循环内的nodejs请求函数

我有每个都有8个项目的数组

var array_pullrequest_id=["335","328","326","323","322","314","295","291"];
var array_uniqueName=["[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]"];

我正在尝试对数组的每个索引进行发布请求：

 function test2(){
   
    var array_pullrequest_id=["335","328","326","323","322","314","295","291"];
    var array_uniqueName=["[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]"];
    var count = 8;
     for (var i=0; i<count; i++){
     
    var pullRequests_id = array_pullrequest_id[i];    
    var createdBy = array_uniqueName[i];
  
  console.log("first index: " + i);
  console.log("first console log pullRequest ID: " + pullRequests_id);
  console.log("first console log Created by: " + createdBy);

  var options = {
  'method': 'GET',
  'url': 'https://HIDEN_URL/pullRequests/'+ pullRequests_id+'/workitems',
  'headers': {
    'Authorization': 'Basic HIDEN_AUTH',
    'Cookie': 'HIDEN_COOKIE'
  }
}
request(options, function (error, response) { 
    console.log("second index: " + i);
    console.log("second console log pullRequest ID: " + pullRequests_id);
    console.log("second console log Created by: " + createdBy);

});
}
 }

现在，这是控制台输出：

first index: 0
first console log pullRequest: 335
first console log Created by: [email protected]
first index: 1
first console log pullRequest: 328
first console log Created by: [email protected]
first index: 2
first console log pullRequest: 326
first console log Created by: [email protected]
first index: 3
first console log pullRequest ID: 323
first console log Created by: [email protected]
first index: 4
first console log pullRequest ID: 322
first console log Created by: [email protected]
first index: 5
first console log pullRequest ID: 314
first console log Created by: [email protected]
first index: 6
first console log pullRequest ID: 295
first console log Created by: [email protected]
first index: 7
first console log pullRequest ID: 291
first console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]
second index: 8
second console log pullRequest ID: 291
second console log Created by: [email protected]

现在，您可以看到第一个控制台日志项在count变量索引之后正确打印，但是在for循环请求功能（第二个控制台日志）中，它仅打印最后一个数组项，即使它在循环中，也只是将最后，这对我来说毫无意义...

假设您已经安装了axios，则可以使用async / await，如下所示

注意async关键字在function test2()

现在test2是一个异步功能

const axios = require('axios');

async function test2(){
   
    var array_pullrequest_id=["335","328","326","323","322","314","295","291"];
    var array_uniqueName=["[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]","[email protected]"];
    var count = 8;
    for (var i=0; i<count; i++){

        var pullRequests_id = array_pullrequest_id[i];    
        var createdBy = array_uniqueName[i];

        console.log("first index: " + i);
        console.log("first console log pullRequest ID: " + pullRequests_id);
        console.log("first console log Created by: " + createdBy);

        var options = {
        'method': 'GET',
        'url': 'https://HIDEN_URL/pullRequests/'+ pullRequests_id+'/workitems',
        'headers': {
        'Authorization': 'Basic HIDEN_AUTH',
        'Cookie': 'HIDEN_COOKIE'
            }
        }
        await axios(options)
        .then(() => {
            console.log("second index: " + i);
            console.log("second console log pullRequest ID: " + pullRequests_id);
            console.log("second console log Created by: " + createdBy);
        })
        
    }
 }
