禁用Chrome本地域的同源策略

Question

我正在尝试在我的Mac OS 10.10机器上使用Chrome 45.0.2454.85(64位)对我正在开发的扩展进行本地*.dev样式域的跨源请求。

我无法通过testbox.dev获得消息，因为每次我执行以下代码时，我都会获得status的0值，而responseText总是空的。当尝试这些连接时，检查后台页面的视图显示控制台错误net::ERR_CONNECTION_REFUSED。

我尝试关闭所有的Chrome实例，然后使用命令open -a Google Chrome --args --disable-web-security重新启动，但仍然不工作。

我尝试了CORS Chrome扩展，所以我至少可以在本地服务器上测试，但这不起作用。

尝试用https://www.corsproxy.com/前缀我的api.example.com URL，但请求从未完成。

尝试使用cors-anywhere.herokuapp.com前缀，但我得到错误origin header required。为了解决这个问题，我尝试使用xhr.setRequestHeader('Origin', http + '//' + window.location.host);发送原点头，但Chrome不允许我继续错误Refused to set unsafe header "Origin"。

我尝试添加以下响应到我的服务器的Laravel控制器方法，但没有帮助:

return Response::json($stock, 200, ['Access-Control-Allow-Origin' => '*']);

    var port     = chrome.extension.connect({ name: 'XHRProxy_' });
    var settings = {
        method : 'GET',
        url    : url
    };
    var onSuccess;
    var onFailure;
    var self = {
        onSuccess: function (callback) {
            onSuccess = callback;
            return self;
        },
        onFailure: function (callback) {
            onFailure = callback;
            return self;
        }
    };
    port.onMessage.addListener(function (msg) {
        if (msg.status === 200 && typeof onSuccess === 'function') {
            onSuccess(msg.data, msg.xhr);
        } else if (typeof onFailure === 'function') {
            onFailure(msg.data, msg.xhr);
        }
    });
    port.postMessage(settings);
    return self;
};

content.js

// Localhost test domain.
proxyXHR.get('testbox.dev/api/XYZ/quantity')
            .onSuccess(function (data) {
                console.log(data);
            })
            .onFailure(function (data, xhr) {
                console.log("HTTP Error while retrieving data.", data, xhr.status);
            });
// Production server domain....produces same error as local domain test above.
proxyXHR.get('api.example.com/api/XYZ/quantity')
            .onSuccess(function (data) {
                console.log(data);
            })
            .onFailure(function (data, xhr) {
                console.log("HTTP Error while retrieving data.", data, xhr.status);
            });

如果我将URL从testbox.dev更改为我的生产URL api.example.com，我仍然会得到相同的跨源拒绝。

你知道这是怎么回事吗?

Answer 1

net::ERR_CONNECTION_REFUSED不是交叉原点错误。您可能有一些问题与您的https连接。您可以确保您的服务器上有正确的证书，或者切换到http。

注意下面这行:

    var http = (window.location.protocol === 'http:' ? 'http:' : 'https:');

在背景页面中没有多大意义，因为协议将始终是chrome-extension:。
