K6 如何制作原始(非编码)帖子

Question

我正在尝试使用 K6 加载测试 prometheus pushgateway，它需要以下格式的帖子。

http_request_duration_seconds_bucket{le="0.05"} 24054
http_request_duration_seconds_bucket{le="0.1"} 33444
http_request_duration_seconds_bucket{le="0.2"} 100392

每行的末尾必须有一个换行符(末尾还有一个额外的) - 但是我似乎只得到 url 编码的字符串，如 %20 用于空格等。是否有可能以某种方式发布原始字符串？

Answer 1

如果您只是自己将正文构建为一个字符串并将其传递给 http.post()，则它应该按原样发送，无需任何修改。此代码应说明这一点，使用 httpbin.org:

import http from "k6/http";
import crypto from "k6/crypto";

let payload = `http_request_duration_seconds_bucket{le="0.05"} 24054
http_request_duration_seconds_bucket{le="0.1"} 33444
http_request_duration_seconds_bucket{le="0.2"} 100392
`;

export default function (data) {
    console.log(crypto.sha256(payload, "hex"));
    let resp = http.post("https://httpbin.org/anything", payload);
    console.log(crypto.sha256(resp.json().data, "hex"));
    console.log(resp.body);
}

它会输出这样的东西:
