我有一个快递4应用程序,我试图实现http2 / SPDY。
www(创建服务器的地方):
var spdy = require('spdy');
var options = {
/* certs */
}
var server = spdy.createServer(options,app).listen(8081);
index.js:
var asset = fs.readFileSync("public/js/asset.js");
router.get('/test', function(req,res) {
if (req.isSpdy) {
var headers = {'content-type': 'application/javascript'};
res.push('/js/asset.js', headers, function(err,stream) {
if (err) {
console.log(err);
return;
}
stream.end(asset);
});
}
res.render('test', {});
});
现在这一切在正常使用场景中完美无缺。使用SPDY indicator plugin我可以看到我的网站是通过HTTP / 2提供的。我也能看到PUSH_PROMISES适用于指定的资产文件。它的性能提升非常棒。
但是,当客户端中止请求时会出现问题。通过在浏览器中快速按下刷新/停止,可以轻松复制。在这种情况下,我收到以下错误,导致我的节点应用程序崩溃:
events.js:141
throw er; // Unhandled 'error' event
^

如果我注释掉res.push()
次调用,则代码按预期工作,没有错误。
我给了npm spdy-push
包装器模块(它说它处理连接关闭)一次尝试,但它根本不起作用。如文档所示设置时,会导致以下错误:

有没有人对我可能做错了什么,我应该如何处理已中止的请求,或者为Express提供http2 / spdy PUSH_PROMISE支持的其他模块有任何想法?
答案 0 :(得分:0)
在与npm-spdy
的开发人员交谈之后,它似乎已经破了。
