auth.js:84交叉来源读取阻塞(CORB)阻止跨原点响应 http://myserver/auth 与MIME类型的应用程序/json。

这也不适用于Firefox，尽管Firefox错误消息更通用。奇怪的是，Firefox的网络面板显示，我想要的响应实际上被传递了，浏览器只是不接受将它传递给我的JavaScript代码的响应。

这是从我的 krakend.json 文件中设置的CORS：

        "github_com/devopsfaith/krakend-cors": {
            "allow_origins": ["http://localhost:61552"],
            "allow_headers": ["Origin", "Authorization", "Content-Type", "Accept", "X-Auth-Token", "Referer", "User-Agent"],
            "expose_headers": ["Content-Type", "Content-Length"],
            "allow_credentials": true,
            "allow_methods": ["GET", "HEAD", "POST", "OPTIONS"]
        }

这是被调用的特定端点：

    "endpoints": [{
            "endpoint": "/auth",
            "method": "POST",
            "output_encoding": "no-op",
            "extra_config": {
                "github.com/devopsfaith/krakend-ratelimit/juju/router": {
                    "maxRate": 20,
                    "clientMaxRate": 8,
                    "strategy": "ip"
            "backend": [{
                "url_pattern": "/connect/token",
                "encoding": "no-op",
                "sd": "dns",
                "host": ["identity-server.service.consul"],
                "disable_host_sanitize": true
        },

我的JavaScript请求如下所示：

    xhr.open('POST', url);
    xhr.setRequestHeader('Accept', 'application/json');
    xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
