angularjs – XMLHttpRequest无法加载…预检的响应具有无效的HTTP状态代码401

2019年7月21日 146次阅读

以下是我正在尝试进行基本身份验证的服务电话.我检查了多个博客无法找到解决方案.

当我收到以下错误时,有人可以帮我解决这个问题：

XMLHttpRequest cannot load

Response for preflight has invalid HTTP status code 401

我也无法在开发人员选项的网络选项卡中找到基本身份验证.

function() {
    "use strict";
    var APIservice = function($http, $base64) {
        var getDetails = function(postData) {
            $http.defaults.headers.common['Access-Control-Allow-Origin'] = "*";
            $http.defaults.headers.common['Access-Control-Allow-Methods'] = "GET,PUT,POST,DELETE,OPTIONS";
            $http.defaults.headers.common['Access-Control-Allow-Headers'] = "Content-Type, Authorization, Content-Length, X-Requested-With";
            $http.defaults.headers.common['Content-Type'] = undefined;
            console.log($http.defaults.headers.common.Authorization);
            //console.log($http.defaults.headers.common.Authorization);
            return $http.get('http://52.74.68.202:8080/rest/v1/step/all')
                .then(function(response, headers, config) {
                    console.log(response);
                    return response;
                });
        };
        return {
            getDetails: getDetails
        }
    }
    var module = angular.module('expframework');
    module.factory("APIservice", APIservice);
    module.run(['$http', '$base64', function($http, $base64) {
        var authdata = $base64.encode('test:test');
        $http.defaults.headers.common['Authorization'] = 'Basic ' + authdata;
    }]);
    module.config(['$httpProvider', '$base64', function($httpProvider, $base64) {
        var authdata = $base64.encode('test:test');
        $httpProvider.defaults.headers.common['Authorization'] = 'Basic ' + authdata;
    }])
}();

它适用于Safari和模拟器,但不适用于Chrome和Firefox

请帮我解决这个问题.提前致谢.

最佳答案 由于你的服务器扔了401,我猜它试图验证预检请求.从
https://stackoverflow.com/a/15734032/1225328开始：

The 07001 clearly states that user credentials should be excluded.

[…]

Simply have the server (API in this example) respond to OPTIONS requests without requiring authentication.
