hey 原来被称为 boom，并且受到 Tarek Ziade 的工具 tarekziade/boom的启发。

使用同样的名字是一个失误，因为这造成了两者二进制文件名字的混淆。

为了和原作者的项目名字进行区别，我们将该项目重命名为 hey。

#### 一、安装
 github项目地址：github.com/rakyll/hey 
 
-  Linux 64-bit: https://hey-release.s3.us-east-2.amazonaws.com/hey_linux_amd64
- Mac 64-bit: https://hey-release.s3.us-east-2.amazonaws.com/hey_darwin_amd64
- Windows 64-bit: https://hey-release.s3.us-east-2.amazonaws.com/hey_windows_amd64

#### 二、软件包管理器
2.1 macOS:
Homebrew 用户可以使用 brew install hey。

#### 三、使用
hey 以预先设定的并发等级，运行预先设定数量的请求，以及打印状态。

它同时支持 HTTP2。

```go
Usage: hey [options...] <url>

Options:
  -n  Number of requests to run. Default is 200.
  -c  Number of workers to run concurrently. Total number of requests cannot
      be smaller than the concurrency level. Default is 50.
  -q  Rate limit, in queries per second (QPS) per worker. Default is no rate limit.
  -z  Duration of application to send requests. When duration is reached,
      application stops and exits. If duration is specified, n is ignored.
      Examples: -z 10s -z 3m.
  -o  Output type. If none provided, a summary is printed.
      "csv" is the only supported alternative. Dumps the response
      metrics in comma-separated values format.

-m  HTTP method, one of GET, POST, PUT, DELETE, HEAD, OPTIONS.
  -H  Custom HTTP header. You can specify as many as needed by repeating the flag.
      For example, -H "Accept: text/html" -H "Content-Type: application/xml" .
  -t  Timeout for each request in seconds. Default is 20, use 0 for infinite.
  -A  HTTP Accept header.
  -d  HTTP request body.
  -D  HTTP request body from file. For example, /home/user/file.txt or ./file.txt.
  -T  Content-type, defaults to "text/html".
  -a  Basic authentication, username:password.
  -x  HTTP Proxy address as host:port.
  -h2 Enable HTTP/2.

-host	HTTP Host header.

-disable-compression  Disable compression.
  -disable-keepalive    Disable keep-alive, prevents re-use of TCP
                        connections between different HTTP requests.
  -disable-redirects    Disable following of HTTP redirects
  -cpus                 Number of used cpu cores.
                        (default for current machine is 8 cores)
```
```go
 // 指定运行的总请求数。默认值为200。

-n  Number of requests to run. Default is 200.

// 客户端并发执行的请求数，默认为50。总请求数不能小于并发数。

-c  Number of workers to run concurrently. Total number of requests cannot

be smaller than the concurrency level. Default is 50.

// 客户端发送请求的速度限制，以每秒响应数QPS为单位，默认没有限制。

-q  Rate limit, in queries per second (QPS) per worker. Default is no rate limit.

// 发送请求的持续时长，超时后程序停止并退出。若指定了持续时间，则忽略总请求数(-n)，例如-z 10s，-z 3m

-z  Duration of application to send requests. When duration is reached,

application stops and exits. If duration is specified, n is ignored.

Examples: -z 10s -z 3m.

// 输出类型。若没有提供，则打印摘要。CSV是唯一支持的格式，结果以逗号分隔各个指标项。

-o  Output type. If none provided, a summary is printed.

"csv" is the only supported alternative. Dumps the response

metrics in comma-separated values format.

// HTTP方法，例如GET，POST，PUT，DELETE，HEAD，OPTIONS方法

-m  HTTP method, one of GET, POST, PUT, DELETE, HEAD, OPTIONS.

// HTTP请求头，可以用-H连续添加多个请求头。

-H  Custom HTTP header. You can specify as many as needed by repeating the flag.

For example, -H "Accept: text/html" -H "Content-Type: application/xml" .

// 每个请求的超时时间（以秒为单位）。默认值为20s，数值0代表永不超时。

-t  Timeout for each request in seconds. Default is 20, use 0 for infinite.

// HTTP响应头

-A  HTTP Accept header.

// HTTP请求正文

-d  HTTP request body.

// HTTP请求正文文件

-D  HTTP request body from file. For example, /home/user/file.txt or ./file.txt.

// 内容类型，默认为“ text / html”。

-T  Content-type, defaults to "text/html".

// 基本身份验证，用户名：密码。

-a  Basic authentication, username:password.

// HTTP代理地址作, 使用host:port格式。

-x  HTTP Proxy address as host:port.

// 启用HTTP / 2

-h2 Enable HTTP/2.

// HTTP主机头

-host HTTP Host header.

// 禁用压缩。

-disable-compression  Disable compression.

// 禁用保持活动状态，防止重新使用不同的HTTP请求之间的TCP连接。

-disable-keepalive    Disable keep-alive, prevents re-use of TCP

connections between different HTTP requests.

// 禁用HTTP重定向

-disable-redirects    Disable following of HTTP redirects

// 使用的cpu内核数。当前计算机的默认值为8核。

-cpus   Number of used cpu cores.

(default for current machine is 8 cores)
