Node js infinite loop

由 岁酱吖の 提交于 2021-02-08 10:17:44
问题 I have a node server that pulls info from a php server and sends it over where it needs to be through a callback. Once or twice ad day the server gets stuck in an infinite loop and I think it's because I'm not properly handling the connection between the the php and node server. I posted my authentication code below. Anyone have any ideas? exports.authenticate = function(request, callback) { var https = require('https'); var options = { hostname: 'www.mysite.com', port: 443, path: '/site

How to fix infinite loops when user enters wrong data type in scanf()?

由 一笑奈何 提交于 2020-06-17 05:29:08
问题 C beginner here. For the program below, whenever the user inputs a character or a string it enters an infinite loop. How would you fix this while still using scanf? And what would be the better methods of writing this program rather than using scanf? Thanks to those who will answer. #include <stdio.h> #include <ctype.h> int main() { int rounds = 5; do { printf("Preferred number of rounds per game. ENTER NUMBERS ONLY: "); scanf("%d", &rounds); } while(isdigit(rounds) == 0); return 0; } 回答1: I

img dynsrc

由 北城余情 提交于 2020-03-13 07:01:03
不过只在IE和Netscape中支持，Firefox会提示proprietary attribute （一）基本语法： 　　img dynsrc=url 　　说明：img dynsrc可以用来插入各种多媒体，格式可以是Wav、Avi、AIFF、AU、MP3、Ra、Ram等等。url为音频或视频文件及其路径，可以是相对路径或绝对路径。 　　示例：<img dynsrc="your.avi"> （二）属性设置： 　　 1、预设图片： 　　语法：src=url 　　说明：url为图片文件及其路径，可以是相对路径或绝对路径。该属性的作用是当视频文件下载时，用图片占据视频文件的显示位置；视频文件下载完成，图片被屏蔽，显示视频文件。若指定dynsrc为一个音频文件之后，src属性就被屏蔽，图片就不可见了。 　　示例：<img dynsrc="your.avi" src=logo.jpg> 　　 2、播放事件： 　　语法：start=fileopen、mouseover 　　说明：该属性规定了文件播放的事件，缺省值是fileopen。也可以两者同时设置。另外，用鼠标在播放区域点击一下，也将令浏览器开始播放该文件。 　　fileopen：文件打开时； 　　mouseover：鼠标移到播放区域上时。 　　示例：<img dynsrc="your.avi" start=fileopen> 　　<img
