# 概述：一共三大部分配置。
# 其中#注释掉的可以在需要的时候开启并修改，没有注释掉的（除了下面location示例）不要删掉，基本都是必须的配置项。

###############################第一部分 全局配置############################
#user  nobody;                        指定启动进程的用户，默认不用指定即可。
#error_log  logs/error.log;           配置日志输出，虽然叫error_log但是可以定义输出的级别，默认不写是ERROR级别
#error_log  logs/error.log  notice;   
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;           记录pid的文件，默认就是放到这个位置，可以修改。

-- 直接赋值是全局变量一般不要这么使用
a = 10 
-- local是指定当前作用域（一般指大括号或当前文件内）有效的变量
local a = 10

-- 数字
local b = 10.1
print(a + b) -- 打印20.1，支持常见的运算符以及位运算符
print(15 & (1<<2)) -- 4

<?php
  /**
   * getRandomWeightedElement()
   * Utility function for getting random values with weighting.
   * Pass in an associative array, such as array('A'=>5, 'B'=>45, 'C'=>50)
   * An array like this means that "A" has a 5% chance of being selected, "B" 45%, and "C" 50%.
   * The return value is the array key, A, B, or C in this case.  Note that the values assigned
   * do not have to be percentages.  The values are simply relative to each other.  If one value
   * weight was 2, and the other weight of 1, the value with the weight of 2 has about a 66%
   * chance of being selected.  Also note that weights should be integers.

I needed to quickly encode a protobuf from the command-line, and while I pretty much immediately came across protoc --encode as the obvious solution, I did not find much documentation on the input textual syntax.

Here is the relevant snippet from protoc --help:

--encode=MESSAGE_TYPE       Read a text-format message of the given type
                              from standard input and write it in binary
                              to standard output.  The message type must
                              be defined in PROTO_FILES or their imports.

// Package deepcopy provides a function for deep copying map[string]interface{}
// values. Inspired by the StackOverflow answer at:
// http://stackoverflow.com/a/28579297/1366283
//
// Uses the golang.org/pkg/encoding/gob package to do this and therefore has the
// same caveats.
// See: https://blog.golang.org/gobs-of-data
