curl命令及返回
基本指标
curl URL #获取该网址的文本信息
-i URL #获取该网址的文本信息以及协议头部信息
-x 47.94.151.148:80 zhujy.com.cn #使用代理获取网页文本信息
-I url #仅返回请求头部信息
-C/–continue-at # 断点续转
-v #参数可以显示一次http通信的整个过程，包括端口连接和http request头信息
-V #show the version of curl
常用命令
curl -O http://10.167.209.1:1212/hongtabank/ #下载指定ip底下的hongtabank文件
curl www.zhujy.com #获取该网址的文本信息
这就是获取的www.zhujy.com信息

<div>下面是五个关于前端相关的基础问题，但却很能体现JavaScript的基本功底。
问题1：Scope作用范围
考虑下面的代码：
(function() {
var a = b = 5;
})();
console.log(b);
什么会被打印在控制台上？
回答：
上面的代码会打印 5。

<div>本篇，不考虑细节问题和为什么，先照葫芦画瓢写一个Thrift版本的Hello World，了解Thrift RPC服务开发的基本流程
1. 在Intellij中创建一个Maven模块，加入对Thrift的依赖，同时还要加上slf4j依赖，如果不加slf4j依赖，在后面启动Thrift Server时会报错

<div>本文的目的主要是总结下基于Avro Schema代码生成，然后进行序列化和反序列化开发的基本流程。需要指出的是，Avro并不要求一定得根据Schema文件生成代码，这对于动态类型语言很有用。

最大连接数也是一样的，增加maxThreads属性即可，如下，配置如下：

<div>一、低延迟的客户端-服务器 和 服务器-客户端的连接
很多时候所谓的http的请求、响应的模式，都是客户端加载一个网页，直到用户在进行下一次点击的时候，什么都不会发生。并且所有的http的通信都是客户端控制的，这时候就需要用户的互动或定期轮训的，以便从服务器端加载新的数据。
通常采用的技术比如推送和comet（使用http长连接、无需安装浏览器安装插件的两种方式：基于ajax的长</div>
