Question

这是我的代码：

app.use(function(req, res, next) {
    res.header('Access-Control-Allow-Origin', 'http://localhost:3000');
    res.header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
    res.header('Access-Control-Allow-Headers', 'Content-Type');
    res.header('Access-Control-Allow-Credentials', true);
    next();
});

app.post('/cookie',function(req, res){
    res.cookie('test', 'cookie_value', {httpOnly: false});
    return res.send('cookie has been set!');
});

那是在服务器端。作为客户端，我正在发送POST请求：

fetch('https://MyServer.com/cookie', {
            method: 'POST',
            credentials: 'include',
            headers: {
                'Content-Type': 'application/json',
                'Accept': 'application/json'
            },
            body: JSON.stringify(userData)
        });

我想将Cookie作为客户端。问题是我可以得到“已设置cookie！”作为答复，但没有cookie，也没有“ Set-Cookie”标头或类似的内容。在“应用程序”选项卡中查看F12 devtools时，我发现没有cookie，“网络”选项卡中的响应也如下所示：

Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: GET, POST, PUT, DELETE
Access-Control-Allow-Origin: http://localhost:3000
Connection: keep-alive
Content-Length: 20
Content-Type: text/html; charset=utf-8

怎么了？

我无法使用NodeJS / express res.cookie（'Name'，'Value'）;发送cookie
