WebSocket到localhost无法在Microsoft Edge上运行 [英] WebSocket to localhost not working on Microsoft Edge

问题描述

我创建了一个简单的WebSocket服务器，并尝试使用以下代码连接到它：

I've created a simple WebSocket server and am trying to connect to it with the following code:

function test(name) {
    var ws = new WebSocket('ws://localhost:1234');
    ws.onopen = function () {
        ws.send('Hello from ' + name);
    }
}
test('Edge');

这适用于Windows10上的Chrome和IE11，但是当我尝试使用Edge时， onopen 函数未被调用，而是最终我得到以下错误：

This works fine from Chrome and IE11 on Windows10 but when I try from Edge, the onopen function isn't called, instead I eventually get the following error:

SCRIPT12029：WebSocket错误：网络错误12029，无法建立与服务器的连接

SCRIPT12029: WebSocket Error: Network Error 12029, A connection with the server could not be established

版本 12.10240 边缘

有人问及类似的问题这里但错误信息不同。

A similar problem was asked about here but the error message is different.

我尝试过的事情：

• IP - localhost ， 127.0.0.1 ，实际IP


• 允许localhost环回标志 - 打开和关闭

• IP - localhost, 127.0.0.1, the actual IP
• Allow localhost loopback flag - both on and off

当尝试与另一台机器通信时，问题不会发生。

When trying to communicate with a different machine the problem does not occur.

这是Edge中的缺陷还是我做错了什么？

Is this a defect in Edge or am I doing something wrong?

推荐答案

我遇到了类似的问题，但是实际导航到浏览器中的页面时。我可以使用短语localhost，它工作正常，但当我使用我的机器名称时，我没有工作。我找到了此论坛，他们建议您在管理员提示中运行以下命令：

I had a similar problem, but it was when actually navigating to pages in the browser. I could use the phrase localhost and it worked fine, but I didn't work when I used my machine's name. I found this forum where they suggested that you run the following command in a administrator prompt:

CheckNetIsolation LoopbackExempt -a -n=Microsoft.MicrosoftEdge_8wekyb3d8bbwe

为我工作。您可能会看到某种形式的同一问题。

Worked for me. Thought you might be seeing some form of the same issue.

正如论坛建议的那样，您现在也可以通过打开Edge并导航到 about：flags ，然后在Developer Settings下勾选允许localhost环回（这可能会使您的设备面临风险）。应该感觉比将随机内容粘贴到命令提示符更安全。

As the forum suggests, you can now also do this by opening Edge and navigating to "about:flags", then tick "Allow localhost loopback (this might put your device at risk)" under "Developer Settings". Should feel a little safer than pasting random stuff into your command prompt.

编辑：正如tresf指出的那样，环回about：flags中的复选框似乎已停止工作（作为修复），因此您将使用CheckNetIsolation命令，以使Edge免除。

As tresf pointed out below, the loopback checkbox in the about:flags appears to have stopped working (as a fix), so you'll have use the CheckNetIsolation command, to make Edge exempt.
