合并 env JSON 文件以进行 newman run

Question

在我的项目中，我们为集合的每个 post 请求维护多个 JSON 文件。请求方面，我们需要这样维护以保存环境变量。我们将通过新人来运行。

我的要求是想要合并所有环境json文件并将其作为单个文件。然后，用源码（集合文件）执行它

有什么方法可以通过任何cmd注释和任何方法来合并文件

Answer 1

这个

demo.js

可以合并多个环境变量文件

合并的 JSON 文件（'demo.postman_environment.json'） 复制第一个 JSON 的属性（

id

、

name

、

_postman_variable_scope

、

_postman_exported_at

和

_postman_exported_using

）

从第 2 个到第 n 个 JSON，只需将键/值对复制到合并的 JSON 文件中。

const fs = require('fs');

// Function to merge multiple JSON objects
function mergeJSONObjects(jsonObjects) {
    const baseJSON = jsonObjects[0]; // Use the first JSON as the base structure

    // Loop over remaining JSON objects and merge their 'values' arrays into the base JSON
    jsonObjects.slice(1).forEach(json => {
        baseJSON.values = [...baseJSON.values, ...json.values];
    });

    return baseJSON;
}

// Read JSON data from files specified in command-line arguments
const jsonFiles = process.argv.slice(2); // Skip the first two args (node and script name)
const jsonObjects = jsonFiles.map(file => JSON.parse(fs.readFileSync(file, 'utf8')));

// Perform the merge
const mergedJSON = mergeJSONObjects(jsonObjects);

// Output the merged JSON
console.log(JSON.stringify(mergedJSON, null, 4));

// Optionally, save the merged JSON to a file
fs.writeFileSync('demo.postman_environment.json', JSON.stringify(mergedJSON, null, 4), 'utf8');

使用文件名参数运行它

node demo.js first.json second.json third.json

结果

demo.postman_environment.json
