我正在使用AngularJS v1.2.4。
我有角发送预检OPTIONS调用的问题(Chrome的显示OPTIONS调用为“取消”),并解决它:
$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];
,对我所有的$的资源调用的工作,一切都很好。
现在我正在尝试实现身份验证,并使用用户凭据向我的服务器发送POST请求的登录页面。我看到我以前面临的问题,但$资源调用仍然正常工作。
真正令人沮丧的是,问题是间歇性地发生的;我将更改头部的一些选项,然后它会工作一段时间,并在没有任何代码更改的情况下再次停止工作。
我的服务器配置为CORS,并且可以很好地处理curl和其他REST客户端。这里有一个例子:
curl -X OPTIONS -ik 'https://localhost:3001/authenticate' -H "Origin: https://localhost:8001"
HTTP/1.1 200 OK
content-type: application/json; charset=utf-8

这里的$ http.post电话:
var authRequest = $http.post('https://' + $location.host() + ':3001/authenticate', {email: email, password: password});
当从我的应用程序工作的号召,这是OPTIONS请求的样子:
当它不起作用时,这是OPTIONS请求:
它看起来像一大堆的标题属性丢失。有没有人遇到类似的问题?
编辑:
只是为了澄清,当它不工作,从来没有要求它向服务器 - 它在浏览器立即中止。
在Firebug中,请求头是:

更新:
我已经与服务器消除了可能的问题,我觉得通过将主机更改为不存在的服务器。仍然看到相同的行为。
下面是一些代码:
App.services.factory('AuthService', function ($http, $location, $q) {
var currentUser;
return {
authenticate: function (email, password) {
//promise to return
var deferred = $q.defer();
var authRequest = $http.post('https://this.does.not.exist.com:3001/authenticate', {email: email, password: password});
authRequest.success(function (data, status, header, config) {
currentUser = data;
console.log('currentUser in service set to:');
console.log(currentUser);
//resolve promise
deferred.resolve();
});
authRequest.error(function (data, status, header, config) {
console.log('authentication error');
console.log(status);
console.log(data);
console.log(header);
console.log(config);
//reject promise
deferred.reject('authentication failed..');
});
return deferred.promise;
},
isAuthenticated: function() {
return currentUser !== undefined;
}
};
});
和HTTP配置:
App.config(['$httpProvider', function ($httpProvider) {
$httpProvider.defaults.useXDomain = true;
//$httpProvider.defaults.headers.common = {};
console.log('logging out headers');
console.log($httpProvider.defaults);
console.log($httpProvider.defaults.headers.common);
console.log($httpProvider.defaults.headers.post);
console.log($httpProvider.defaults.headers.put);
console.log($httpProvider.defaults.headers.patch);
console.log('end logging out headers');
$httpProvider.defaults.headers.common = {Accept: "application/json, text/plain, */*"};
$httpProvider.defaults.headers.post = {"Content-Type": "application/json;charset=utf-8"};
console.log('after: logging out headers');
console.log($httpProvider.defaults.headers.common);
console.log($httpProvider.defaults.headers.post);
console.log($httpProvider.defaults.headers.put);
console.log($httpProvider.defaults.headers.patch);
console.log('after: end logging out headers');
$httpProvider.interceptors.push(function ($location, $injector) {
return {
'request': function (config) {
console.log('in request interceptor!');
var path = $location.path();
console.log('request: ' + path);
//injected manually to get around circular dependency problem.
var AuthService = $injector.get('AuthService');
console.log(AuthService);
console.log(config);
if (!AuthService.isAuthenticated() && $location.path() != '/login') {
console.log('user is not logged in.');
$location.path('/login');
}
//add headers
console.log(config.headers);
return config;
}
};
});
}]);
你确定你的脚本/应用程序没有发送双重请求吗?同步(表单提交)+异步请求到相同的网址? – asumaran
@asumaran你能澄清吗?我很确定这只是一个单一的请求。 – shaunlim
使用Firebug来调试CORS问题。 Chrome有一个已知的问题,并不会显示所有可用的信息。 https://code.google.com/p/chromium/issues/detail?id=269192&q=CORS&colspec=ID%20Pri%20M%20Iteration%20ReleaseBlock%20Cr%20Status%20Owner%20Summary%20OS%20Modified – TheSharpieOne
