Question

我使用了Node js express框架，在我的一个函数中，我试图通过使用http.post（）方法调用我的另一个服务器API。

大多数情况下它都能流畅地运作。但是在随机的时间;当成功响应从http post返回时，所有进行中的请求或db操作都会陷入死锁。即使Node正在运行。

现在要解决这个问题，我需要重新启动Node。 //进口

var async       = require("async");
var request       = require("request");
var wlogger     = require('../config/logger');

//功能代码

exports.sendNotification = function( req, res, next ) {
try 
{
    if (req.session && req.session.publish_UserName) {

            var data = {"request":"callback@create","data":{"userId":req.body.userId}};

            var httpReq=request.post({
                headers: {'content-type' : 'application/json'},
                url:     config.api_url,
                form:   data
            },function(error, response, body){

               wlogger.info({userName: req.session.publish_UserName, action: '/sendNotification', requestData:data, responseData :response,responseCode: '200', message: "/ - sendNotification - Notification sent"}); // write in log //
            })
            httpReq.end();
            res.send({"success": true, "status": 200, "message": "Notification sent."});


    }else{
        wlogger.info({userName: 'anonymous', action: '/sendNotification', requestData: req.body, responseData : '',responseCode: '500', message: "/ - sendNotification - Session not available "}); // write in log //
        res.redirect('/accountlogin');
    }
} catch(err){
    wlogger.error({userName: ((req.session.UserName)?req.session.Plan_UserName:'anonymous'), action: '/sendNotification', requestData: req.body, responseData : '',responseCode: '500', message: '/sendNotification catchException - '+JSON.stringify(err)}); // write in log //
    res.status(500).json(err.message);
}

}

任何帮助表示感谢。
