URI介绍 URI(Uniform Resource Identifier),是统一资源标识符的缩写,是一个用于标识某一个Web资源名称的字符串,该标识允许用户对任何资源通过特定的协议进行交互。Web上可用的每种资源,如:HTML、图像、视频和音乐等资源,都由一个统一资源标识符进行标识。URI一般由三部分组成: ● 访问资源的命名机制 ● 存放资源的主机名 ● 资源自身的名称,由路径标识,着重强调于资源 URL介绍 URL(Uniform Resource Locator),统一资源定位符的缩写,URL是一种特殊类型的URI,包含了用于查找某个资源的全部信息。URL一般由三部分组成: ● 协议类型 ● 主机的IP地址(可以包含端口号) ● 资源路径 HTTP之URL HTTP使用统一资源定位符URL来传输数据和建立连接,以下面这个URL为例,为大家介绍下URL的各部分组成: http://www.itxdl.cn:8080/news/index.jsp?boardID=5&ID=24618&page=1#name 从上面的URL中可以看出,一个完整的URL包括以下几部分: ● 协议部分:该URL的协议部分为“http”,这代表网页使用的是HTTP协议,在Web中可以使用多种协议,如HTTP、FTP等等,在协议后面的“//”为分隔符。 ● 域名部分:该URL的域名部分为www

Nginx配置文件(nginx.conf)配置详解

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> user nginx nginx ; Nginx 用户及组:用户 组。window下不指定 worker_processes 8; 工作进程:数目。根据硬件调整,通常等于CPU数量或者2倍于CPU。 error_log logs/error.log; error_log logs/error.log notice; error_log logs/error.log info; 错误日志:存放路径。 pid logs/ nginx.pid; pid (进程标识符):存放路径。 worker_rlimit_nofile 204800; 指定进程可以打开的最大描述符:数目。 这个指令是指当一个nginx进程打开的最多文件描述符 数目,理论值应该是最多打开文件数(ulimit -n)与nginx进程数相除,但是nginx分配请求并不是那么均匀,所以最好与ulimit -n 的值保持一致。 现在在linux 2.6内核下开启文件打开数为65535,worker_rlimit_nofile就相应应该填写65535。 这是因为nginx调度时分配请求到进程并不是那么的均衡,所以假如填写10240,总并发量达到3-4万时就有进程可能超过10240了,这时会返回502错误。 events { use epoll;

问题 In implementing OAuth2 in my app, I need to handle URIs like: http://localhost:3000/sessions/create/?code=lorem|ipsum Not sure if it's a Rails 3 or Ruby 1.9.2 problem (maybe URI.parse), but in any event, WEBrick kicks Error bad URI . Anyone know of a workaround? Thanks. 回答1: I ran into the same requirement (and problem) recently. On Rails 3 and Ruby 1.9.2.

Get html that is generated via AJAX in webclient

风格不统一 提交于 2019-12-18 08:57:17
问题 I often go to a site to look stuff up. I thought to myself: "Hold on. I can program. Why am I going to this site manually when I can write a piece of software that does it for me?". And so I started. I'm using C#, so I found WebClient and Uri. I've managed to get the source code for the site, yet the problem occurred that the specific data I'm looking for is generated via AJAX, after the source code has loaded. So that's my problem. How can I get that code, if it needs to be requested via an

Anything start with http:// is validated by FILTER_VALIDATE_URL?

巧了我就是萌 提交于 2019-12-18 08:23:46
问题 I tested with strings and int that I can imagine, as long as it start with http://, it will be a valid url using FILTER_VALIDATE_URL. So, why we need FILTER_VALIDATE_URL? Why not just add http:// on an input whenever we want to make it valid? var_dump(filter_var ('http://example',FILTER_VALIDATE_URL )); 回答1: Well technically, any URI that starts with a scheme (like http:// ) and contains valid URI characters after that is valid as per the official URI specification in RFC 3986: Each URI
