我正在使用 AngularJS 1.2.20。
每当我使用该$http
服务从 URL(不同的域/服务器)访问 zip 文件时,它都会给我一个错误,如下所示:
XMLHttpRequest cannot load http://localhost/ABC/updates.zip. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.
我尝试在模块的配置中设置以下内容:
$httpProvider.defaults.useXDomain = true;
$httpProvider.defaults.withCredentials = true;
delete $httpProvider.defaults.headers.common["X-Requested-With"];
$httpProvider.defaults.headers.common["Accept"] = "application/json";
$httpProvider.defaults.headers.common["Content-Type"] = "application/json";
但这仍然会引发错误。
我的代码片段是:
$http({method: 'GET', url: paths.categoryUpdateURL}).
success(function(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
alert("download Complete")
}).
error(function(data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
alert("error")
});
应该做些什么来防止这种情况发生?
