接口压力测试工具之go-wrk

　　go-wrk 是一个用Go语言实现的轻量级的http基准测试工具，类似于wrk，本文将简单介绍一下如何使用go-wrk实现接口的性能(压力)测试。

github地址：https://github.com/tsliwowicz/go-wrk

安装：

go get github.com/tsliwowicz/go-wrk 

使用：

Usage: go-wrk <options> <url>
   Options:
    -H      header line, joined with ';' (Default )
    -M      HTTP method (Default GET)
    -T      Socket/request timeout in ms (Default 1000)
    -body      request body string or @filename (Default )
    -c      Number of goroutines to use (concurrent connections) (Default 10)
    -ca      CA file to verify peer against (SSL/TLS) (Default )
    -cert      CA certificate file to verify peer against (SSL/TLS) (Default )
    -d      Duration of test in seconds (Default 10)
    -f      Playback file name (Default <empty>)
    -help      Print help (Default false)
    -host      Host Header (Default )
    -http      Use HTTP/2 (Default true)
    -key      Private key file name (SSL/TLS (Default )
    -no-c      Disable Compression - Prevents sending the "Accept-Encoding: gzip" header (Default false)
    -no-ka      Disable KeepAlive - prevents re-use of TCP connections between different HTTP requests (Default false)
    -redir      Allow Redirects (Default false)
    -v      Print version details (Default false)

./go-wrk -c 80 -d 5  http://192.168.1.118:8080/json

持续5秒中， 开启每秒80个并发请求

返回结果：
Running 10s test @ http://192.168.1.118:8080/json  
  80 goroutine(s) running concurrently  
   142470 requests in 4.949028953s, 19.57MB read  
     Requests/sec:        28787.47  
     Transfer/sec:        3.95MB  
     Avg Req Time:        0.0347ms  
     Fastest Request:    0.0340ms  
     Slowest Request:    0.0421ms  
     Number of Errors:    0  
还有其他参数：  -n 10000  就是模拟1w次请求
