Javascript k6脚本：如何解析用于HTTP查询的文件信息

我对k6是新手，对JS是新手。我试图从一个平面文件中读取一个列表，该平面文件是我从DB中的一列导出的。我想打开这个文件，并在列表中循环，将每个项目作为HTTP调用的查询参数追加。我想不出怎么继续

例如，如果这是我的文件：

employees.txt

01111
02222
06666
04444
09999

&这是我的k6脚本（perf employee.js）

任何关于继续操作的指导都将不胜感激。

open（）

一个简单的字符串（如果使用

b

标志，则为二进制），因此您只需使用JavaScript

string.split（）

方法将其转换为数组（它自己的数组行中的每一行）即可对其进行解析。或者，如果您想读取更复杂的数据文件，请使用JSON和

JSON.parse（）

方法将其直接转换为JavaScript对象—请查看上面链接中的第一个示例

然后通过使用k6，您可以执行以下操作：

import http from "k6/http";
import { sleep } from "k6";

var data = open("./employees.txt").split(/\r?\n/);

export let options = {
    vus: 3,
    duration: "5s"
};


export default function () {
    var employee = data[__ITER % data.length];
    console.log(`VU ${__VU} on iteration ${__ITER} has employee ID ${employee}...`)
    http.get(`http://www.example.com/employee?employee_num=${employee}`);
    sleep(1);
};

您应该可以在脚本输出中看到如下内容：

INFO[0001] VU 2 on iteration 0 has employee ID 01111... 
INFO[0001] VU 1 on iteration 0 has employee ID 01111... 
INFO[0001] VU 3 on iteration 0 has employee ID 01111...

令人惊叹的！谢谢+1我们好！谢谢+1.
