Express.js HTTP请求超时

Question

我想知道是否有人可以告诉我使用快递时默认的HTTP请求超时是什么.

我的意思是:当浏览器或服务器手动关闭连接时,在处理http请求多少秒后,Express/Node.js服务器会关闭连接？

如何更改单个路由的超时？我想将其设置为大约15分钟,以获得特殊的音频转换路线.

非常感谢.

Answer 1

req.connection.setTimeout(ms); 似乎在Node.js中为HTTP服务器设置请求超时.

Answer 2

req.connection.setTimeout(ms); 可能是一个坏主意,因为多个请求可以在同一个插座上发送.

尝试连接超时或使用此:

var errors = require('./errors');
const DEFAULT_TIMEOUT = 10000;
const DEFAULT_UPLOAD_TIMEOUT = 2 * 60 * 1000;

/*
Throws an error after the specified request timeout elapses.

Options include:
    - timeout
    - uploadTimeout
    - errorPrototype (the type of Error to throw)
*/
module.exports = function(options) {
    //Set options
    options = options || {};
    if(options.timeout == null)
        options.timeout = DEFAULT_TIMEOUT;
    if(options.uploadTimeout == null)
        options.uploadTimeout = DEFAULT_UPLOAD_TIMEOUT;
    return function(req, res, next) {
        //timeout is the timeout timeout for this request
        var tid, timeout = req.is('multipart/form-data') ? options.uploadTimeout : options.timeout;
        //Add setTimeout and clearTimeout functions
        req.setTimeout = function(newTimeout) {
            if(newTimeout != null)
                timeout = newTimeout; //Reset the timeout for this request
            req.clearTimeout();
            tid = setTimeout(function() {
                if(options.throwError && !res.finished)
                {
                    //throw the error
                    var proto = options.error == null ? Error : options.error;
                    next(new proto("Timeout " + req.method + " " + req.url) );
                }
            }, timeout);
        };
        req.clearTimeout = function() {
            clearTimeout(tid);
        };
        req.getTimeout = function() {
            return timeout;
        };
        //proxy end to clear the timeout
        var oldEnd = res.end;
        res.end = function() {
            req.clearTimeout();
            res.end = oldEnd;
            return res.end.apply(res, arguments);
        }
        //start the timer
        req.setTimeout();
        next();
    };
}

默认请求超时时间为Node v0.9+为 2 分钟。这就是快递所使用的。

您可以使用以下方法增加单个路由的值：

app.get('/longendpoint', function (req, res) {
   req.setTimeout(360000); // 5 minutes
   ...
});
