promise, which has a then function, which also returns a promise
    var promise = $http.get('http://192.122.122.1:4040/data/json/').then(function (response) {
    // The then function here is an opportunity to modify the response
    console.log(response.data);
    // The return value gets picked up by the then in the controller.
    return response.data;
    });
// Return the promise to the controller
return promise;
}
};
return myService;
});

然后我按照原始示例尝试这种替代方法：

phonecatServices.factory('Phone', ['$resource',
function($resource){
 ar x= $resource('http://192.122.122.1:4040/data/json/', {}, {
 query: {method:'GET', isArray:false}
 });
 console.log(x)
 return x;
 }]);

然后我在Chrome和Firefox中得到这个：

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access.
HTTP/1.1 302 Found

我在Jetty servlet中定义了这些：

response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate")
      response.addHeader("Access-Control-Allow-Origin", "*");
      response.addHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE, HEAD");
      response.addHeader("Access-Control-Allow-Headers", "X-PINGOTHER, Origin, X-Requested-With, Content-Type, Accept");
      response.addHeader("Access-Control-Max-Age", "1728000");

当我卷曲时：

User-Agent: curl/7.35.0
Host: 192.122.122.1:4040
Accept: */*

HTTP/1.1 200 OK
Content-Type: text/json;charset=UTF-8
Cache-Control: no-cache, no-store, must-revalidate
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE, HEAD
Access-Control-Allow-Headers: X-PINGOTHER, Origin, X-Requested-With, Content-Type,     Accept
Access-Control-Max-Age: 1728000
Content-Length: 38
* Server Jetty(8.1.14.v20131031) is not blacklisted
Server: Jetty(8.1.14.v20131031)

{
 "a" : "b"
}

请有人帮我这个吗？

Answer 1

原来我的servlet被绑定了

http://192.122.122.1:4040/data/json/

我正在打电话

http://192.122.122.1:4040/data/json (without the last slash) .

这导致重定向-302 - 角度不满意。

Angularjs资源和http 302和Access-Control-Allow-Origin
