项目简介

Oha是一个由Rust语言编写的轻量级HTTP负载生成器，它的灵感来源于rakyll/hey，但在此基础上增加了TUI（文本用户界面）动画，让测试结果更加直观和生动。oha利用了tokio和ratatui库，能够在高并发场景下保持优异的性能表现。同时，它还支持多种HTTP协议（HTTP/1.1、HTTP/2和HTTP/3），满足不同的测试需求。

目前在Github上收获了6.8K star！

性能特色

高效的负载生成：Oha能够快速生成大量HTTP请求，支持并发连接和HTTP/2协议，适用于各种性能测试场景。
实时TUI显示：通过TUI动画，用户可以实时监控请求的发送和响应情况，直观地了解系统的性能表现。
多平台支持：Oha支持Linux、Windows和macOS平台，用户可以在不同操作系统上无缝使用。
灵活的配置选项：用户可以通过命令行参数灵活配置请求数量、并发连接数、请求持续时间等，满足不同测试需求。

快速安装使用

安装oha非常简单，你可以根据自己的操作系统选择不同的安装方式。对于Linux和macOS用户，可以使用包管理器进行安装；而Windows用户则可以使用winget进行安装。

# Linux/macOS，使用Cargo安装（需要先安装Rust工具链）
cargo install oha

# 使用Homebrew安装（适用于macOS）
brew install oha

# Windows，使用winget安装
winget install hatoo.oha

或者到项目release页面下载对应系统的安装包即可。

安装完成后，你可以运行基本测试，比如发送200个请求到目标URL：

oha -n 200 https://baidu.com

如果你想设置并发连接数为50，可以这样做：

oha -c 50 https://baidu.com

或者，如果你想运行持续时间为30秒的测试：

oha -z 30s https://baidu.com

oha能够实时显示请求的发送数量、响应时间、错误率等关键指标，让你对系统的性能表现一目了然。

Ohayou(おはよう), HTTP load generator, inspired by rakyll/hey with tui animation.

Usage: oha [OPTIONS] <URL>

Arguments:
  <URL>  Target URL or file with multiple URLs.

Options:
  -n <N_REQUESTS>
          Number of requests to run. [default: 200]
  -c <N_CONNECTIONS>
          Number of connections to run concurrently. You may should increase limit to number of open files for larger `-c`. [default: 50]
  -p <N_HTTP2_PARALLEL>
          Number of parallel requests to send on HTTP/2. `oha` will run c * p concurrent workers in total. [default: 1]
  -z <DURATION>
          Duration of application to send requests. If duration is specified, n is ignored.
          On HTTP/1, When the duration is reached, ongoing requests are aborted and counted as "aborted due to deadline"
          You can change this behavior with `-w` option.
          Currently, on HTTP/2, When the duration is reached, ongoing requests are waited. `-w` option is ignored.
          Examples: -z 10s -z 3m.
  -w, --wait-ongoing-requests-after-deadline
          When the duration is reached, ongoing requests are waited
  -q <QUERY_PER_SECOND>
          Rate limit for all, in queries per second (QPS)
      --burst-delay <BURST_DURATION>
          Introduce delay between a predefined number of requests.
          Note: If qps is specified, burst will be ignored
      --burst-rate <BURST_REQUESTS>
          Rates of requests for burst. Default is 1
          Note: If qps is specified, burst will be ignored
      --rand-regex-url
          Generate URL by rand_regex crate but dot is disabled for each query e.g. http://127.0.0.1/[a-z][a-z][0-9]. Currently dynamic scheme, host and port with keep-alive do not work well. See https://docs.rs/rand_regex/latest/rand_regex/struct.Regex.html for details of syntax.
      --urls-from-file
          Read the URLs to query from a file
      --max-repeat <MAX_REPEAT>
          A parameter for the '--rand-regex-url'. The max_repeat parameter gives the maximum extra repeat counts the x*, x+ and x{n,} operators will become. [default: 4]
      --dump-urls <DUMP_URLS>
          Dump target Urls <DUMP_URLS> times to debug --rand-regex-url
      --latency-correction
          Correct latency to avoid coordinated omission problem. It's ignored if -q is not set.
      --no-tui
          No realtime tui
  -j, --json
          Print results as JSON
      --fps <FPS>
