问题 
.js 
 因为我需要提取响应并保存到文件中,所以下面是我使用的脚本 
- var fs = require('fs'),
 
 -     newman = require('newman'),
 
 -     results = [];
 
  
- newman.run({
 
 -         reporters: 'cli',
 
 -         collection: '/Users/prasad/Documents/migration/export_uuid_emails.postman_collection.json',
 
 -         iterationData: '/Users/prasad/Documents/migration/test.csv',
 
 -         //data: '/Users/prasad/Documents/migration/test.csv', // this also doesn't work
 
 -         iterationCount: 1,
 
 -         //iterationCount: 2, // this is iterting the same data two times
 
 -         environment: '/Users/prasad/Documents/migration/stage.postman_environment.json'
 
 - }).on('request', function(err, args) {
 
 -         if(!err) {
 
 -                 var rawBody = args.response.stream,
 
 -                  body = rawBody.toString();
 
  
-                 results.push(JSON.parse(body));
 
 -         }
 
 - }).on('done', function(err, summary) {
 
 -         fs.writeFileSync('migration-report.json', JSON.stringify(results, null, 4));
 
 - });

下面是 test.csv 的内容 
- userId
 
 - 0e4aab3a-62cb-4e23-8f44-40b1f1c5f9eb
 
 - a1d3e402-a83f-4918-9b7c-333d281be35d

下面是环境文件 
- {
 
 -     "id": "8e50b25f-df1a-4c15-abe9-1f8e4728da13",
 
 -     "name": "stage",
 
 -     "values": [
 
 -         {

 -             "value": "https://stage.api.auth.aws.pen.com",
 
 -             "enabled": true
 
 -         },
 
 -         {
 
 -             "key": "accountStatus",
 
 -             "value": "active",
 
 -             "enabled": true
 
 -         }
 
 -     ],

 -     "_postman_exported_at": "2020-03-16T10:51:49.468Z",
 
 -     "_postman_exported_using": "Postman/7.20.0"
 
 - }

根据脚本,它应该为两个 userId 执行,但它始终只为第一个 userId 执行,我尝试使用 2 执行迭代计数,但它为同一个 id 执行两次。 
 
我遵循了纽曼的文档和参考资料,请问有人可以在这方面帮助我吗? 
 
谢谢,普拉萨德 
 
回答 
在尝试了不同的方法之后,我想这是因为即使你不提供 
 
下面是我的理解 
- test.csv
 
 -  file are 3
 
 - So it's choosing those many no.of entries which is equal to 
 
 - iterationCount if you don't specify any value then it's looping all entries which is 3 in this case.
 
  
- iterationCount
 
 -  whenever you are providing 
 
 - iterationData then it is working.
 
  
- iterationCount: 1
 
 -  when i changed that to 
 
 - iterationCount: 0 it started working.
